feeble; color dark, with feeble suffused blue or violaceous lustre, the 

 pale form not at hand; abdomen more sparsely punctulate, incon- 

 spicuously pubescent. Length (cf 9 ) 7.3-8.3 mm.; width 2.5- 



3.1 mm. California (Sta. Cruz Mts.), Harford caerulea n. sp. 



A Similar to the preceding, except that the antennae are a little longer; 

 the prothorax is as long as wide, the vestiture throughout slightly 

 longer and bright flavescent throughout on the elytra, legs and 

 under surface, the scutellum densely flavo-pubescent, the elytral 

 punctures more distinct apically and the abdominal punctulation 

 somewhat denser; the legs and tarsi are longer. Length (c?) 

 8.2 mm.; width 2.8 mm. Locality identical.. . chalybea n. subsp. 

 15 Head subtumid basally, shining and not densely punctate. Rather 

 narrowly parallel, not very convex, shining anteriorly, the elytra 

 alutaceous, almost opaque posteriorly; pubescence long, coarse but 

 nowhere dense ; head moderate, finely punctate, the punctures distinct 

 and separated, the broad and ill-defined median line impunctate; 

 eyes not very prominent; antennae short, thick; prothorax a third 

 wider than long, but little narrowed at apex though broadly and 

 strongly constricted, the sides before the middle roundly and gradu- 

 ally distinctly tumid; punctures very fine and sparse, the median 

 smooth line irregular though subentire, the long coarse hairs yellowish 

 like those of the elytra; scutellum not densely, obscurely pubescent; 

 elytra obscure subcupreous, parallel, fully three-fourths longer than 

 wide and three-fourths wider than the prothorax, feebly and arcuately 

 narrowing behind to the rather obtusely rounded apex; punctures 

 not coarse but deep, rather close-set, becoming distinctly asperulate 

 and feeble, with the surface subrugose, apically; abdomen very 

 minutely and feebly, sparsely punctulate. Length (9) 6.2 mm.; 



width 2.6 mm. California (Calaveras Co.) tumidiceps n. sp. 



Head nearly flat above, strongly, very densely punctate and dull; elytral 

 punctures finer apically than basally but not asperulate, the surface 



not becoming duller in lustre 16 



16 Last antennal joint (cf) unusually long, abruptly narrowed in nearly 

 apical half and thence much narrower to the tip. Body not very 

 stout, moderately convex and shining, the vestiture everywhere 

 pale yellowish-cinereous, coarse, hispid and distinct, moderate in 

 length; head moderate, the eyes rather well developed and promi- 

 nent; antennae (cf) thick, extending well behind the middle of the 

 elytra; prothorax unusually elongate, fully as long as wide, barely 

 wider than the head, considerably narrowed at apex and strongly 

 constricted and margined, the ante-medial tumorosity at the sides 

 very broad and barely evident, strongly convex, the punctures 

 small, very deep, perforate and close-set but rather abruptly be- 

 coming very broadly sparse toward the middle, the narrow im- 

 punctate line extending almost to the constriction; scutellum closely, 

 finely cinereo-pubescent; elytra obscure steel-blue, not quite three 

 times as long as the prothorax and three-fourths wider, tapering 

 from base to the rather broadly and obtusely rounded apex, the 

 punctures deep, moderately coarse, separated by but little more 

 than their diameters, finer apically; abdominal punctulation un-
