Discussion. — This subspieces ranges across the provinces of south- 

 ern Canada from Newfoundland to Alberta and in the northern United 

 States as far south as New York, Michigan, northern Illinois, central 

 Iowa, W3^oming, and northern California. This southern limit of range 

 rouglily approximates north latitude 41°. 



The reported habits of this subspecies differ in no important respects 

 from the life histories that have been worked out for European species. 

 The present form hibernates as an adult (Parshley, 1923), feeds on 

 labiate plants in the j^oung stages (Van Duzee, 1905), and, as imago, 

 has a variety of feeding tastes, adults having been reported from vari- 

 ous plants, especially Scrophulariaceae (Provancher, 1886), from wild 

 raspberries (Parshley, 1923) and from Compositae, Cyperaceae, and 

 Graminae (Hendrickson, 1930). It appears to be adaptive to a 

 variety of habitats, as indicated above, and by reports that it has also 

 been taken under boreal conditions on the summit of Mount Greylock 

 at some 3,500 feet elevation (Parshley, 1920). One report (Torre 

 Bueno, 1915) said that even this species has the ability to burrow 

 "into the sand for shelter."

Diagnosis. — The lack of pale spots on the corium appears suffi- 

 ciently diagnostic for the recognition of this subspecies. 



Description. — Male : 



Head : Wider than long, 1 . 12 (1 .03-1 .20) : 0.88 (0.80-0.93) ; anteocular 

 length averaging just about half (49 percent) of anteocular width, 

 0.36(0.33-0.40) :0. 73(0. 68-0. 76); juga narrowly reflexed, margins 

 acute, punctured nearly or quite to edge. Antennal segments: 

 I, 0.22(0.20-0.23); II, 0.38(0.36-0.40); III, 0.47(0.43-0.53); IV, 

 0.65(0.63-0.71); V, 0.84(0.80-0.93). Labial segments: I, 0.33(0.30- 

 0.36); II, 0.57(0.54-0.60); III, 0.57(0.53-0.60); IV, 0.40(0.40-0.40).
