sensorial papillae and 3 hairs, the median one of which is 

 longer than the whole antenna?, and curved in the distal l /sJ 

 the 3rd joint is bifurcate and comparatively more developed 

 than in many other external feeders [comp. Dampf 14.]; one 

 of the lobes has a conical, sensorial papilla, the other a 

 straight bristle and between both is a small hair.

In Tischeria we find nearly the same type (fig. 20); but

In Eriocrania (fig. 21) we also find 3 distinct articles, and 

 the 2nd of these has a very stout and straight bristle exter-
