trochanters, the tibiae, except at tips, and the tarsi honey-yellow ; 

 the flagellum is covered with a whitish pile ; the first and second 

 joints are twice as long as thick, about equal, a little longer than 

 the pedicel; third joint short, triangular; club 5-jointed, the 

 joints oval, the last conical, longer than the penultimate. 



Sab. St. Vincent. 



Described from one male and one female. This species comes 

 quite close to I. Lintnerii, Ashna., described from the District of 

 Columbia. 



AcEROTA, Worster. 



ACEEOTA CO]STUSA, Sp. n. 



S $ . Length 1 to l"! millim. Subrobust, polished black ; 

 the head closely, microscopically punctate ; antennae and legs 

 yellowish ; scape at the middle, club, and the swollen part of 

 the tibiae fuscous or brown, the coxae black ; the pedicel is 

 longer than the first f unicle-j oiut ; the second funicle-joint 

 slightly longer than half the length of the first ; the third and 

 fourth transverse ; club joints subquadrate. The thorax is 

 polished, but faintly punctate and with two distinct furrows. 

 Scutellum convex, finely punctate, and bounded by a carina 

 behind. Metapleura subsericeous. Wings hyaline. Abdomen 

 oblong-oval ; in female subacute at tip, polished, with the first 

 segment striate. 



The antennae in the male are wholly black, covered with a

 long conical last joint, not longer than wide, slightly pedicellated ;

Sah. St. Vincent. 



Described from one male and one female. The male of this 

 species could easily be mistaken for a male Inostemma. 



Ambltaspis, Fdrster. 

 The species I take to belong to this genus may be tabulated 

 as follows : — 



Scutellum triangular, pubescent A. triangularis, sp. n. 



Scutellum produced into a long spine that projects 

 high over the metathorax. 



Coxae pale 2.
