EUPELMUS. 117 



III. Scape of antennas cylindrical, flagellum becoming gradually thicker from the base 

 towards the apex. Antennal grooves reaching close to the ocelli, but very shallow 

 on upper half. Pronotum triangular above, flat, with a deep groove in the middle. 

 Mesonotum flat or ridged. Abdomen convex above and beneath, the sides a little 

 compressed. Ovipositor retracted. Wings abbreviated. Body testaceous. 



3. Eupelmus testaceilS. (Tab. VI. fig. 10, $ ; 10 a, antenna.) 



Rufb-testaceus ; apice antennarum nigro, abdominis basi alba, capite cupreo variegato ; alis fusco-brunneis, 



albo fasciatis. 

 Long. 6-7 millim. 



Hab. Panama, Volcan de Chiriqui 3000 to 4000 feet (Champion). 



Antennae almost bare, and becoming thickened towards the apex ; the third and fourth 

 joints subequal. Head finely and closely rugose, rust-coloured, except in the centre, 

 which is blackish. The mouth-region is greenish black. Eyes chocolate. Head 

 sparsely pilose. Thorax smooth, shining, and covered with a black pubescence. The 

 prothorax above is longer than broad, obsoletely punctured, and with a longitudinal 

 furrow in the centre of the pronotum, which is flat. The mesonotum is light testaceous, 

 impunctate ; the scutellum and metanotum reddish testaceous and minutely punctured, 

 especially the metanotum, which is flat, and bears a well-marked keel in the centre. 

 Pleurae finely punctured, black along the edges, reddish testaceous for the rest. Abdo- 

 men a little longer than the thorax; the basal third smooth, shining, the rest finely 

 punctured ; the greater part of the second segment is white. The wings are scarcely 

 longer than the thorax ; they are brownish ; in front of the middle is a white band, 

 which extends right across ; there is a small white mark (longer than broad) at the 

 cubitus close to the costa ; these white parts are surrounded with a fuscous border, and 

 the apex of the wing is also fuscous. 



4. Eupelmus brevipenuis. 



Bufo-testaceus ; capite cupreo, antennarum apice, abdominis basi, coxis femoribusque nigro-maculatis ; alis 



fumatis, basi hyalinis. 

 Long. 4| millim. 



Hab. Panama, Volcan de Chiriqui 3000 to 4000 feet (Champion). 



The head is coppery, as in E. testaceus, and otherwise agrees with that of the latter, 

 but the antennae are somewhat shorter. In the form of the prothorax the only difference 

 is that in E. brevipennis it is quite flat, this being also the case with the mesonotum. 

 The metanotum is shorter, and there is no distinct central keel. The abdomen is shorter 

 than the thorax. Thorax very finely punctured. Abdomen smooth, shining. The four 

 posterior coxae are largely marked with black ; the posterior femora are broadly lined 

 with the same colour above ; the base of the abdomen is longer, black ; and there is an 

 obscure white ring on the second segment. The wings are narrow, shorter than the 

 mesothorax ; the basal half is hyaline, the apical brownish.
