10 THE CANADIAN ENTOMOLOGIST. 



width of disk four-fifths ( g ), eight- or nine-tenths ( ? ), the length. 

 Prozone considerably contracted, with the disk rather more than ordinarily 

 wrinkled, as long as or slightly shorter than half the length of the some- 

 what coarsely granulated metazone, the latter slightly convex both antero- 

 posteriorly and transversely. Median carina prominent throughout, 

 strongly cristate and bilobate on the prozone, the posterior notch 

 especially deep and somewhat oblique ; cristate on the anterior part of 

 the metazone. Lateral carinae very sharp and prominent on the metazone, 

 continued forward a short distance on the posterior part of the prozone. 

 They are also present to a variable extent on the anterior part of the 

 prozone. Tegmina rather long, of moderate width, pale dull brownish, 

 sprinkled throughout with grayish fuscous annuli, which form a more or 

 less distinct group occupying the basal third or fourth, and also show a 

 tendency to collect in the middle of the tegmen, but do not form anything 

 that could be called a band. Area of the cubital forks rather narrow, 

 usually occupied by two or three rows of irregular cells, or, as in one £ 

 which I have, by a single row of cubical cells. Wings fully three-fifths as 

 wide as long ; disk pale yellow ; fuscous band crossing about the middle 

 of the wing not reaching the anal angle, the outer margin less curved than 

 the inner, so that the band is considerably wider where it meets the outer 

 margin of the wing than it is at the costal margin. Greatest width of band 

 varying from one-fourth to slightly more than one-third the length of the 

 wing. Spur extending very nearly to the base. Apical portion of the 

 wing hyaline, with a few fuscous spots near the apex in the 3 > none of 

 the veins whitish. Outer face of the hind femora plain grayish-brown, or 

 with faint indications of darker bands ; inner face black, with two light 

 bands, a median and a preapical, the upper sulcus with an additional light 

 band near the base ; lower sulcus black, with one preapical light band. 

 Hind tibine pale yellowish, slightly darkened apically.
