midtarsal segment is ranch longer than the second. The first hindtarsal segment 

 is nearly as long as the liindtilna, and bears nine or ten pairs of short bristles at 

 each side. The apical bristles of all segments are short. The measarements of the 

 tarsi are as follows : — 



Modified Segments. — The eighth tergite is small, while the sternite is very 

 much enlarged and bears numerous heavy and long bristles. The clasper is 

 short and rounded, and bears a few hairs at the edge (PI. XII. fig. 55). The 

 fiao-er (r) is very much prolonged, curved down at the apex and pointed. It bears 

 at the ventral edge a row of long hairs, and some small hairs at the upper edge and 

 on the outer surface. The manubrium (m) is large, acuminate, and curved upwards 

 at the tip. The ventral portion of the ninth steruite is densely hairy at the apex, 

 and bears a lateral lobe as shown in the figure. The spiral of the penis is not 

 coiled, being only slightly curved upwards. 



Length : cj, 4-2 mm. 



We have one cj specimen from Sidapur, India, May 24th, 1901, from the 

 " small jungle squirrel."

Head.— The front of the head bears a distinct tooth. Before the eye there is 

 a series of three bristles, the upper one standing just in front of the eye. In 

 between these bristles, as well as between them and the antennal groove, there 

 are a number of short hairs. The head from these bristles upwards is punctured. 

 The hinder part of the head is similarly pimctured nearly as far down as the 

 antennal groove. There are several small hairs above the antennal groove on 

 the hinder part of the head and one bristle, which is occasionally preceded by a 

 second. The subapical bristles are five in number on each side, the first and 

 second being rather widely apart. The rostrum reaches a little beyond the end 

 of the foreco.Ka, the last segment being about one-fourth longer than the last 

 but one. 



Thorax.— The prouotum bears one row of bristles and a comb of eighteen 

 or nineteen teeth. On the mesonotum there are two series of bristles and a 

 subapical comb of about sixteen hair-like spines on the two sides counted together. 

 There are also a number of small hairs at the base. The episternum of the meso- 

 thorax bears several small hairs in front, one or two longer ones in the centre, 

 and one or two bristles behind. On the mesothoracical epimerum there are five or 

 six bristles— two or three in front and three behind. The metanotum, which is 

 much shorter than the mesonotum, bears two rows of bristles and a few hairs on 

 the back, and possesses on each side two or three short stout apical spines on each 

 side. There are three long bristles on the metathoracical epimerum— one near the 

 hinder edge, one just below the stigma, and the third farther down. Besides 

 these there is generally one shorter bristle below the stigmalical one, and two or 

 three are placed towards the base. 



Abdomen.— The abdominal tergites bear each two rows of bristles; tergites
