SMICRONYX WEEVILS—-ANDERSON 341 
elongate-ovate ochreous scales which are oriented toward the midline 
from sides and base. 
Elytra piceous, moderately convex, covered with a mixture of ochre- 
ous and light yellow, ovate scales, the light yellow scales forming 
irregular interrupted transverse bands which give the elytra a rather 
mottled appearance. Scales of venter of the thorax and abdomen 
broader and more rounded than those of the dorsum, varying in color 
from very pale yellow to deep yellow. Femora reddish brown, cov- 
ered with small elongate-oval yellow scales. Tibiae reddish brown, 
bearing rows of elongate-oval scales; moderately expanded near apex, 
particularly in the hind pair. Fourth tarsal segment fairly elongate, 
the claws moderately divergent. Median lobe of the male genitalia 
quite elongate, the internal sac rather granular on outer surface (fig. 
99). Arms of the spiculum ventrale of female genitalia forming a 
rather narrow V; apex of the stem only slightly expanded (fig. 145). 
Measurements: The following measurements were taken from 2 
males and 1 female from Palos Park, Ill. (CNHM), 2 females from 
Summit, Ill. (CNHM), 1 male and 2 females from Willow Springs, 
Ill. (CNHM), 2 males from Dickinson Co., Iowa (USNM), 1 male from 
Pottawatomie Co., Iowa (USNM), and 1 female from West Quincy, 
Mo. (CNHM). All measurements are in millimeters:

Broutocy: There is no biological information available on this 
species at present. 
Discussion: This species resembles S. fulvus LeConte and S. 
sordidus LeConte in general body shape and proportions, prothoracic 
punctation, and in having a rather straight rostrum, but may be dis- 
tinguished from S. fulvus by the mottled appearance of the elytra (as 
noted in the key on p. 333) and from S. sordidus by the ochreous and 
light yellow scales (as opposed to white or gray scales in S. sordidus). 
Blatchley and Leng (1916) considered S. compar to be the female of 
S. scapalis LeConte, but, as indicated in the discussion of S. scapalis, 
it is quite clear that this is not the case now that both sexes of the two 
species are known.
