[These notes were sent me by Mr. T. D. A. Cockerell with others 

 on certain well-known species which it did not seem worth while to 

 publish. I have seen the bred imagos of all except the first three and 

 last two ; the last two were determined by Sir G. F. Hampson. It 

 has been impossible to get the names of the food plants — Harrison G.

AN ABERRATION OF PAPILIO PHILENOR. 



By Archibald C. Weeks. 



(Plate VI.) 



Papilio philenor Linn., aberr. wasmuthii aberr. nov. 



This form, the type of which was exhibited by Mr. William Was- 

 muth at a meeting of the Brooklyn Entomological Society, held De- 

 cember 6, 1900, and a figure of which is shown herewith, was pro- 

 duced from one of two nearly matured philenor larvre taken by him 

 in the latter part of August, 1900, upon the Dutchman's Pipe plant 

 {^Aristolochia sipho) growing in front of his residence. Neither larva 

 displayed any characteristic, either in size or general appearance, to 

 distinguish one from the other nor from other larvae of the same spe- 

 cies. Shortly after their capture they pupated and together on the 

 same day, about the middle of September, emerged. One proved to 

 be an orthodox philenor, and the other so unusual a deviation from 

 the type as to warrant a special designation. Broadly stated, the ab- 

 erration consists, upon the upper side, of the extension inward between 

 the veins of the white marginal lunules to such a distance as in the 

 primaries to comprehend the entire submarginal row of white spots, 

 and in the secondaries to leave only a more or less faint line of sepa- 

 ration, increasing in fullness in the direction of the inner angle. In 

 the primaries the white indentations assume a sagittate form, the first 

 at the apex being narrower than, and half as long again as, any of the 

 others. In the secondaries the indentations are more nearly subquad- 

 rate. All indentations are separated by the veins, heavily bordered 

 with the ground color of the base and discal area, and the majority 

 of them are cleft by a narrow line paralleling the veins. The portion
