 GOO /x long, with subapical bristles; maxillary comb well developed, 

 but the teeth rather short and blunt; maxillary stipes about 1,275 /.-.

 Avas lost in the single preparation I was able to make.

 sparsely punctured, but the hind margin delicately fluted; meso- 

 thorax rather sparsely but strongly punctured, with distinct median

 stigma large; marginal cell narroAvly subtruncate, appendiculate; 

 tAvo submarginal cells, the second at least as long as the first below,

 recurrent nervures, the first fully tAAMce as far from its base as the 

 second from its end ; transA^ersomedial nervure very oblique ; abdomen 

 dull, the broad hind margins of the segments more shiny, and pale 

 golden-hyaline; segments Iavo to four A'ery sparsely fringed AA^th

''111 Hcspcrapis (II. rhodocrrata Cockerell) tlio maxillary palpi are really 

 A-ery different, in that the first joint is much shorter than the second, and the 

 joints are more narrowed basally. The stipes is also very much shorter in i)ro- 

 portion. The maxilhu-y paljii of Perditomorpha an? nearly the same as those 

 of Ifi/imiiiiiri-otcrd (Cockorell and Porter, Ann. Mag. Nat. Hist, Dec, ISDU,
