behind the middle; sides parallel from the base to the apical curve, the 

 sides posteriorly not serrate, the tips much narrowed, feebly bidentate; 

 feet and under surface bright cupreous, rugosely punctate; tibiae long, 

 slender; venter almost rounded at tip; pectus feebly canaUculate. 

 Length 10. o mm.; width 3.5 mm. Pennsylvania. [ =Dicerca gracilipes 

 Mels.] gracilipes Mels. 



Form slender, moderately convex, fusoid, above slightly shining, blackish 

 with feeble cupreous reflections, except the elytral foveolae which are 

 greenish, beneath more cupreous and less glabrous, each puncture hav- 

 ing a small decumbent hair; head nearly as wide as the thoracic apex, 

 obscure in color, the front flat, rather finely, densely, almost uniformly 

 punctato-rugulose and evidently pubescent, without trace of transverse 

 callus but with the median line shghtly elevated and smooth near the 

 centre; antennae piceous, with slight cupreous lustre except apically, 

 very slender, extending somewhat beyond the thoracic base; eyes well 

 developed, rather convex and prominent; epistoma cupreous, the sinus 

 small, deep, parabolic; prothorax widest at base, nearly one-half wider 

 than long, feebly trapezoidal, the sides very feebly arcuate, becoming 

 straight basally, the angles not at all everted; apex broadly sinuate, the 

 base arcuate, becoming feebly sinuate near the sides; surface strongly, 

 rather sparsely and subevenly punctate medially, with a deep entire 

 median sulcus which is broadly impressed posteriorly, becoming more 

 acute anteriorly, and another, near each side, very feeble anteriorly 

 but becoming deep at base, concave and densely punctate and bounded 

 externally by a tumid and less punctured ridge, which is obsolescent 

 anteriorly; scutellum small, flat, opaque, blackish; elytra but Httle 

 wider than the prothorax and about four times as long, separated 

 along the inner sides in the type from basal fifth to the apex; sides par- 

 allel and nearly straight for three-fifths, then very gradually rounded 

 and convergent, even and without trace of serrulation to the narrowly 

 transverse sinuato-truncate apices, which are feebly bispiculose; sur- 

 face with rather coarse, uneven interrupted striae, except laterally, 

 with the narrow intervals alternately a little more prominent, strongly 

 so apically, very unevenly but closely, rather coarsely punctate and rugu- 

 lose, more sparsely and coarsely on the general surface but more 

 densely and finely in the shallow and very uneven vague depressions, 

 of which there is one very large and obliquely transverse before the 

 middle and some smaller from the middle to the apex, the small punc- 

 tate patches well separated along the smoother sutural intervals much 

 as in Dicerca; prosternum perfectly flat, transversely truncate ante- 

 riorly, rather coarsely, closely and evenly punctured throughout; entire 

 metastcrnum equally densely and uniformly but less coarsely punctate, 

 the abdomen much more sparsely, especially toward the middle, and 

 more polished and ratlicr narrowly sinuato-truncate ajncally in the type; 

 legs long, very slender, the basal joint of the hind tarsi as long as the 

 last three combined. Length 10.5 mm.; width 3.2 mm. Texas.
