EUPELMUS. 115 



EUPELMUS. 



Eupelmus, Dalman, Kongl. Vet. Acad. Handl. ii. p. 378 (1820). 



In having the front ridged near the insertion of the antennae the species I have 

 included here do not agree with one of the principal characters given by Foerster 

 (Hymen. Stud. ii. p. 31) to define Eupelmus, and none of them have the second abdo- 

 minal segment incised. They, however, agree tolerably well with Eupelmus generally. 

 The species are mostly black, more or less tinted with metallic green ; the wings dark 

 with hyaline fasciae. It is difficult to count the number of joints in the antennae, so 

 closely are they united together; but the majority would appear to have them eleven- 

 jointed. Possibly there may be three joints in the club. 



I have divided the genus into sections, which may hereafter be raised into genera. 



I. Antennae with the scape strongly compressed laterally, with a knife-like edge on the 

 lower side, where it is much thinner than on the back. Antennal grooves short, 

 broad. Ocelli not touching the groove. Flagellum thick, compressed, densely 

 pilose, first joint a little longer than the next, the others subegual; there are eleven 

 joints in all. Thorax raised into a sharp ridge on the back. Ovipositor scarcely 

 projecting. Abdomen somewhat depressed in the centre above, longer than the 

 head and thorax together. 



l. Eupelmus compressicornis. (Tab. VI. fig. 12, ? .) 



Nigro-viridis, pilosus ; antennis nigris ; pedibus testaceis fusco maculatis ; alia subfumatis. 

 Long. 4 miltim. 



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



The antennae are shorter than the thorax and abdomen, thick, compressed, covered 

 with a close pile, and they taper in thickness towards the apex; the joints (except 

 the first of the flagellum) are broader than long ; the first of the flagellum is a little 

 longer than the succeeding, and is narrower at the base than at the apex. The head 

 is punctured, and covered with a short pale pubescence. The thorax is uniformly 

 alutaceous, almost punctured. The abdomen, except at the apex, is smooth, shining, 

 impunctate ; the apex is covered with shallow punctures. The spur on the middle leg 

 is two thirds of the length of the basal joint of the tarsus. The head is green, some* 

 what coppery on the front ; thorax dull black ; apex of the abdomen green, the rest 

 bluish black ; the wing-nervures are yellowish testaceous ; the femora, tibiae, and tarsi 

 -jare suffused with fuscous.
