of it, the sternites of segments 3 to liaviiig a series, witli a iinralicr of shorter 

 bristles before them, these bristles being rather more numerous in the ? than in 

 the c?. The steraite of the seventh segment bears abont twelve bristles in the c? 

 and twenty in the ?. It is sinuate in the ? (PI. XIV. fig. 75, vii. st.). 



Legs.— The hindcoxa has a comb or small patch of short spines on the inner- 

 side, and bears three bristles posteriorly at the apex. The mid- and hindfemora 

 bear ventrally two bristles before the apex on the outerside and a smaller one on 

 the innerside. The tibiae bear on the outerside two rows of bristles, the upper 

 row standing close to the dorsal edge. There are seven pairs of dorsal bristles on 

 the hindtibia, the third and sixth jiairs being short and one of their bristles often 

 missing. The hairs of the tarsi are numerous. The longest apical bristle of the 

 first hindtarsal segment does not ((uite reach to the apex of the second. The 

 fifth tarsal segment bears on each side four bristles besides a subapical hair, 

 and on the ventral surface two subbasal bristles on the fore- and midtarsi. The 

 measurements of the tarsi are as follows : — 



Modified Segments. — The eighth steruite of the c? is large, and bears ventrally a 

 patch of numerous hairs. The clasper (PI. XIV. tig. 77, C)l.) is sinuate at the apex. 

 It bears a number of hairs at and near the upper edge, and on the two lobes 

 " p' " and " p^." The finger (f) is conical, with the lower corner rounded ; it bears 

 numerous short hairs. The ninth steruite is very slender, somewhat curved upwards 

 at the apex, bearing a row of four spines apically at the ventral edge followed by a 

 row of four shorter ones. Farther proximal there is a row of slender hairs. 



The eighth tergite of the ? (PI. XIV. fig. 75) bears a number of hairs 

 above the stigma, a row of three or four farther down, and aljont twelve hairs 

 on the ventral half, besides some short ones on the inner surface (punctured in 

 figure). The stylet is conical, being about six times as long as broad. 



Length : cj, 2-2 mm. ; ¥ 2-5 mm. 



We have two examples of this species, collected by Mr. W. Wenraanu : 



1 <?, British Columbia, from Peromi/sei/s leiwojjus. 



1 ? , „ ,, „ Neotoma cinerea. 



32. Ctenophthalmus antiquorum spec. nov. (PL XIV. fig. 72 ; XV. figs. 80. 82). 



This species is allied to the European T. (lasycnemus, but is easily distinguished 

 by the bristles of the thorax and abdomen, by the legs and the structure of the last 

 abdominal segments. 



Head. — The head is practically the same as in T. dasj/cnfimus. 



Thorax. — The prothorax bears two rows of bristles and a comb of eighteen 

 teeth. There are three rows of bristles on the mesonotum, besides a number of 

 hairs situated near the base ; the first row of bristles extends only halfway down 

 the sides. There are on each side of the mesonotum two long slender subapical
