No. 2305. ON SOME FOREST LEPIDOPTERA—HEINRICH. 67 



rior of the seta (LI), remote, on a level with incision of dorsal hind 

 margin. Ocellar setae well separated; 01 equidistant from and 

 ventrad to Ocelli II and ///; 02 closely approximate and directly 

 ventrad to Ocellus /; 03 ventrad to 02, remote, equidistant from 02 

 and hypostomal ridge ; puncture Oa obscure, nearly obsolete, approx- 

 imate and posterior to Ocellus VI. Subocellar setae triangular 

 placed; S02 and 803 closely approximate; puncture SOa anterior 

 to and equidistant from S02 and SOS. Genal seta (Gl ) and puncture 

 (Ga) situated on middle of the ventral surface of the epicranium, 

 well separated; seta anterior to the puncture. 



Labrum with anterior and lateral margins evenly rounded, median 

 incision broadly triangular but shallow. Seta III, M2, and MS 

 triangularly placed; M2 postero-laterad of Ml; Ml and M2 on a 

 line respectively with La2 and Lai; MS and LaS on a Ime just 

 behind the anterior margin of the labrum; distance separating them 

 less than that between La2 and LaS or Ml and MS. 



Epipharyngeal shield conspicuous and sharply defined; rather 

 large; nearly a perfect rectangle, slightly rounded posteriorly. Epi- 

 pharyngeal setae closely approximate; triangularly grouped near 

 anterior margin of epipharynx; long, pointed, moderately broad. 



Maxillulae normal. 



L'lrvalhahits. — Leaf -miner throughout feeding period; frass voided 

 outside the mine. 



This genus is close to and derived from Recurvaria. In a great 

 many of the species now listed under the latter genus veins 5 and 6 

 of the hind wings are weak. In R. elacMsteUa Busck they are both 

 absent. But all have 2 and 7 of hind wing strong and the forewing 

 wider at the end of the cell and the cell itself unconstricted between 

 5 and 6. Evijjpe pollostella Busck (also very probably a leaf miner) 

 belongs in Tosca on venational characters and will probably have to 

 be referred there although the male genitalia differ in one striking de- 

 tail; in pollostella the harps are entirely lacking. The genus Evippe 

 itself should be limited to those species having both 4 and 5 of fore- 

 wings present and comiate or stalked. 



The new genus differs from Recurvaria most strikingly in the larva, 

 the diagnostic characters of which are the close approximation of 

 setae Pi and P2, the position of puncture Ad^a behind Aclrf2 rather 

 than between it and Adfl , the linear Tortricid-like arrangement of 

 setae Al, A2, A3, and LI and the pentagonal frons reaching to the 

 incision of the dorsal hind margin. Neahjda, another leaf-mining 

 Gelechiid genus, has a similar frons and also an even more flattened 

 head but the setal arrangement is quite different. Tosca differs from 

 Recurvaria also in an important genitalic character. In Recurvaria 

 the harps are consistently and strikingly assymmetrical as are also 

 the posterolateral projections (or flaps) of the tegumen whenever
