of Paphia troglodyta, though I almost failed in this because of 

 absence of the food-plant here. To me the Catocalse are espe- 

 cially interesting, because so little is known of them. A certain 

 wind brings them and then they are gone, no one knows where. 

 I hope to hear more through the Entomological News con- 

 cerning this interesting group. 



Some old Forms of our Common Diurnals, with a few Remarks. 



By George A. Ehrman, Pittsburgh, Pa. 



The strange variations which occur among our common insects 

 are looked after by the specialist with equally as much interest 

 as new or undescribed species, as mother nature is not constant 

 in creating her offspring alike. I had the good fortune to cap- 

 ture a few exceedingly odd forms of our commoner species of 

 diurnals in my locality during the past few seasons, and I wish 

 to place them on record. 



Papilio turnus Linn. — A male has the color of the right pri- 

 mary replaced by pale buff almost white instead of the usual 

 yellow; it extends from the base to the black marginal band on 

 the outer edge, taking up that space from the inner margin to 

 the discal cell and extending upwards to the subcostal nervure; 

 the black on the outer marginal band in this space is paler, other- 

 wise the specimen is normal in structure and coloration. 



Papilio turnus dimorphic $ Glaucus Linn. — Two examples 

 that agree with the intermediate forms figured in Edw. Butt. N. 

 A. 2, pi. 5. and a third example that is the same as the general 

 run of Glaucus, but has a yellow body. 



Papilio asterias Fabr. — A male of the usual form, but smaller 

 in size, and the ocellus is without the pupil spot, hence it is blind- 

 eyed like Papilio machaon Linn, of Europe. 



Colias philodice Godt. — One male, normal on the upperside 

 excepting the secondaries, on which the upper discal nervure and 

 subcostal nervures are black; on underside of primaries there is 

 a dark smoky arch extending from the inner angle to the discal 

 cell. 



Argynnis bellona Fab. — One female which has the right hand 

 hindwing pale fulvous from discal cell to the outer edge of wing 

 on the upperside, and the black spots are very faint; the same
