36 THE CANADIAN ENTOMOLOGIST 



with anything else listed by me in this series of papers. One of 

 these I have compared with the types of boretha and labelled it 

 "Like female type but greyer." On this comparison I base the 

 present record, but it may be as well to remark that my notes state 

 that "The male type is almost like some ochrogasier." Whereas 

 my two females bear not the slightest resemblance to any ochro- 

 gaster that I ever saw, my note seems to suggest that either the 

 range of variation in boretha is very wide, or that the female type 

 is not really the same species as the male. 



The same Pine Creek female I also compared with the unique 

 female type — lacking abdomen — of Porosagrotis thdnalologia Dyar, 

 from Kaslo, which I found in the Washington collection. (Proc. 

 U. S. Nat. Mus., XXVII, p. 833, 1914— "Kootenai List"). I noted 

 that it was probably the same species, but my specimen did not 

 match it sufficiently closely to justify making a positive reference. 



625. Rhizagrotis querula sp. nov. — Head, collar, thorax, 

 and primaries uniform pale fuscous brown, faintly olivaceous, 

 sparsely irrorate with darker scales, but without any streakiness or 

 contrast in shades. Lagena, to which the new species is closely 

 allied, has the inferior portion of the collar paler than any other 

 part of the insect,' and the upper portion contrastingly dark brown, 

 these two shades being divided by a black line, absent in querula. 

 Lagena, in all its observed variations is longitudinally streaky, the 

 most conspicuous streaks consisting of long, inwardly dentate or 

 sagittate dark brown marks on the termen, which contrast with the 

 intervening pale streaks bordering the dark veins, especially on 1, 

 3, 4, and 7. In querula, though there is a faint indication of a 

 series of dark subterminal shades in the interspaces, most evident 

 in the male type, but entirely lacking in the female, the actual 

 terminal space is in all six specimens very slightly paler than that 

 immediately preceding it. In querula the conjoined discoidal spots, 

 though outlined by a pale shade and partially defined by black 

 scales, have not the whitish annuli of lagena, and unlike those of 

 that species, are not contrasted by a darkening of the cell before 

 and below them. A fine black basal streak is present in all but 

 one, and all show indications of dark t. p. lines, produced to points 

 on the veins, and in two of the males they are well marked, con- 

 tinuous, some specimens showing a faint t. a. line as well. But
