492 TRANSACTIONS OF THE 



basal line ; elytra black, striae reticulated by smaller transverse 

 lines, which, near the base, are much more deeply impressed, so 

 as almost to granulate the interstitial lines ; striae fifteen, trans- 

 verse lines very numerous, fourth, eighth, and twelfth interstitial 

 lines with several equal, equidistant, dilated orbicular, impressed, 

 golden dots, and a solitary one near the scutel, exterior marginal 

 groove greenish ; pectus each side with minute crowded punc- 

 tures ; sternum impunctured ; postpectus each side, and each side 

 of the abdomen with rather larger punctures. 



I was formerly misled respecting this insect by that portion of 

 the specific description of Fabricius which ascribes to it an apte- 

 rous character. In this error I was corrected by Professor 

 Wiedemann of Kiel, who assures me that Fabricius was mistaken, 

 and that his species is certainly winged. 



CAKABUS Lin. Latr. 

 Anterior tibiae entire ; elytra entire ; exterior maxillary and 

 labial palpi subtriangular, dilated ; mandibles not elongated, 

 robust; labrum short, transverse, bilobate ; labium profoundly 

 emarginate and with a central tooth; antennas, second joint half 

 as long as the next ; thorax subcordate, emarginate behind ; ab-

1. C. STLVosus. — Apterous, black; thorax and elytra mar- 

 gined with violaceous, the latter witji a triple series of excavated

Carabus si'v^.sus Melsh. Catal. 



Body black, glabrous ; [76] antennae brownish towards the 

 tips; palpi, terminal joint dilated ; thorax margined, margin vio- 

 laceous, gradually more recurved to the posterior angles, very ob- 

 tusely rounded, slightly extending backwards beyond the basal 

 line, base depressed and with the lateral margin somewhat scabrous, 

 dorsal line obsolete, basal lines wanting ; elytra black, margin 

 violaceous, disk nearly smooth with about thirty striae of minute 

 impressed punctures and three distant series of remote excavated 

 ones. 



All the species of this genus that I have seen, as well as those 

 of Procrustes, Calosoma, &c., have the tibiae of the second pair
