There are traces of a fine cinereou.s pubescence above and below. 

 Palpi with last joint oval, obliquely truncate at tip. The small size 

 and strongly striate elytra and other characters di.stinguish this. 



8. C geniinifer u. sp. — Very small, shining, black, with yellowish cinere- 

 ous pubescence, elytra each with two spots. Antenna> black, slender and feebly 

 serrate, stouter in the *£ and longer than the head and thorax. Head and tho- 

 rax moderately punctnlateand with sparser, coarser punctures. Thorax as wide 

 as long, moderately convex, sides rounded, more narrowed in front, obliquely 

 narrowed behind, more or less longitudinally impressed behind the middle, the 

 impression sometimes more linear and deeper, hind angles produced, not diver- 

 gent, the carina joining the submarginal behind, median basal lobe feebly tri- 

 dentate. Elytra rounded at the sides, a little wider than the thorax, .striiB hardly 

 impressed, punctured, less distinct at apex, intervals punetulate, a .small yellow 

 spot before the middle and a larger, usually paler one before the apex; in one 

 specimen, a 9 (California), the anterior spots are quite absent and the posterior 

 ones are very small. Body beneath with the usual double punctuation, but it is 

 not very strong, sides of prothorax without coarser punctures, the submargiual 

 line carinate, reaching beyond the middle, hind angle a little sinuate inside, in- 

 tercoxal process short, margined beneath and distinctly ascending, hind coxal 

 plates dilated externally behind.. Legs slender, rufous, thighs darker. Length 

 .'20 inch ; 5-6 mm.

Very distinct by the characters given. 



9. CJ. tiimidicollis Lee— Form short, rather robust, black, shining, or 

 sometimps slightly obscure, clothed witli fusco-cinereous pubescence. Legs 

 sometimes partly rufous. Antennfe black, second joint two thirds as long as the 

 third, which is equal to the fourth, stouter in the % , as long as the head and 

 thorax, gradually more slender towards the tip. Head and thorax moderately 

 or densely and strongly punetulate, with sparser, coarser punctures intermixed. 

 The thorax is a little broader than long, convex, rather more so in the $> , fre- 

 quently finely longitudinally impressed at middle, sides rounded, narrowed in 

 front and obliquely less narrow^ed behind, not or obsoletely sinuate, basal plica? 

 rather long and well marked, hind angles prolonged and carinate, the submar- 

 ginal line joining the carina at the apex of the angle; the basal lobe is strong 

 and tridentate. Elytra moderately convex, two and one-half times the length 

 of the thorax, sides rounded, narrower iti front, striae moderate, with subquad- 

 rate or elongate punctures, intervals flat or feebly convex, and more or less ])unc- 

 tulate, sometimes finely rugose. Body beneath shining and moderately punetulate, 

 coarser punctures, very feebly evident on the prosternum. more distinct on the
