508 ENTOMOLOGICAL NOTES 



prothorax black, with a brown villosity ; elytra perfectly without 

 the usual striae, excepting the pair which runs parallel with the 

 suture, black, slightly tomentose and rugose ; legs, fusco-ferru- 

 ginous. (Length, 1| lin.) 



Taken at Halifax. It somewhat resembles Cat. forme at us 

 at first sight, but is very much smaller, ako blacker ; and the 

 elytra want the striae, so apparent in that species, and have the 

 appearance of rugosity, rather than reticulation, which dis- 

 tinguishes C.fornicatus. These appearances, both of reticu- 

 lation and rugosity, are merely the effect of a different 

 arrangement of minute punctures. 



Cat. soror. Niger, elytris pedibusque piceis. 



Head black ; antennae, with the four basal joints, and half of the 

 fifth, ferruginous ; prothorax black, with a brown villosity ; elytra 

 and legs pitcliy-bla,ck ; the former rugose, faintly striated. 

 (Length 1^ lin.) 



Taken at Halifax. It is more round, and rather shorter in 

 proportion than any other species with w^hich I am acquainted. 

 The antennae also differ ; but the general appearance of this, 

 and the preceding species, is very similar excepting in size; 

 the present is the smaller. These three species are in the 

 eabinct of Mr. Davis.. 



Natural Order. — Byrrmites, ined. 



Genus. — Byrriius. Lhuiceus. 



Byr. rufiventer. Aureo-Juscus,. toviciUosus ; ventre pedi- 

 busque ferrugincis. 



Head, prothorax, and elytra, brown, with a villosity of a golden- 

 brown hue ; antennae black ; the whole undcr-surface and l(^s 

 ferruginous. (Length Z\ lin.) 



Taken round. London, and in many other situations, in 

 abundance ; it has usually been confounded with B. pilula; 

 than which, however, it is smaller, rounder, and different, in 

 beincf invariably of a clear red-brown beneath ; whereas, 

 B. pilula, in the same parts, is invariably jet-black. I find, 

 by iiaving kept specimens alive, that age does not incline the 

 two species to assimilate.
