ClCINDELID.E AND CARABID^E IOI 



Body black but much more depressed, shining throughout in both sexes 

 and much more flattened on the upper surface, more explanate and 



more broadly margined at the sides of the elytra 4 



4 Form elongate, parallel, not very intense black, the under surface 

 and legs frequently picescent; head not so large as in serripes, three- 

 fifths as wide as the prothorax, the epistoma and labrum similarly 

 broadly sinuate from side to side, the antennae not quite so long or 

 thick, scarcely extending to the thoracic base, rufescent at base; 

 prothorax widest anteriorly and about equal in width to the elytra, 

 moderately narrowed and broadly, feebly sinuate at the sides basally, 

 the base broadly and distinctly sinuate medially, four-fifths the 

 maximum width; surface almost flat, the median stria strong; 

 inner of the lateral impressions long, shallowly impressed, the outer 

 very short, more sharply impressed and bounded externally by a 

 small longitudinal ridge not extending quite to the hind angles; 

 elytra oblong, parallel, the sides barely at all arcuate, one-half longer 

 than wide, subcircularly rounded at tip, the humeri dentiform; 

 surface very depressed, broadly and feebly declivous laterally, the 

 striae rather strong, very deeply impressed, finely punctate, the 

 intervals all strongly convex, not at all crenated by the punctures, 

 which are fine and at the bottom of the striae; hind tarsi short, not- 

 ably stout, the joints as in the preceding but shorter and broader; 

 inner tibial crenulation of the male obtusely rounded but distinct. 

 Length (cT) 17.3-18.0 mm.; width 6.3-6.8 mm. California (Lake 



Tahoe) tarsalis Lee. 



Form much less elongate, similar in coloration and polished lustre; head 

 not quite two-thirds as wide as the prothorax, the epistoma, labrum 

 and antennae nearly as in tarsalis, except that the antennae are 

 scarcely at all paler at base; prothorax nearly a fourth wider than 

 long, formed throughout nearly as in the preceding; elytra much 

 shorter and relatively broader, two-fifths longer than wide and more 

 than a fourth wider than the prothorax, the parallel sides more 

 arcuate, the surface rather less depressed, less gradually declivous 

 toward the broadly concave margins; striae strong, very deeply 

 impressed, finely but strongly punctate, the punctures feebly cre- 

 nating the very convex intervals; tarsi almost similar, the crenelures 

 of the tibiae obsolete in the female as usual. Length ( 9 ) 17.0 mm.; 



width 6.7 mm. California (Big Trees) sequoiarum n. sp. 



5 Elytra equal in width to the prothorax or but just visibly wider. .6 



Elytra more oval, at the middle very evidently wider than the prothorax . 8 



6 Elytra with distinct violaceous lustre, black, strongly shining, elongate, 



parallel, feebly convex; head moderate, only three-fifths as wide as the 



prothorax, the anterior impressions rather fine, arcuate, the epistoma 



and labrum barely visibly sinuate, the latter, as well as the palpi 



and antennae except sometimes basally, obscure to paler testaceous; 



prothorax about as long as wide, broadly rounded at the sides, 



feebly, obliquely and subsinuously narrowing posteriorly, the base 



nearly five-sixths the maximum width, broadly sinuate medially, 



margined laterally, the angles sharp but rather more than right, 



the inner of the lateral impressions strong, long and straight, the
