STKONGYLOGASTEK. 7 



in the first transverse cubital nervure ; the transverse median nervure is. received a little 

 in front of the middle of the cellule. The sutures on vertex are narrow, but deep ; the 

 frontal area clearly defined above, less so on lower side. The central fovea is very large, 

 the lateral longer and deeper, but less clearly defined. 



A shorter, broader insect than S. v-Jlavum, the antennae shorter and thicker, the 

 third joint shorter compared with the fourth ; the cubital cell is shorter, the wings 

 clearer, &c. In S. Icetus, behind the eyes, there is thick fulvous hair, which becomes 

 black on the vertex ; the central antennal fovea is much more clearly defined than in 

 S. v-flavum, but not the lateral ones.

7. Strongylogaster testaceicornis. 



Niger, antennis (apice excepto), ore, tegulis, linea tenui marginali pronoti, maeulis pleuralibus, scutello, abdo- 

 minisque basi testaceis ; pedibus pallide testaceis, coxis basi, femoribus tibiarumque posticarum apice 

 nigris ; alis flavescentibus, costa et stigmate testaceis. 



Long. 9 millim. 



Hal. Costa Eica, Irazu 6000 to 7000 feet {Rogers). 



Vertex faintly punctured, covered with a fulvous pile ; frontal and antennal foveae 

 and sutures indistinct. The antennae are shorter than the abdomen, thickened in the 

 middle ; the last joint considerably thinner than the eighth, the third longer than 

 fourth. Clypeus slightly incised at the apex. On the mesopleura there is towards the 

 hinder end a broad, obscure, testaceous spot; below it is an oblique thinner one 

 following the division of the mesopleura ; and there is a smaller one on the metapleura. 

 The blotch is large and broad ; the three basal segments are entirely testaceous at the 

 sides and beneath ; and at the apex of the second and third segments above, the 

 testaceous colour forms two distinct bands. The transverse radial nervure is almost 

 interstitial; the second and third cubital cellules are almost equal in length; the 

 transverse median nervure is received close to middle of the cellule. Claws simple. 



The male has the antennae black above throughout, the middle joints are dark 

 testaceous ; the costa and stigma are dark testaceous ; the basal segment of abdomen 

 is broadly testaceous above ; and the posterior tibiae fuscous, except the basal third. 



A much narrower and somewhat longer insect than 8. Icetus, with the vertex punc- 

 tured, frontal area more clearly defined, face shorter, and thorax slightly punctured 

 and more pilose.
