N. ( cJ ) fuscus, griseo-pubescens ; prothorace grosse 

 corrugatOj elytris multo angustiore, his griseo-seri- 

 cantibus. 



Hah. — Sarawak. 



Dark brown, covered with a close grayish pubescence ; 

 head with two longitudinal grooves between the eyes, 

 uniting below; prothorax much narrower than the elytra, 

 the corrugations rather large, and only slightly intricate 

 and flexuous ; elj'tra grayish silk}*, the exterior apical 

 angle not produced ; body beneath, closely pubescent ; 

 posterior legs only slightly elongate ; antennae very long. 



Length 26 lines ; of the antennae 66 lines. 



I refer this somewhat doubtfully to M. Thomson's 

 JEneas, since he describes the occiput as having an eleva- 

 ted longitudinal line, and gives Bengal as its habitat. 



M, Lacordaire moreover places it with Hoploceramhyx 

 on account of its spinous antennae ; in my specimen, 

 however, the spines are only slightly developed on the 

 fifth and sixth joints, and the general appearance of the 

 insect accords much more with Neoceramhyx. than with 

 Hop/oceranihyx. In N. text or, it is the female which has 

 spined antennas, and not the male.
