Longicorri Coleoptera of Japan. 385 



Similar in form to E. halteatus ; but tlie antennse decidedly 

 thicker and densely clothed with long hairs. Thorax of very 

 similar form. General colour brownish red. The elytra rather 

 densely and irregularly clothed with erect hairs ; each elytron 

 has the suture and five lines grey ; all (except the sutural) 

 interrupted behind the middle by a broad zigzag fascia of the 

 ground-colour, beyond which, near the apex, three short lines 

 only reappear. 



Exocentrus tonsus, n. sp. 

 E. halteato forma similis, at multo minor, haud setosus. Oblongus, 

 testaceo-fuscus, incumbenti-pubescens ; capite thoraceque obscu- 

 rioribus, subtiliter crebre pimctulatis, hoc spina laterali minus 

 obliqua ; elytris subUneatim pimctulatis, maculis traiisversis ir- 

 regulariter sparsim nebulosis ; antennis corpore longioribus, graci- 

 libus, haud setosis. Long. Ij-lf lin. 



Nagasaki ; on ivy. 



E. oblongus, convexus, subaeneo-niger, griseo-olivaceo pubcst-ons ; 

 elytris erecte setosis, pube griseo-olivacea lineatim guttatis et 

 pone medium fasciatis; antennis ciliatis, articulis basi griseo- 

 testaceis. Long. 31 lin. 



One example. 



Head and thorax rather smaller and elytra more ample than 

 in E. halteatus ; thoracic spine broad at the base, oblique and 

 acute. Elytra subseriate-punctulate, with single, erect, black 

 bristles and oblong spots of olive-grey pubescence arranged in 

 lines ; a belt of similar colour a little after the middle. The 

 antennaj elongated, as in E. halteatus^ moderately pubescent, 

 and finely ciliated beneath. 



AsAPERDA, nov. gen. 



Facies Saperdarum, sed unguibus divergentibus, simplicibus. 

 Elongata, linearis. Caput exsertum, postice dilatatum. Oculi 

 fere divisi. Antennoe tenues, tihformes ; scapo modice elongate, 

 cylindrico-ovato. Thorax transversus, postice constrictus, tuber- 

 culo valido laterali armatus. Elytra apicc rotuudata, simplicia. 

 Pedes breves ; coxcb anticse extus angulata; ; acetabida intermedia 

 extus aperta ; tlhioi intermediae extus sulcatue et tuberculatae ; 

 sterna inter coxas simplicia. 



This genus does not fall naturally into any of the numerous 

 " groupes " into which Lacordaire divides the Lamiadje with 

 simple antennal scape. It agrees best with the Apotuccynina;^ 

 and has some resemblance to Kanidia, except its longer body 

 and stout thoracic lateral tubercles. I should be inclined to
