Genera and S])ecies of Colcoptcra. 101 



small and mostly white scales, except on the sides of the latter, where 

 they are drawn out into long, linear, ciu-ved laminoe, on each side a long 

 fascicle of whitish hairs mixed -s^dth black, and nearly meeting on the 

 median line anteriorly ; scutellum triangidar, with a tuft of ei'ect white 

 scales ; el\i;ra parallel, the scales towards the suture principally white, 

 but more or less black at the side, long and filiform at the base, and 

 spatiilate on the exterior margins, a fascicle of long, erect black scales 

 on the middle of each near the suture, and posteriorly another of mixed 

 black and white scales; body beneath, legs, antennae, and lip dark 

 brown or nearly black. Length 4 lines. 



In this cui'ious species, the lines on the elytra arc nearly covered 

 by the longer and more densely set scales. In all the Australian 

 and New Zealand LeperhuB which I have examined, I have never 

 noticed any other than simple, undivided eyes. 



Leperina lacera. 



L. oblonga, picea, supra nigro-squamosa, albo varia, fasciculisque brevibus 

 induta ; elytris lateribus rotundatis. 



Hab. Austi'alia (Melbom-ne). 



Oblong, pitchy-brown, partially coA'ered with short black scales, and 

 sparingly varied with white ; head coarsely pimctm-ed, with two black 

 fascicles between the eyes ; prothorax with a smooth elevated median 

 line, the sides strongly and deeply pimctm-ed, above fom- short black 

 fascicles anteriorly, the margins densely covered with long, white, ap- 

 pressed scales ; scutellum triangidar ; elj^tra roimded at the sides, the 

 scales almost entirely black, spatulate at the margins, with a single 

 short black fascicle on each shoulder ; body beneath, legs, and antennae 

 dark ferruginous. Length 4^ lines. 



BiTOMA [Colydiidae]. 

 Herbst, Die Kiifer, v. p. 25. 



Bitoma serricollls. 



B. depressa, fusca ; prothorace puuctato utrinque bicostato, lateribus ser- 

 rulatis ; pedibus rufo-feiTugineis. 



Huh. Australia (Melbom'ue). 



Depressed, dark bro-wTi ; head coarsely pmictm-ed, grooved at the side 

 below the eyes, and somewhat three-lobed anteriorly ; prothorax trans- 

 versely subquadi-ate, coarsely punctm-ed, with two costae on each side, 

 the exterior crenate, continuous with its fellow in front, the sides strongly 

 seiTulate, the anterior angle produced ; elytra a little wider than the 

 prothorax, with five narrow costoe on each, the intervals transversely 

 plicate from a double row of deeply impressed punctm-es ; antennae and 

 legs rusty-red ; body beneath coarsely punctured. Length 2 lines. 



A little broader and more depressed than Bitoma crenata ; but, as 

 far as external characters go, there can be no doubt as to its genus.
