50 J. L. LECONTE, M. D. 



base of the prothorax, with the joints rounded, 1st and 2d thicker, 3d 

 — 8th nearly equal, 9th and 10th gradually a little larger and trans- 

 verse, 11th large, oval, obtusely pointed. 



TYCHUS Leach. 



T. eognatns. — Dark brown, sparsely pubescent ; elytra, feet and anten- 

 nae paler, the latter with Joints 3 — 8 rounded, equal, ninth and tenth larger 

 also rounded, 11th as long as the two preceding, oval, pointed; prothor- 

 rax with a very small narrow fovea near the base, convex, a little longer than 

 wide; elytra convex, with the discoidal stria extending about half the length. 

 Length .00 inch ; 1.5 mm. 



Vancouver Island. Of the same size and form as the Californiaa 

 T. tencllus Lee, but differs by the 9th and 10th joints of the anten- 

 nae being larger, about twice as wide as the 8th. 



DERMEJ^TES Linn. 

 I>. signatns. — Elongate oval, convex, blackish-brown, clothed with brown 

 pubescence, which is more dense from the base of the elytra backwards to 

 behind the middle; near the base ou each is a small dark angulated mark 

 composed of three spots. Length .22 — .32 inch; 5.6 — 8 mm. 



Widely distributed in Northern and Western America; Hudson 

 IJay Territory, Vancouver Island and California. Quite distinct 

 from D. lanhirlaa by the uniform brown color of the pubescence, and 

 by the finer punctuation of the upper surface; the dense pubescence 

 of the elytra sometimes extends nearly to the tip; in other specimens 

 only a little behind the middle, but in all it is prolonged on the disc 

 farther than at the suture and side. 



TROGO DERMA L^r. 



T. Rcirragoi. — Elongate, subcylindrical, black, clothed with scattered 

 grayish-white hairs; head and prothorax very densely, elytra less densely 

 though rather closely j)unotured, with two narrow undulating bands of wiiite 

 and fulvous hair, the 1st about one-quarter from the base, the other one-quar- 

 ter from the tip, base of antennse, tibiae and tarsi brown. Length .22 inch; 

 5.5 mm. 



Texas; Mr. Belfrage, one specimen. Much more elongate than our 

 other species. The club of the antennae is perfoliate, composed of five 

 joints, and is about as long as the preceding joints united. 



KAL.ISSUS, n. g. (Micropeplidce.) 

 Body smooth, shining, sides of prothorax broadly flattened, elytra 

 with two p lirs of approximate striae widely separated behind converg- 

 ing towards the base; abdomen conical not margined; mesosternum 

 moderately wide, deeply excavated for reception of the prosternura ; 

 metasternum with an oblique impres.sed line (somewhat as in Cocci- 

 nella), epimera large, visible as a triangular sp»ce at the sides behind.
