l)escril)ed as black, obscure, with piceous antennae and lejjs; head 

 and thorax ru^ioseiy punctate, the latter nai'rowwith thean^les pronn- 

 nent; the elytra iia\'e the suture Hat and the i)unctures of the striae 

 transverse. What island Darwin collecte<l it on is not recorded. 



A specimen collected on S(Mithern Albemarle island by Dr. (1. Ilaur 

 agrees nearly with this description, but may jtrove to 1m^ a. ditlenuit 

 si)ecies. The head and thorax are distiiu^tly alutaceous, tlu' former 

 liiu'ly punctate in front, more strongly behind, the punctures not con 

 lluent ; the thorax is l<mj;iludinally stii^ose, but the punctur«>s are snmll 

 and well separated.
