PANTOMORUS OF AMERICA NORTH OF MEXICO 39 
and sometimes the hind tibiae of female with a few denticles. Median lobe, in 
dorsal view, tapering from base to apex (fig. 4, A). 
Type locality.—Texas. 
Distribution—Texas (Mineral Wells, March 20, and College Sta- 
tion); Oklahoma (Ardmore); Kansas (Meade County, May 16). 
Lectotype—Female, marked ‘Lectotype 2836,” in the Horn collection at 
Philadelphia. 
Thirty-one females and 26 males are at hand, most of them from Mineral 
Wells, Tex., and labeled “injuring spinach.” 
As in candidus and planitiatus, the male has the elytra relatively narrower, 
the prothorax more inflated laterally. and the pronotum more convex longi- 
tudinally, than in the female. In general, the eye is at least as strongly convex 
in the female as in the male. The median pronotal groove is not perceptible 
in most specimens, but occasionally traces of it are present. In some specimens 
a good many of the elytral setae are forked apically, in others very few. The 
color markings are exceedingly variable but, judging by available material, the 
color in obscurus is considerably darker on the average than in candidus and 
planitiatus. A large, grayish female from Oklahoma has the setae shorter, the 
elytral intervals nearly flat, the elytral scales not overlapping, and the eyes 
less convex than usual, the characters tending toward planitiatus. 
Distinctive features of obscurws are the small size, usually dark color with 
rather conspicuous lateral whitish vitta on pronotum, the long and abundant 
elytral setae, the spinelike teeth on the fore tibia, and the relatively few 
spinules in the distal comb. 
In the Horn collection at Philadelphia is a gray male about 5.5 mm. long, 
labeled “S. W. Tex.” and placed with the Horn lectotype of obscurus. This. 
specimen evidently belongs either to an undescribed species or to some described 
exotic species. It is more like members of the candidus group in its habitus 
and in the overlapping of the elytral scales, but the shape and arrangement of 
the elytral setae are more as in the elegans group.
