 stice. In some specimens the strife are more reo-uhir than 

 in others, and in these the spot presents a form which has 

 so often puzzled me to divine the cause in Coleoptera of a 

 detached, pohshed, raised callus, and of which I believe 

 the above is the explanation, the roAvs of punctures having 

 in some instances become fixed after the formation of the 

 tubercle. The colour of the upper surface is bronze, of 

 the underside pitchy, brassy on the sides of the thorax, 

 the abdomen rufous ; legs and antennae pitchy red, knees 

 and club of the latter darker. 



]Mr. Lewis says, " this species is abundant in the South 

 East of Nipon, from Hiogo through Kawatchi to Yoko- 

 hama. I could not find it in Kiushiu, nor has it been 

 received fi-om Yesso. A few examples have been received 

 from Shanghai, so that it may have a fairly Avicle range 

 westAvard. It occurs Avith the Cossus in company Avith 

 Ips Chinensis in elm and Spanish chestnut, is active 

 during June and July in the heat of the day, and Avhen 

 disturbed Avill run and then fall, but rarely takes Aving. 

 It is confined to the plains, not appearing at Ioay or inter- 

 mediate altitudes."
