50. Amara discors, Kirby. — Length of body 4 lines. One specimen 

 only taken. 



This species has somewhat the aspect of a Ilarpalus^ but it exhibits the true 

 characters of Amara : it appears to bo related to A. discrcpans, Stephens. 

 Body dark piceous, glossy. (Jpper-lip, palpi, mouth and antennse ferniginouB : 

 prothorax a little narrowed behind ; bead of the lateral margin rufous j basilar 

 impressions rather slight: elytra less glossy than the rest of the body, the 

 infinitely minute and numerous granular reticulations of their substance being 

 more conspicuous than usual ; the furrows of the elytra from minute punc- 

 tures exhibit a slight appearance of crenulations : legs pale chestnut. [Un- 

 known to Dr. LeConte j the student of the AmarsR is referred to his paper 

 on this genus in the Pro. Acad. Nat. Sci. Phil., June 1855, p. 346, for much 

 valuable matter and fuller descriptions.] 



[40] 57. Harpalus pleuriticus, Klrhj. — Taken frequently in lat. 54®. 

 [For description vide Mr. Sprague's Carabidos, Can. Entom. ii. p. 96. 

 Taken in Ontario and, according to Pr. LeConte, in Minnesota and Winnipeg.] 



58. Harpalus ^ xSILAris, Kirht/. — Length of body 4 lines. Taken with 

 the preceding, and in equal numbers. 



This species differs from the preceding, which it nearly resemhles, in having 

 the two first joints of antennse yellow, and the remainder dusky; in having 

 the prothorax still wider in proportion to its length, with its posterior angles 

 more acute and impunctured, and with narrower basilar impressions also 

 without punctures; its lateral margin is also black and le.ss prominent: the 

 side-covers of the elytra are likewise black : the legs are dark-piceous, with 

 yellowish-red trochanters. In other respects it resembles IT. pleuritictu. 

 [Unknown to Dr. LeConte.] 



[41] 59. Harpalus oohropus, Kirbi/. — Length of body 3J lines. [No 

 locality stated.] 



This comes very near H. pleuritieus, but is considerably smaller; the 

 antennae are longer ; the prothorax is impunctured at the base, its basilar 

 impressions are linear; the side-covers of the elytra are chesnut; and its 

 thighs are more robust in proportion. [Unknown to Dr. LeConte ; supposed 

 by him to be perhaps IT. desertus, Lee.] 



60. Harpulus interpunctatus, Kirly. — Plate vii. fig. 8. — Length of 

 body 5 J lines. Many taken in lat. 54°. 



Body proportionally longer than in the antecedent species, black, glossy, 



not depressed. Head triangular, with a pair of confluent red dots, visible 



only in the son, between the eyes ; antennae shorter than the prothorax, with
