Occurs from Chiuzenji north to Awomori, and also on the 

 island of Sado, on beech-trees. Commonest in September. 



ECHTHISTATUS ETJECIEEETJ9, n. sp. 



JS. gihhero (Bates) similis, sed diiFert elytris tuberculis parvis 

 rotundatis nigro-nitidis conspersis, una utrinque prope scutellum 

 multo majori. Ochraceo-fuscus, antennis pedibusque piceo-rufis, 

 elytris sicut in JE. gihhero, epipleuris altis verticalibus carinaque 

 flexuosa a dorso separatis ; postice subito declivibus sed declivi- 

 tate multo longiori apiceque longius divergenti-spinoso. Long. 

 15 millim. S ■ 



Hiogo, on Maigasan. 



EOHTHISTATUS GEOSSUS, U. Sp. 



E. gihhero proxime affinis et forsan ejus varietas ; differt elytris 

 a basi pauUo dilatatis, gibbere altiori et latiori, spinis apicalibus 

 latioribus minusque acuminatis ; colore obscuriori, nigro-fusco. 

 Long. 16 millim. 6 . 



Tuyama, in damp forests in May. 



In E. gibher the elytra are broadest at the shoulders, but in 

 E. grossus at the end of the gibbosity, where the tuberculated 

 lateral carina curves round towards the disk. The small tubercles 

 at the base of the elytra, on each side of the scutellum, are much 

 more numerous, about twelve, and larger, forming a linear 

 crest. 



The genus Echthistatus seems to me to belong to the true 

 LamiincB, and not to the Dorcadionince, where Lacordaire placed 

 it, trusting too much to the shortness of the metasternum, which 

 led him to introduce numerous forms into the Dorcadionince sub- 

 family which have their true affinities elsewhere. The cicatrized 

 tip of the scape, one of the chief characteristics of the Lamiinw, 

 is strongly marked in E. gihher and E. grossus, more feebly so in 

 E. hinodosus, and only just perceptible in E.furciferus. 



DOLOPHEADES, UOV. gen. 



Gren. incertse sedis Monohammis minoribus baud dissimile. 

 Parvus, anguste elongato-ovatus. Caput sicut in Dorcadida, ver- 

 tice integro vix concave, post oculos baud impresso. Palpi arti- 

 culis apicalibus ovatis, breviter truncatis. Antennae ( c? ) fere 

 sicut in Monohammo fraudatori (Bates), corporis dimidio lon-
