LIST OF A COLLECTION OF DIURNAL LEPID- 

 OPTERA FROM SOUTHERN TEXAS.<^ 



By E. M. and S. F. Aaron. 



This collection, made bv S. F. Aaron, from March 15th to Septem- 

 ber loth, in the Gulf region near Corpus Christi, is rich in species, 

 some of which are scarcely known in collections, a few heretofore un- 

 described, and in many cases the series of intergrades have proved to 

 be very complete. We have felt that notes thereon would prove of 

 much interest to students of the North American fauna. 



Papilio Philenor, L. Moderately common. 



Papilio Asterias, Fab. Occasional. 



Papilio Palamedes, Dru. Occasional on the Guadeloupe River, 

 not seen south thereof 



Papilio Thoas, L. 

 var. — Cresphontes, Cram. Common. The typical form 



Thoas, though occasionally found in Texas, was not taken. Cres- 

 phontes, the common form in the U. S., maybe readily told by the 

 macular central band on the primaries; this band is a connected bar in 

 typical Thoas. Careful comparison of all illustrations of these forms, 

 and of a series of both, assures us that they can not be separated 

 specifically. 



Pieris Monuste, L. Common. 



Pieris Protodice, Bd.-Lec. Common. 



Nathalis lole, Boisd. Very common. 



The variety Irene \ which Fitch separated on account of the presence 

 of the black band on internal edge of primaries beneath, the absence 

 of the central dot on same surface, and the broader shade of orange 

 towards base,) was taken in considerable numbers. With these and 

 the typical form many intermediate grades were taken, in fact the inter- 

 grades contained by far the greater number of specimens. 



Anthocharis Genutia, Fab. Common on the prairies during 

 the first week in April. 



Callidryas Eubule, L Occasional. 



These specimens from Texas, like those brought from Mt. Graham, 

 Arizona, by Mr. Morrison, would admirably fill the position of connect- 

 ing links between Eubule and Sennce if such were needed between 

 forms separated on inconstant characters. Mr. Butler in his Exotic 

 Lepidoptera has undertaken to separate these species on what seems to 

 us very insufficient grounds.
