three pale yellow, remainder reddish brown. Prothorax about a fourth 
wider than long with sides nearly straight, shiny, finely and rather 
closely punctate. Elytra not much wider than prothorax, without 
depressions, humeri not prominent, shining, finely punctate. Body 
beneath reddish brown with legs a little paler. Anterior coxal cavities 
open. First hind tarsal joint as Jong as the rest together. Length 
3-3.2 mm.; width 1.2—1.3 mm. 
Type, male, and one paratype, U.S.N.M. No. 55118. 
Type locality —lLas Vegas, N. Mex., collected September 8 by 
K. A. Schwarz and H. 8. Barber. 
Remarks.—This is one of the tiniest of the yellow-brown species and 
is distinguished from varicornis by its narrowly oblong shape. It 
has a peculiar spoon-shaped aedeagus. 
LUPERODES POPENOEI, new species 
Prats 5, Figure 7 
About 3.5 mm. in length, elongate oblong oval, finely and rather 
closely punctate, pale yellow, with reddish-brown occiput and entirely 
reddish-brown antennae; legs and body beneath often deeper brown. 
Head frequently with deep reddish occiput, pale below except for 
the darker mandibles; finely punctate and alutaceous, tubercles 
separated from occiput by a deep groove, front little produced, inter- 
ocular space fully half the width of the head. Antennae extending 
down to the middle of the elytra, fourth joint about equal to second 
and third together, rest a little shorter and nearly equal in length; 
entirely deep reddish brown. Prothorax about one and one-fourth 
times as broad as long, with sides only slightly arcuate, surface 
shining, densely and finely punctate; pale yellow, sometimes with a 
trace of spots. Elytra elongate, smooth, not so convex as in brunneus, 
humeri not prominent; surface shining, finely and densely punctate. 
Body beneath finely pubescent, breast frequently darker, tibiae of all 
legs with spines, hind tarsal joint about equal to the rest together. 
Anterior coxal cavities open. Length 3.5-4'mm.; width 1.8-2 mm. 
Type, male, U.S.N.M. No. 55119. 
Type locality —Kansas. 
Other localities.—Texas (Belfrage collection), Kansas (collected by 
F. H. Snow, E. A. Popenoe, and in the collection of C. V. Riley). 
Remarks.—In this species there is no suggestion of darker markings 
on the pronotum or elytra, and all the joints of the antennae are of a 
uniform color, deep reddish or piceous without any paler basal joints. 
It is more oblong and less convex than is varicornis. In the Popenoe 
collection from western Kansas is one beetle labeled “‘ Luperus n. sp. 
Lec.,’’ which very probably was examined by LeConte himself and so 
determined.
