4. iENICTUS PUBESCENS. 



Length 3^ lines. — Rufo-testaceous, densely clothed with pale 

 pubescence : the head black and shining ; the mandibles and

 and curved. The thorax obscure ferruginous ; wings hyaline 

 and iridescent, the nervures and stigma dark brown. Abdomen

 slightly rounded at the sides, the peduncle of the same width as 

 the second segment, the terminal segment obtuse.

This species closely resembles JEnictus ambiguus, from which 

 it differs in being covered with dense long pale silky pubescence ; 

 the anterior margin of the prothorax is much more obtuse, and 

 is notched in the middle; the peduncle is of a different form, 

 for which refer to Plate II. fig. 17-

In this Catalogue the Thynnidcs are divided generically on 

 the differences of neuration in the anterior wings. After a careful 

 examination of several extensive collections of Thynnidce, that 

 in particular of the British Museum, we find that the palpi 

 differ in the number of joints in the males and females of the
