pale pubescence; anterior coxal cavities open. Legs pale, each tibia 
spurred, first hind tarsal joint not so long as the rest together. Length 
4.24.9 mm., width 1.8-2 mm. 
Type, male, and 2 paratypes (female), U.S.N.M. No. 55111. 
Type locality—Los Angeles, Calif., collected by Coguillett. 
Remarks.—The uniform color of the dark antennae, in which neither 
basal nor apical joints are paler, and the dark vitta that is usually 
present on the pronotum differentiate this species from the other 
vittate ones. Two specimens in the Los Angeles Museum are labeled 
Los Angeles County, collected by M. Albright, and “Cal.,” 
respectively. 
LUPERODES TUBERCULATUS, new species 
Puate 6, Figure 19 
About 4 mm. in length, oblong oval, faintly shining, yellow-brown, 
with narrow sutural and lateral piceous vittae on the elytra. In 
male a pair of tubercles in the middle of the abdomen. 
Head shining, pale yellow-brown, smoothly rounded over the 
occiput, a transverse line above the tubercles extending from eye to 
eye, interocular space over half the width of the head; a slight pro- 
tuberance between the antennal bases. Antennae entirely pale, 
extending to the middle of the elytra, second and third joints about 
equal, fourth not so long as second and third together. Prothorax 
about a fourth wider than long, with arcuate sides, not very convex, 
surface shining, very finely punctate, entirely pale. Scutellum pale. 
Elytra oblong, smoothly rounded with small humeral prominences, 
shining very finely punctate; pale yellow-brown, with the sutural edges 
Ppiceous almost to the apex, and a narrow lateral vitta extending over 
the humerus nearly to the apex, these two joined by a dark edge about 
the base and scutellum. Body beneath entirely pale. In male a 
pair of tubercles in the middle of the abdomen. Anterior coxal 
cavities open, hind tibiae spurred (others not visible). First hind 
tarsal joint not quite so long as the remaining ones together. Length 
4—4.5 mm.; width 1.8-2 mm. 
Type, mile. and 3 paratypes (2 male, 1 female), the type and 1 male 
paratype in collection of the Los Angeles Museum, 2 paratypes in 
National Museum collection, U.S.N.M. No. 55112. 
Type locality—Camp Baldy, at the foot of Old Baldy Mount, 
San Antonio Mountains in San Bernardino County, Calif., collected 
June 17, 1916, by L. L. Muchmore. 
Remarks.—The outstanding peculiarity of this species is the presence 
of a pair of well-developed tubercles on the abdomen of the male. 
I have not seen these on any other American beetle, although they are 
known to occur in such genera of the Galerucinae as Phyllobrotica and 
Hoplasoma in Europe and Asia.
