BEETLES OF GENUS LUPERODES—BLAKE 69 
Antennae extending fully halfway down elytra, second and third 
joints together scarcely as long as fourth, remainder a little shorter 
than fourth and approximately equal, three basal joints pale, the rest 
usually dark brown except at base. Prothorax about a third wider 
than long, with slightly arcuate sides, smooth, shining, very finely 
punctate. Scutellum pale. Elytra broadly oblong oval, not depressed, 
humeri marked with a short intrahumeral depression, very finely and 
obsoletely punctate, entirely pale. Body beneath finely pubescent, 
pale, sometimes breast and femora a little darker. All tibiae with 
spines, first tarsal joint of hind legs considerably longer than the rest 
together. Anterior coxal cavities closed. Length 3.24.3 mm.; width 
1.8-2.2 mm. 
Type, male, and 14 paratypes (6 male, 8 female), U.S.N.M. No. 
55117. 
Type locality —F¥ort Sam Houston, Tex.; collected by H. H. Bishopp 
on rose, April 24, 1940. 
Other localities —Victoria, collected by R. A. Cushman on Opuntia 
and cotton, by C. M. Walker on cotton, and by W. E. Hinds on 
anemone; San Antonio (EK. V. Walter), Columbus (EK. A. Schwarz), 
Lavaca (Schwarz), Cuero (Cushman), North Braunfels (W. D. 
Pierce), Dallas (W. D. Pierce on Callirrhoe involucrata) ; all in Texas. 
Remarks.—One of the specimens of Fall’s Z. marginalis from Alpine, 
Tex. (collected July 20, 1922, 4,400-6,000 feet, by Wickham), is a male 
of this species. It is very likely the specimen mentioned in his 
description of Z. marginalis as immature and paler. But the other 
specimens of this species in his collection were identified as L. vari- 
cornis LeConte. 
It is a longer, more convex, and paler insect than varicornis. There 
is no trace of dark coloring on the pronotum or elytra, although the 
lateral edges of the pronotum are occasionally darker. The shape of 
the aedeagus, with its long, irregularly curved tip, is strikingly different 
from that of any of the related species.

PLATE 5, FicurRE 9 
About 3 mm. in length, oblong, slender, shining yellow-brown, with 
the occiput and all but the first three joints of the antennae and the 
body beneath reddish brown; head, pronotum, and elytra finely 
punctate. 
Head with interocular space over half its width, occiput smoothly 
rounded and polished, with very fine, scattered punctures; tubercles 
well defined, with a marked depression above them. Antennae 
extending below the middle of the elytra, fourth joint twice as long as 
third and slightly longer than following, which are about equal, first
