SETAGROTIS VERNILIS Grote. 



Twenty-eight s[)eciinens, July 2, 27, 8(1, August 3, 5, «;, 11, 12, 13, 

 17, 18. Unit'oini aiul of a darker, ))lucr gray than specinicn.s from tlic 

 Sierra Nevada of California or from Vancouver Ishmd. There is no 

 tendeiu'v to the pinkish or oeherous tints. Tlie orhicuhir is <)hli(|ue, 

 elongate, sometimes very nmeh so, and conHueut with the lower angle 

 of the reniform. 



SETAGROTIS VOCALIS Grote. 



Five specimens, July 10, 24, August 5, 9. Smith erected the genus 

 Set((<j rot !s on two species, ^>A//^//)v>//.s' and c<>ngri(a^ defined hy haxing 

 the antennae with tufts of hairs instead of ciliate or simple. The 

 character is a weak one, but such as it is is exhibited equally l)y vocalw 

 Grote, placed in Xoctua by Smith. The s])gc[gh j^l^tni^ro/is and conyi'ua 

 are only variations of one form and both synon3niious with vocalis. 

 The Kaslo specimens, while too few to properly exhibit the species, 

 show a good range of variation, the black tip to the collar and basal 

 dash of fore Avings being present or absent. The tone of the wings is 

 very dark gray, darker than any other specimens before me. This is 

 the general tendenc}^ in the Kaslo moths, but it may be due in part to 

 the freshness of the specimens and may not be so noticeable after they 

 have been in the collection a few years. 



AGROTIS YPSILON Rottemburg. 



Five specimens, August 1, 5, 6, 7. 



PERIDROMA OCCULTA Linnaeus. 



Seven hundred and forty-seven specimens, July 21, 25, August 1, 3, 

 6, 7, 15, 16, 18, 20 (West Robson), 21 (Revelstoke). Eggs were 

 obtained from captive moths and the larva? all hibernated. A few 

 were, however, forced to the last stage, so I am able to give the full 

 life history. Six stages, the normal number, are here described, 

 though most of the larva? interpolated a stage between the third and 

 fourth and between the fourth and tifth, caused by the tendency they 

 have to remain small till the winter is passed. 



Eggn. — Laid in a high pile several layers deep centrally. Two-thirds 

 spherical, spheroidally flattened, base flat; ribs about 2(>, diminishing 

 above, narrow, not markedly raised, joined by cross-stria' about as 

 distinct as themselves which form cells twice as wide as high, rounded, 

 the cell areas concave and indenting the ribs. Vertex finely reticulate 

 about the niicropylar rosette, which is slightly raised, l^ilc yellow: 

 diameter, 0.7 mm. 



Stage I. — Head bilobed, ])ale brown, black .spots on the tubercles 

 and small mottlings on the lobes above. Bodv normal, joint 12 slightly
