THE CANADIAN ENTOMOLOGIST. 63 



Second (later), a form precisely like the violacea of W. Virginia, but with 

 the female never brown. Third (still later), a form with faint markings 

 corresponding to the neglecta of W. Virginia ; occasionally in midsummer 

 large specimens of this are taken, and these I have considered Pseudar- 

 giolus. 



In all these places the earliest forms, or those called violacea and 

 Lucia, have the disc of the upper surface of the fore wings of the female 

 blue (excepting, of course, the brown females of the southern violacea), 

 untinged or scarcely tinged with white ; while the later forms always have 

 a whitish blotch or dash on the fore wings of the female. 



In California and Oregon three forms occur, but at what seasons I 

 cannot say ; two of these altogether correspond to the Psendargiolus and 

 fieglecta of the East, while the third (Piasus) is as large as the former and 

 has much heavier markings beneath, but the females are strongly marked 

 with white on the upper surface of the fore wings.* 



With this last exception, the specimens of Cyaniris in any one locality 

 seem to become larger, more lightly marked beneath and to show a 

 stronger tendency to paleness on the upper surface of the female as the 

 season advances. In view of this, and of the known relationship of C. 

 violacea and C. Pseudargiolus in W. Virginia, may it not be possible that 

 there is but a single species of Cyaniris in N. America ? For this, it is 

 necessary to assume some such hypothesis as the following, which is 

 suggested solely in the hope of stimulating investigation and arriving at 

 perfect knowledge : That in W. Virginia the first brood of this single species 

 appears as violacea with both brown and blue females; the succeeding broods 

 as Pseudargiolus, with occasionally (perhaps in seasons unfavorable for the 

 growth of the larva or its food-plant) a few individuals of smaller size 

 (neglecta). That in New York and Ontario, the first brood appears as 

 violacea with only blue females ; and the succeeding broods as neglecta 

 with occasionally a few larger specimens (Pseudargiolus ) ; this being the 

 centre of the latitudinal range of the insect, the distinction between the 

 broods would appear less marked than elsewhere. That in New England 

 and further north the first brood appears as Lucia and violacea — the earlier 

 individuals of the brood Lucia, the later violacea, just as the first brood 



* A species of Cyaniris exists in Western Texas, but I possess only females. 

 These resemble ft neglecta more closely than any other of the known forms, but are 

 much paler throughout. They were taken between the middle of September and 

 the middle of October.
