BEETLES OF GENUS LUPERODES—BLAKE 73 
Other localities —Tucson, 16 miles south of Tucson, St. Xavier Mis- 
sion, Ariz., collected in July and August 1924 by E. P. Van Duzee and 
J. O. Martin. 
Remarks.—This species is distinguished by its tiny size, narrow 
shape, and very large eyes. The aedeagus is very similar to that of 
L. brunneus but is not so long or so slender at the tip. Three speci- 
mens of this species are in Fall’s collection at Cambridge, all from the 
Baboquivari Mountains, Ariz. 
LUPERODES PUNCTATISSIMUS, new species 
PuaTE 5, FiaureE 11 
About 4 mm. in length, broadly oval, feebly shining, conspicuously 
and densely punctate, pale yellow, a dark line down the occiput and 
rather indefinite darker areas on prothorax, lateral edges of prothorax, 
and elytra, the suture dark in one of the two specimens; antennae 
with the first three joints pale, the rest gradually darker at apex. 
Head alutaceous, finely and densely punctate over occiput, a dark 
median line, tubercles well defined, interocular space not quite half as 
wide as head. Antennae extending beyond the middle of the elytra, 
first three joints pale yellow, the rest with deeper colored apex, but 
not black, fourth joint about twice as long as third, the rest a little 
shorter and nearly equal. Prothorax one and three-fourths times as 
wide as long, with the sides nearly straight, basal margin curved; 
surface somewhat coarsely and confluently punctate, pale with two 
lateral darker areas and dark edges in one of the two specimens. 
Scutellum dark in one specimen. Elytra smoothly rounded, some- 
what convex, without depressions, surface densely and distinctly 
punctate, with finer punctures among the coarser, deeper ones. 
Body beneath pale, shining. Legs pale, first tarsal joint of hind 
leg considerably longer than rest together. Anterior coxal cavities 
closed(?). Length 4 mm.; width 2 mm. 
Type, male, and 1 paratype, female, U.S. N. M. No. 55123. 
Type locality —Arizona, ‘‘collection C. V. Riley.” 
Remarks.—This species is distinguished by its conspicuous puncta- 
tion, its broadly oval shape, its convex and not depressed elytra, and 
the characters of the aedeagus. 
LUPERODES VANDYKEI, new species 
PuaTE 5, FIGURE 3 
About 3.5 mm. in length, elongate oblong, pale yellow, with the 
head, undersurface, and apical joints of the antennae deeper in color- 
ing, faintly shining. 
Head with the interocular space over half its width, smoothly 
rounded over the occiput, shining, a depression above the tubercles. 
Antennae pale, the second and third joints together fully as long as
