78 PEOF. P. B. UHLER ENUMERATION OF THE [Jan. 15, Length to end of venter 3^ mm., to tip of wing-covers 5 mm.; width of pronotum 1 m m . Five specimens, all females, were secured on the island. One was taken at an altitude of 1500 feet above the sea, and two were collected at Kingstown. DELTOCEPHALUS VIBGULATUS, sp. nov. Form short, robust; head bluntly subcorneal, black, striped with green, polished; the wing-covers coriaceous throughout, wide at tip and bluutly rounded. Head of about the same length as pronotum, the vertex hardly separated from the front, depressed at base, where it is crossed by a pale green band; front convex, dull black above, green across the end, and there forming a part of the broad band which covers all but the tip of the clypeus and tip of the wide cheeks ; rostrum orange, reaching to the middle coxse. Pronotum transverse, convex, curved over the head to before the middle of the eyes, minutely wrinkled, crossed by a green band which covers most of the surface and sometimes includes the posterior margin. Scutellum dull black, transversely incised, pale at tip. Legs black, the posterior tibia? with pale spines, and the tarsi more or less pale. Pleural segments more or less marked with pale green. Wing-covers thick, coarsely scabrous, and obsoletely punctate, so broadly marked with green as to give predominance to that colour, the black shows as a broad apical border; a wide angular spot curving apically from the costal border, a streak near tip of inner areole, an oblique stripe at outer border of clavus, a spot at base of corium, and a streak at base of clavus, all black; wings smoky. Venter black, the edges and outer border of segments pale greenish ; last segment of male sinuated, genitalia blunt. Length to tip of wing-covers 3-3| m m . ; width of pronotum 1 mm. Eight specimens of this peculiar form were taken on the island. It is quite variable in the proportion and distribution of the green colour upon the upper surface, and especially on the wing-covers. Specimens of one or other of its several varieties have been sent to m e from Cuba, Florida, Eastern North Carolina, Central Illinois, and Para, Brazil. I have also found it myself on plants in low grounds in Eastern Virginia, N e w Jersey, and on both shores of Chesapeake Bay, Maryland, in July and August. DELTOCEPHALUS EETEOESUS, sp. nov. Fuscous or blackish, more parallel-sided thau the preceding species. Head short, obtusely triangular ; vertex depressed at base, tumidly elevated at tip, pale brownish yellow, with a slender black stripe on the middle at base: an indented black spot each side behind next the eye, an interrupted band across the middle and a narrower one next the tip also black, the middle and interval between these bands and the very tip pale green ; front convex, black, minutely rough, with about three series of pale |
