II SOME OBSERVATIONS ON THE CARABID^E 

 INCLUDING A NEW SUBFAMILY. 



A few more or less interesting new Carabid species and subspecies 

 have been in my collection for some time, awaiting a convenient 

 opportunity for publication. It would be better to have had them 

 appear in the course of systematic work, but as the groups to which 

 they pertain have in most instances been studied monographically 

 in comparatively recent times, it will be easy to make the necessary 

 interpolations. 



Subfamily CARABINE. 

 Tribe CYCHRINI. 



The singularly isolated habitus of the species in this section of 

 the Carabidse, as well as their frequent rich metallic coloring, has 

 caused them to receive a large amount of attention from collectors 

 of the Coleoptera, but taxonomically they are rather difficult to 

 deal with. The following seem to be some rather evident novelties 

 in this tribe: 



Irichroa aeneicollis ssp. tricarinata nov. Form nearly as in cencicollis 

 but rather narrower and more elongate, black, without metallic reflection 

 at any part, except a very feeble greenish glint on the pronotum; head 

 and antennae nearly similar; prothorax similar in form and size, except 

 that the sides are not sharply angulate but prominently rounded, the 

 surface more rugulose transversely, the longitudinal impressions a little 

 more acutely and deeply impressed and the basal margin relatively 

 narrower; elytra nearly similar but rather more elongate and less convex, 

 the striae with even coarser and more crowded punctures and with inter- 

 vals 4-8-12 elevated, becoming feebly cariniform basally; tarsi nearly 

 similar. Length (cf) 18.5 mm.; width 7.7. mm. North Carolina (Blue 

 Ridge Mts.), Beutenmiiller. 



The geographical habitat is different from that of (eneicollis, 

 which has occurred so far only on the Black and Balsam Mts. of 

 North Carolina and Tennessee; it is a distinct species and by no 

 means a subspecies or variety of andrewsi. 



Sphaeroderus lecontei ssp. diffractus nov. -Similar in general form 

 and habitus to lecontei but more slender and very much smaller, shining,
