NO. 1202. GENERA OF THE ENCYBTINJE—ASHMEAD. 371 



2. .^NASIUS CHAPAD^ Ashmead, new species. 



Female. — Length, 1 mm. Robust, short and broad, very little longer 

 than wide. Head blue, thorax above blue-black, beneath aeneous black; 

 abdomen metallic aeneous; scape within and at tip, and the funicle pale 

 brown, rest of scape and the club brown-black; legs dark brown, the 

 tarsi light brown or yellowish; wings subfuscoos. 



The head is covered with a close, thimble-like punctuation, clear to 

 the scrobes, which are short; the eyes are large, long-oval, and pubes- 

 cent; the scape has the characteristic leaf-like expansion beneath; the 

 funicle is short, the joints, except possibly the first, which is small arid 

 moniliform, are wider than long and increase in width to the club, the 

 latter being very large and as long as the funicle and very much 

 thicker. The thorax is similar to that in A. hyettus Walker, except 

 that mesonotum has the thimble-like punctuation similar to that of the 

 head, only less distinctly impressed; the scutelUim is large, about twice 

 as long as the mesonotum, with the punctuation almost obsolete.
