NEOBROTICA AND RELATED GENERA — BLAKE 331 



Hystiopsis bryanti, new species 



Figure 72 



About 6 mm. in length, elongate oblong oval, shining, the elytra 

 with many flat costae, the interstices being geminate striate punctate, 

 yellow brown with the occiput of the head piceous, a brown lateral 

 vitta interrupted before the apex on the elytra, and a brown area 

 about scutellum. 



Head with the interocular space half width of head, frontal tubercles 

 swollen but not very definitely marked, a median depression above 

 them, carina a thin line down front, lower front depressed, punctate, 

 tan colored, the occiput and mouthparts piceous. Antennae brownish 

 with the three basal and three apical joints paler. Pro thorax almost 

 rectangular, the sides slightly curved, a shallow transverse sulcus, 

 shiny, impunctate, yellowish brown. Scutellum yellowish brown. 

 Elytra shining and with many low costae, the intervals being ir- 

 regularly and rather coarsely geminate-striately punctate, yellowish 

 brown with deeper brown lateral markings and a narrow brown area 

 surrounding the scutellum. Body beneath and legs pale, the breast 

 piceous, middle and hind tibiae with a spine. Length 6 mm.; width 

 3 mm. 



Type, female, BMNH, from Trinidad, collected by G. E. Bryant, 

 March 1903. 



Remarks: Only one specimen, a female, is known. The coloration 

 is unlike any of the other species. It is less strongly costate than 

 most of the group, but the costae are still apparent. It differs from 

 H. marginalis (Fabricius) in having a dark instead of pale occiput 

 and not so long antennae. 



Hystiopsis mapirii, new species 



Figure 85 



About 5 mm. in length, oblong oval, somewhat shiny although 

 alutaceous, the elytra strongly costate; pale yellow, the head piceous 

 down to antennal sockets, elytra with a short reddish brown vitta 

 along the side below the humerus and a spot at the apical curve, suture 

 about scutellum and below faintly reddish brown and another faint 

 darkening near the apex, breast brown, tibiae and tarsi brownish. 



Head with the interocular space approximately half width of head, 

 occiput finely punctate, frontal tubercles not clearly marked but 

 swoUen and with a median depression above ; lower front depressed and 

 without any trace of carina, the top of head down to antennal sockets 

 shining piceous, lower front pale yellow with the mouthparts tipped 

 with brown. Antennae pale, except the dark tip of the terminal joint. 

 Prothorax not twice as broad as long with somewhat curved sides and 

 a transverse depression; surface alutaceous, finely punctate and en-
