PTEROSTICHIN.E 343 



sinuate and strongly margined apex; subbasal impression feeble but 

 evident, not deeper near the foveae, which are impressed, the bottom 

 a long fine incised and outwardly arcuate line, curving outwardly 

 at base; lateral carina very fine; elytra elongate-oval, sometimes a 

 little narrower than the prothorax, the striae impressed, finely, not 

 closely punctate, the sixth slightly, the seventh much, finer and less 

 impressed; scutellar stria wholly wanting. Length (cf) 12.3-13.0 

 mm.; width 4.2-4.5 mm. New Mexico (Las Vegas). Three ex- 

 amples ovipennis Lee. 



Elytra never as narrow as the prothorax, the base of which has much 

 more than half the maximum width 4 



4 Elytral striae extremely fine and not impressed, the sixth and seventh 

 barely traceable; intervals flat 5 



Elytral striae distinctly impressed, the intervals more or less convex. . .6 



5 Form rather short and stout, black, shining, the elytra just visibly 

 alutaceous; legs piceous-black; head rather longer than wide, fully 

 two-thirds as wide as the prothorax; antennae black; prothorax not 

 a third wider than long, rather large, the apex sinuate, broadly, 

 strongly margined; foveae with a long inner impressed line, curving 

 outward at base, then forward at some distance from the lateral 

 edge and for less than half the length of the inner sulcus, the carina 

 obsolete; elytra one-half longer than wide, a fourth wider than the 

 prothorax, oval, with the sides rapidly rounding inward at the hu- 

 meri; subapical sinus broad and very shallow; striae with fine, feeble 

 and somewhat irregular punctulation, the scutellar wanting; met- 

 episterna much wider- than long, the epimeron more than half as 

 large as the episternum, as usual in this part of the Pterostichid 

 series; transverse sulcus toward the sides of the first abdominal seg- 

 ment conspicuous. Length (cf ) n.8 mm.; width 4.4 mm. Xew 

 Mexico (Sta. Fe), Miss Greene substriata Lee. 



Form more elongate, black, shining, the elytra feebly alutaceous in the 

 female; under surface and legs black; head barely elongate, nearly 

 three-fourths as wide as the prothorax; eyes well developed, the 

 sulci short, deep and parallel; antennae piceous-black, extending to 

 the thoracic base; prothorax slightly over a third wider than long; 

 apex sinuate but not margined, the usual deep incised line wanting, 

 except toward the sides, the latter less coarsely reflexed than in the 

 preceding, the part between the abrupt constriction and the base 

 straight, diverging and fully a sixth the total length; foveae nearly 

 as in the preceding but deeper; general surface with more evident 

 fine ruguliform lines; elytra three-fourths longer than wide, barely 

 a fifth wider than the prothorax, the arcuate sides more rounded at 

 base; subapical sinus broad and shallow but evident; striae consisting 

 of series of very fine, irregularly and well spaced punctules, the scu- 

 tellar subobsolete; intervals perfectly flat and having a few feeble 

 irregular transverse creases. Length (9) 12.8 mm.; width 4.35 

 mm. Mexico (Colonia Garcia, Sierra Madre Mts., Chihuahua),
