[LeConte (Joe. cit. p. 356) states that this is " probably a variety of A. lati- 

 coUis, Lee, in which case the name will not have preference, as the descrip- 

 tion must be considered worthless, and moreover must be considered aa 

 erroneously separated from A. convexiusctila, Kirby." He makes the same 

 remarks also upon the two following species : C. brevilnhris, Kirby, and C. 

 latior, Kirby.] 



45. CuRTONOTUft BREViLABRis, Kirhy. — Length of body 4J lines. A 

 single specimen taken in lat. 65°. 



[36.] Like the preceding species, but smaller : the upper lip is blacker, 

 not half so long and slightly emarginate : the elytra are dark, and the legs 

 pale chestnut; the furrows of the former are less conspicuously punctured; 

 the frontal impressions likewise are longer and connected by a slighter 

 furrow. 



47. CuRTONOTUS LATIOR, Kirhy. — Length of the body 5 lines. One 

 specimen only taken. 



This species has a good deal the aspect of Bradytus apricarius, but it is a 

 larger insect and rather wider in proportion, and the bifid intermediate tooth 

 of the lower lip proves that it is a true Curtonotus. Body piceous, above 

 bronzed. Upper lip, palpi, antennae, side-covers, and legs, all rufous; nose 

 at the anterior margin has an obtuse-angular sinus ; front^al impressions punc- 

 tiform, connected by a slightly-drawn line or furrow : prothorax wider than 

 long, the lateral margins forming a segment of a circle without any posterior 

 constriction ; at the base the prothorax is depressed, the basilar impressions 

 are bisulcate, the inner furrow being the longest : furrows of the elytra punc- 

 tured. 



48. PcECiLUS [Pterostichus] lucublandus. Say. — Many specimens 

 taken in lat. 54°. [Excessively common in Canada; for description vide 

 Say's Ent. Works, ii. 478.] 



[37] 49. PcECiLus [Pterostichus] castanipes, Kirby. — Length of 

 body 5J lines. One specimen only taken. 



This species differs from variety D of P. lucublandus ("entirely blacky 

 with the sides of the prothorax impunctured, elytra violet"), which it much 

 resembles, it being entirely black; in having slighter basilar impressions, less 

 distinctly punctured : it has likewise only three punctiform impressions on 

 the elytra, the granular reticulations of the substance of which are also more 

 easily discovered. [Considered to be merely a variety of F. lucublandus by 

 LeConte.] 



50. PcECiLus [Pterostichus] chalcites, Say,— Only a single specimen 

 taken. 



[Not uncommon in Canada; for description vide Say's Ent. Works 

 ii. 479.]
