OF THE ISLA.ND OF ST. VrtfCENT. 105 



length of tlie sclerite, and two short ones to the outside ; post- 

 scutellum only yellow ; tegulae metallic at base ; all legs yellowish, 

 except metallic base of hind coxae ; first and last two joints of 

 abdomen metallic, the others reddish yellow ; wing- veins dark, 

 stigmal very distinct. 



S . Length 1'5 millim. ; expanse 3*1 millim. ; greatest width 

 of fore wing 0*37 millim. Differs from female, beyond the ordinary 

 sexual characters, only in having second joint of abdomen reddish 

 yellow, and all cosaa and femora metallic, except at tips. 



. Described from two females and three males. The males may 

 not belong to this species, and indeed in some respects resemble 

 more the following species — U. pimctatus — than the females with 

 which I have associated them. The balance of characters, how- 

 ever, places them here rather than with any of the other species 

 in the St. Yincent collection.

 of fore wing 4'9 millim. Differs from E. levifrons as follows : — 

 Head and face punctured as in E. maculatus ; middle tibial spur 

 more than one third as long as first tarsal joint ; dark lines on 

 hind tibia forming two narrow, wavy, longitudinal cells, side by 

 side, and each extending the whole length of the sclerite, just as 

 in E.flavus. Head, entire trunk, and all coxae and femora uniform 

 dark metallic greenish-blue. Wing-veins dark, disk very slightly 

 infuscated. In two of the five specimens the front femora are

Euplectrus furaius, Walker, Ann. Mag. Nat. Hist. xii. p. 48 ( =bicoloiv 

 Swed.). St. Vincent. 



Eepresented by three males and one female. 



"Walker suspected the identity of this species with E. hicolor 

 (Swedevus) =ElacJiistus alUventris, 8^mo\si,= Euplectrus onaculi- 

 ventris, Westwood ; but a careful comparison of Thomson's 

 description of E. hicolor with Walker's of E. furnius indicates 

 that they differ in mesonotal characters.
