the scape and last joint of the palpi rufous: prothorax subquadrangular; 

 anterior angles rounded ; dorsal channel drawn from the apex to the hase 

 punctured especially posteriorly, disk impunctured, transversely wrinkled ; 

 bsBilar impressions shallow ; lateral margin dilated posteriorly ; elytra rather 

 deeply furrowed, furrows impunctured, interstices convex, very minutely but 

 not thickly punctured : the four anterior tarsi of the male are furnished with 

 a thick brush of vesicles, not arranged in a double series, as in other species 

 of this genus. [Placed, with a mark of interrogation, in LeConte's List, as 

 a synonym of Anmdactylus mclanopus, Hald., a specica taken in Canada.] 



[42] 61. Harpalus longior, Kirht/ — Length of body 5^ to 7 J lines. 

 Two specimens taken, the largest in lat. 5-4°. 



Body black. Upper-lip piceous ; antennae, palpi and legs reddish -tawny, 

 the first longer than the prothorax ; the nose terminates anteriorly in a red- 

 dish membrane or rhinarium : prothorax quadrangular with all the angles 

 rounded, rather longer than wide ; dorsal channel anteriorly abbreviated , 

 lateral margin minutely punctured, much dcpresser], especially at the posterior 

 angles ; basilar impressions double, shallow, and minutely punctured j elytra 

 very little glossed, more than twice the length of the prothorax, furrows 

 impunctured with convex interstices, the lateral ones with some scattered very 

 minute punctures ; the vesicles on the sole of the four anterior tarsi of the 

 male are arranged as in the other Ilarpali. 



Both the specimens taken in the expedition are males, or I should have 

 supposed the unusual diflFerence in their size was sexual : probably the small 

 one was taken in a higher latitude. [Unknown to Dr. LeConte ; thought by 

 him to be perhaps //. vagans, Lee.] 



62. Harpalus laticollis, Kirb^. — Length of body 5 J lines. A single 

 specimen taken. 



This insect very closely resembles II. interpundatus ; it differs principally 

 in having a rather wider prothorax with all the angles rounded, with the 

 dorsal channel abbreviated anteriorly, and with only the base very indistinctly 

 punctured j the interstices of the furrows of the elytra are also without punc- 

 tures, and there is a single punctiform impression in the usual situation adja- 

 cent to the second furrow. [Previously described m Anisodactylus nigerrimus 

 by Dejean.] 



[43] 63. Harpalus [Anisodactylus] Carbonarius, Say.—T^o speci- 

 mens taken in lat. 54°. [Taken also in Canada; for description vide Say's 

 Ent. Works, ii. p. 460.] 



64. Harpalus rotundicollis, Kirhy. — Length of body 5 J lines. Two 

 specimens taken. 



Body brownish, black, glossy. Antenna length of the prothorax, as well 

 as tha tip of the palpi, rufous : prothorax wider than long, with rounded
