SMICRONYX WEEVILS—ANDERSON 239 
white scales grouped in scattered patches, giving the elytra a mottled 
appearance. Femora rufopiceous, moderately clavate, covered 
with elongate-elliptic white scales. Tibiae stout, piceous, covered 
with elongate yellowish white scales. ‘Tarsi rufopiceous; third segment 
distinctly broader than first two; fourth segment extending moderately 
beyond third; claws almost parallel, connate for approximately half 
their length. Median lobe of male genitalia gradually broadened 
toward apex; internal sac armed with heavy spines near median 
orifice, covered with fine spines near the apical end (fig. 62). Stem 
of spiculum ventrale of female genitalia unexpanded at the anterior 
end (fig. 111). 
MeasurEMENts: The following measurements were taken from 
6 males and 1 female from Los Angeles Co., Calif., and 1 female from 
Alameda Co., Calif. All measurements are in millimeters:

Brouoey: Pierce (1939) reported collecting this species (under the 
name Smicronyx celaenus Pierce) May 18, June 13, and June 28 on 
Cuscuta californica, and rearing some specimens from the capsules of 
that plant on July 18. 
Discussion: After examining the lectotype of Smicronyx defricans 
Casey and the type specimen of S. nubidlus Dietz, the writer has con- 
cluded that both specimens are representatives of the same species on 
the basis of their morphological similarity. The name Smicronyz 
nubilus Dietz has therefore been placed in synonymy with the name 
Smicronysz defricans Casey. 
A comparison of several paratype specimens of Smicronyz celaenus 
Pierce with the lectotype of S. defricans Casey did not reveal any 
differences that would indicate that more than one species was rep- 
resented in that material. Therefore, Smicronyx celaenus Pierce is 
considered by this writer to be synonymous with Smicronyx defricans 
Casey. 
Distrrisution: S. defricans has been recorded only from coastal 
regions in California. The following specimens were examined:
