little contracted behind, base nearly equal to tbe base of the ely- 

 tra, dorsal line profoundly and equally impressed, anterior 

 transverse line more profoundly impressed, confluent with 

 the marginal groove at the anterior angles, basal lines strongly 

 impressed, excurved, and distinctly confluent with the marginal 

 groove behind the angles, lateral edge excurved at the hind 

 angles, posterior angles acute ; elytra, stride impunctured, inter- 

 stitial lines very convex, third with three remote punctures, one 

 near the base, one near the middle, and one towards the tip ; feet 

 black; tarsi piceous. 



[This is a species of Lopho(jlossus Lee, and is most probably 

 the one described by Dejean as Feronia complanato. — Leg.] 



16. F. MUTA. — Black ; thorax punctured each side at base ; 

 elytra with obsoletely punctured strise. 



Length half an inch. 



Carabus adoxus Melsh. Catal. 



Body glabrous, black ; antennse ferruginous towards tip, joints 

 attenuated towards their bases ; palpi piceous ; thorax in the 

 middle as broad as the elytra, gradually a little contracted to the 

 base, where it is very slightly excurved ; base somewhat de- 

 pressed, and distinctly punctured each side, dorsal line distinctly 

 continued to the base ; [ 45] elytra, striae obsoletely punctured, 

 interstitial lines convex, third one with a puncture at the base, 

 one in the middle, and one near the tip ; feet black ; tibiae and 

 tarsi piceous ; postpeetus punctured each side. 



Diflfers from adoxus, to which it is closely allied, in having 

 less robust antennae, vestiges of punctures in the elytral striae, 

 the thorax more rounded and less excurved at the posterior 

 angles, and the dorsal line not abbreviated behind. 



[Also described subsequently as Feronia morosa Dej., and 

 Omaseus picicornis Kirby . — Leg.] 



17. F. SUBMARGINATA. — Blaokish, glabrous, all beneath pi- 

 ceous ; thorax with a depressed margin, the edge reflected, base 

 each side, and elytral striae punctured. 



Length half an inch. 



Antennae and palpi deep piceous ; labrum truncate, piceous ; 

 thorax in the middle as broad as the elytra, base punctured,
