406 THE ZOOLOGIST. 



In the female the seventh sternite is rounded ; the bristles 

 of the second antennal segment are less than one-third the 

 length of the club, and the proportional width and length of the 

 stylet are 1 : 4.3. 



Alberta, Canada, off Microtus drummondi and Evotomys 

 saturatus. 



8. Amphipsylla kuznetzovi, Wagn. (1912). 



Amphipsylla kuznetzovi, Wagner, Kev. Eusse Ent. xii. p. 579, 

 fig. 5 (1912). 



Only the male is known. 



The movable exopodite of the clasper is rather abruptly 

 widened in the apical half, bearing three black spiniform bristles, 

 one of which is placed on the inner surface half-way between the 

 anterior and posterior margins/ The eighth and ninth sternites 

 are not described or figured. 



Ural Mts., off Microtus middendorfi. 



9. Amphipsylla contigua, spec. nov. (PI. II. and III., figs. 1, 5, 



and 6.) 



Very close to A. kuznetzovi. 



The hind tibia bears usually three, rarely two, bristles between 

 the postmedian dorsal pair and the subapical pair. 



$ . The eighth tergite has three long and one or two small 

 bristles. The eighth sternite (PI. II., fig. 1, vm. st.) bears 

 bristles only at and close to the margin, there being fourteen or 

 sixteen bristles placed as shown in the figure. The process P of 

 the clasper (CI) is dorsally convex and distally concave. The 

 movable process F resembles that of kuznetzovi, but is more 

 gradually widened distally and bears only two black spiniform 

 bristles. The upper one of these bristles is very stout and placed 

 near the upper distal corner, while the lower one is longer, 

 pointed, and situated near the posterior margin on the wide 

 part of the process a short distance from the narrow portion. 

 Between these two spines there are two bristles at the edge on 

 the outer surface, and two more on the inner surface at some 

 distance from the edge. The apical margin bears one fairly 

 long thin bristle, and in addition on both the outer and inner 

 surfaces a thin hair placed at about half-way from the long
