 22, 25, 27, and September 2. The best date, or that on which 

 most specimens were collected, is August 20. 



Rhynchagrotis rufipectus Morr., August 18 ; one 

 male specimen of normal type in all paiticulars. The species 

 extends across the continent and occurs on the Pacific coast as 

 far south as Los Angeles. 



Pachnobia littoralis Packard, July 18 ; one male. The 

 specimen is unusually dark, the contrasts of the fore-wing well 

 marked, but the transverse lines incomplete and somewhat in- 

 definite. The species extends from Labrador into the Northern 

 Rocky Mountain region, and has not yet occurred south of 

 Colorado. 



Peridroma occulta Linn., August 5 (i) ; August 8(1); 

 September 2 (i). Apparently normal forms in all respects, 

 but two of the three are very badly marred. The species occurs 

 throughout the Northern and Eastern United States to Nova 

 Scotia and the Rocky Mountains of Colorado. 



Peridroma astricta Morr., August 4 (i); August 5 (i); 

 August 10 (i). All are females, in rather poor condition. In 

 this species and in the preceding the badly marred specimens 

 seem to have been papered while still alive, and the specimens 

 oviposited in their envelopes. The larvae hatched and appar- 

 ently devoured most of the body of their parent, before them- 

 selves perishing. The distribution is much as in the preceding 

 species. 



NOCTUA COLLARIS G. & R., August 16 and 22 ; two male 

 specimens. Both are large and rather dark forms, with the 

 collar and shade between the ordinary spots well defined ; but 

 the other markings tending to become obscure. This is the 

 most western record of this species. It is a typical northern 

 and eastern form. 



NoCTUA CLANDESTINA Harris, June 21 (2) ; July 20 (i) ; 

 July 24 (2); July 30 (i); August 8 (i); August 20 (i). All are 

 dark typical specimens, and vary only a little in size. A well
