pcdibus sordide testaccis, abdominis segmentoriim ventra- 

 lium marginibus rufescentibus. Long. 3^ lin. 



This species is very closely allied to F. varians, but 

 differs from it as follows. It is rather larger, decidedly 

 broader, and less attenuate in front and behind. The 

 colour of the legs is paler, and the segments of the hind 

 body have their hind margins reddish on the under side. 

 The joints of the antennre are considerably stouter, the 

 individual joints not being so narrow at the base as in 

 varians. 



In the male the front tarsi are very strongly dilated. 



This species occurs in Northern China; though only 

 a single female specimen from Japan is extant in Mr. 

 Lewis's collection, it is probably common there. 



8L Philonthus agilis, Grav. Three specimens appear 

 to agree with the description of the European P. agilis ; 

 they are readily distinguished from varians or mutans by 

 the much less dilated tarsi of the male. 



82. Philonthus scyhalaritis, Nord. A number of speci- 

 mens must be assigned to this species, at any rate for the 

 present. But it appears to me that either P. scyhalarius 

 is a very variable insect, or that more than one species is 

 confounded under the name. 



In hay refuse at Nagasaki, common. 



83. P. quisquiliarus, Gyll. One specimen. 



Var. rubidus, Er. Two specimens. At Orakami 

 Marsh. 



84. P. thermarum, Aube. In the absence of sufficient 

 material, I consider it well to place three s]3ecimens found 

 by Mr. Lewis in Japan as this species : they differ from 

 Egyptian specimens by having a deep channel along the 

 front of the head ; they are discrepant from one another 

 in colour. An individual from Northern China shows no 

 trace of the channel on the head.
