ON SOME NEW CHINESE FLEAS. 



comb is about the same as tlie distance from this spine to the 

 last spine of the comb, whereas in the new species the former 

 distance is less than half the latter.

Head. — The genal process, which is visible above the la.ot spine 

 (text-fig. 123), is much broader than in trijjectinaia, and the 

 rostrum is longer than in that species. The second segment of 

 the antenna has two rows of bristles in both species. The genal 

 comb consists of nine spines. 



Thorax. — The thorax is similar to that of tripectinata. 



The pronotal comb consists of 35 spines. 



Abdomen. — The tergites have only two rows of bristles each, 

 only segments I, II, and III having an incomplete third row, 

 while in tripectinata all the tergites have 3 or 4 rows. There are 

 4 antepygidial bi'istles on each side. The comb of the first 

 tergite contains 31 spines on the two sides together. 



Legs. — The bristles of the legs are shorter, especially those of 

 the hind taxsus, and also not so thin at the tip. The longest 

 apical bristle of the first hind-tarsal segment reaches only to tie 

 subapical notch of the second segment, and the longest bristle of 

 the second segment scai-cely extends to the apex of the third. 



Modified segments. — $ . As these segments are represented 

 by text fig. 124, we need only point out some characters in 

 which they diflfer from the segments of tripectinata. The lobe
