[Hemiptera Heteroptera.] 

 (PLATE IV.) 



By OTTO HEIDEMANN. 



Acysta perseae, n. sp. 



Colors sharply contrasting, shining black and yellowish white. Head 

 short, closely set into thorax, black except the two small, converging 

 spines in front and the narrow bucculae on the underside, which are 

 yellowish white; surface between eyes convex and somewhat rugulose, 

 a little impression at base near them; antenniferous tubercles blunt 

 but prominent. Eyes dark brown, strongly facetted. Antennae slender, 

 somewhat longer than distance from front of head to apex of posterior 

 portion of pronotum; basal joint not much longer than second, both only 

 slightly thicker than third; fourth joint dusky towards tip. Rostrum 

 yellowish, nearly reaching meso-metasternal suture. Thorax black 

 and shining, strongly punctured, moderately convex, transversely im- 

 pressed near front, thence the sides narrowing abruptly towards an- 

 terior margin, the latter with a narrow yellowish rim ; pronotum 

 without a hood and with only one median carina; membranous lateral 

 margins of thorax nearly obliterated, visible only as two very small 

 ear-like expansions near shoulders, translucent, yellowish white, bear- 

 ing a few minute round cells; tip of posterior portion of pronotum 

 of same color and closely reticulated. Elytra oblong-oval, much longer 

 than abdomen, somewhat narrowing towards apex, rounded at tip, 

 translucent, yellowish white, with a transverse black vitta near the 

 middle which becomes broadest at the discoidal areas, and beyond the 

 latter a few nervures inf uscated ; discoidal area apparently not closed 

 posteriorly by a raised nervure, barely wider than the subcostal area, 

 both closely reticulated with very small areoles ; costal margin about 

 as broad as the discoidal area, with rows of three or four areoles at 

 its widest part, these areoles increasing a little in size towards apex 

 of elytra. Wings attaining tip of abdomen, highly iridescent. Body 

 black, shining, sparingly pubescent. Rostral groove uninterrupted, the 

 marginal laminae not strongly raised, yellowish; metasternum black, 

 highly shining, transverse, flat. Last abdominal segment in the female 

 broadly rounded at apex; in the male, oblong, a small round fovea on 

 sides and strongly curved claspers at tip. Legs yellowish white, except 

 the claws, which are blackish. Length, 2 mm. ; width, 0.8 mm. 



Described from two specimens, male and female. In ad- 

 dition I have examined some others, and a few larval forms.
