THE CANADIAN ENTOMOLOGIST. 109 



This is extremely similar to the species last described, from which it prin- 

 cipally differs in having the legs of the colour of dark pitch, with the excep- 

 tion of the hands or anterior tarsi, which are rufous : the sides of the ventral 

 segments of the abdomen also appear less conspicuously punctured. 



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

 collis, Lee, in which case the name will not have preference, as the descrir," 

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

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

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

 latior, Kirby. 



45. Curtonotus brevilabris, Kirby. — Length of body 4£ lines. A 

 single specimen taken in lat. 65°. 



[3G.] 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, Kirby. — 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, a!l rufous ; nose 

 at the anterior margin has an obtuse-angular sinus; frontal impressions pane- 

 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, Soy. — 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 5£ lines. One specimen only taken. 



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

 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
