white, palpi white, antennae annulated black and white, club 

 black tipped with ferruginous. 



Conclusion A careful comparison of these descriptions will 

 show that the specimens described had only such minute dif- 

 ferences as could be expected from different sections and 

 different seasons. In fact there is as much or more difference 

 between our description and the others as there is between 

 them. If they are all legitimate we would be justified in giv- 

 ing still another name to our set of specimens. 



We might conclude to call this butterfly leda, the descrip- 

 tion of which most nearly approaches our specimens, with a 

 lowland form clytie and a fall form ines. This, to our minds 

 would be as justifiable as Edwards' fine differentiation of the 

 eastern pseudargiolus forms. Clytie has apparently a distinct 

 orange spot on anal angle, while our specimens show only a 

 minute orange patch in the best. In clytie the thread-like line 

 along under edge of wings is red, while in ours it is brown. 

 And finally clytie has an almost microscopic wholly white an- 

 terior tail as against our black tipped with white. Ines, on the 

 other hand, is not so fully colored as our specimens. The red 

 of the extra^discal line on under side disappears except for 

 some ferruginous scales on certain specimens. Other minute 

 color details also seem to be subdued as might easily occur 

 in fall specimens. These differences, however, are really so 

 minute that we consider even form names a superfluity. 



Thecla clytie was described in 1877. Leda and ines were 

 described in 1882. Mr. Aaron has stated that clytie might 

 possibly be adria Hewitson. Until this is demonstrated by 

 some one, we believe that the synonymy of this butterfly is : 

 Thecla clytie Edwards. 

 Syn. leda Edwards. 

 Syn. ines Edwards. 



ERISTALIS OESTRACEUS L. a North American insect. Mr. E. E. Aus- 

 ten finds that E. (Syrphus) oestriformis Walker, described from the 

 Albany River, Ontario, is a synonym of Linnaeus' oestraceus. (Ent. 

 Mo. Mag., March, 1911, pp. 63-64). ,
