distinct, I think. The larva was not obtained. Mr. Taylor has pointed 

 out to me, and the experience of other resident collectors in British 

 Columbia corroborates him, that in 1902 and previously dcfcnmiia 

 was the common species, Avhilc conixdlarla was rare, while in YMYi the 

 conditions were reversed. This is in agreement with my captures and 

 appears to me to further indicate the distinctness of the two species. 



PETROPHORA FERRUGATA Clerck. 



Two specimens, June 24 (Mr. Cockle), August 22 (Revelstoke), and 

 two from ]Mr. Cockle's collection, July 31, 1901, August 23, 1902, the 

 latter a female apparently agreeing with Hulst's horealls. 



COSYMBIA LUMENARIA Hiibner. 



Seven specimens, June 1(), 18, 25, July 2. They are mostly large, 

 and of a dark, even stone gray, the lines ncarl}^ lost. My Eastern 

 specimens, and others from Corvallis, Oregon, and Wellington, while 

 variable, are all much lighter, some nearly white, with distinct mark- 

 ings. One of the Kaslo specimens, however, is nearh^ normal, thus 

 dispelling the idea of a local race. Eggs were obtained from a captive 

 female, but I was unable to find the food plant. 



Egg. — Elliptical, strongh^ flattened, compressed, one end smaller 

 and depressed, both rounded; reticulations uniform, rounded and 

 broad, elongate hexagonal, low rounded bars, the areas between nearly 

 flat, granular shagreened. Pale yellow; &ize, 0.9 by 0.5 b}'- 0.3 mm. 



Stage I. — Head rounded, full, pale brown, slight!}' darker mottled 

 over the sides, a dark band on the median suture, edged with lighter. 

 Body moderate, not elongate, feet normal; pale brown, a broad dark- 

 brown dorsal band, a similar less distinct ventral one, diluted on the 

 posterior rims of the segments. Feet' pale; segments irregularly 

 annulate; tubercles minute, brown; seta^ moderate, fine, minutely 

 enlarged at tip. 



XYSTROTA HEPATICARIA Guenee. 



No specimens; one from Mr. Cockle's collection, June 1 (Ains- 

 worth). 



LEPTOMERIS QUINQUELINEARIA Packard. 



Nineteen specimens, June 15, 18, 23, 24, )>b, July 1, 2, 4, 0, IT, 21 

 (Bear Lake, IVIr. Cockle) and one from ^Ir. Cockle's collection, June 

 17. The larvie will l)e described by me in Life Histories of North 

 American Geometridie, LXII. 



LEPTOMERIS SIDERARIA Guenee. 



Four specimens, June 24, 29 and one from Mr. Cockle's collection. 

 This species was placed by Doctor Ilulst in Kols^ but, as the females 

 have four spurs on the hind tibiie, 1 change the generic reference.
