186.").] 141 



Fore wings with a broad fold, extending to the middle of the costa. 

 closely appressedj at least three times longer than broad; costa straight, 

 tip moderately acute, apical margin rounded. The nervules given off 

 from the posterior end of the cell are bent towards each other, or are 

 somewhat aggregated. 



Head smooth, with ocelli at base of antennae. Antennae filiform, 

 simple. Labial palpi do not exceed the face, are curved, smooth, rather 

 slender, expanded towards the tip, the apical joint scarcely perceptible, 

 except in front. 



Euryptychia saligneana. — Fore wings white tinted with yellowish. The ba- 

 sal patch is dark brown. The wing beyond the basal patch is nearly white 

 varied with leaden-colored speckles and striped over the nervules with dull, 

 leaden-gray, transverse stripes, two of which near the anal angle form a white 

 ocelloid patch. Immediately interior to the ocelloid patch is a small black 

 spot, having a line of black atoms running into it, from above and beneath. 

 Below the apex, on the hind margin, is a triangular brown patch which is va- 

 ried with grayish and dotted with black in the middle and along the inner 

 edge. The costa is geminated with white and striped with brown. Hind wings 

 dark fuscous. 



I have before me a single specimen of the above insect, received 

 from my esteemed friend I3enj. D. Walsh of Hock Island. It was 

 bred by Mr. Walsh from a willow gall, a year or two ago. I have un- 

 fortunately mislaid the letter in which his account of it is written. 



The imago appears to me to differ from all the genera of PlicatEe to 

 a degree that warrants me to describe it as a new genera.
