Show spines tipped with reddish fuscous. Length of body, 13mfU; of autennaj, 10.5nim; of pronotum, 3mm ; of tegmina, 15.75mm ; of hind tibiae, 8mm. 2 $, Northern New Mexico, August to September, Lieut. W. L. Carpenter. 44. Trimerotropis ob& cura, nov. sp.- Pale brownish cinereous, the under surface and mouth- parts paler; head dotted profusely, pronotum less profusely, with blackish specks; an inconspicuous dusky stripe behind the middle of the eye; antennae nearly as long as the hind tibia1, annulate with pallid and fuscous. Deflected lobes of pronotum with a very small blackish or fuscous, central, longitudinal bar. Tegmina sprinkled profusely with blackish fuscous dots, partially collected into three, equidistant, indistinct, dusky clouds, the middle one in the middle of the wing; wings pale yellowish at base, beyond the middle with a very broad fusco- fuliginous band, in the preanal area seuding a broad, tapering, rather bhintly- tcrminating shoot more than half- way toward the base; the inner margin of the baud otherwise scarcely arcuate, at the lower margin scarcely extended toward the anal angle; apex of the wing faintly fuliginous, the veins blackish. Hind femora with exceedingly faint, dusky, broad, transverse, oblique bands on the outer face, made more distinct on the upper surface by a sprinkling of black dots, which also uiaik the inferior outer and inferior carina*; hind tibia* of the color of the femora, infuscated at tip, the spines black, excepting at base. Length of body, 27mm; of antenna?, l;> n, n,; of pronotum, 6.5mm; of tegmina, 29lljm (?); of hind tibfce, 13mm. 1 9 , Northern New Mexico, August to September, Lieut. W. L. Carpenter. This species in its coloration, and especially in the broad band of the wings, has much the aspect of an Jrphia. The single specimen obtained is somewhat mutilated, but it is so distinct from any species known to me that I venture to describe it. 45. Trimerotropispseudofasciata, nov. sp.- Brownish cinereous, more or less dotted with fuscous, the middle of the deflected lobes of the pronotum with a quadrate, blackish spot, followed beneath by yellowish; antenna) more or less distinctly annulate with fuscous. Tegmina extending far beyond the tip of the abdomen, with two transverse, blackish, fuscous bands, one median, the other in the middle of the basal halt', tapering anteriorly, the inner edge of the inner one usually distinct, and always followed basal ly by a profuse sprinkling of fuscous dots; apical two- fifths similarly sprinkled, but with slightly larger quadrate spots, often irregularly clustered into spots, nearly or quite as conspicuous in the middle area as toward either border; wings very pale yellow at base, beyond pellucid, with a faint, slightly irregular, snbarcuate, mesial band, made up altogether of the darkening ( to blackish fuliginous) of the veins of this portion, and occasionally by a slight smokmess of the neighboring cells; the veins of the apex of the wing are again darkened, though not to so great an extent. Hind femora with three obscure, brownish, transverse, oblique belts on the outer face, sparsely sprinkled with blackish dots, becoming more distant, though still not very conspicuous, on the upper fact*; hind- tibite yellow, fully one- half of the spines black apicallv.

Loew. I have other specimens (<?, $) collected by Dr. Edw. Palmer, at San Diego, Southern California, in July. [ This species should not be confounded with a hitherto undescribed species from Tighes Station and Julian, Southern California, collected by Dr. Palmer, which I have marked in my collection as Trimerotropis Juliana. This latter species has the transverse bands of the wings formed of a rather faint fuliginous shade in the cells, than which the veins are scarcely darker ; the contrast of colors upon the tegmina is greater, and the large dark spots are, if anything, broader next the costa, and certainly as distinct there as anywhere ; the inner margin of the inner bar is nearly lost in the flecking of the base, and the spots of the apex of the tegmina are wholly or almost wholly confined to the upper and lower margins. The hind tibiae have also a distinct, dark, basal annulus, and, finally, the median carina of the anterior lobe of the pronotum is not so elevated. In other respects, the two species can scarcely be distinguished; and one of the San Diego specimens of T. pseudofasciata approaches T. Juliana in having the cell* in the banded area of the wings almost wholly fuliginous; but the veins, on the other hand, are so conspicuously darker than the fuliginous membrane that the resemblance is not so great as it otherwise would be; and, in other respects, the specimen conforms to the type of T. pseudofasciata. The two species agree in size.] ANCONIA, (&} x<*), nov. gen. Head rather small, unusually smooth ; space between the eyes above equal to twice the extreme width of the basal joint of the an tenure; fastigiuin nearly flat, a little transversely sulcate between the middle of the eyes, the lateral carinie somewhat elevated but blunt, bent slightly inward and less elevated beyond the eyes, continuous with the outer margins of the flat frontal costa ; the latter is as broad above as the basal joint of the antennre, expands a little just above the ocellus, below which it contracts ( in the 9 to nearly half its greatest width), and remains of the same width nearly to the clypeus; in this contracted portion, it is sulcate; lateral foveotoe flat; lateral ocelli very large; eyes large, ovate, very prominent; antennre moderately short, |
