14:4: TIIE CANADIAN ENTOMOLOGIST. 



This comes very near II pleuriiicus, 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 II. desertus, Lee] 



69. IIarpulus interpunctatus, Kitby. — Plate vii. fig. 8. — Length of 

 body 5 \ 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 sun, between the eyes; antennas shorter than the prothorax, with 

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

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

 punctured especially posteriorly, disk impunctured, transversely wrinkled ; 

 basilar 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 Anisodactylus melanopus, Hald., a species taken in Canada.] 



[43] 61. Harpalus longior, Eirby — Length of body 5£ to 7J lines. 

 Two specimens taken, the largest in lat. 54°. 



Eody black. Upper-lip piceous ; antennse, palpi and legs reddish-tawuy> 

 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 depressed, especially at the posterior 

 angles ; basilar impressions double, shallow, and minutely punctured ; 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 Harpali. 



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

 supposed the unusual difference 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 II vagans, Lee] 



62. Harpalus laticollis, Kirby. — Length of body 5 \ lines. A single 

 epecimen taken. 



This insect very closely resembles II. interpunctatus ; 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
