terior facets less convex than the anterior; anfennae missing in the 

 type; prothorax slightly narrower than the heai, not qaite as long as 

 wide, widest near the apex, the sides rather strongly converging and 

 almost straight to the base, the angles obtnse but scarcely at all blant, 

 the surface broadly, feebly impressed along the middle almost through - 

 out; elytra evidently narrower than the prothorax and but little wider 

 than the base of the latter, parallel, two-thirds as long; abdomen one- 

 half longer than the remainder of the body, subparallel, fully as wide ai 

 the head, the first five segments very narrowly, feebly and subequally 

 impressed at base; hind tarsi but little more than half as long as the 

 tibiae, stout, the first four joints very short and subequal, the claws 

 very long, slender and evenly arcuate. Length 2.5 mm.; width 0.46 

 mm. Queen Charlotte Island (Massett), — J. H. Eeen-.borealis n. sp. 



I have before me but a sinojle specimen of undetermined sex 

 and it has unfortunately lost all but the basal joint of the 

 antennae. 



Hygronomini. 



Bamona Shp. 



. The following species belong to Bamona proper and not to 

 Gyronycha, and the first is interesting in proving its extended 

 distribution, paralleling that of Gyronycha: — 



Form slender, rather convex, polished, black or blackish throughout, the 

 legs pale piceous, the antennae black, gradually paler basally ; integu- 

 ments devoid of any trace of minute ground sculpture, very finely, not 

 densely punctured throughout; pubescence fine, short, ashy and rather 

 distinct on the elytra, elsewhere inconspicuous; head nearly as wide as 

 long, the sides very broadly rounded and converging behind the moder- 

 ate eyes to the neck, which is fully three-fifths as wide; antennae thick, 

 not quite attaining the middle of the elytra, gradually incrassate dis- 

 tally, the joints close -set, obtrapezoidal distally, opaque, densely clothed 

 with a mixture of short stiff silvery, and longer fine and dark, hairs, 

 the second longer than the third, both elongate, the snbapical moder- 

 ately transverse, the eleventh somewhat thicker, oval, rather longer than 

 the two preceding; prothorax slightly narrower than the head, some- 

 what longer than wide, widest near apical third, where the sides are 

 subprominently rounded, thence feebly converging and subsinnateto the 

 base, the surface wholly unimpressed ; elytra large, four -fifths wider and 

 two-fifths longer than the prothorax, the humeri well exposed at base; 

 abdomen much narrower than the elytra, parallel, the first three tergites 

 strongly but narrowly impressed at base; hind tarsi slender, with the 

 basal joint about as long as the next two combined, the fifth gradually 

 thickened toward tip. Length 1.7 mm.; width 0.4 mm. North Caro- 

 lina (Asheville) carolinae n. sp. 



Form very slender, rather convex, highly polished, minutely, rather closely
