888 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxvii. 



A number of ne.sts of the larvi\3 were found at different times eariy 

 in spring on several deciduous trees, A fresh egg mass was noted on 

 a birch twig in August. 



EPICNAPTERA AMERICANA Harris. 



One example, June 2, almost t3^pical cvmerlccma like ^Vtlantic coast 

 specimens. There is a little obsolescence of the white markings, 

 indicating the first step toward the va,Y\Qty ferruglnea Packard. The 

 larvae were beaten from Ceanothus and were of the normal appearance. 



Family PLATYPTERYGID^. 



DREPANA ARCUATA Walker, var. SICULIFER Packard. 



No specimens; Mr. Cockle has a few in his collection. As I recol- 

 lect, they are similar to those occurring on the coast which I have 

 from Seattle, Washington (Kincaid), Wellington (Taylor), and Port- 

 land, Oregon (Dyar). In Bulletin No. 52 of the U. S. National 

 Museum, I listed slculifer as a distinct species, but I would no longer 

 maintain that. The race is larger only. Both spring and summer 

 forms occur, differing as do the eastern forms arcuata Walker and 

 genicula Grote. A few larvas occurred on alder with the appearance 

 and habits of the eastern race. 



FALCARIA BILINEATA Packard. 



No specimens; but Mr. Cockle has six in his collection. They 

 probably do not differ from a specimen that I have from AV'ellington 

 (Taylor). It is the same as the Atlantic coast form, l)eing scarcely 

 larger even. Mr. Cockle has both the forms hilineata Packard and 

 lev'is Hudson. His dates are: Spring form hilineata, June 17, July 

 Y; summer form levls^ July 31. 



A few larva^ occurred on birch with the appearance and habits of 

 the Atlantic coast form. 



Family GEOMETRID.^. 



NYCTOBIA NIGROANGULATA Strecker. 



One specimen, June 2, in bad condition, and one from Mr. Cockle's 

 collection, April 3. I have the species also from Seattle, Wasliington 

 (T. Kincaid), Wellington (T. Bryant) and Rossland (W. R. Johnson). 

 The Rossland specimen was seriously misidentitied for me by tlie late 

 Doctor Hulst, who called it Ilydrlomene cal'tforniata Packai'd var., so 

 that I lost sight of the form for several years. It is, I think, only a 

 western race of Jhnltata Walker or furc! fascia Walker, being larger 

 and darker; ])ut I do not wish to enter into the question of the specific 

 distinctness of these eastern species with my present material and 

 without knowing any larvie. Therefore I provisionally let nlgroangu- 

 Jafa stand.
