all tlie punctures strongly umbilicate. Prosternal lobe finely but distinctly 

 marginod, narrowly rounded ; mesosternum feebly but abruptly and circularly 

 emarginate in median third, the stria entire. Anterior tibije with five small 

 acute teeth, the apical double. Length 4.4-5.5 mm. ; width 2.9-3.4 mm. 



California (Marin Co.). 



In one of the two specimens before me the outer thoracic stria is 

 only a short straight line in apical fourth, not arcuate at apex; in 

 the other it extends to, or a little beyond, the middle and is in- 

 wardly arcuate at apex ; there is however no other perceptible 

 difference, except in size and in the fact that the first mentioned 

 has the mesosternal stria imperfectly interrupted in the middle. 

 Another specimen, taken at San Francisco, is almost similar but has 

 the punctures of the propygidium still coarser, less umbilicate and 

 very noticeably less dense, in fact rather sparse, and the sutural 

 stria shorter. 



H. lllldsonicus. — Broadly oval, Convex, the minute punctules extremely 

 feeble and sparse, becoming distinct punctures toward the apices of the elytra 

 and very near the deep pronotal stria. Head obsoletelj- punctulate, feebly 

 convex, unimpressed, the frontal stria deep and coarse, entire but somewhat 

 uneven, feebly reentrant at apex. Piothorax twice as wide as long, the sides 

 strongly convergent, strongly, almost evenly arcuate from base to apex, the 

 fine marginal stria entire; two marginal punctures distinct; outer lateral 

 stria straight, extending almost to the middle, hooked at apex ; inner coarse 

 and subentire, nearly even, feebly crenulate along the apex; ante-scutellar 

 stria very short but coarse. Elytra distinctly wider than lon^, about one- 

 half longer than the prothorax, at or just before the middle a little wider; 

 sides broadly, evenly arcuate ; inflexed flanks unevenly punctate, unevenly 

 unistriate ; punctures of the lateral series fine, the interstrial series almost 

 obsolete ; outer humeral feeble, subtransverse ; inner feeble, deeper at base ; 

 subhunieral strong, punctulate, subentire, with a transverse inner basal 

 appendage and another oblique and inferior; dorsals coarse, subpunctulate, 

 the first three entire ; fourth slightly abbreviated at base; fifth and sutural 

 equal and apical. Propygidium coarsely deeply densely and evenly punctate, 

 the pygidinm more finely but deeply, very densely so. Prosternal lobe evenly 

 rounded, strongly margined, coarsely punctate laterally ; mesosternum trun- 

 cate, broadly, feebly emarginate in the middle, the stria deep close and entire, 

 subpunctate. Anterior tibife arcuate externally, with about six small serri- 

 form teeth, principally formed by the short stout spinules ; posterior with two 

 even series of slender spines, the inner setiform. Length 6.0 mm. ; width 

 4.7 mm.

Somewhat resembles /b^tZa/i/s, but readily distinguishable by its 

 larger size, more broadly arcuate inner pronotal stria at the apical
