BEETLES OF GENUS LUPERODE'IS—BLAKE 65 
extending beyond the middle of the elytra, third joint about half 
as long as fourth, three basal joints pale. Prothorax widest an- 
teriorly where a little wider than long, then narrowing to base; 
disk not very convex, somewhat shining, finely alutaceous, entirely 
black. Scutellum dark. Elytra elongate oblong, not very convex, 
with small prominent humeri and a long intrahumeral depression, 
entirely black, somewhat shiny, alutaceous, and finely punctate. 
Body beneath entirely dark except for paler coxal joints, the pale 
pubescence thicker on the breast. Legs dark, apices of joints some- 
what paler, all tibiae spurred, first tarsal jomt of hind leg as long as 
the rest together. Front coxal cavities open. Length 6.2 mm.; 
width 2.2 mm. 
Type, male, 1 paratype, female, U.S.N.M. No. 55115. 
Type locality —E1 Toro, Orange County, Calif., collected May 17, 
1938, by C. Dammers. 
Remarks.—Luperodes semeflavus Fall is the only other species 
having dark or metallic elytra and a pale head, but the prothorax, 
legs, and body beneath of semiflavus are also pale. L. flavoniger 
appears to be closely related to L. californicus, having a similarly 
shaped prothorax.

The type of Lwperus varicornis in the LeConte collection at Cam- 
bridge, a female labeled ‘Ariz.,” is 3 mm. long and 1.8 mm. wide. 
The head is pale yellow, with a reddish-brown streak down the median 
line of the occiput; the mandibles are red-brown; there is a transverse 
line across the vertex and above the tubercles, and the tubercles are 
distinctly marked but not prominent; the occiput is finely punctate. 
The interocular space is about half the width of the head. The 
antennae are longer than half the body, pale at base, the first three 
joints entirely so, the fourth and remainder with darkened apical 
half, the second and third are nearly equal to the fourth, the rest 
about equal to the fourth. The prothorax is not twice so wide as 
long, slightly rounded at the sides, shining, very finely punctate, 
and pale yellow, with red-brown lateral markings along the margin 
and sides. The scutellum is reddish. The elytra are oval, a little 
wider behind the middle, shining, faintly and finely punctate, the 
punctation a little more distinct and less dense than on pronotum, 
the margin and suture reddish brown, widening at the suture to an
