 concave; lateral lobes poorly developed. Aedeagus stout, slightly 

 curved, bluntly pointed; vesica armed with a large patch of small 

 cornuti. Vinculum rounded, with prominent dorsoanterior process.

Type.—\].^.'^M. No. 52947. 



Type locality. — Henry, Putnam County, 111. 



Food plant. — Amorplia fruticosa L. 



Remarks. — Described from the $ type, 78 $ and 65 5 paratypes 

 all from the same locality. These are all reared specimens, bearing 

 May and June dates, from larvae collected by Murray O. Glenn. 



Paratypes in the collections of Murray O. Glenn, Magnolia, 111.; 

 H. H. Keifer, Sacramento, Calif. ; Dr. Annette F. Braun, Cincinnati, 

 Ohio. ; Los Angeles Museum ; and Canadain National Museum. 



In this species the males are strikingly darker and smaller and the 

 markings less contrasting than in the females. 



I am indebted to Mr. Glenn for the long series of reared specimens 

 which make up the type series. Some of the specimens were reared 

 by Mr. Glenn while others were reared in Washington from 

 larvae submitted by him. The specimens reared at Washington are 

 identical with those reared in Illinois, although the emergence dates 

 are earlier for the former than for the latter. 



Of this species Mr. Glenn writes, "The first emergence was June 4 

 (1938), and the heaviest from June 10-13. Pupation in the field 

 occurs immediately (after the larva matures) at the base of the 

 plant. In many instances this is the only place available as the 

 shrub is often completely surrounded by water, except for a small 

 hummock, about a foot in diameter, formed by the plant roots." 



This species may be separated readily from roMniella or lecon- 

 tella by the yellow discal spot of the fore wing.
