green; the intermediate segments have each a pair of impressions from which 

 a hair emerges. This is most visible in the % . 



I at first regarded this splendid insect as a new species. I thought it, 

 indeed, very near C. Viefiti<jhovu, hut as it did not altogether agree either 

 with Dr. Fischer's figure or description, and was found in another quarter of 

 the glube, 1 regarded it as distinct; but having received from my friend, Mr. 

 Hope, a Kussian specimen of that insect, I find no difference sufficient to 

 constitute a species. In that specimen the marginal gilding uf the prothorax 

 and elytra is greener with v'*carcely any of the ruddy hue of copper which gives 

 such brilliance to the American specimen. 



[A single specimen only of this magnificent beetle was brought to Mr. 

 Kirby in the llichardson collecilon, and no locality is given of its capture; 

 can it have come from Russia, and not from British America? No specimen 

 of it has been taken in this country, so far as we are aware, since the time of 

 that expedition, a period of over oO years. It miglit have been included in 

 the col'ection by some accident — a not infrequent occurrence. I'rof. Croft, 

 for instance, writes us that some years ago he had a collcctiun of moths given 

 to him " collected in or near Toronto," yet among them was a gigantic 

 Chinese Saturnia ! He adds, that on looking ijto Fischer's work he finds 

 the habitat for the insect is '-Eastern Siberia — banks of the Lena."] 



[18] 14. Carabus Ligatus, Knock. — Taken in Canada by Dr. Bigsby" 

 Length of body 7* lines. 



Body black and glossy. Head oblong, impunctured, separated from the 

 neck by a transverse slender curving ridge forming anteriorly a deep sinus ; 

 ridge, defending the base of the antennae, conspicuous; frontal impressions 

 Ion tr, not deep; antenna) not much longer than the prothuvax ; pmthorax 

 nearly square, black slightly bronzed ; sides lightly punctured, lateral margin 

 reiiesed; it is faintly channelled, depressed transversely at the base, with a 

 punctured impression on each side; elytra bronzed, sub-depressed with 

 scarcely any sinus at the apex, lateral margin reficxcd and carinated ; each 

 elytrum with 13 or 14 rows of impressed punctures ; a triple series of oblong 

 discodial elevations; interstices with numerous transverse linear impressions: 

 abdomen underneath smooth with a few minute punctures on the sides. 



The insect here described agrees with Germar's description of Knoch's C. 

 J/'gafux. hut it is doubtful whether it be synonymous with C. carindtus of 

 DeJean. In most respects, indeed, it accords precisely with his description, 

 but the head is not slightly punctured, as he states his specimens to be.
