LeConte.] 382 [Feb. 1, 
ture, and three occipital foveæ of equal size. Prothorax broader than long, 
distinctly narrowed behind; pellucid margin rounded, dilated inwards 
towards the base ; disc feebly lobed at the sides ; feebly punctulate at the 
middle, more distinctly towards the sides; with two vague transverse im- 
pressions, one before, the other behind the middle ; dorsal line interrupted, 
sometimes obsolete, discoidal lines sinuate, well marked; lateral im- 
pression large. Elytra with rows of fine, close-set punctures, not effaced 
towards the tip. Legs dark testaceous. Length 1.5 mm.; .06 inch. 
Gilroy, California, Mr. Crotch; Arizona, Dr. Horn. A 
nearly similar specimen from Canada is also in his collec- 
tion; 1t is rather stouter in form, and the prothorax is more 
narrowed behind, but I am unwilling without a larger series 
of specimens to consider it distinct. 
RHINOSCEPSIS n. g. (PSELAPHIDA.) 
Head sub-pentagonal, a little longer than wide, sides parallel behind the 
eyes, base truncate, hind angles rectangular, rounded at tip. Antenne 
inserted under a narrow frontal protuberance (which projects over the 
mouth, somewhat like the prothoracic horn of Notoxus), 1st and 2d joints 
thick, the former nearly twice as long; 3d-8th small, rounded; 9th rounded, 
a little larger ; 10th slightly wider ; 11th ovate, acute at tip, longer than the 
three preceding united. Maxillary palpi as long as the head, slender, last 
joint ovate acute, similar in form to the last joint of the antenne. Prothorax 
pentagonal, not convex, with a deep sub-interrupted dorsal channel, and a 
transverse impression behind the middle. Elytra not convex, with a deep 
sutural stria, a fine dorsal one near the sutural, a sub-apical fovea near the 
sides, and a marginal stria nearly as deep as the sutural. Dorsal surface of 
abdomen broadly margined, segments 1-3d equal in length. Tarsi with a 
single claw. 
cd. Penultimate ventral segment strongly and broadly emarginate, last 
segment longitudinally impressed ; front tibie much thicker at the middle. 
gradually attenuated at base and tip. 
©. Last ventral segment large, semi-circularly impressed in front, with 
a few long hairs intermixed. : 
21. R. bistriatus, n. sp.—Brown, sub-depressed, not shining, finely 
pubescent. Head with two occipital fovex and an elongate, but not deep 
frontal impression ; eyes very small, rounded ; prothorax scarcely wider 
than long, dorsal channel deepest at the intersection with the transverse 
impression. Elytra with sutural, and marginal strie very deep, a fine 
dorsal stria near the sutural, and sub-apical fovea near the marginal stria ; 
surface finely punctulate ; wider than the prothorax, gradually broader 
from the base almost to the apical truncature. Abdomen a little longer than 
the elytra, finely punctulate. Length 1 mm.; .041 inch.
