Head transverse, the frontal canals short and straight, the 

 antenna? slender, the palpi not securiform, the thoi'ax very trans- 

 verse and rectangular, anterior tibiae less strong and palmate than 

 in Carenum and with several smallish teeth externallj'. T have 

 formed this genus for a very curious insect described by me many 

 years ago under the name of Carenum rectangulare ; the Garenum 

 transversicolle, Chaud., will also enter this genus. 



Genus, Laccopterum.

 form, the palpi are triangular, the labrum short, the thorax wider 

 than long, the elytra oval and more or less covered with large 

 fovese, the anterior tibise are strongly tridentate externally and 

 the intermediate have a strong spine on the outer apex. The
