170 Mr. G. Lewis on the Pyrochroidge of Japan. 



I possess six females, but do not know the male. The 

 localities for it are Ichiuchij Siibashiri, Mijanoshita, and 

 Oyajama. 



Pi/rochroa hrevitarsis, 



Elongata, nigra, subnitida ; fronte transversim subexcavata, inter 

 antennas subelevata ; pronoto parum transverso utrinqne biangu- 

 lato ; elytris testaceo-brunneis. L, 8| mill. 



Head with an interantennal elevation with a median but 

 small tubercle, the transverse space between the eyes and 

 antennae is slightly excavated. The thorax is anteriorly 

 straight behind the neck, and then shelves off to a point, 

 which, viewed over the elytra, looks like an angle ; posteriorly, 

 as in laticollis, there is another well-defined angle. The scutel- 

 lum is black, and the thoracic depressions do not visibly 

 differ from those of the preceding species. 



There is no doubt about this species being distinct from the 

 last on account of the size, thoracic angles, and shorter poste- 

 rior tarsi. 



Two examples, both females, were taken in the highest 

 region of Kadzusa, April 5, 1880. In this part the planta- 

 tions are chiefly of Ahies and Pinus. 



It is the smallest species known from Japan at present. 



Pyrochroa peculiaris. 



Elongata, nigra, subnitida ; fronte bifoveolata ; elytris piceis pilo 

 rufo-brunneo. L. 9-11 mill. 



Elongate, black, little shining. Head and thorax with an 

 ashy pubescence ; elytra piceous and clothed with a reddish- 

 brown pile, which gives a peculiar dark tint to the whole. 

 The forehead in the male has two deep fovese between the 

 antennae, and the transverse space between the eyes and the 

 antennae is thickly clothed with pubescence ; between the 

 eyes the surface is sparsely puncticulate ; neck rather thickly 

 punctate. The first joint of the antenna is somewhat com- 

 pressed, second trigonate, third with a subapical branch, 

 fourth to tenth with pectinal processes longer than the joints. 

 The female has no frontal foveae, but the transverse depres- 

 sion before the eyes is more distinct, the head generally more 

 thickly punctured, and the antennae obtusely pectinate. 

 The thorax is round in both sexes, and the elytra but mode- 

 rately dilated and rugosely sculptured. 



I took this species in August, four specimens in South 

 Yezo and one on Niohozan, above Nikko.
