SMICRONYX WEEVILS—ANDERSON 225 
Discussion: S. atratus resembles S. sculpticollis Casey, S. tychoides 
LeConte, and S. congestus Casey in having rather convex elytra, on 
which the scales are condensed into transverse bands, and in having 
a strongly rounded prothorax. However, in S. atratus the scales of 
the elytra are mostly white and the punctures of the prothorax are 
almost round, neither of which is true of the three other species 
mentioned. 
Brotocy: Two host-plant records, which follow, were taken from 
the material examined. ‘‘Cuscuta stem” Dallas, Tex., June 29 (US- 
NM); “Cuscuta stem” Sabinal, Tex., June 2 (USNM). 
DisTRiBuTION: Present records indicate that the range of this 
species extends from the Gulf coastal plain in Texas to the southern 
Rocky Mountain region. The specimens examined are as follows: 
COLORADO: DOUGLAS Co.: Sedalia, Sept. 4 (USNM).

ville, June 5 (USNM). cHaAmBeERs co.: Anahuac, Oct. (USNM). DALLAS Co.: 
Dallas, June 29 (USNM). Limestone co.: Mexia, June 12 (USNM). wuva.pE 
co.: Sabinal, June 2 (USNM). 
Total specimens examined: 26.

Smicronyx interruptus Blatchley, in Blatchley and Leng, Rhynchophora or weevils 
of North Eastern America, pp. 220-221, 1916. Lectotype, here designated: 
Male, Posey Co., Indiana, April 19, 1904, collected by W. S. Blatchley, 
Purdue University (in W. S. Blatchley collection). 
Description: Rostra of both sexes black, stout, thick, and slightly 
gibbous at base, punctate, thinly squamose, and slightly rugose behind 
antennal insertions; finely punctate before antennal insertions; shining 
and slightly tapered before antennal insertions in female. Head 
black, finely alutaceous, sparsely squamose in front. Antennae black 
to piceous. Prothorax black, moderately rounded at sides, strongly 
narrowed and slightly constricted near apex; surface raised into 
numerous low granules, giving it a knobby appearance; thinly covered 
with broadly ovate scales, which range from medium brown to light 
yellowish white; prosternum moderately emarginate and concave. 
Elytra black, intervals covered with a mixture of brown and 
yellowish white elongate-ovate scales, white scales loosely arranged in 
narrow, irregular transverse bands. Underside of thorax and abdomen 
covered with small, broadly ovate yellowish white scales. Femora 
moderately clavate, ferruginous, black near their bases; covered with 
elliptic-ovate light yellowish brown scales. Tibiae ferruginous, cov- 
ered with elongate scales similar in color to those of femora. Tarsi 
black, covered with grayish white scales; first three segments rather 
short and broad, fourth segment not greatly exceeding the third; 
claws subparallel, connate for approximately half their length.
