27. TRYPANISMA Clemens 



Body and hind wing similar to Recurvaria. Fore wing with M a closer to M„ 

 M 3 and CUj stalked. Hind wing with R and M 1 stalked, R running to apex. 



Key to the species 



Head white 2. fagella,. 



Head suffused with fuscous 1. prudens. 



1. T. prudens Clemens. Head pale yellowish white; vertex with large, blackish 

 spots on most of the scales; second segment of palpus with two dark brown spots 

 on the outer side, or wholly dark, and third segment with rings. Antennae 

 slightly annulate. Thorax and fore wings powdery blackish, tinted with yellowish, 

 darker than T. fagella, with a small ochreous dot below base of costa; a patch 

 on middle of disc, often reaching inner margin, preceded by black dots in the cell, 

 and a postmedial band, strongly angulated or broken into costal and dorsal bars 

 as in T. fagella. Hind wing fuscous. 9 mm. (quinqueannulella Chambers.) 



May. The caterpillar forms a web on the under side of an oak leaf near the 

 tip, communicating by holes with the upper side where the caterpillar feeds. It 

 occurs in July and August. The pupa is formed in a slight cocoon in the leaf. 



District of Columbia; Pennsylvania; Ohio. 



2. T. fagella Busck. Head white. Antenna annulate with fuscous. Palpi with 

 only one faint annulation on second segment, and two on third. Thorax and fore 

 wing powdery light gray. Two circular blackish spots (at middle and en4 of cell) 

 in a cream-yellow shade, which reaches the inner margin at the middle; a larger 

 diffuse oblique streak at base of costal fringe and a spot on the inner margin 

 opposite it, both edged beyond with cream. Hind wing, with fringe, and abdomen 

 light silvery gray. 9 mm. 



Caterpillar similar to T. prudens; on beech. 

 District of Columbia. 



28. EVIPPE Chambers 

 (Phaetusa Chambers) 



Similar to Epithectis and Recurvaria. Fore wing with all veins present; M, 

 and M 3 connate or more often stalked; Cu t free, halfway between M 3 and Cu 2 , and 

 equally long. Hind wing (fig. 162) nearly as wide as fore wing, with slightly 

 produced apex, R sinuous and running to apex, M t lost, cell very weakly closed or 

 open, M 2 close to M 3 , which is almost connate with Cu t . 



The moths are superficially similar to Recurvaria dorsivittella, but have cleaner- 

 cut markings and lack the two black palpal bands of Recurvaria. 



1. E. prunifoliella Chambers. Palpi white, with base of second joint and extreme 

 tip of third blackish. Head and thorax white, with a blackish shade above antennas, 

 and black tegulae. Fore wing black, shading into dark gray on costa, powdery 

 toward apex along outer margin. Inner margin broadly white, with a twice-waved 

 upper boundary, which becomes diffuse at apex. A subterminal costal spot, more 

 or less distinct. 9 mm. 



May to June. Caterpillar under the folded tip of a leaf of plum or peach in 

 late fall; apparently a leaf -miner when young; rarely on soft maple. 



E. leuconota Zeller, a much smaller species, without any trace of the costal pale 

 spot, has been reported from Albany, New York.
