Remarks. The brown colour markings on the elytra vary greatly in intensity and are 

 sometimes absent. The elytra are thickly covered with small tubercles. The dorsal 

 chaetae are dark brown, stout, upturned and lightly pectinated: the ventral are uni- 

 dentate and with well-developed scales. The last 12 to 14 chaetigers are left uncovered 



by the elytra. 



From St. 140 is one specimen in which the dorsal bristles are to some extent arched 

 over the back, as in H.ferox, Baird (//. rouchi, Gravier). This may be a sexual condition.
