126 MEMOIRS ON THE COLEOPTERA 



tinctly less than twice as long as the prothorax and barely percep- 

 tibly wider, slightly more evidently in the female, the striae strong, 

 deep, impunctate, those on the flanks even coarser and deeper than 

 the others but more approximate; intervals convex, feebly so 

 suturad, the lateral line of foveae widely interrupted; scutellar 

 stria long, deep and distinct; humeral denticle small but strong; 

 legs moderate. Length (d 71 9 ) 8.0-8.5 mm.; width 2.5-2.8 mm. 



California (Sta. Cruz Mts.) crucialis n. sp. 



Form very slender, parallel, piceous-brown to obscure rufous, shining 

 throughout; head small though relatively larger than in the pre- 

 ceding, the impressions similar; eyes a little smaller and still less 

 convex; prothorax as long as wide ( 9 ) or somewhat elongate (cf), 

 the base and apex equal; sides only very feebly arcuate, a little more 

 rounding apically, very feebly converging, becoming very gradually 

 straight posteriorly to the minutely prominent angles; base much 

 more feebly margined than in the preceding and extremely near the 

 maximum width in both sexes; stria and impressions nearly similar 

 but with the lateral margin still distinctly narrower, excessively fine; 

 elytra almost similar in form and striation, except that the striae 

 are a little finer, especially on the flanks. Length (c? 9 ) 6.7-8.0 

 mm. ; width 2.0-2.25 mm. California (San Francisco and Napa Co.). 

 [linearis Lee.] angustus Dej. 



Caligans Horn, which the author states (Tr. Am. Ent. Soc., 

 1891, p. 33) should be included in this group, is said to be still 

 more slender and elongate than angustus, with very small eyes, 

 with single basal thoracic impressions and without trace of the 

 basal marginal line so conspicuous in angustus and especially in 

 crucialis; the elytral striae are said to be obsoletely punctate, 

 the length 10-11 mm., and the type locality Sylvania, Cal. The 

 hind trochanters of the male in inanis are two-thirds as long as 

 the femur and gradually attenuated to a very fine point; in the 

 male of angustus they are more oval, with the apex rather narrowly 

 blunt and are a little more than half as long as the femur; in the 

 male of crucialis they are distinctly less than half as long as the 

 femur, still more oval and more obtuse at tip than in angustus. 



Elongatus, of Schaeffer, apparently belongs to this group and is 

 probably closely allied to inanis, if not identical. 



Group VI longicollis Lee. 



A special group seems advisable for a number of species, among 

 the most minute of the first division of Pterostichus in the LeContean 

 sense. They are stouter in form than those of the preceding 

 group and more ventricose as a rule, have but a single subbasal
