that I can detect no "pale ocherous, slightly scalloped line at the base 

 of the fringe " and there are small blackish .spots at the ends of the 

 veins not mentioned by Packard. The lines vary nuich in distinct- 

 ness. 1 shall describe the larvte in Life Histories of North American 

 Geometrida?, LXV. 



EUCROSTIS VIRIDIPENNATA Hulst. 



No specimens; one in Mr. Cockle's collection. 1 iiave described the 

 larva in Life Histories of North American Geometridte, XXVIII." 



SYNCHLORA RUBRIFRONTARIA Packard. 



One specimen, July 4, and one from Mr. Cockle's collection, June 

 26, 1902, essentially like eastern specimens. 



APLODES RUBRIFRONTARIA Packard, var. DARWINIATA, new variety. 



Sixteen specimens, June 9, 16, 20, 23, 25, 30, July 4, 19, August 3, 

 5, 6, 7. The dates indicate two broods. T am dou})tful about the 

 standing of this form. It looks different from eastern ruhr if rout aria, 

 being larger, but I can not find any differential character that seems 

 constant. Doctor Packard says:* '"lam unable to detect any differ- 

 ences between the Pacific coast and Atlantic coast individuals in 

 the markings or colors." Yet his description of the larva states it to 

 be green, whereas the Kaslo ones are brown. I incline to the opinion 

 that there are two species; certainl}- there seems enough difference to 

 warrant racial distinction. Besides the larger size vasiy be mentioned 

 a tendency to have red points in the fringe at the ends of the veins 

 and the occasional presence of red-brown discal dots on all wings. 

 The white dorsal spots on the abdomen are narrowly circled with red, 

 not overspread with that color even in the females. Mr. Cockk^ had 

 the species named Anaplode-s jjistacearia Packard in hi.> collection, l)ut 

 this is erroneous, as the male has a hair pencil on the hind tibiiv and 

 dorsal a])doniinal spots. I shall describe the larvic in Life Histories 

 of North American Geometrida% LVII.

ORTHOFIDONIA SEMICLARATA Walker. 



Six specimens. May 29, 81, June 1, 11 (Hetcher's ranch). A few 

 eggs were obtained from a captive female, but the little larva failed 

 to feed. 



Egg. — Elliptical, distinctly flattened above and below, the ffatten- 

 ings not quite reaching the edge which is rounded; ends rounded, r.ot 

 truncate, depression of antemicropylar end not marked. Perfectly
