Differs from tlie typical species of the genus by Its large, conical, 

 thoracic, lateral tubercles uot terminating lu a spine. It may be 

 readily distinguished by the rounded patch of light coloured tomentum 

 on each side, covering the hinder part of the lateral tubercle, and ex- 

 tending towards the base. The dorsal thoracic tubercles are trans- 

 versely placed and not much elevated. The elytra have large, obtuse, 

 centro-basal tubercles ; they are variously spotted with ashy tomentum, 

 which condenses about the middle and forms a fascia ; the scattered 

 large punctures or foveas about the disc and apex are a good dlsthiguish- 

 Ing character. The antennre in the males are one-third longer than 

 the body, clothed with long hairs beneath, dark pitchy In colour, with 

 the 3rd and 4th joints much elongated.

The thorax has a small and conical lateral tubercle, not terminating 



In a spine, and on Its disc two small glossy transverse tubei'cles ; the sides 

 are clothed with spai'se cinereous pubescence. The elytra have distinct 

 compressed centro-basal tubercles crested with bristles ; they are 

 more densely clothed with pubescence than In H. pedator, so that the 

 punctuation is not conspicuous ; behind the scutellar region is a broad, 

 cinereous fascia, followed by an Interrupted black belt, behind which 

 is a large fulvous patch on the suture, and the disc behind has two or 

 three raised lines. The whole insect is clothed with long grey hairs, 

 especially conspicuous on the legs. The antenna; are ringed with pale 

 testaceous, and their 3rd and 4th joints are only moderately elongated. 

 The species has much the appearance of a Pogonocherus, to which 

 genus Hj/holasius, as well as the Australian genus Hehescesis, Is very 

 closely allied.

A small species ; moderately convex and clothed with long, erect
