78 PEOr. p. H. UHLEE ETiTFMERATION OP THE [Jau. 15, 



Length to end of venter 3| mm., to tip of wing-covers 5 mm. ; 

 width of pronotum 1 mm. 



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 vino dlatus, sp. nov. 



Form short, robust ; head bluntly subconical, black, striped with 

 green, polished ; the wing-covers coriaceous throughout, wide at 

 tip aud bluntly rounded. Head of about the same length as pro- 

 notum, 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 elypeus 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. iScutellum dull black, transversely incised, pale 

 at tip. Legs black, the posterior tibiae with pale spines, and the 

 tarsi more or less pale. Pleural segments more or less mai-ked 

 with pale green. Wing-covers thick, coarsely scabrous, and obso- 

 letely punctate, so broadly marked with green as to give predomi- 

 nance 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| mm. ; 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 me from Cuba, Ploinda, Eastern North Carolina, 

 Central Illinois, aud Para, Brazil. I have also found it myself ou 

 plants in low grounds in Eastern Virginia, New Jersey, and on 

 both shores of Chesapeake Bay, Maryland, in July and August. 



Deltocephalus eeteorsus, sp. nov. 



Euscous or blackish, more parallel-sided than the preceding 

 species. Head short, obtusely triangular ; vertex depressed at base, 

 tumidly elevated at tip, pale brownish yellow, Mith 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 gi-een ; front 

 convex, black, minutely rough, with about three series of pale
