SOME NEW EXOTIC FLEAS. 



BY THE HON. N. CHARLES ROTHSCHIID, M.A., F.L.S. 



PTGIOPSYLLA, qen. nov. 



? . Frona without tubercle ; a row of bristlos from the palpus running obliquely 

 upwards. Two oblique rows of bristles on the occiput, besides a subapical row. 

 Pronotum with at least two rows of bristles and a comb. Episternum of meta- 

 thorax large. Seventh abdominal tergite with at least one apical bristle situated 

 below those which are placed on a cone. Sensory plate (so-called pygidium) strongly 

 convex, projecting backwards. First midtarsal segment longer than second. Fifth 

 tarsal segment with five bristles on each side. 



Type : P. hilli, Eothsch. {Ceratophylluii) . 



To this genus belongs the species described as OeratophyJlus hilli, 

 ahalcd, rohinsoni, novceguinece, tvoodtvardi, rofJiscJiiJdi, and echidnce, as 

 well as the new one here described. 



Ptgiopstlla colossus, spec. nov. (Fig. 1). 



$ . A very large species, resembling in size P. eehidnse, Denny. 



Head: — The maxillary palpus is very long, nearly 

 reaching to the apex of the fore coxa. The second 

 segment is twice the length of the first and about 

 one-third longer than the fourth. The labial palpus 

 extends to the apex of the trochanter ; it consists 

 of five segments, of which the fourth is the longest, 

 as is the case in P. M/2, Eothschild (190i). The 

 bristles of the frontal row are thin ; between this 

 row and the eye there are numerous hairs and three 

 long bi'istles, one standing in front of the eye. The 

 occiput bears numerous small hairs at the antennal 

 groove, arranged irregularly. 



Thorax :— "The thorax and abdomen are densely 

 covered with small hairs on the back. The pronol um 

 bears three rows of bristles and some additional hairs. 

 The comb consists of 20 teeth, these being a little 

 Fig. 1. ' over half the length of the pronotum. The mcso- 



notum is dorsally a little longer than the pronotum inclusive of the comb, and 

 one-fourth longer than the metanotum. The sternum and epimerum of the ineso- 

 thorai bear altogether about twelve small bristles. There are three hairs at the 

 upper hinder angle of the sternum of the metathorax, the episternum bearing 

 two hairs, while there ai'e about 24- small bristles on the epimerum. 



Abdomen : — The first tergite is strongly narrowed anteriorly, being longer than 

 the mesonotum. The second and third tergites bear a tooth on one or both sides. 

 The hairy dorsal area does not extend below the stigma, except the postmedian row 

 of bristles. There are on the seventh tergite two apical bristles situated on cones, the 

 upper one being less than half the length of the lower. Below them there is a third 

 bristle which is shorter and is not placed on a cone. The first sternite bears only a
