SCIAGRAPHIA GRANITATA Guenee. 



Fifteen .specimens, May 29, June 2, 3, 5, 10, 16, 24, 25, 29, July 10 

 (Ainsworth), 29 (Bear Lake Mountain), and three from Mr. Cockle's 

 collection. Two of these bear labels ''^p^m.ctolinemia Packard" and 

 '"''niiblculata Packard," ])ut I think these determinations erroneous. 

 The larva will be described by me in Life Histories of North Ameri- 

 can Geometridaj, LVI. It feeds on spruce and mimics the needles of 

 the second year's growth in color. 



SCIAGRAPHIA DENTICULATA Grote. 



No specimens; one in Mr. Cockle's collection agrees rather nearl}-, 

 though not exactly, with one from Montana so named for me by the 

 late Doctor Hulst. 



SCIAGRAPHIA NEPTATA Guenee. 



Twenty specimens; May 3], June 3, 16, 23, Jul}" T, IS (bred), 21, 

 31, August 3, 4, 18, September 8 (Glacier, dead in a lamp). Rather 

 variable in color, the lines more or less sinuous, the yellow shading in 

 the transverse posterior line sometimes obsolete. It is very nearly 

 allied to irrorata Packard. Both feed on the poplar. I shall describe 

 the larva of neptata in Life Histories of North American Geometridse, 

 LXIIl; irrorata was described in No. XXX." 



SCIAGRAPHIA CONTINUATA Walker. 



No specimens; one in Mr. Cockle's collection is small and worn, but 

 apparently refera])le here. 



MACARIA MINORATA Packard, var. INCOLORATA, new variety. 



Five specimens; May 29, June 11, 25, 26, antl one from Mr. Cockle's 

 collection August 5, 1902. The form differs from the eastern minorata 

 in its slightly larger size, nearly obsolete emargination of the outer 

 margin of fore wing, and obscure gray coloration, all the contrasts of 

 the black and reddish marks being lost and the head and collar being 

 gray with only a trace of the orange marking. It will not unlikely 

 be found to represent a distinct species, but I prefer to list it for the 

 present as a western race of minorata. 



Type.—C^i. No. 7879, U. S. National Museum. 



CYMATOPHORA LATIFERRUGATA Walker. 



No specimens; one in Mr. Cockle's collection so named. In Bulle- 

 tin No. 52, United States National Museum, Doctor Hulst makes this 

 species synonymous with ^y'^^'^^w/^^'^V^Hubner. although in 1895 he "felt
