690 Coltopterological Notices, IV. 



lel-sided, not increasing much in thickness, with the articulations deep ; club 

 large, as long as the preceding five joints, complex in structure, the basal half, 

 composed of the modified seventh funicular joint, obconical, as long as wide, 

 polished and sparsely setose, the apical paler, oval, obtuse, densely pubescent 

 and indistinctly annulate. Scutellum small but distinct. Metasternnm short. 

 Anterior coxje large, globular, extremely approximate ; intermediate very 

 narrowly separated ; posterior rather remote. Legs somewhat long and thick ; 

 femora sinuate beneath near the apex ; tibife snbparallel, the apical uncus 

 well developed, the anterior also with an internal subapical tooth; tarsi 

 cylindrical, rather stout, the third joint scarcely visibly thicker and sparsely 

 setose beneath, not bilobed. 



From Gononotus this g-enus differs in its composite antennal club, 

 undilated third tarsal joint, elongate prothorax, smooth, polished 

 head and many other characters. 



M. repeus n. sp. — Elongate-ovoidal, convex, dull, black and subgla- 

 brous, each large fovea, however, with a small fulvous seta; there are also 

 a few clusters of such setse on the more tumid portions of the elytral intervals. 

 Head glabrous; beak not quite as long as the prothorax, dull, with coarse 

 sliallow punctures, sublinearly arranged but becoming finer and irregular to- 

 ward apex. Prothorax quite distinctly louger than wide, the sides parallel, 

 broadly feebly and evenly arcuate, rather abruptly rounded and moderately 

 deeply constricted behind the apex, the latter three-fourths as wide as the 

 base and broadly sinuate in the middle ; base broadly feebly snd evenly arcu- 

 ate ; disk evenly, feebly convex, very coarsely, remotely foveate, the fovese 

 shallow, rounded, and annulate just within their edges with fine cinereous 

 tomentum ; median line finely and strongly carinate, the carina attaining 

 neither base nor apex. Elytra oval, at the middle one-half wider than the 

 prothorax, not quite twice as long as the latter ; humeri obsolete ; base broadly 

 emarginate ; disk with series of very large deep and unevenly impressed fovere, 

 the intervals uneven, not wider than the series and remotely, feebly tumorose, 

 the tumid parts setose and also finely cinereo-tomeutose. Under surface 

 coarsely, remotely foveate, the fovefe shallow. Length 5.2 mm. ; width 2.(> mm. 



California (Humboldt Co.). 



I took the type specimen in some loose mossy turf, covering- the 

 gravelly slopes of a shallow ravine near the town of Areata ; its 

 sex is not apparent. This is one of the largest cossouides in our 

 fauna excluding the genus Cossonus. 



HIMATIUM Woll. 



There is some doubt concerning the actual identity of Wollas- 

 ton's genus with the species assigned to it by LeCoute. Accord- 

 ing to the description, however, it must be very closely allied to
