the. iiHierside one. There is one regular row of long slender bristles nn tlie onter- 

 side of the tibiae. The hindtibia bears at tlie dorsal edge nine bristles of nearly 

 the same length, the second, sixth, and eighth being [jaired with a long bristle on 

 the innerside of the dorsal edge. The second long bristle (standing at the apical 

 third) is longer than the subapical one, and more than twice as long as the tibia 

 is broad. The tarsi are slender, and their bristles are nnmerons. The first hind- 

 tarsal segment is one-fourth shorter than the hindtibia, being as long as the second 

 and third segments together. There is one stout spine at the apex of the tarsal 

 segments, the longer of the second segment not reaching to the apex of the 

 third. There are four bristles on each side of the fifth segment, besides a subajiical 

 hair. The measurements of the tarsi are as follows :— 



Modified Segments.— The eighth tergite of the S is small, while the sternite is 

 large, bearing ventrally two bristles on each side. The ninth sternite is slender, 

 slightly curved, and provided with a few hairs at the apex {VI. XV. fig. 87). The 

 clasper is long (PI. XV. fig. 87, CI.). It bears two bristles at the upper edge and 

 a longer one at the apex. The finger (f) is triangular, hardly projecting beyond 

 the clasper. The tenth tergite bears scarcely any hairs, except a long one standing 

 just behind the sensory jilate. 



The eighth tergite of the ? (PI. XVI. fig. 91) has no hairs above the stigma. 

 There is one long bristle below the stigma and a number of others farther down, 

 as shown in the figure. The eighth sternite is small. The stylet is cylindrical, 

 being about four times as long as basally liroitd, ei|niilling the first midfarsal 

 segment in length.

We have three examples of this sjiecies, collected by Mr. (1. J. P.. Grant, as

The present species and the following one are placed in the genus Cteiiopsiillua 

 in spite of the presence of a well-developed eye, as these insects agree fairly well 

 with C muscuU and C. pectiniceps. The position of the eye near the upper end 

 of the antennal groove and the position of the genal spines halfway between the 

 eye and the frontal edge of the head is peculiar to the two new species described 

 here. The position of tlie comb of genal spines is suggestive of the anterior comb 

 found in Step/ianocirci/s. 



35. Ctenopsyllus aganippes spec. nov. (PL XV. fig. 83; XVI. fig. !mi). 



Head. — The front of the head (PI. XV. lig. 83) is much longer than in C.granti. 

 The comb consists of ten spines which gradually become longer from the top one to 

 the eighth and then decrease again. The frontal tubercle is rather more distinct 

 than in C. yranti. The eye stands rather closer to the antennal groove. The
