2. TETRALOPHIDEA Ashmead, new genus. 

 (Type, TetralopMdea hakeri Ashmead.) 



This genus comes nearest to Galocerinus Howard, but the head is not 

 quite so large nor so broad i)roportionately; the lateral ocelli are more 

 distant from the eye margin, being about three times as far from the 

 eye margin as their diameter; the pronotum is shorter; the mesonotum 

 and scutellum are less convex; the wings are clear hyaline, not fuscous 

 with white bands, as in Calocerimis; while the abdomen is proportion- 

 ately longer. 



The genus is readily separated from Calocerimis, the only one with 

 which it shows any affinity, by the hyaline wings and the position of the 

 ocelli,

Male. — Length, 1.5 to nearly 2 ram. Head and thorax aeneous black, 

 the meso pleura blue; mandibles dark rufous or ferruginous, bidentate;
