ous short spines with a fringe of long spines along the posterior mar- 

 gin and a cluster of short heavy spines at the apex of each plate. Third 

 segment with a cluster of stiff, heavy spines at the apex of each plate. 



Ventrally there are apparently six sternites. The first occupies 

 about a third of the abdomen and bears along its posterior margin the 

 usual comb. Second segment membranous, beset with numerous short 

 spines arranged in more or less regular rows, each spine set upon a 

 chitinous papilla. Remaining sternites short and not extending across 

 the abdomen, the lateral margins being filled by the pleurites of the 

 apparent third dorsal segment, each of these sternites beset with numer- 

 ous spines, the last having a cluster of stiff spines at each posterior 

 lateral angle. 



$ . Length, 3 mm. Head and thorax as in female. 



Abdomen elongated, truncate at the tip. Dorsally there are seven 

 segments each of which bears a pair of spiracles. First segment very 

 short, indistinctly separated from the second. Second to sixth sub- 

 equal in length. Seventh as long as any other three, about twice as 

 wide across the anterior margin as across the posterior. Second to 

 fourth segments with a row of slender spines along the posterior mar- 

 gin and a few short spines on the disk. Fifth and sixth segments with 

 numerous very long stout spines along the posterior margin. Seventh 

 with a number of stout spines on the disk and at the apex. Ventrally 

 there are visible but five sternites, the first four subequal in length. 

 First segment with numerous short spines on the disk and with the 

 usual comb along the posterior margin. Second and third sternites with 

 numerous short spines and with a row of slender spines along the pos- 

 terior margin. Fourth with a row of slender spines along the posterior 

 margin the median portion of which is occupied by a group of short 

 and very heavy, almost tubercle-like, spines. Claspers on the last seg- 

 ment long and slender reaching to the anterior margin of the seg- 

 ment. 



Penicillidia corynorhini n. sp. (PL XXIII, fig. 3.) 



A single female, taken from Corynorhiiins toztniscndi 

 (White River, Tulare County, California) which, according to 

 Miller, "List of North American Land Mammals in the United 

 States National Museum, 1911," is probably Corynorhinus uia- 

 crotis pnUescens. The species is very distinct, differing from 

 P. antrosoi in the remarkable backward prolongation of the 

 first dorsal segment of the abdomen, in the short, broad head 

 and in numerous minor details. A direct comparison with any 

 of the European species is not possible, due to the insufficiency 

 of the descriptions.
