 Antennae .11 mm. in length, six-segmented, the segments very distinct, with 

 strong constrictions between them, and each with a few prominent hairs; 

 first segment stout, second smaller and shortest, about one-half the length of 

 first, third a little longer than first, fourth shorter than third but longer than 

 second, fifth slightly shorter than third, sixth as long as third, — formula

 tapering, and without claw. 



Adult 7I/a/<?. — Length about 1.4 mm", breadth .4 mm.; general color pink,
