Coleopterological Notices, V. 545 



Sutural stria generally short, equal to the fifth dorsal and not attaining the 

 middle. 

 Form broadly oval, the inner lateral stria of the pronotnm \ery hroadly 



arcuate at apex lllld^OllicilS n. sp. 



Form narrowly oval, the inner stria strong and narrowly arcuate at apex ; 

 propygidial punctures fine even and extremely dense. 



iinibrosiis n. sp. 



Outer lateral stria completely obsolete, or represented by a few small discon- 

 nected punctures anteriorly. 

 Elytra with four entire dorsal stride, the fourth inwardly arcuate at base ; 



form broadly oval Illiiciis n. sp. 



Elytra with three entire dorsal striie, the fourth more or less abbreviated at 

 base. 

 Form broadly oval, the pronotum punctate toward the lateral stria, the 

 space between tlie stria and the lateral edges more or less convex. 

 Fourth dorsal stria abbi'eviated before the middle. 



iiiariKinicollis Lee. 



Fourth dorsal very nearly attaining the base cogliatlis Lee. 



Form oblong, subparallel, the pronotnm subimpunctate tovvard tlie lateral 

 stria, the latter more distant from the edge, the enclosed space flatter ; 

 fine marginal stria entire and inflexed at base reniotus Lee. 



The characters of marginicoUis are taken from published descrip- 

 tions, but the fine mar^^inal stria of the pronotum is probably similar 

 to that of cognotNS, where it is greatly abbreviated and very diiferent 

 from that of reviotvs ; fcedatus probably does not extend to the 

 Pacific Coast, but is replaced there by the more narrowly oblong'

vmbrosus. I have taken remotus at San Francisco. 



H. lllllbilicatllS. — Narrowly oval, the sides evenly arcuate ; minute 

 punctules feeble, only slightly more evident toward the sides of the pronotum. 

 Head even, not impressed, obsoletely punctulate, the frontal stria entire, 

 transverse at apex. Prothorax not quite twice as wide as long, the sides 

 strongly convergent and almost evenly but feebly arcuate ; fine marginal 

 stria abbreviated at tlie middle, tlie marginal punctures almost obsolete; 

 outer lateral stria greatly abbreviated ; inner strong, more or less abbreviated 

 at base; ante-scutellar stria very small, feeble. Ehjtra one-half longer than 

 the prothorax, and, before the middle, distinctly wider, the sides evenly 

 arcuate; apex rather strongly oblique, feebly rounded ; inliexed flanks con- 

 cave, scarcely punctate, finely unistriate ; marginal series of punctures feeble, 

 not e'xtending before the middle, the interstrial series feeble ; subhumeral 

 stria subentire, with an oblique inferior basal appendage ; outer humeral 

 fine ; inner extending to basal fourth ; dorsals moderately coarse, the first 

 three entire ; fourth slightly abbreviated at base ; fifth present in apical 

 third, the sutural in about apical half. Propygidinm coarsely, closely punctate, 

 the pygidium less coarsely but extremely densely and polygonally cribrate ;
