Tills little insect is extremely similar to C. pedtcularmmj 

 but is readily distinguished by the large black setae with 

 which the sides of the elytra are armed ; it is also more or 

 less spotted with black, but apparently in a very variable 

 manner. It is nearly allied to the Australian C. persotmtum, 

 Fauv., but that insect is smaller and has the antennae shorter 

 and more clavate. 



A few specimens were found on the main island at Kashi- 

 wagi, Nikko, and Oyama. 



BOLITOBTUS. 



It appears probable that Eastern Siberia and Japan are the 

 metropolitan regions for this genus. I am enabled to bring 

 the number of species from the latter country up to nine, and 

 in addition to these Mr. Lewis obtained single examples, not 

 in a condition suitable for study, of five others. 



Bolitohius principalis J n. sp. 



Elongatus, capite praesertim elongate, angusto, nigerrimus ; antennis 

 basi flavescente articulis tribus ultimis pallide flavis ; abdomine 

 segmentis tertio quartoque rufis. 



Long. 13 millim. 



This remarkable Bolitohius is no doubt allied to the Sibe- 

 rian B. prcenohilisj Kr., that species having, however, the 

 hind body in greater part red and the antennae different at the 

 extremity. Here the three terminal joints are pale, almost 

 white, and form an abrupt contrast to the preceding joints, 

 which are quite black, the elongate and slender basal joint 

 being flavescent, with a dusky streak above. The narrow 

 head is conico-subcylindric. The thorax and elytra entirely 

 black, the sutural and dorsal series of punctures on the latter 

 each about nine in number. The hind body is coarsely punc- 

 tate, with strong outstanding setae. The legs black, becoming 

 paler towards the extremity, so that the tarsi are reddish at 

 any rate towards the extremity.
