EUPELMUS. 123 



ceous, and covered with short, white, depressed hairs, except on the posterior part of 

 the mesopleurae. The face is closely covered with white hairs ; scutellum with a few long 

 white hairs ; and there are a few long hairs along the edge of the mesonotum. The 

 apical abdominal segments are covered with long white hairs along the edges of the 

 segments, beneath with black hairs. The legs are covered with a white pubescence. 

 The mesonotum is margined along its whole extent, and with a V-shaped furrow ; but 

 there is no transverse furrow in front of the scutellum, which is depressed. The wings 

 are subhyaline at base and apex ; and there is a white band in front of the cubitus ; 

 this band does not stretch across the wings, and is broadest in front. The head, thorax 

 (especially the metathorax), and base of abdomen have a steel-blue reflection. 



14. Eupelmus petiolaris. 



Hab. Guatemala, Pantaleon 1700 feet (Champion). 



In general coloration this species agrees with E. cingulatus, but it is slightly shorter 

 and narrower. The thorax is more shining, less alutaceous. The second abdominal 

 segment is longer, narrower, double as long as broad, and distinctly separated from the 

 rest of the abdomen by its narrowness, the apical part bulging out abruptly from it ; it 

 is entirely white, except a narrow black band in its middle. The apical portion of the 

 abdomen is more shining than in E. cingulatus. The wings are not hyaline at the apex, 

 and at the cubitus there are two white fasciae, one on either side of the wing, that close 

 to the cubitus itself being the largest. The knees, anterior tarsi, and lower side of 

 the hind femora are obscure testaceous. 



15. Eupelmus fasciiventris. 



Niger ; scapo antennarum, abdominis apice, terebra tarsisque rufo-testaeeis ; apiee coxarum, abdominis basi 



subtus efc femoribus posterioribus subtus albis ; alis fumatis, albo fasciatis. 

 Long. 6 millim. 



Hab. Panama, Bugaba (Champion). 



Scape of antennae longish, curved ; flagellum becoming thickened gradually towards 

 the apex ; first joint (the ring) double as long as broad, second about one fourth longer 

 than the third ; all the joints covered with a close white pile. Head opaque, for the 

 most part covered with a matted pubescence, punctured finely. Antennal grooves broad, 

 comparatively shallow, not reaching to the ocelli. 



Closely related to E. cingulatus, but the white on the second abdominal segment is 

 only on the sides and beneath ; the abdomen is longer compared to the thorax ; the 

 last segment longer, not so hairy, and more distinctly punctured ; ovipositor longer, its 

 sheath testaceous ; the white band at the cubitus is, if any thing, narrower, whiter, and 

 more clearly defined. The four posterior trochanters are white, as are also the base of 

 the femora, which are more or less obscure testaceous on the lower side. The antenna?
