Annette Braun for all the above and for the text figure that accom- 

 panies this description. The Adams and Clermont County specimens 

 were reared by her from larvae feeding on leaves of RJiannnus lanceo- 

 lata and the three males from Champaign County were taken resting 

 on Rhanmus alnifolia. Regarding the Beaver Bond specimens 

 Doctor Braun writes as follows: 



The young larva makes a characteristic foUl in the leaf toward its tip, 

 by bringing the outer margin at one point close against the midrib ; feeding 

 takes place beyond the fold toward the tip of the leaf (fig. 1, A). As it 

 consumes the leaf in front of it the larva extends the fold backward toward 

 the base of the leaf (fig. 1, B). The larva is pale yellowish, rather translu- 

 cent, with head about the same color as the rest of the body. Pupa (in breed- 

 ing jar) in fold, usually at edge of leaf. These notes apply more particularly 

 to the first generation of larvae ; by the time the fall generation appears iu

September and October, the leaves are usually iu rather poor condition from 

 the feeding of other species, specially Apopthisis pullata and Ncpticuia rliani- 

 nicola, and the mode of feeding of the Anchijlopera is not as characteristic, 

 as the larva may feed at either end of the fold or irregularly. 



The species is easily recognized and not to be confused with any- 

 thing else in the genus except tlie western definitivana from which 

 it is at once separated by its shorter, stouter aedoeagus and differently 

 shaped harpe, the lower margin of the cucuUus being convex and 

 evently rounded in hrauni and distinctly concave in definitivana. 

 The uncus is also proportionally shorter in hrauni.

Through the kindness of Miss Braun we now have authentic speci- 

 mens of this species reared from larvae taken feeding on Spiraea
