Phytophagous Coleoptera of Japan. 160 



This insect closely resembles N. A^-signatum, Motsch., 

 both in form and coloration : it may be at once known by 

 the deep punctuation of the thorax.

Ovatum, convexum, nigrum, nitidum, antennis flavis, 

 extrorsum infuscatis, labro pedibusque fiilvis ; thorace trans- 

 verso, pone medium angulato, fortiter punctato ; elytris 

 subfortiter punctato-striatis, nigro-piceis, utrisque macuU 

 parva basali, intra humeiiim posita, pallide flava, ornatis.

Hah. — Nagasaki, Tsu Sima. 



Head deeply punctured ; front impressed vfiih. a longi- 

 tudinal groove ; eyes bordered above by a sunken orbit. 

 Thorax nearly one-third broader than long ; sides angu- 

 late behind the middle ; above convex, subcylindrical at 

 the apex, deeply punctured ; anterior margin narrowly 

 edged with fulvous. Elytra broader than the thorax, con- 

 vex, transversely excavated l^elow the basilar space, regu- 

 larly punctate-striate, the punctures finer on the basilar 

 space and towards the apex ; shining black, humeral 

 callus sometimes rufo-piceous ; at the base of each elytron,
