COLIAS II., III. 



ner's Anthyale, I have takou at ('()all)urgli. and have received both IVoin Texas 

 and Nova Scotia. It is characterized by very narrow borders, restricted on costa, 

 and by tlie conspicuous markings of the under side. A more diminutive pair, 

 but less aberrant, I have in my collection, the male expanding 1.3 incli and the 

 female but 1.2, captured in a meadow at Newburgh, N. Y. The female (Fig. 7, 

 PI. 3.), in which the discal spot of primaries projects a spur towai-ds the border, 

 was bred hy me at Coalljurgh, as was the other, in which the border is inmiacu- 

 late. Mr. Keakirt (Proc. Eut. Soc. IV., p. 219) mentions an example in which 

 the connection of the discal spot with the border was complete, as being in the 

 collection of tiu' Entomological Society; and Mr. Lintner (same work, vol. III., 

 p. 55) describes a female with immaculate border. Mr. Reakirt also speaks of 

 one in which the border takes the form of the " dog's head " characteristic 

 of C. Ccesonia, a variation which I myself have not observed in the present spe- 

 cies, but which does sometimes appear in the female Eurytheme, and is indicative 

 of the generic affinity of the two species. 



By inclosing the females of Phllodice, at the proper season, with a plant of 

 growing clover, eggs are readily obtained, and in this way I have I'epeatedly 

 raised the larviu. In such cases the parent is carefully pi'eserved for comparison 

 with its ])rogeny. Sometime.s, out of a l)r()od. the variation from the mother has 

 been unnoliceal)le, but in other cases very great, and this might well lae owing 

 to the dillerence between the parents. So a pale sulphur-colored female will pro- 

 duce some like itself and some of a deep yellow, etc. In the few instances in 

 which I have taken pairs in coitu, there was a close resemblance between them 

 in color and markings, but many observations are required to deduce any rule 

 therefrom as to like seeking like. Albinism is confined to the female, and ex- 

 amples are not uncommon in the held. Of course, these unite with yellow 

 males, and the product is partly albino and partly yellow, or it may be all yel- 

 low. In one instance I had five butterflies from eggs laid by an albino, and there 

 residted one male and four yellow females, no albino. In another case of four 

 females one was an albino. Mr. Mead has met with similar results, and neither 

 of us have known an albino to be j)roduced from the eggs of a yellow female. 

 The yellow females raised by me from albinos have all resembled one another in 

 this, that the under sm'face of secondaries has been densely coated with gray 

 scales, giving a peculiar and mealy appearance, and nearly all of both sexes have 

 had conspicuous double discal spots on the under side of secondaries, as repre- 

 sented in Fig. 2, PI. 3. 



The mature caterpillars differ in that some have a series of black spots beneath 

 the lateral band, while in others there is no trace of this ; but the same brood 

 will exhibit both varieties. The deepest colored examples of the butterfly which
