Legs. — The bristles on the legs are fewer in number than in H. psittaci. The 
fore femur is devoid of bristles on the lateral surfaces. The hind femur, which is 
shorter than in H. psittaci, bears a series of five or six bristles in the $, and four or 
five in the The long bristle of the third dorsal pair of the hind tibia reaches to 
the apex of the tibia, while the longest apical bristle of this tibia reaches to the apex of 
the third tarsal segment. The first mid tarsal segment is distinctly shorter than the 
second. The fifth segment of all tarsi is proportionally much longer than in psittaci, 
this segment being in the hind tarsus of coniger as long as the first segment. The 
number of bristles of this segment is characteristic for coniger. There are in the $ on 
each side four bristles, on one mid tarsus only three, beside the long subapical hair, 
while there are always three bristles in the %. The claw is very slender, and 
shows a slight indication of a basal projection (PI. IV, Fig. 30). The measure- 
ments of the mid and hind tarsi are as follows : —

The hind tarsus is missing in all our 
Modified Segments. — $. The plate of the clasper which bears the dorsal and the 
ventral manubrium is vertically longer than that of H. psittaci (PI. II, Fig. 16). 
The large hairy flap of the clasper (P') has the ventral edge emarginate, the 
ventral apical angle being produced downwards. There are only two bristles on the 
clasper near the base of this process. The second and third lobe of the ninth 
sternite (IX st.) are broader than in H. psittaci. 
The eighth tergite bears externally a row of seven bristles (PI. I, Fig. 9), 
while there are two series of bristles on the inner surface, the proximal row ending 
ventrally in a patch of very small hairs. The bristles on the anal segment are fewer 
in number than in psittaci.

We have one £ and fourteen from Pampa Olliga, Bolivia, a place situated at 
3,000 m. altitude, 67 0 w., and 19 0 s. The late Mr. P. O. Simons found the 
specimens on Conepatus arequipae, 19 October 1901. 
2. Hectopsylla broscus, spec. nov. • 
(PI. IV, Fig-. 29) 
This species is similar to H. coniger, but is easily distinguished from it by 
the following characters . —
