DI9IICROSTROPHIS n. g. 



This genus differs from Eucoila West., and Hexaplasta Foerst., in 

 having the fourth and fifth antennal joints in 9 very small, the six 

 about as long as third, but stouter, and joints seventh to thirteenth 

 enlarged, moniliform, slightly peduncled and striate. The wings are 

 ciliate, and the pubescent abdominal girdle is nearly obsolete. In 

 the male the third joint of antennae is longest, narrowed at base, and 

 the following joints are about thrice as long as wide, the terminal 

 joints being a little longer than the preceding one.
