SMICRONYX WEEVILS—ANDERSON 2 
light brownish yellow scales. Tibiae covered with scales similar to 
those of femora. Tarsal segments all rather short and broad; claws 
small, almost parallel, connate for about half their length. Median 
lobe of male genitalia wider at base than at apex; internal sac dis- 
tinctly spiculate and having a pair of dark, rounded sclerites attached 
to distal portion (fig. 54). 
Measurements: The following measurements were taken from 3 
males and 2 females from Jeannette, Pa. (CM), 4 females from Easton, 
Pa. (CAS), 2 females from Phillipsburg, N.J. (CAS), 2 males from 
Illinois Beach State Park, Ill. (CNHM), 3 males and 1 female from 
Brownsville, Tex. (USNM). All measurements are in millimeters:

Brioutocy: Weiss and West (1922) published an account of their ob- 
servations on the biology of S. sculpticollis in New Jersey. Numerous 
galls were noted on Cuscuta cephalanthi Engelman at Monmouth 
Junction, New Jersey, during the ‘‘first part of August.” The galls 
were subglobular (sometimes distorted or irregular), single-chambered 
enlargements of flower-cluster peduncles, 4-6 mm. in diameter, and 
mostly yellow or orange (a few greenish) in color. Most of the galls 
contained weevil larvae, pupae and adults during early August. The 
adults were identified as Smicronyz sculpticollis Casey by C. W. Leng. 
During the last part of August the galls contained many adults, which 
were beginning to emerge through circular holes in the galls. By mid- 
September, most of the adults had left the galls. Detailed descrip- 
tions of the larva and pupa were given and are quoted below: 
Larva: Length about 2.5 mm. form subcylindrical, slightly curved, tapering 
slightly at both ends; sparsely hairy, hairs short; color light yellow, head light 
brown. Head small, subcircular, slightly depressed; collum absent; epicranial 
halves separated dorsally by a very faint median suture; front triangular; gula 
indistinct, membranous; ventral mouth parts fleshy; clypeus and labrum distinct, 
former transverse; antennae minute almost obsolete; ocelli absent. Mandibles of 
biting type, broad across base, bifid at tips with a comparatively minute tooth 
below the two terminal ones. Maxilla fused with labium to near apex; lacinia 
simple, fringed with chitinous hairs on inner surface; galea absent; maxillary 
palpi two-jointed, labium fleshy with mentum and submentum fused, indistinct;
