40. Harpalus ellipsis Lee. 



41. " basilaris Kii-b. N. to Canada. [At Canon City Mr. Wickham 



found II. oblitus, H. lusirans and H. basilaris.] 

 i2. Stenolophus conjunctus Say. N. to Canada. 



43. Tachycellus nigrinus Dej. N. to Canada. 



44. " badiipennis Hald. 



Carabus maeander, Notiophilus sibiricus and Amara i^iterstitialis are boreal 

 and Asiatic, wiiile Amara erratica and Blechrus nigrinus are boreal 

 and proi)alily circu in polar. 



Some species o? Anisodactylus would probably be found on further search, 

 though so far as I can gather, Colorado is poor in this genus. I found 

 A. nigrita Dej. in Cottonwood Gulch, Saguache County; this is high 

 up on the western slope of the Sangre de (]risto Range. 



At Red Cliff, which is mid-alpine, though over one hundred miles from 

 Wet Mountain Valley and on the Pacific slope, Mr. Wickham found 

 fifteen Carabidse, of which the following eleven are wanting in our 

 district : Calathus ingratus, Bembidium planatum, B. transversale, B. 

 paludosum var. lacustre, B. maeklini, B. fagax, B. quadrulum, Amara 

 impuncticollis, Pterostichus protractus, P. hudsonicus, P. mutus. 



At Salida, which is lower mid-alpine on the Atlantic slope, Mr. Wickham 

 found thirteen Carabidse, of which the following eight are wanting 

 in our district : Calosoma obsoletum, Nothopus sabroides, Harpalus oblitus, 

 H. pennsylvanicus var. compar, Amara gibba, Platynus placidus, P. er- 

 rans, Pterostichus orinomum. These comparisons indicate more differ- 

 ence between the localities than I had quite expected, but perhaps 

 the distinctions would appear less if fuller information were obtained. 



HALIPLID^.

DYTISCID^.

53. " obliteratus Lee. Originally described from Fort Laramie. [At 



Canon City Mr. Wickhaic found A. lugens.] 



54. Rhantus binotatus Harr. N. to Canada. 



Deronectes catascopium, if considered specifically identical with D. griseo- 

 striatus DeG., is not only boreal in America, but extends to northern 

 Europe and Siberia.
