A singular Lathrobioid species. The antenna^ are long 

 and slender, and reach nearly to the extremity of the 

 elytra : 3rd joint long and slender, much longer than the 

 2nd; all the rest of the joints much longer than broad, the 

 last paler than the rest. The mandibles and palpi are 

 yellowish. The head is narrow, but rather broader than 

 the thorax ; it is narroAved behind the eyes ; it is of a 

 black colour, i-ather finely and closely punctured, with the 

 disc impunctate. The thorax is very peculiar in form ; it 

 is much narrower than the elytra, and very elongate, being 

 more than twice as long as broad ; it is not narrowed 

 behind, but ajipears somewhat narrowed in front, owing to 

 the front angles being greatly inflexed ; it is strongly 

 sinuate at the sides before the hind angles; it is of a 

 reddish colour, and has on each side the middle a dorsal 

 row of five fine punctures, and has also a fcAv other fine 

 punctures on each side. The scutellum is finely punc- 

 tured. The elytra are not so long as the thorax, i-ather 

 finel}' and closely punctured. The hind body is elongate 

 and slender, yellowish, Avith the 5th and 6th segments 

 broadly infuscated ; it is closely, finely and evenly punc- 

 tured. The legs are yellow, long and slender. 



Ega ; one specimen.
