One (^ , recently received by the "" Imperial Bureau of 

 Entomology.'^ Separable from the same sex of H. macidifer, 

 flavinasuSy and trilobatus by the smooth, black, tridentate 

 frontal cavity, the long, rather stout antennae, and the 

 testaceous tibise and tarsi. The elytral fascia is interrupted

 (arising from the outer portions of the epistoma, and 

 infuscate behind) adjacent to it on each side ; antennae very 

 long, stout, tapering towards the tip. Prothorax transverse, 

 convex, rounded at the sides, obliquely narrowed posteriorly.
