tact : the latter character separates it from Phrissoma, from which 

 it is also distinguished by its non-ventricose elytra and the absence of 

 all irregularities of surface, except at the base, Aconodes, Pasc, 

 to which it is nearly allied, has the basal joint of its antenna) short 

 and fusiform, and scarcely more than half as long as the third. Lastly, 

 Brimus has a habit of its own distinct fi-om all the rest of the Bor- 

 cadionmce, although the female has a certain resemblance to Mr. 

 White's genus Dorcadida. 



Brimus spini])ennis. (PI. XVII. fig. 5.) 



Athemistus [Lamiidse]. 

 Paseoe, Trans. Ent. Soc, 2 ser..v. p. 49. 



Athemistus puhescens. 



A. tuberciilatus, pubescens, rufo-fuscus, setosus ; elytris pone humeros 

 incun-atis. 



Hub. Australia (Port Philip). 



Rather narrower than A. riigosula, covered above with a dense red- 

 dish-brown pubescence, and with longer slender erect hairs interspersed ; 

 head very convex in front ; prothorax nearly round, coarsely pimctured, 

 a small tooth at the side, and a tubercle above it ; scutelliun very small, 

 triangular ; elytra covered with numerous irregular granulations, nar- 

 rowly ovate, very slightly prominent at the shoidder, and rather con- 

 cave behind it, tlie apex entire ; legs moderately robust ; body beneath 

 reddish brown, slightly pubescent. Length 5 lines. 



Resembles A. rugosulus, Guer. (Parmena), but is at once distin- 

 guished by its pubescence. In Major Parry's coUeetion. 



EcHTHisTATtrs [Lamiidae]. 



Head convex in front ; eyes oblong, scarcely emarginate. Antennae 

 setaceous, longer than the body, arising from two diverging tubercles, 

 the basal joint robust aud longest, the third with the remainder sub- 

 equal. Epistome aud labrum small, narrow. Palpi slender, the last 

 joint obliquely trimcate. Prothorax transverse, strongly spined at the 

 side. Elytra short, ovato-conical, each with a nearly central elevated 

 spine, the humeral angle extending beyond the base of the prothorax. 

 Legs long, robust, femora not clavate. Tarsi with the basal joint 

 nearly as long as the two next together. Prostemum toothed. 



The characters which distinguish this genus from Cercegidion con- 

 sist principally, in the diverging antenniferous tubercles contrasted 

 with the remarkably erect and nearly contiguous ones of the latter, 

 in the toothed prosternum, and the long antennae, all the joints of 

 which, except the second, are nearly of equal length ; while in Cerce-
