Show 263 above with orange. Length of body, 15mm; of antennae, 8.25mm; of tegmina, 8.25mm; of hind femora, 10mm. A single male was taken in the Garden of the Gods, Colo., July 13. 15. Scyllina delicatula nov. sp. Fastigium of vertex moderately broad, with prominent margins, slightly approaching each other in a curve posteriorly, acute- angled in front; lateral foveolae rather large, rhomboidal, closely approximate; frontal costa with straight sides, regularly divergent, rather deeply sulcate, sparsely punctate, like the rest of the face; cheeks smooth ; antennae about as long as the head and pronotum together. Pronotum obtuse- angled posteriorly, the median carina equal, moderately prominent, severed scarcely in advance ot the middle; the lateral lobes with a secondary, blunt, irregular, rugulose carina, extending from a little above the middle of the front border to the posterior extremity of the lateral carinre. Color dusky- brown above, ashen or yellowish brown below, the front pallid brownish, the cheeks and vertex livid, the latter with a pair of dusky streaks extending backward from the lateral carina of the fastigium. Pronotum enlivened above with a reddish tinge, the lateral lobes more or less marked with blackish above, the lower third pale yellowish, with a yellowish longitudinal ruga on the middle of the posterior half. Tegmina surpassing the femora, fuligino-pellucid, flecked with small, quadrate, more or less distinct, blackish spots ( along the median area, the base of upper area and the veins brown ; ' wings scarcely shorter than the tegmina, pellucid, with a slight fuliginous stigma next the extremity of the front margin, the veins of the upper half of the wing blackish. Hind femora extending much beyond the abdomen, bluish livid, with a basal dash, and an oblique premedian streak of black on the outer side and above, and a slight infuscation along the upper margin; bind tibire pale reddish, the color fading toward the base; spines tipped with black. Length of body, 12.5mm; of antenna, 5mm; of tegmina, 13mm ; of hind femora, 8.5ram. 2 <?, Garden of the Gods, Colo., July 13. 16. Arphia luteola JScndd. 1 <?, Denver, Colo.; 1 9, Utah. 17. Arphia arcta nov. sp. Head grayish- brown above, yellowish elsewhere, the median carina of vertex broken at the posterior limit of the fastigium by the deeply- impressed, arcuate, transverse furrow, which marks the same, extending through the frontal costa nearly to the ocellus, expanding and forming an oval loop at the extremity; lateral foveolae strougly depressed, narrowing interiorly. Pronotum grayish- brown, the upper surface unusually flat for an Arphia, rugulose, the median carina but little elevated, not laterally pinched in the middle, regularly, though but slightly, diminishing in height posteriorly. Tegmina profusely sprinkled with very small grayish- fuscous spots, less abundant apically, where it is pellucid. Wings yellow at the base, pellucid to an unusual extent at the tip ( nearly one- third of the anteanal field is included in the pellucid area), making the transverse dusky band narrower than in any species of Arphia known to me; the radial shoot toward the base is, however, unusually broad and long, equaling at its origin the entire breadth of that part of the wing, and scarcely stopping short of the base. Hind femora brownish- yellow externally, with two broad, a little oblique, dusky, transverse bands; hind tibice pale yellow, with a broad fuscous cloud at the tip and just before the middfe. Length of body, 21mm; of antennae, 8.5mro; of tegmina, 22.5mln; of hind femora, 11.5mm. 1 <?, Deuver, Colo. This species is more closely allied to the preceding than to any described species, but is smaller and differs from it in the narrowness of |
