PARAGROTIS MAIMES Smith. 



One specimen, September 1> (Field). The species much resembles 

 Rhisagrotis jJdvicollis Smith, but differs in the color of the thorax and 

 in the generic character of having the male antenna; shortly serrate. 

 My single specimen from Field agrees with one kindly sent me by Mr. 

 F. H. Wolley Dod, from "■ Head of Pine Creek,-"' near Calgary, Alberta. 

 It should be noted that Mr. Dod's collection about Calgary may cover 

 two faunal regions. Calgary itself is in the prairie, and shows such a 

 fauna as would be expected, wdiile the locality " Head of Pine Creek" 

 must be in the foothills of the Rock}" Mountains, judging by the species 

 sent out with this label. 



PARAGROTIS BROCHA Morrison. 



Thirty-seven specimens, July 30, August 3, 4, 5, 6, 11, 12, 13, 15, 

 16, 17. 



PARAGROTIS PUNCTIGERA Walker. 



Eight hundred and eighty-eight specimens, July 19, 21, 25, 27, 

 August 5, 0, 7, 12, 13, 17, and three from Mr. Cockle's collection, 

 July 25, 1901, July 25, 1902, August 1, 1902. The mass of the speci- 

 mens fall between j;a,s^c>r(2Z«« Grote and Jin!s Smith. These are the 

 extreme forms. The series, when once sorted out, looks homogeneous 

 and uniform, though varying greatly in the amount of yellow powder- 

 ing on the lines and spots. The black line on the collar comes out 

 more or less distinctly, destrojang the value of this character in sepa- 

 rating species. The hind wings are dark brown in both sexes. I 

 think loya Smith is a variation of this type and perhaps some others 

 that now stand as good species. Mr. Cockle's specimens before me 

 are undersized and with ver}" little of the characteristic powdering, 

 and, without this series, I should never think of referring them to 

 punctigera. They come extremely near to the brown form of fociniis 

 mentioned below. A well-marked specimen in Mr. Cockle's collection 

 has been named compressijjennis Smith, but it does not appear to me to 

 agree with the type of that form which is before me. A brownish 

 specimen, also in Mr, Cockle's collection, has been named friahilis 

 Grote \^f acinus Smith, was meant, probably], but it does not agree with 

 Hampson's tigure and description of that form, which is otherwise
