THE CANADIAN ENTOMOLOGIST. 275 



This genus is closely related to Anotnus, Fairm., which, possibly, 

 ought to be arranged to include the type of Multareis. It differs from 

 Anomus in the shape of the head, curve of the apex of the posterior 

 process, tegmina not broad, destitute of hairs, number of discoidal areas, 

 presence of dorsal horns and tubercles on the front of the head ; inflexed 

 head, and tibiae. 

 Type M. cornuius, n. sp. 



M. cornutus, n. sp. — $ , %■ Light ferruginous, strongly punctured. 

 In front of lateral angles, on each side, a tubercle in a fossa coloured 

 black ; tips of lateral angles, upper part of anterior swelling, horns and 

 tip of second posterior tubercle dark ferruginous ; tip of posterior process 

 brownish-black ; tegmina sordid ferruginous, veins dark brown, with two 

 broad transverse bands, the first across the middle, the second between 

 it and the apex sordid white ; tegmina finely punctured, but uneven and 

 rough. Abdomen dark brown, spindle-shaped and robust. Legs ferru- 

 ginous. 



Length, 4 mm.; breadth, ly^ mm. 



Habitat — Panamint Valley, Calif.

Tuber culocentrus, gen. nov. 



Head convex, produced in the middle, large, uneven, coarsely 

 punctured, about half as long as broad between the eyes, which are 

 prominent ; ocelli on a line through the centre of the eyes, much farther 

 from each other than from the eyes. Prothorax between the shoulders 

 elevated in a rounded hump, somewhat flattened on top, densely punc- 

 tured, with a percurrent median carina ; at the base, behind the eyes and 

 in front of the lateral angles, on each side, is a large tubercle in a fossa ; 

 posterior process not reaching the tip of the abdomen, long, very broad 

 at base, gradually narrowed to the beginning of the posterior third, where 

 it is greatly constricted, then broadened considerably and ends at the 

 apex in a sharp point ; when seen from the side it is deeply sinuate 

 behind the hump, slightly so before the apex, which is lighdy elevated. 

 Abdomen long and broad. Scutellum truncated. Tegmina broad, 

 extending far beyond the tip of the abdomen, coriaceous, sub-transparent ; 

 the corium divided into innumerable small areas, no regular arrangement 

 of the veins ; clavus gradually attenuated to the apex. Tibiae triquetrous, 

 not dilated, a row of fine spines on the edge. This is closely related to 

 Centrodentus, Godg.
