The type of this genus is Hammaticherus spinicollis, 

 "Newm., described from a female specimen ; individuals 

 of several of the species appear to vary greatly in size, 

 as well as in some of their characters ; in the larger 

 specimens, for example, the last joint of the antennae is 

 considerably longer than the preceding one, while in the 

 smaller ones it scarcely exceeds it. 



Hoploceramhyx severus. 



H. piceo-fuscus, pubescens ; capite valde producto, collo 

 valde elongate ; prothorace rugis fere integris. 



Hah. — Waigiou, ' New Guinea,^ 



Pitchy-brown, finely pubescent ; head much produced, 

 the neck very long, finely corrugate behind the inter- 

 ocular canal, the two tubercles above the clypeus nearly 

 filling up the transverse groove ; prothorax moderately 

 elongate, the corrugations scarcely flexuous and nearly 

 entire, the pubescence very short and delicate ; elytra 

 almost obsoletely punctui'ed, each with three very indis- 

 tinct longitudinal lines ; body beneath, with very short 

 minute scattered hairs, each arising from a small punc- 

 ture ; legs rather long, femora finely corrugated ; 

 third and fourth joints of the antennas roughly punc- 

 tured. In the female the head is shorter, but the neck is 

 also corrugate as in the male ; the elytra are much 

 broader, and have a very decided ovate outline, and the 

 antennae are much shorter, and, except the scape, not 

 rugosely punctured. 



Length 30 lines. 



This very fine species is at once known by its long and 

 almost uninterruptedly corrugate neck.
