rated from another costal blotch beyond it, nearer to the apex. The cilia are 

 white, except immediately beneath the extreme apex, where they are dark 

 ferruginous brown. The outer half of the costal margin of the second lobe is 

 dark ferruginous brown, and this colour runs thence through the cilia imme- 

 diately beneath the extreme apex of this lobe; all of the remaining cilia are 

 snow-white. 



"Posterior wings dusted w ith cinereous brown ; the cilia of the same colour, 

 the third lobe only being slightly paler towards the base. 



"The abdomen and legs snow'-whitc, the two anterior pairs tinged with 

 brown on their inner sides. 



"Expanse 16 millims." 



Distribution: Type locality Mt. Sha.sta, Cal. The types were 

 taken in August. The only other specimens we have seen were taken by 

 Kellicott, in New York. There is one in the Fernald collection and 

 one in the National Museum, the latter dated March. 



There are four "types" in the Fernald collection, all males, and 

 one other specimen which appears to be from Walsingham. The 

 single specimen without data which is labelled with Kellicott's name 

 completes the series. We have at hand the single specimen belonging 

 to the National Museum which was also collected by Kellicott, and 

 which presumably came from Buffalo, N. Y., though it is without a 

 locality label. This distribution seerns very peculiar, but the species 

 will probably be found more widely distributed in Canada than is now- 

 known, or it may be the form taken in the southern extremities of the 

 range. The known distribution of dcdn'is Meyrick does not substan- 

 tiate the latter alternative, and influences us to treat declivis as a form. 



Kellicott reared the species from larvae eating the leaves of Soli- 

 dago sp., and at length published a description of the larva and pupa. 

 This is quoted by Fernald in the "Pterophoridae of North America." 

 apparently from the Bulletin of the Buffalo Society. We have no 

 original copy of Kellicott's description and so repeat Fernald's quo- 

 tation. We have carefully verified the identification of Kellicott's 

 species by sending the National Museum specimen to Meyrick for 

 comparison v.'ith Walsingham's type, and also by personal comparison 

 with the paratypes in the Fernald collection. 



"T'.'.c larva feed? upon different species of SoUdago. The first examples 

 were noticed on May 30. At this time they were found only on the under side 

 of the leaves, later they occur on the upper as well. As a rule, they lie close 

 to and parallel with the mid-vein. At least \^ hile young they eat out the paren- 

 chyma, leaving the epidermis.
