ClCINDELIDyE AND CARABID^ 1 05 



two joints grooved externally. Length (cf 9 ) 14.0-14.6 mm.; 

 width 5.4-5.8 mm. California (Anderson Valley, Mendocino Co.). 



Four examples breviusculus n. sp. 



A Similar except that the body is a little larger and a trifle less ab- 

 breviated, with the elytra a little more shining, more distinctly 

 violaceous and with rather less convex intervals; differing princi- 

 pally, however, in having the sides of the prothorax posteriorly 

 simply oblique and virtually straight, not sinuate, the hind tarsi, 

 also, are a little longer. Length (9) 15.5 mm.; width 5.9 mm. 

 California (Sonoma Co.), Koebele mimus n. subsp. 



Elytra more elongate, deeply striate, with very convex shining intervals 

 (cf ), or a little shorter, opaculate, with finer and feebler striae and 

 less convex intervals (9) n 



li Form elongate, very moderately convex, shining, black, the elytra 

 distinctly violaceous; head rather large, fully three-fourths as wide 

 as the prothorax, the anterior impressions deep and conspicuous, 

 separated by barely a third more than either from the sides, the 

 epistoma and labrum relatively narrower than in the preceding, both 

 feebly sinuate, the latter subangularly; antennae nearly as in the 

 preceding; prothorax large, subquadrate, the sides broadly rounded, 

 with very distinct and broad crenelures throughout, gradually very 

 feebly converging and scarcely at all sinuate posteriorly, the angles 

 rather more than right and blunt; surface with obvious transversely 

 wavy subrugulose lines, the impressions as in the preceding; elytra 

 (cf ) fully three-fifths longer than wide and scarcely visibly wider than 

 the prothorax, parallel, with broadly arcuate sides, the striae deep, 

 impunctate, the intervals all convex, the micro-reticulation evident 

 but shining and, besides, with numerous feeble short transverse 

 irregular indentations; hind tibiae (cf ) with broad rounded internal 

 crenelures in apical two-thirds, the tarsi black, rather slender. 

 Length (cf) 17.0 mm.; width 5.8 mm. Oregon (Clackamas Co.). 



crenicollis Lee. 



Form almost similarly elongate but more ventricose, or with smaller 

 head and prothorax; male strongly shining throughout, the female 

 with shorter and broader, dull and less deeply striate elytra; head 

 not so large as in crenicollis and with the anterior impressions sepa- 

 rated by about one-half more than either from the sides, the epi- 

 stoma and labrum nearly similar, the mandibles strongly, arcuately 

 hooked at tip, the latter very acute; antennae nearly similar; pro- 

 thorax almost as long as wide, the sides nearly even and much more 

 arcuate, distinctly converging and broadly sinuate basally, the angles 

 but little more than right and rather sharp; surface with the trans- 

 verse wavy lines indistinct, the impressions nearly as in brevius- 

 culus; elytra (cf ) three-fifths longer than wide and a fourth wider 

 than the prothorax, shining, with deep impunctate striae and very 

 convex intervals, or ( 9 ) rather less than one-half longer than wide, 

 fully a third wider than the prothorax, opaque, with finer, less 

 impressed striae and flatter intervals, also decidedly wider behind 

 the middle than at base, this being but slightly apparent in the male; 

 scutellar stria similar; tarsi slender, the hind tibiae only very ob-
