30. Ctenopsyllus brooksi* spec. nov. (PI. XV. fig. 86. 88; XVI. fig. 89). 



Head.— The front of the liead is vertical (PI. XV. fig. 86, S), being much 

 more rounded in the ¥ than in the S. Tliere is an oblique row of si.x long 

 bristles, and a single long bristle below this row at the antennal groove. There 

 are, besides, numerous short hairs scattered over the lateral surface. There are 

 five genal spines, of which the second is the longest. Between the second and 

 third spine, counted from below, there projects the sharp hinder corner of the gena. 

 The hinder part of the head bears two oblique rows of bristles and a subapical 

 row. The club of the antenna bears numerous minute hairs in the c?. 



Thorax.— The pronotum has a comb of about fifty to fifty-six spines in the c?, 

 and thirty to forty in the ?. There are two rows of bristles, besides numerous 

 additional hairs situated in front and on the back. The mesonotum is very hairy 

 in front and on the back. There are about eight long bristles in the postmedian 

 row. The mesonotum bears about five long subajiical spines. On the episternum 

 and epimerum of the mesothorax there are together about sixteen bristles, besides 

 some small hairs. On the metanotum there are three rows of bristles, the first 

 being irregular, and an interrupted row between the first and second, besides some 

 additional hairs in front. The metanotum bears, moreover, three long hair-like 

 spines dorsally on each side near the apex. On the epimerum of the metathorax 

 there are fourteen to eighteen bristles, while the episternum bears two very long 

 bristles, besides three or four shorter ones. 



Abdomen. — The first abdominal tergite bears four rows of bristles; and some 

 additional hairs in between. On the second tergite there are two rows, and several 

 hairs laterally in front. On the other tergites there are two rows, the anterior 

 row being generally incomplete and mostly preceded by some hairs representing 

 a third row. The first tergite bears on each side two to four apical spines, the 

 second four, the third two or three, the fourth one or two, and the fifth none or one. 

 The seventh tergite has in the S one long stout apical bristle, and in the ? two 

 on each side. In front of these bristles there are several hairs, in addition to 

 the hairs of the postmedian row, the additional ones being especially numerous in 

 the c?. The first abdominal sternite bears a ventral bristle and some extremely 

 short hairs on the side. In the (S the sternites of segments 3 to 7 bear a row of 

 bristles, with one or two bristles in front, there being four or five bristles in the 

 row of the anterior sternites, the number increasing gradually to eight or nine as 

 we proceed backwards. The number of these bristles is larger in the ?, the 

 bristles in front of the row being especially numerous. The seventh sternite of 

 the ? , which is broadly sinuate (PI. XVI. tig. 89, vii. st.) bears as many as twenty- 

 eight bristles. 



Legs. — The hindcoxa has on the inner surface a regular comb of nine or ten 

 spines, and bears posteriorly at the apex two bristles. The mid- and hindtibiae 

 are very hairy, bearing on the outerside two lateral rows of hairs, besides a number 

 of ventral hairs. The dorsal bristles are very long and stout, there being eight 

 pairs on the hindtibia. The longest dorsal apical bristle of the midtibia reaches 

 beyond the apex of the first tarsal segment, while that of the hindtibia does not 

 quite extend to the apex of that segment. The lateral bristles of the tarsi are 

 numerous and long, the short hairs on the ventral and dorsal surfaces being also
