68 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 92 
were collected on cotton. Thus the food habits appear to be pretty 
much the same in both pale and dark forms. 
Specimens of typical brunneus are in the National Museum collec- 
tion from North Carolina, South Carolina, Georgia, Alabama, Missis- 
sippi, Louisiana, Texas, Oklahoma, and Kansas. There are two speci- 
mens labeled New York, and a series labeled Rockport, Mass., but 
in both cases I doubt the authenticity of the locality label. 
LUPERODES RUGIPENNIS, new species 
Puate 5, Figure 10 
About 4 mm. in length, elongate oblong, pale yellow-brown, with 
reddish-brown occiput and a dark sutural, basal, and in part lateral 
edge on elytra, not shining, the surface of the pronotum and elytra 
uneven, the elytra showing traces of costation. 
Head deeper in color over the occiput and alutaceous; interocular 
space about half the width of the head. Antennae extending beyond 
the middle of the elytra, with pale basal joints, second and third 
joints together not quite so long as fourth. Prothorax a third wider 
than long, with sides nearly straight; surface uneven with a depression 
on each side and down the middle, finely and obsoletely punctate, 
entirely pale yellow. Elytra with more conspicuous punctation than 
prothorax and with traces of irregular, poorly defined costae, the 
surface appearing rugose; humeri not at all prominent; entirely pale 
except for the sutural, basal, and lateral edges, the last usually bemg 
dark only in basal half. Body beneath entirely pale. All tibiae 
spurred, first hind tarsal joint a little longer than the others together. 
Anterior coxal cavities open. Length 3.5-4.5 mm.; width 1.5-1.9 mm. 
Type, male, and 16 paratypes (5 male, 11 female), U.S.N.M. 
No. 55116. 
Type locality—tLas Parras, Baja California, collected by W. M. 
Mann, October 1923. 
Other localities —Purrisima, Palmarita, San José del Cabo, Baja 
California. 
Remarks —The uneven, distinctly punctate surface of this species 
and its semicostate elytra make it easily distinguishable. 
LUPERODES PALLIDULUS, new species

About 3-4 mm. in length, oblong oval, very finely punctate, shining, 
pale yellow, occiput, sometimes lateral edge of prothorax, breast, and 
femora deeper in color, the antennae usually deep brown except the 
basal joints and the base of each joint. 
Head with smoothly rounded occiput, very finely punctate, tubercles 
well defined, with transverse groove above running from eye to eye;
