120 HTMENOPTERA. 



cence, the femora with a longish white hair ; the anterior knees are only slightly marked 

 with white, the four posterior hroadly at the base of the tibiae and the apex of the 

 femora ; the base of four posterior coxae black. The antennae are pilose, subclavate, thick, 

 not much longer than the abdomen ; the scape is compressed on the lower side, broad, 

 rounded at either end, the side double the width of the back ; the scape at the top 

 testaceous, as is also the apex of the fifth arid sixth to the eighth joints ; the third joint 

 is scarcely one half of the length of the fourth, which is about one half longer than the 

 fifth ; the latter is not much longer than the sixth, and is thinner than it ; the seventh to 

 the ninth are not much longer than broad, the club shorter than the three preceding, 

 compressed at the sides. The base of the wings is mostly hyaline, and in the middle of 

 this clear portion is a somewhat square mark touching the ulna ; at the end of the 

 ulna is a larger fuscous mark, broad above, narrowed below ; in front of the cubitus is 

 a broad, triangular (looked at from the apex of the wing) cloud, which stretches from 

 one side of the wing to the other, its sharp end pointing to the base of the wing, and 

 almost running into the hyaline space at the base ; the nervures are bright testaceous, 

 except where touched by the fuscous portions of the wings. 



7. Eupelmus albispina. 



Niger, pilosus, subnitidus; tarsis terebraque testaceis; pedibus posterioribus basi, tibiarum posticis dimidio 



basali calcaribusque albis ; alis fumatis, albo maculatis. 

 Long. 4-5 millim., terebra 1 millim. 



Hab. Panama, Bugaba 800 to 1500 feet (Champion). 



Head minutely punctured, the thorax alutaceous, except the pleurae ; abdomen 

 smooth, shining, and with a steel-blue tint. The middle spurs are as long as half the 

 metatarsus ; the posterior tarsi are testaceous only at the base. The base of the fore 

 wings is almost hyaline, and in front of the cubitus is an oblique narrow hyaline stripe. 



8. Eupelmus bimaculatus. 



Hab. Panama, Bugaba (Champion). 



Similar to E. petiolaris in the coloration of the body and legs, but differing from 

 that species in the following points : — The antennal grooves are deeper, and their outer 

 margin is more distinctly keeled, being separated from the eyes by a slight groove ; 

 the mesothorax, instead of being almost flat, rises sharply to a peak to the base of the 

 scutellum, which has an almost perpendicular slope. The abdomen broadens out con- 

 tinuously from the base, which does not form a neck. The basal joint of the middle 

 tarsus is thinner, and the long spur is as long as it, and quite black ; not shorter than 

 it, and testaceous, as in E. petiolaris. The base of the flagellum is testaceous (but of a 

 darker shade than the scape), while in E. petiolaris it is only piceous.
