second and third joints pubescent. Gense beneath very convex or mammillate, 

 the gula strongly impressed slightly narrowed in front and behind. Eyes 

 rather small, strongly projecting, coarsely facetted and pubescent. Antennae 

 equal in length to the head and thorax united, somewhat slender, gradually 

 thickened, first joint large, oval, incrassate, second slightly shorter and less 

 incrassate, third more slender, elongate-conic, four to seven subglobular, eight 

 wider and slightly transverse, nine and ten quadrate as wide as eight and 

 eleven, eleven longer than wide, apex acutely rounded. 



Prothorax longer than wide, subcylindric, posterior margin slightly wider 

 than the anterior, sides subangulate, slightly compressed in front and indi- 

 stinctly toothed a little in front of the middle, side margin much depressed, 

 descending to the angulation from the anterior and -posterior margins, an indi- 

 stinct impression on the median line before the middle. 



Scutellum somewhat large, acutely triangular, with a few coarse punc- 

 tures. 



Elytra with the shoulders rounded, not very prominent, posterior-external 

 angles widely rounded, posterior margin slightly retracted at the suture. 



Tibiae and tarsi pubescent and ciliate, the first four joints of the posterior 

 tarsi subequal, fifth joint equal in length to the three preceding. Length 2.75 

 mm., breadth i mm. 



Type 5 in the collection of the author, paratype.J i" the collection

Collected at Roselle Park, Union Co., N. J., by Mr. C. W. Leng. 



The species of Borcaphilns are found in leaves and moss in damp 

 localities. The American specimens were found with Stemis. 



Eight species of Boreaphilus are listed in the Coleopterorum Cata- 

 logus of Junk and Schenkling (Pars 19, 1910, p. 84), of these hen- 

 ningianus, sahlbergi and velox have been mentioned; astur Sharp 

 from Asturia is probably allied to velox, having rather short and 

 stout antennae (An. Soc. Esp., I, 1872, p. 266) ; carinthiacus Gangl. 

 is a winged form also allied to z'elox (Gangl. Kaf. Mitteleur., II, 1895, 

 p. 700) ; japonicus Sharp from Japan resembles henningianus , but 

 has a smaller head and longer elytra, the latter would distinguish it 

 from amcricanus ; lewisianus Sharp, also from Japan, is distinguished 

 from henningianus by its broader thorax and longer antennal joints — 

 all the joints being longer than broad (Trans. Ent. Soc. Lond., 1874, 

 p. 96). The description of nordcnskioeldi Makl. (Oefv. Finsk. Vet. 

 Soc. Forh., XIX, 1876-77, p. 25) could not be consulted. B. volans 

 J. Sahib., described after the publication of the Coleopterorum Cata- 

 logus, Pars 19, is a winged species resembling velox, but having more 

 slender antennce (Medd. Soc. Fauna. Fenn., 37, p. 47, Nov., 1910). 

 These species are from Eastern Siberia and Finland respectively.
