tbe two, and comes, in fact, in several points so near Dolbina that the discovery of 

 a form connecting the two genera woukl be no surprise to us. Dolhina has nothing 

 to do with the American Dolha ; the similarity is quite superficial. 



Staudinger says. I.e., that the hindtibiae have only one pair of s[)urs ; in this 

 he was wrong.

S ? . Antennae of both sexes with fasciculated ciliae on all segments, the ciliae 

 on the terminal segments long in <? ; segments rounded-dilated dorso-laterally in 

 S and ?, especially the middle ones ; end-segments see PI. LX. f. 10. Pilifer 

 with a brush of scales and a few bristles. I'alpus rongh with hairs, especially the 

 first segment. 



S . Tenth abdominal tergite triangular, about twice as long as broad l)asnl]y, 

 pointed, flat above, curved downward, prismatically compressed distally, the 

 underside carinate (PI. XXVIII. f 22) ; sternite broad, short, truncate-sinuate, 

 angles rounded. Dorso-distal margin of clas])er very oblique; harpe (PL XXXIX. 

 f 21) with a broad, almost flat, nj)per lobe, which is dentate and sinuate, the 

 ventro-distal process slender, cylindrical, obtuse. Penis-funnel cylindrical, somewhat 

 obliquely truncate ; peuis-slieath ending in a long, slender, pointed hook curving 

 proximad and sinistrad (PI. XXIX. f. 32). 



?. Vaginal plate feebly sinuate ; tlie wide vaginal cavity covered proximally 

 by a broad rounded lobe (PI. XXI. f 21).
