shorter, never attaining the hind angles of the pronotum ; the metasternum is 

 moderately, closely punctate at the sides, but very much mine finely and remotely 

 at the middle, while in vanus there is not much disparity. (PI. IV, fig. 25). 

 Length 1.6-1.9 mm. 



Hub. — Arizona (Chiricahua Mts. — Schwarz). 



K. vent.rali"* sp. nov.— Moderately, broadly ovate, convex, reddish brown 

 throughout. Head transverse, rugosely punctate, median sulcus distinct, a little 

 deeper and wider behind ; eyes prominent ; tempora about one-fourth the length 

 of the eyes, subparallel ; antennae not quite reaching the hind angles of the pro- 

 notum, all joints longer than wide. Prothorax transversely quadrate, sides 

 nearly straight and parallel, rounding in a little at the front angles; margin 

 obsoletely, minutely serrulate ; surface rugosely punctate, median sulcus shallow, 

 broader in front, posterior transverse impression deep. Elytra rather broadly 

 ovate, not impressed toward the base, striae feebly impressed, punctures of moder- 

 ate size at base, gradually finer posteriorly ; intervals nearly flat on the disk, the 

 seventh acutely carinate nearly throughout its length. Metasternum distinctly, 

 moderately closely punctate at sides, more sparsely toward the middle: post- 

 coxal fovese deep, the radiating rugae short aud inconspicuous. Ventral segments 

 impunctate; the first with two short, posteriorly inclined bristles or spines near 

 the middle of the hind margin ; the fifth truncate, the truncature feebly sinuate 

 and with the side angles a little prominent. (PI. IV, fig. 26). Length 1.65 mm. 



Hub. — California (Los Gatos and Lake Tahoe). 



Two examples in the Hubbard and Schwarz collection are all that 

 I have seen of this interesting and very distinct species. There is 

 little doubt that the ventral peculiarities above described are sexual. 

 Nothing similar has been observed elsewhere, and they will render 

 the species at once recognizable if males are at hand ; if not, the 

 sculpture of the under surface, the parallel sided thorax and cari- 

 nate seventh interval of the elytra will serve quite as well. 



K. cordatiiM Belon. — Broadly oval, convex, red-brown. Head densely ru- 

 gosely punctate, without median sulcus; eyes rather small but prominent, tem- 

 pora apparently about one-third the length of the eye ; antennae slightly passing 

 the middle of the prothorax, the first joint subglobular as usual, all others 

 longer than wide, except the tenth, which is about as wide as long. Prothorax 

 three-fourths broader than the head, transversely cordate, moderately strongly 

 rounded in front, scarcely sinuate before the hind angles, which are oblique; 

 side margins rather broadly explanate and a little reflexed. minutely, indistinctly 

 crenulate: surface coarsely, densely, rugosely punctate and opaque, disk convex, 

 the median sulcus obsolete, basal depression broad, deeper at the sides. Elytra 

 moderately shining, broadly ovate, convex, without subbasal impression : margin 

 explanate; stria' a little impressed, the punctures rather strong toward the base. 

 finer apically: intervals very slightly convex. Metasternum with deep post- 

 coxal foveas, and numerous longitudinal rugae, especially toward the sides. First 

 ventral impunctate and with a few very fine and indistinct rugae. (PI. IV, fig. 

 27). Length 1.7 mm. 



Hab. — Oregon ; British Columbia (North Bend — Schwarz).
