ClCINDELID^E AND CARABID/E 163 



Elytral striae very fine and never distinctly punctate 5 



3 Body ferruginous in color. Shining, depressed above, convex beneath; 

 head elongate, three-fifths as wide as the prothorax, the antennae 

 only moderately slender and ( 9 ) not quite half as long as the body, 

 the third joint not quite a third longer than the fourth; prothorax 

 a fifth to sixth longer than wide, widest but little before the middle, 

 the sides parallel and broadly arcuate, gradually converging pos- 

 teriorly, becoming parallel for a short distance before the sharply 

 defined hind angles; base sinuate medially, transverse near the sides, 

 fully as wide as the apex and three-fifths the maximum width; 

 surface feebly convex, sharply but moderately reflexed at the sides, 

 slightly flattened and transversely subrugulose basally, the median 

 stria distinct, impressed, subentire; apical angles very obtusely 

 rounded; elytra oval, twice as long as wide and four-fifths wider 

 than the prothorax, the side margins very strongly reflexed, the 

 striae impressed, coarsely and irregularly punctate, the scutellar 

 long, forming an even continuation of the first stria, the intervals 

 polished and convex, impunctate; apices much prolonged and very 

 acute; legs long and slender; hind tarsi two-thirds as long as the 

 tibiae, the first joint of the anterior apparently with a very faint 

 groove at each side of the upper surface; claws long and slender. 

 Length (9 ) 13.0-14.0 mm.; width 4.3-5.0 mm. New Mexico (Fort 

 Wingate). Three examples nivalis Horn 



Body black in color, picescent beneath, the legs blackish-piceous; body 

 smaller and much more slender, the upper surface polished through- 

 out 4 



4 Form very moderately ventricose; head moderately elongate, three- 

 fourths as wide as the prothorax, the neck rather abruptly formed; 

 antennae brownish-testaceous throughout, slender, not quite half as 

 long as the body, the third joint about one-half longer than the 

 fourth; prothorax oval, widest just visibly before the middle and 

 fully a fourth longer than wide, the sides broadly rounded, sub- 

 parallel, feebly converging anteriorly, more so posteriorly, becoming 

 parallel before the angles, which are barely so much as right and 

 very sharp; base very feebly sinuate, transverse at the sides, three- 

 fifths the maximum width, equal to the apex, which is very feebly 

 sinuate between the very obtusely rounded angles; surface feebly 

 convex, broadly and feebly impressed along the sides, more so basally, 

 the side margins acutely but narrowly reflexed, the median stria fine 

 but deep, subentire: elytra twice as long as wide, scarcely visibly 

 less than twice as wide as the prothorax, oval, the apices obliquely 

 and broadly sinuate, with the tips much produced, dehiscent and 

 very acute; margins strongly reflexed; striae impressed, with rather 

 regular coarsish punctures, the scutellar long, the intervals convex; 

 legs only moderately long; anterior tarsi not grooved dorsally. 

 Length (cf) 12. o mm.; width 3.9 mm. New Mexico (Jemez 

 Springs), John Woodgate umbra n. sp. 



Form slightly more abbreviated; head fully two-thirds as wide as the pro- 

 thorax, the neck more gradually formed than in umbra; antennae nearly 

 similar but rather longer, half as long as the body, the third joint two-
