American Caraboidea 191 



viated; foveae linear, coarse, deeply impressed and punctulate in basal 

 two-fifths; surface thence to the sides convex, with a coarse intermediate 

 punctate groove in basal fourth; elytra one-half longer than wide to a 

 little less, scarcely a third wider than the prothorax, the arcuate sides a 

 little more rounded basally, the subapical sinus feeble; edges rufous 

 posteriorly; striae fine but rather deeply impressed, almost smooth or 

 feebly punctate externally; intervals very feebly convex, the third with 

 two or three punctures adjacent to the second stria, the first a little 

 before the middle; scutellar stria very short, the puncture distinct; 

 anterior male tarsi with the first three joints rather strongly dilated. 

 Length (cf) 7.3 mm.; width 2.75-2.8 mm. British Columbia (Stickine 

 River Cafion), — Wickham. 



Distinguishable by its rather broad and more than usually 

 parallel form and moderate convexity; the thoracic base is feebly 

 sinuate medially, as wide as the apex and not margined laterally.

 The male in this genus seems to be much rarer than the female, 

 and it was only recently, on receiving some additional material 

 from Mr. Loding, that I have been able to observe its tarsal char- 

 acters. In the male the anterior tarsi are very moderately dilated, 

 the under surface of the first three joints having two series, in 

 mutual contact, of elongate white subgelatinous plates, crossed by 

 fine distant transverse lines; this, at least, being the condition in 

 castigata. In the female the first two or three joints of the anterior 

 tarsi are sometimes, but apparently not in all the species, obliquely 

 and acutely prolonged internally at apex. The recognizable 

 taxonomic forms in this genus are more numerous than hitherto 

 supposed, and among the six examples sent from Mobile by Mr. 

 Loding, I am obliged to recognize four, which are given the specific 

 status provisionally and until more abundant material can be 

 obtained. These four forms may be set forth in tabular arrange- 

 ment as follows: 



Elytral striae with feeble but distinct punctures 2 



Elytral striae without obvious punctuation 3 



2 — Anterior tarsi ( 9 ) slender throughout, the basal joints not or very 

 feebly asymmetric. Body of short and rather stout form, polished 

 black, the legs piceo-rufbus, the palpi slender; prothorax shorter, 

 nearly one-half wider than long, the denticle at the sides at the 

 posterior setigerous pore acute, prominent and very near the base, 

 which is about half the maximum width; elytra oblong-oval, very 

 gradually arcuately ogival posteriorly; punctures rather strongly
