basal fovese deep and perforate ; intra-humeral impression large, evanescent 

 slightly before the middle. Abdomen rather shorter and narrower than the 

 elytra, very convex, the basal carinas small and separated by less than J^ of 

 the discal width. Legs of the usual length, the femora only moderately in- 

 flated ; tarsi slender throughout. Length 1.75 mm. ; width 0.65 mm. 



Penns3'lvania (Westmoreland Co.). 



This is one of the more interesting of the numerous important 

 discoveries of Mr. P. Jerome Schmitt, and is dedicated to him 

 with the liveliest appreciation of the continual increase in knowl- 

 edge of our microcoleoptera due to his skillful and patient re- 

 searches in the mountains of Pennsylvania, the treasures of which 

 are only beginning to be unfolded. The single example before 

 me is a male, with, however, no special secondary marks other 

 than those described, the last ventral and pygidium even, being 

 perfectly simple and unmodified. The species may be placed 

 near striatus in our lists. 



ARIANOPS Bndl. 



The two species of this remarkable inquilinous genus before 

 me may be readily distinguished as follows : — 



Pubescence dense; prothorax shorter than wide, more inflated anteriorly, and 

 much more than % as wide as the elytra, the latter distinctly longer than 

 the prothorax, with the sutural impression feeble throughout. 9 Penn- 

 sylvania aiiil>lyopoiiica Bndl. 



Pubescence sparse, more erect and much longer; prothorax longer than wide, 

 less inflated anteriorly, and not more than % as wide as the elytra, the 

 latter not evidently longer than the prothorax, much shorter and more 

 transverse, with the sides more arcuate and divergent, the suture strongly 

 depressed posteriorly. J Carolinas plectrops n. sp. 



As far as known the genus is confined to the Appalachian, 

 Mountain system, where it represents the European Amaurops. 



A. plectrops. — Moderately slender, strongly convex, highly polished, 

 impunctate and uniform dark rufo-testaceous throughout, the hind body 

 elongate-oblong and moderately stout; pubescence long, suberect and somewhat 

 sparse. Head longer than wide, about equal in width and length to the pro- 

 thorax, semicircularly rounded behind the erect, compressed triangular spicules 

 representing the eyes, the spicules each continued forward in a fine carina at 

 the lower margin of the antennal cavities to the base of the mandibles; upper 

 surface convex, with two deep nude fovese near basal fourth, separated by 

 about % of the maximum width, each at the posterior limit of a broad and 

 moderately deep sulcus, the two uniting anteriorly in a large gradually 

 declivous smooth and polished frontal depression between the antennal prom-
