TRICHURA. 113 



SUB-FAMILY VIII. TRICHURIN^E. 



Dr. Butler distinguishes this Sub-family (which he calls 

 Eunomiincz) from the last by the median nervure of the hind- 

 wings having more than two branches, one of which is always 

 emitted before the end of the discoidal cell. The Moths which 

 it includes are all American, and are of smaller average size 

 than the Euchromiince, and generally have transparent wings. 

 Some of them are provided with a very remarkable appendage 

 at the extremity of the abdomen in the males. The antennae 

 are pectinated, and the abdomen is sometimes contracted or 

 petiolated at the base, increasing the resemblance to the 

 Hymenoptera, which so many of the transparent-winged Zygte- 

 nidce exhibit. The Trichurincz are not a very extensive Sub- 

 family. The more opaque species are generally larger and 

 more brightly coloured than the others, and in these the abdo- 

 men is often tufted at the extremity.

These are slender-bodied Moths, with pectinated antennae 

 and transparent, dark-bordered wings. The legs are slender, 

 and the wings are transparent with black borders. The abdo- 

 men is contracted at the base, and is furnished with a long 

 hairy appendage in the males.
