 Worker. Length 3 lines. Black and shining ; the head oblong, sides 

 nearly parallel ; the eyes very large, ovate, extending to the posterior 

 angles of the head ; the anterior portion of the clypeus, the mandibles, 

 scape, tibise, tarsi, and tips of the femora pale ferruginous. Thorax 

 compressed behind; the prothorax above, the first segment of the 

 abdomen and the basal margin of the second pale yellow ; the scale 

 of the peduncle oblong, slightly rounded above. (PL IV. fig. 3, ^ .) 

 Hab. New Guinea. 



This remartable Ant, of which a figure is given, will probably 

 constitute the type of a new genus. The greatly ealarged eyes, 

 placed backwards on the head, give it a diiferent aspect from any 

 species previously described. Unfortunately the only specimen 

 received is in such a mutilated condition that I could not examine 

 the parts of the mouth. Should an examination of more specimens 

 prove my conjecture to be correct, I would propose the name 

 Myrmecopsis for the genus.
