separated foveae of Pycnoplectiis, and resembling Eiipledus in this feature 

 as well as in the linear subdepressed form and general facies, but the eyes 

 are far down on the sides of the head and tlie antennae much more like 

 those of Trimium^ having the last joint relatively large, as in Actium, the 

 ninth and tenth short, though not shorter than the preceding joints, and 

 less transverse and lenticular than in the Triinium series. The four 

 species in my cabinet are assignable to two groups, as follows : 



Cephalic foveae united by a broad, deep and continuous ambient sulcus, 

 the frontal margin thick and convex 2 



Cephalic foveee large, though in the same position, elongate-oval, 

 disconnected from the transverse frontal sulcus, the frontal margin 

 acute and laminate 3 



2. Body extremely slender, filiform, pale flavo-testaceous in colour, some- 

 what shining, the pubescence rather abundant and distinct but 

 decumbent ; head subparallel, but little wider than long, punctured 

 laterally ; prothorax as long as wide, narrower than the head, of the 

 usual form in Euplectus^ the surface finely, loosely punctate, more 

 strongly basally ; transverse sulcus subobsolete ; elytra parallel, but 

 little wider than the head, much longer than wide, the juxta- 

 humeral impression obsolete at basal fourth ; abdomen parallel, 

 almost as wide and fully as long as the elytra. Length, 0.85 mm.; 

 width, 0.2 mm. ( ? ). District of Columbia and Pennsylvania 

 (Westmoreland Co.) perte?iuis, Csy. 



Body slender, linear and subdepressed but broader and perceptibly 

 larger than in pertenuis, pale testaceous, rather inconspicuously 

 pubescent ; head but slightly wider than long, parallel and straight 

 at the sides, broadly sinuate at base, the eyes at more than their own 

 length from the rounded basal angles ; surface moderately convex, 

 polished, the two small deep perforate and nude foveas mutually 

 separated by a little less than either from the eye, the ambient sulcus 

 shallower that in /<?r^<?;/7/ij/ surface sparsely but coarsely, not very 

 deeply punctate laterally ; tenth antennal joint fully three times as 

 wide as long, the eleventh rather longer than the four preceding 

 combined ; prothorax about as long as wide, narrower than the head, 

 more broadly rounded at the sides anteriorly than in pertemdsi 

 polished, sparsely, subasperately punctate, the fovese large as usual, 

 the transverse sulcus barely traceable; elytra slightly shorter than the 

 head and prothorax, but little wider than the former, slightly though
