SMICRONYX WEEVILS—ANDERSON 229 
scales at the bases of the third intervals. Underside of the thorax 
and abdomen sparsely covered with linear scales. Side pieces of 
thorax covered with broad, rounded scales. Femora only slightly 
clavate, thinly covered with linear scales. ‘Tibiae thinly covered 
with scales similar to those of femora. Tarsi thinly covered with 
slender scales, the third segment much broader than the first two; 
fourth segment extending well beyond the third; claws small, sub- 
parallel, connate for approximately half their length. Median lobe 
of male genitalia lightly sclerotized along middorsum, sides subparal- 
lel, internal sac armed with broad, but sharp, spines and heavily 
sclerotized near bases of orificial plates; spiculum gastrale curved, but 
not hooked at its anterior end (fig. 58). 
Measurements: The following measurements were taken from 6 
males and 8 females from Woodland, Calif. (USNM), and 2 males 
from Bass Lake, Madera Co., Calif. (CAS). All measurements are

Brotocy: A single host plant record was taken from the material 
examined, “‘Ex Dodder,” Bass Lake, Calif., July 7 (CAS). Pierce 
(1939) reported taking this species (under the name Smicronyx 
elsegundinis Pierce) on Cuscuta californica at El Segundo, California, 
on June 15 and June 29. 
Discussion: S. seriatus strongly resembles S. apionides Casey in 
regard to body and scale color, general body shape and genitalia, but 
S. apionides has scattered patches of broad white scales on the elytra 
and a subcylindrical, deeply sculptured prothorax, neither of which is 
true of S. serzatus. In addition, the median lobe of the male genitalia 
is lightly sclerotized along the midline of the dorsum in S. seriatus, but 
not in S. apionides. 
A comparison of several paratypes (which were also topotypes) of 
S. elsegundinis Pierce with the lectotype of S. seriatus showed them to 
be in such close agreement with the latter that the species described 
by Pierce as S. elsegundinis is considered by the writer to be con- 
specific with S. seriatus LeConte.
