of the submarginal, or less tlian twice the length of the stigmal, 

 the latter clavate ; postmarginal very slightly shorter than the 

 marginal. Abdomen pointed ovate, longer than the head and 

 thorax combined, subsessile, metallic green; the first body-segment 

 the longest, as long as segments 2, 3, and 4 combined, with a 

 large fovea at base surrounding the very short petiole ; segments 

 5 and 6 subequal, longer than the 4th. 



c? . Length 2 millim. Differs from female only in its ovate 

 abdomen, with the venter and spot on dorsum white. 



Hob. St, Vincent. 



Described from one male and one female. 



Catolaccus vtjlgaeis, sp. n. 



S 2 • Length 1 to 3*1 millim. In colour variable from a 

 bronze-green to blue-green or seneous ; head and thorax con- 

 fluently punctate, with short, sparse, white hairs ; scape and 

 legs honey-yeUow or brownish yellow, often whitish, but with 

 the coxae and femora, except at tips, always metallic, bronze, or 

 seneous. Funicle 6-jointed, filiform, the first joint a little the 

 longest, the last longer than wide; club slightly stouter, 3- 

 jointed. Thorax as in the preceding species, only the parapsidal 

 furrows are only distinct for half the length of the- mesonotum 

 anteriorly, and the scutellum is without the transverse impressed 

 line before its apex. Wings hyaline, the tegulse and venation 

 yellowish ; marginal vein two thirds the length of the submar- 

 ginal, or about two and a half times as long as the stigmal, the 

 postmarginal about two thirds the length of the marginal. 

 Abdomen pointed, ovate, subsessile, from one third to one half 

 the length of the head and thorax united. 



The male difiers from the female decidedly in its antennal and 

 abdominal characters. The antennae are subfiliform, pubescent, 

 the flagellum much stouter than the scape and pedicel, the f unicle- 

 joints very gradually subequal, almost twice as long as thick, the 

 first joint being twice as long as the pedicel ; abdomen ovate, not 

 quite as long as the thorax, the basal half, except at junction 

 with the metathorax, white, or at least with a large white blotch 

 both above and beneath, the segments being about equal in 

 length. 



Hah. St. Vincent. 



A common species variable in colour and size ; described from 

 many specimens.
