angle is diffuse; comis is larger, with a certain tendency to green, the 

 spot at anal angle of primaries smaller, concrete, cspecialh^ marked in 

 the females. The male genitalia offer no sharp contrast. I will now 

 refer to the names proposed by Professor Smith. 



1. circumcincta Smith. This is obvious!}^ on\y a very dark form of 

 stricta. I was in error in referring it to olivacea. The Kootenai form 

 of stricta is not dark, judging from the single specimen I obtained as 

 I was leaving the place, though it might pass for emnaharhia Grote. 

 Professor Smith's form is from the Sierra Nevada of California. 



2. rectilinea Smith. The female types before me are from Sierra 

 Nevada, California. The}^ are normal females of coiaU. 



3. luclna Smith, altua Smith, inegarena Smith. These are admitted 

 b}" the author to be but races of olivacea. They should not have been 

 listed as species. Altua and megarena are from the same faunai region 

 and should be made synonymous. 



4. davena Smith. I have the male type. I can not match it exactly 

 in the same sex from the Kaslo catch, though the faunai region is the 

 same. It is a somewhat aberrant specimen. .V male comis from 

 Wellington, Vancouver Island, is nearly its exact mate and a female 

 from Kaslo represents the same form. Smith's slide of the male 

 genitalia shows some differences. The piece is narrower at the end, 

 less spinose. The single specimen, however, is not convincing and I 

 am inclined to view^ it as varietal. 



6. ohiigra Smith. The female ty^Q before me is onh' comis Grote. 



6. jpetita Smith. This was described from one male and three 

 females. I believe the male w^as comis.^ the females olivacea. The 

 latter I can match from Wellington and the males accompanying them 

 resemble altua and do not show the peculiar character attributed to 

 the genital structures in Smith's figure. This slide is before me and 

 is only, I think, a distorted specimen. The spine that stands up so 

 strangely has been misplaced from its normal position by pressure, 

 while its apparent slenderness is due to its being seen edgeways. If 

 replaced, I think nothing different from the usual comis form would 

 be seen. 



Besides these, Smith has described vau-media and incurva., which 

 he refers in this neighborhood. They are not before me, but I have 

 little doubt that vau-media is olivacea and will replace the name 

 altaa.^ while incurva is compared with anguina and therefore is prob- 

 ably not refei'able to this group. 



Allowing now every possible latitude for geographical forms, I 

 place the names thus: 



OLIVACEA Morrison Atlantic region. 



obscurior Smith. 



race lucina Smith Western prairies. 



race altua Smith (=? vau-media Smith) Rocky Mountains. 



megarena Smith. 

 race petita Smith Pacific coast and mountains.
