AMERICAN COLEOPTERA. . 227 



was given me by Mr. Ulke as coming from Florida. Thi.s locality is 

 perhaps doubtful; if correct it indicates an example of very unusual 

 distribution. 



This species is quite distinct from any other in our fauna, and with 

 larger material would be more properly placed as a distinct group. 



22. n. lativolliK, n. sp. — Blackish-brown, more robust than usual, base of 

 antennsB. elytra and feet red-brown or yellowish. Head opake, finely granu- 

 lated, indistinctly sparsely punctured, front wide and flat, antennal ridges short, 

 but distinct as usual. Prothorax wider than long, much rounded on the sides, 

 hind angles scarcely apparent; finely granulate, opake, sparsely not deeply 

 punctured, with a narrow smooth dorsal stripe and a very indistinct dorsal line. 

 Elytra rather densely and strongly punctured, sutural angle more rounded than 

 usual; when pale colored the base is dusky. Dorsal segments very sparsely 

 punctulate; ventrals strongly, but finely and not densely punctured. Mandi- 

 bles with the tip long and slender. Side margin of prothorax acute, Hanks 

 concave along the margin, episterna narrow, parallel, coxal fissures open. 

 Length 4 mm; .16 inch. 



^. — Front angles of epistoma slightly elevated; two small distant tubercles 

 just behind the frontal suture. Ventral segments alike in both sexes. 



San Diego and Los Angeles, Cala. ; found abundantly by Mr. G. R, 

 Crotch. This species again breaks the homogeneous character of this 

 group, and were it n^t for the open coxal fissures would be better 

 associated at the end of the preceding group. 



2.3. B. longiponnis, Mneklin, Bull. Mosc. 1852, ii, 318.— Black, finely 

 pubescent, tarsi brownish. Head opake, finely granulate, front wide, flat. 

 Prothorax not wider than long, sides broadly rounded from the front angles 

 for more than half the lengtli, then subangulated, and feebly sinuate to the 

 hind angles, which are nearly rectangular; disc opake, feebly punctulate, 

 finely granulate, dorsal line very fine. Elytra rather longer than usual, a little 

 wider than the prothorax, finely and densely punctured. Dorsal segments 

 shining, sparsely punctulate; ventrals strongly and finely punctured. Side 

 margin of prothorax acute, episterna parallel, concave along the side, coxal 

 fissures open. A]iical part of mandibles long and slender. Length 4.5 mm; 

 .175 inch. 



%. — Eighth ventral segment with a small acute incision. 



Britit^h Columbia, one specimen; previously described from Alaska, 



24. B. liitcipoiiilis, n. sp. — Black, legs and elytra brownish-yellow, an- 

 tennre broken. Head and prothorax very finely granulated, subopake; the 

 latter not wider than long, rounded at the sides, hind angles very obtuse, 

 rounded and indistinct, punctures sparse, small and not dee{>, dorsal line deep. 

 Elytra longer than usual, rather finely and densely punctured, suture dusky 

 towards the base; apical angle more rounded than usual. Dorsal segments 

 nearly smooth, anus brown; ventral segments dark-brown, strongly and finely 

 punctured. Side margin of prothorax acute, episterna rather wide, nearly flat, 

 sutures extending only to the co.xal fissures, which are open. Mentum with a 

 small deep impression near the hind tiiargin. Lengtli .3 mm; .12 inch.
