leaves of Scirpits atroi'ircns, Cincinnati, Ohio. Type and par- 

 atypes in writer's collection, paratype in collection of the Acad- 

 emy of Natural Sciences oi Philadelphia. 



The larvae begin to mine early in April. The mine extends 

 toward the tip of the leaf, beginning as a small transparent 

 blotch, with an opening on the under side of the leaf ; following 

 this is a linear green portion with sides nearly parallel, in which 

 the leaf substance is not eaten ; beyond this the mine expands 

 and becomes larger and semi-transparent. When ready to 

 pupate, the larva leaves the mine through a circular hole in 

 the upper side of the linear green portion. Larva whitish with 

 head black, thoracic plate dark brown, a brown spot on pos- 

 terior half of 9 and anterior half of 10. The imagoes emerge 

 in early June. 



This species is most easily distinguished by the thickened 

 dark palpi with sharply contrasting whitish apical half of the 

 third segment. 



Telphusa agrifolia n. sp. 



Palpi with second segment dark gray, irrorated, with inner side 

 and sometimes extreme tip whitish, third segment black, sometimes 

 with an indistinct whitish annulus near tip. Face gray, head blackish, 

 irrorated ; antennae black, with gray annulations. 



Fore wings with large patches of raised scales; ground color brown- 

 ish black, sometimes with golden brown reflections, especially in the 

 apical half, and sometimes unevenly dusted with pale brownish and 

 whitish scales. 



In one form an oblique whitish band crosses from basal fourth of 

 costa to near middle of dorsum, and follows the dorsum, but is inter- 

 rupted just before the tornus by an extension of ground color to the 

 margin; at the tornus it curves upwards and ends beneath the apex: 

 its shape and position are almost exactly those of the white band in 

 T. lonyifasciella Clemens. An inwardly oblique irregular line of paler 

 scales sometimes crosses the wing from apical third of costa to just 

 beyond the middle of the dorsum. The ground color is darkest im- 

 mediately before the oblique band, and before the curved portion of 

 the whitish area beneath the apex. 



In the more common form, the white is almost everywhere replaced 

 by dull blackish blue; a longitudinal streak of whitish scales some- 

 times remains just below basal fourth of costa; a few pale scales 

 follow the inner edge of the curved portion beneath the apev 



Three darker spots along costa in apical third, a dark patch at apex.
