bristles along the auteaual j;roove. Tlie eye is traceable at the base of the upper- 

 most spine of the comb. The maxillary palpus is as long as the rostrnm or even 

 a little longer, both reaching to the trochanter or close to the apex of the fore- 

 coxa. The apical segment of the labial (lalpns is much siiorter than the preceding 

 one, being scarcely twice as long as broad. The bristle placed at the posterior 

 corner of this segment is long and strongly curved. The first segment of the 

 antenna bears only a few short hairs, and the hairs of the second segment 

 are all short. 



Thorax — The comb of the pronotnm contains thirteen or fonrteeu spines, the 

 ventral ones being much shorter than the others and also placed farther away 

 from the basal margin, so that the bases of the spines form a curved oblinU'i line. 

 The most ventral spine is plaeed at least as far from the lower edge of the jironotum 

 as do the dorsal spines from the base of the pronotnm. There is a single row 

 of eight long bristles on the two sides of the pronotura together, the ventral bristle 

 being nearer the base of the pronotnm and the dorsal bristles nearer the comb. 

 The dorsal spines of the comb are almost twice as long as their distance from 

 the base of the pronotnm. The mesouotum is as long as the pronotnm inclusive of 

 comb, and a very little longer than the metanotnm, and bears a postmedian row 

 of ten long bristles on the two sides together. The surface between this row and 

 the base is covered with numerous short bristles, with the exception of the ventral 

 portion of the mesonotnra. On tiie inner surface near the apex tliere is a dorsal 

 bristle-like spine on each side. The mesopleura bear four long bristles and some- 

 times an additional small one. Tlie raetauotum has dorsally at the apical edge 

 some minute teeth, but no spines like the abdominal tergites, and bears two rows of 

 bristles, the anterior row containing nine to twelve smaller bristles, and the 

 posterior row eight or nine long ones. The metanotura and metepisternnm are 

 externally almost entirely continuous. The portion corresponding to the episternum 

 is so enlarged ventrad that it is longer in a dorsoventral direction than its distance 

 from the insertion of the coxa. It bears one long and two smaller bristles, while 

 the metasternnm has one long bristle and one short one. The metepimernra has the 

 njiper angle rounded off, the proximal edge moderately rounded, and the distal 

 edge more strongly so. It bears an antemediau row of three bristles and farther 

 upwards a jmstmedian row of three longer ones, the stigma being, placed between 

 the two dorsal bristles of the second row. This stigma is larger than the abdominal 

 ones. Near the ventral margin of the metepimerum, from near the insertion of the 

 coxa obliqnely backwards there is a space which bears, instead of the ordinary 

 nndnlate or angnlate ridges characterising the exoskeleton of Siphonaptera^ 

 numerous regular ])arallel ridges, some of which are continuous with the ordinary 

 ridges of the rest of the metepimerum. 



Abdomen. — Tergites i. to vi. bear short but strongly chitiuised apical spines 

 as follows on the two sides together : in J (>, 6, 0, 4, 2, 2, and in ¥ 6, 6, 4, 2, 2, 2 ; 

 i. to vii. have two rows of bristles, the second row contained on the two sides 

 together 8, 12, 12, 12, 12, 12, 10. The stigmata are jilaced between the two lower 

 bristles of the second row ; they are elongate and but little broader than the groove 

 of insertion of the lowest bristle. The ? bears two long antepygidial bristles on 

 a common truncate jirominence. The edge of the segment is j)roduced dorsally, 

 i.e. in between the antejiygidial pairs of bristles, and sinuate below these bristles, 

 the edge being slightly convex below the sinus and then oblique and almost 

 straight. In the i the seventh tergite resembles the preceding ones, the row of long
