172 J. L. LECONTE, M. D. 



Pennsylvania, Bedford Co., July, on oak. Quite different from 

 Eu. tennintdia and morio by the stronger and more distant transverse 

 lines of the elytra. The form is also less elongate and the elytra are 

 not red at the tips. 



EucinctiiN pnnctnlatns. — Elongate oval, rather more pointed behind, 

 convex, dark brown, pubescent. Elytra very densely and finely punctured, 

 \rithout transverse strite; sutural stria deep behind, obsolete near the base; 

 other strise wanting. Beneath finely punctulate and pubescent. Length 3 

 mm.; .12 inch. 



One specimen, Detroit, Michigan; Messrs. Hubbard and Schwartz.' 

 Very distinct by the finely and deusely punctulate elytra, without 

 dorsal strite. 



Dictyoptora rnbripennis. — Black, shining; beak as long as the head, 

 which is finely channeled, and also transversely impressed. Prothorax as 

 wide as long, sides and tip separately rounded, so that the front outline is 

 sinuous each side; disc deeply channeled, uneven each side, with an elevated 

 oblique ridge running to the side margin near the hind angles, which are acute. 

 Elytra briglit red, pubescent, rugosely punctured, with the suture, side margin 

 and four narrow discoidal lines on each, slightly elevated. Antennse com- 

 pressed serrate, with the second joint short; third a little longer than the 

 fourth. Length 12.5 mm.; .50 inch. 



One 9 specimen, Colorado, Mr. B. H. Smith. The tibiae are flat- 

 tened, somewhat dilated, and broadly concave. The dorsal channel 

 of the prothorax extends to the tip, is wider at the middle, so as to be 

 narrowly rhomboidal in form, and is again dilated at base, which is 

 nearly straight. The antennjie are half as long as the body, not 

 strongly serrate. The muzzle or beak is longer and narrower than in 

 D. per/acetus, though less so than in L^cus, and the elytral sculpture 

 is somewhat different from both. 



Dictyoptcra dimidiata. — Elongate black, very finely pubescent. Head 

 feebly channeled, short, muzzle broad and rounded. Prothorax bright rufous 

 trapezoidal, wider than long, channeled, side margins straight thickened, disc 

 foveate near the front angles, deeply and broadly excavated each side near 

 the base. Scutellum black. Elytra rufous for nearly half their length, then 

 bluish-black ; finely rugose, obsoletely striate. Antennse with the second joint 

 two-thirds as long as the third, which is shorter than the fourth. Length 

 7.5 mm.; .30 inch. 



One 9 specimen, Mariposa, California; Mr. Thevcnet. Similar in 

 form and sculpture to D. pcr/aceta, and differing chiefly in color. 



Dictyoptcra riifu'ollis. — Black, prothorax bright red, elytra blue- 

 black, finely rugose, substriate. Head concave between the eyes, muzzle 

 broad and rounded. Prothorax much wider than long, trapezoidal, channeled, 

 margins thickened, disc deejily foveate near the fr<*nt angles, very much 

 excavated each side behind, and deeply impressed transversely behind the
