SMICRONYX WEEVILS—ANDERSON 315 
Discussion: The species of this group resemble the species of the 
S. corniculatus group (figs. 6, 7) in shape of prothorax, elytra, and 
rostra, but the male genitalia of the species of the S. griseus group 
are elongate, as in the S. ovipennis and S. abnormis groups (compare 
figs. 85, 88, 89). The silvery gray scales on the prothorax and 
elytra are an additional distinctive feature of the two species in the 
S. griseus group. 
Map 15 gives the distribution of this group.
