ClCINDELID/E AND CARABID.E 137 



try, are very remarkable and one of these was named Pterostichus 

 manhattanis by the writer many years ago; I am convinced that 

 it is a synonym of that species, however, so far as evidence at hand 

 is interpretable and as stated by Horn, but I think that that form 

 which is so abundant in Utah dark greenish-black, a little smaller 

 and shorter than lucublandus and apparently named fraternus by 

 Say is a valid species; the prothorax is always much shorter and 

 more transverse than in lucublandus. These species will constitute 

 a well denned group of Pcecilus and in some ways, such as the struc- 

 ture of the pronotum, come between Abacidus and the next group, 

 probably of more typical Pcecihis, although the three basal joints 

 of the antennae are similarly carinate. 



Chalcites group. 



Pcecihis is now generally accorded generic weight, so that the 

 original name chalcites, given by Say to the species subsequently 

 named sayi by Brulle, becomes valid. Two unnamed species have 

 recently been received as follows : 



Poecilus snowi n. sp. Elongate-suboval, moderately convex, shining, 

 very dark violaceous-blue to obscure green in color; under surface and 

 legs deep black; head small, half as wide as the prothorax (cf), a little 

 less (9), the impressions deep, parallel, broadly concave and separated 

 by twice the distance of either from the sides; epistoma and labrum trun- 

 cate; palpi black; antennae black, the two basal joints largely testaceous, 

 the carina of the three basal joints strong; prothorax a sixth to fifth 

 wider than long, the sides evenly arcuate from apex to base, more con- 

 verging anteriorly, the basal angles obtuse but minutely and denticularly 

 prominent; base a fourth wider than the apex, fully seven-eighths the 

 maximum width, margined except medially and transverse; surface 

 convex, finely and abruptly reflexed at the sides throughout, the stria 

 rather strong, subentire, the inner impression deep, sharply marked at 

 the bottom and linear, the outer elongate-oval, very near the base, both 

 impunctate; elytra oblong-oval, three-fifths to two-thirds longer than 

 wide, rather flattened inwardly, the sides parallel, feebly arcuate, the 

 apex subangularly rounded, scarcely a fourth wider than the prothorax, 

 the striae moderate, finely punctate, the scutellar long, the intervals 

 only very feebly convex. Length (cf 9 ) 11.7-13.5 mm.; width 4.3-5.0 

 mm. Arizona (San Bernardino Ranch, Cochise Co.), F. H. Snow. 



Allied to texanus Lee., but differing in its narrower and more 

 elongate form, much more elongate prothorax, darker and less 

 brightly metallic coloration, less evident abdominal punctures and 

 somewhat longer antennae and hind tarsi. From cyaneus it differs
