the two, and comes, iu fact, in several points so near Dolbina tliat the discovery of 

 a form connecting the two genera would be no surprise to us. Dolbina has nothing 

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



Staudinger says, I.e., that the hindtibiae have only one pair of spurs : in this 

 he was wrong. 



Key to the species : 



a. Antenna with large brown ])atch on the 



upperside ........ b. i 



Antenna with the patch absent or only 



vestigial ....... 133. K. sieversi. 



b. The two antemediau lines of the forewing 



ending at inner margin iu a black patch. 132. K. consimilis. 

 The two antemedian lines less distinct, the 



black patch absent . . . . .131. K. stnic/ieri.

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

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

 (? and ?, especially the middle on(^s : end-segments see PL LX. f. 10. Pilifer 

 with a brush of scales and a few bristles. Palpus rough with hairs, especially the 

 tirst segment. 



i. Tenth abdominal tergite triangular, about twice as long as broad basally, 

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

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

 angles rounded. Dorso-distal margin of clasper very oblique; harpe (PL XXXIX. 

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

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

 obliquely truncate ; penis-sheath ending in a long, slender, pointed hook curving

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

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