NEW GENERA OF COLEOPTERA. 507 



Subrugose, of a mouse-coloured greenish grey, loosely powdered with 

 white scales ; the rostrum irregularly and minutely denticulated 

 above throughout its whole length, the two apical teeth and the 

 two between the insertion of the antennae considerably the 

 largest, the former recurved: the thorax with a large compressed 

 fascicle of brown hair (skirted behind by a few white ones) on 

 each side just before the middle, from the base of which an irre- 

 gular brown stripe, (composed of minute scales,) which gradually 

 widens as it extends posteriorly to the margin of the thorax, and 

 irregularly encircles the fascicle in front; a deep longitudinal de- 

 nuded black channel proceeds from the constriction of the neck 

 to the base of the scutellum, which is quite white : the thorax 

 beneath black and shining, and transversely wrinkled : at the base 

 of the anterior coxas there is a large white irregular spot placed 

 laterally upon the antepectus, and a large brown one between the 

 intermediate and posterior pairs : the elytra are less distinctly 

 speckled with white than the thorax, longitudinally striated, these 

 strias converging in pairs at the apex, the interstices convex, and 

 thus forming a series of tencostaa upon each elytron,the internal ones 

 most distinctly marked; upon the second, third, and fourth from 

 the suture on each side there is a small fascicle of brown hair, that 

 upon the fourth being in advance of the others, and at about one- 

 fourth of the length of the elytra, and placed obliquely with re- 

 ference to that upon the second costa, whilst that upon the third 

 is more distant from the latter, and with it parallel to the suture ; 

 closely behind that upon the fourth, and in front of that upon the 

 third, there is a more delicate but longer fascicle of white hair ; 

 and behind the latter, at equal distances, are two others, parallel 

 to the last of which, and upon the next (the fourth) costa, one 

 other ; there is also the vestige of another white fascicle projecting 

 from the side at rather more than one-half the length of the elytra, 

 and placed upon the ninth costa from the suture : there is an in- 

 dication of three brown fasciae, marked obliquely, and extending 

 internally to the suture, the first commencing from the side, at 

 about half the length of the elytra ; these as well as other brown 

 marks mottle the surface, their positive course being but obso- 

 letely indicated ; the sutural costse and the base of the third are 

 much more elevated than the rest, and there is a large deep 

 depression just within the humeral angle, and a protuberant gib- 

 bosity within the inner angle of the convergent striae, towards the 

 apex of the elytra : the legs are black, sparingly covered with 

 white scales, and having a longitudinal brush of pale hair at the 

 base beneath of the intermediate and posterior femora : the inner
