Marahallii. Alxlomen yellowish beneath, mostly reddish brown above, deepening into black; last abdominal segment of male terminating with a quadrate, slightly and broadly . notched margin ; anal cerci of male short, very broad, nearly equal, strongly compressed, laminate, the tip broadly rounded, slightly incurved, so that the outer margin is broadly convex, the inner Bhallowly concave.

W. L. Carpenter. This species might easily be confounded with the preceding, but is distinct from it in the character of the tegmina, the dorsum of the pronotum, and the anal cerci of the male. 19. Pezotettix plagows, nov. sp.- Brownish yellow marked with dark brown or brownish fuscous; especially noticeable is a medio- dorsal dark stripe, extending from tbe middle of the vertex between the eyes, where it is not half eo broad as the vertex, to or nearly to the end of tbe pronotum, broadening as it goes, on the posterior half of the pronotum inclosing a median pale line and fading out at the extremity of the posterior lobe; and also a broad belt at the upper limit of the deflected lobes in front of the posterior sulcus extending forward to the eye and fading inferiorly. Vertex between the eyes slightly broader than the frontal costa; fastiginm broadly and rather Bhallowly sulcate, the frontal costa equal, narrowly Bulcate below the ocellus. Pronotum broadening slightly posteriorly, the posterior lobe punctate, the median carina distinct only on this lobe, and their slight lateral carinas moderately abrupt, r obtuse, the posterior border obtusely angulated, the angle rounded; prosternal spine very short, straight, stout, pyramidal, pointed. Tegmina not much shorter than the abdomen, obscure brown, mottled with many paler and darker spots ( due to the color of the veins), mostly arranged longitudinally in the median field; tbe costal field is broadly swollen near the base, and beyond it the whole wing tapers nearly to the rounded tip; wings well formed, the veins of the apieal half of tbe Ereanal field dusky or blackish. Hind femora with two median, angnlate, moderately road, brownish fuscous bands, the arc of the geniculation black; hind tibiffi pale dull glaucous, pale at the base, the spines black- tipped. Anal cerci of male broad at base, rapidly tapering on basal compressed conical half, very slender and nearly equal on the apical half, a little incurved at tip.

Pezotettix marginaius, nov. sp.- Dull pale olivaceous brown, slightly darker above, with a broad black stripe, occasionally obsolescent, extending from behind the eye, along the upper border of the deflected lobes of pronotum,- to the posterior transverse sulcus; pleura sometimes marked with black and the abdomen with a lateral black band, sometimes continuous and equal, sometimes confined to small triangular spots on the segments of the anterior half; hind femora sometimes a little infuscated externally, the genicular lobes sometimes blackish, the hind tibiae rather dark olivaceous, the apical half of the spines black; the summit of the head is sometimes marked with black in broad median and diverging supraorbital stripes. Face unusually oblique, forming, with the descending fastiginm of the vertex, a little more than a right angle; fastiginm rather deeply channeled iu the male, slightly in the female; frontal costa equal, shallowly sulcate throughout. Pronotum rather long, the dorsum equal, with slightly sloping sides, distiuct but rather slight and equal median carina and distinct though very obtuse lateral carinae; hind border scarcely anguiate; prosternal spine rather small, bluntly subcorneal, inclined a little backward. Tegmina ajittle longer than the pronotnm, simple, but at tbe extreme tip a little pinched, and tapering to a blunt point; wings a little shorter. Hind legs rather slender, the femora compressed. Last abdominal segment of male terminating in a pyramidal point; anal cerci of same straight, rather stout, moderately long, noticeably but broadly constricted in the middle, the tip larger than the base, gibbous, the whole scarcely depressed, curving slightly down ward beyond the middle.

Pezotettix vivctx, nov. sp.- Head large, prominent, yellowish green, mottled wiwi brown, which on the summit forms a very broad longitudinal stripe; vertex between the eyes as broad as the frontal costa, the fastigium slightly sulcate, the frontal costa equal, rather deeply sulcate below the ocellus; antennae light brown, the basal joins unusually small. Pronotum small, equal, compressed, the dorsum flat, the whole so much smaller than the head as to give the insect a strangulated appearance, bro^ nisa |
