Carabus seriatus Wiedemann, Germ. Magazin, 4, 109. 



Eussian America and Oregon, abundant. This species long ago described by Fabricius, 

 probably from the collection of Captain Cook's voyage, has been lost sight of in modern times, 

 or rather has been made known under other names ; the insect described by Fabricius was in 

 Sir Joseph Banks' collection, and the figure given by Olivier is quite recognizable. 



C. oregonensis, cyaneo-niger, thorace fere opaco, latitudine vix breviore, minus convexo, 

 utrinque angustato, lateribus rotundatis, angulis posticis modice productis, apice rotundatis, 

 lateribus pone medium subreflexis, elytris thorace fere duplo latioribus, subtiliter striolato- 

 punctatis, foveisque minus profundis serie triplici impressis. Long. "85. 



Lee. Proc. Acad. Nat. Sc. 7, 16. 



One male from Prairie Paso ; Dr. Cooper. Closely related to C. taedatus, but the thorax is 

 proportionally much smaller and narrower, and much more densely and finely rugose ; the 

 rugae of the head are also smaller, and the impressions less deep ; the striae and foveae of the 

 elytra are less deeply marked. 



Calosoma Fabr. 



C calidum Fabr. A specimen collected at Steilacoom, by George Gibbs, esq., cannot, after 

 much examination, be separated from this common species. It is rather narrower than any 

 other specimen I have seen, and the coppery foveae of the elytra are larger and less numerous. 



C. cancellaium, nigro-aeneum, crassiusculum, thorace latitudine plus duplo breviore, dense 

 intricato-rugoso et punctato, basi utrinque late foveato, lateribus latins rotundatis pone medium 

 modice reflexis, angulis posticis paulo productis rotundatis, elytris oblongis, thorace parum 

 latioribus, saepe virescentibus, seriatim punctatis, transversim rugosis, foveisque aeneis serie 

 triplici impressis, interstitiis catenatim paulo elevatis, tibiis intermediis rectis. Long. "8.

Eschscholtz, Zool. Atlas, 5, 23 : Mann. Bull. Mosc. 1843. 



Calosoma aenescens Lee. Proc. Acad. Nat. Sc. 7, 16. 



Fort Vancouver, Dr. Cooper ; Sacramento, California, Mr. Wittick. Shorter and less convex 

 than C. calidum, approaching in form some species of Callisthenes ; the thorax is hardly nar- 

 rowed behind, and the posterior angles are distinctly, though broadly produced. The wings 

 are well developed, and the other joints of the antennae are equably pubescent. The intervals 

 between the rows of punctures of the elytra are marked with a few transverse striae ; the spaces 

 between the impressed foveae are distinctly elevated, and smoother than the other parts of the 

 elytra. 



The specimens collected by Dr. Cooper, in Oregon, differ from those found in California, by 

 the less distinct green tinge of the elytra, which are also less densely rugous ; on this account 

 I was disposed to regard them as indicating a species different from that of Eschscholtz, but 

 the subsequent receipt of two specimens from California, which, with many other valuable species, 

 were presented to me by Mr. S. S. Eathvon, enables me now to pronounce these differences as
