CLOVER-LEAF WEEVTL. 
deep, punctured; ante-rinse reddish-black, scape reaching to middle of eyes, not as 
long as funicle, not greatly enlarged at tip; first joint of funicle distinctly longer 
than second, enlarged at the apex so that it is about one-half as thick as long, second 
joint equal to three and four united, joints three to seven regularly shorter and 
broader, seven as wide as long, club elongate-oval, pointed at the tip, antennae with 
many fine hairs, those on club very fine and dense. Mandibles po.ished, dull red, 
not emarginate at tip, maxillae and all the palpi pale brownish-red. 
Prothorax broader than long, broader in female than in male, in the female broadly 
widened in front of the middle, in the male converging more behind than in female; 
sides broadly impressed, only slightly swollen; dorsum densely rather coarsely punc- 
tured, densely clothed with scales and with many slender pointed hairs; usually with 
a narrow pale median dorsal line bordered with wide dark, almost black in some, 
bands of scales which reach to the sides; sides and beneath with dark yellow scales, 
generally with a dark spot on sides behind and an indistinct dark line running from 
this spot toward the front. 
Scutellum extremely small, narrowly triangular, clothed with pale scales. 
Elytra very broad, at tip broadly rounded, sides especially in the male nearly 
parallel, humeri prominent and 
clothed with darker scales. _..^_«.^s^^M 
Suture and alternate inter- 
spaces more strongly elevated 
than others, deeply striately 
punctured, striae without setae; 
each interspace with a single 
row of black setae pointing 
backward and partially decum- 
bent, more erect behind ; tip of 
elytra and often the sides with 
some short white hairs. The 
coloration of the scales varies 
from solid gray to black, 
through various shades of 
brown yellows. Some speci- 
mens are tessellated with brownish-yellow and black, the tessellation usually on the 
more elevated interspaces. 
In the male the outer interspaces have paler scales even in the darkest specimens, 
in the female this pale coloration is sometimes, but rarely, entirely absent. 
Venter with lighter colored scales and many light hairs ; front coxae slightly separated, 
mesosternal process between middle coxae broad perpendicular, triangular at tip; 
intercoxal process of first abdominal segment very broad, coxae separated by more 
than their width. First segment in male impressed, emarginate posteriorly. Stem 
of male genitalia nearly or quite as broad as long. 
Legs short, stout, especially the femora; black, tarsi often ferruginous, claws long 
curved, red and darker at tips; front tibiae and hind femora distinctly curved, front 
tibiae more so in male; legs usually clothed with lighter scales and hairs than the 
h>ody, femora scaled, tibiae and tarsi sparsely haired; middle tibiae with a distinct 
apical hook. 
Egg [fig. 3]: Elongate oval, 1.1 mm. to 1.2 mm. long, 0.5 to 0.6 mm. broad, very 
regularly hexagonal ly sculptured * * *. [Watery yellow when laid, with a smooth 
shining shell, the yellow color deepening with age to pale olive green and finally 
turning to a dull black.] 
Larvae [ 2 ] (Descriptions from Riley, Folsom, and observations by the author). First 
stage: 1.5 to 2 mm. long, narrow, thickest at middle, tapering toward both ends; 
Fig. 2.— Adult clover-leaf weevil, lateral view. Much enlarged. 
2 The head widths for the different larval instars are quite constant and the averages will be found in 
Table I.
