DEILINIA RECTIFASCIA Hulst. 



Forty-eight .speciiUL'ii.s, May (Mi-. Cockle), Mav .'50, Junci 'A, 4, 5, 6, 

 9, 10, 13, 10, 20, 21, 22, 28, July 4, fS, 15 17, 25, 26, and one from Mr. 

 Cockle's collection labeled Di'llliua fivnihutrhi (jucnee. The color 

 varies from nearly white to pale ocherous, with reddish shades at the 

 outm- halves of both wings. I have described the life history in Life 

 Histories of North American (xcometrida', LII," where I have made 

 some remarks on the generic })()sition of the sp(>cies. 



DEILINIA LITARIA Hulst. 



Thirty-three specimens, A})ril 15 (Mr. Cockle), May 30, June 1, 0, 

 25, and one specimen from Mr. Cockle's collection, June 3, liJOl, 

 labelled DeU Inia falc(itari(iYiickxiv<\. Very variable, especially in the 

 females, which are markedly smaller than the males. One female 

 specimen, nearly without markings, seems to be almost the exact 

 counterpart of Packard's yf^/vv^/mrAW/'/a, described from a single female 

 from California. I think the name lltar/a will ultimately fall l)efore 

 an older one, \)QYh'A]}^ fet'i'ug ! imsai'la Packard, or f(i>inln((i'la ( Juenee, or 

 falcatarla Packard; but as there are man}' species of Dell hi ia attached 

 to CecDwtJiKu in the West, all variable and closeh' allied (six are here 

 listed from Kaslo), and as the falcataria group is not before me in 

 large series, 1 will let the name stand for the present. I have described 

 the larva in Life Histories of North American Geometridte, LL'' 



DEILINIA ERYTHREMARIA Guenee, var. PACIFICARIA Packard. 



Fourteen specimens, May 30, flune 3, !), 13, Id, 20, July 4, 21 (F.ear 

 Lake, jVIr. Cockle), August 7. This is the western form of i njthi'e- 

 inavid^ slightl}' larger and more distinctly marked. I have described 

 the larvie in Life Histories of North American (xeometrida*, XL^'H1.'■ 



DEILINIA VARIOLARIA Guenee. 



Two specimens, June 24, July 25, and one from Mr. Cockle's collec- 

 tion, June 17. They are not in good condition, but appear referable 

 to this species. Mr. G. AV. Taylor has sent me a specimen agreeing 

 with the Kaslo ones as Cymatopliora xnlxiJharia Hulst from New Jers(>y. 

 However, in this case 1 prefer Mr. Cockle's determination, as I think 

 I see a fovea on the hind wings below, which makes the species a 

 DeUln'ia.
