AMERICAN LEPIDOPTERA. 105 



we can imagine the margin to be abnormally drawn in. The neura- 

 tion is aberrant in consequence. The full secondaries have the cell 

 incompletely closed. Vein 5 is removed from 3 and 4 at base and 

 originates from the closure of the cell before the median fold. This 

 neuration agrees with that exhibited by what is here considered as a 

 second species with undivided wings, but what is in all probability 

 the normal female form of this remarkable genus. From all the 

 species described by Guenee ours differ at once by the absence of cos- 

 tal tufts; but the neuration agrees, on the whole, with Guenee's des- 

 cription, and I must consider our forms correctly referred here. 



Tortricodes bifidalis, Grote. — % .—Light, rather dull brown. Ou 

 eosta at base a trace of the basal half-line. T. a. line even, margining in- 

 wardly a diffuse deep brownish shade which extends over the median space 

 anteriorly and fades towards the linear median shade line. Reniform small, 

 pale centered, sometimes divided into two pale dots. T. p. line blackish, linear, 

 like median shade in appearance, slightly projected below costa, inwardly 

 curved at vein 1, a little irregular, less distinct towards internal margin. Sub- 

 terminal line very distinct at costa where it is brought into relief by pale 

 scales and forms a prominent exerted acute tooth on the upper lobe. The in- 

 ternal margin of the upper lobe shows a black dot at its middle, and the ex- 

 tremity of the fissure is touched with black. A blackish apical shade. Second- 

 aries fuscous with inconspicuous discal marks and double transverse lines 

 relieved by paler shades; beneath the discal dot is black and distinct and the 

 lines more evident; the inner black, denticulate. Head and appendages and 

 thorax above concolorous with primaries. Abdomen like secondaries with a 

 series of darker dorsal segmentary shades. Expanse, 25 m. m. 



Habitat, — Atlantic District (New York to Texas). 



I have taken this species at Hastings, N. Y., on June the 18th. 



Neither the present nor the following show any costal hair tuft on 

 on the primaries like that characterizing the Brazilian and West In- 

 dian species described by M, Guenee. Our species differs from the 

 description of T. orneodalis from Guadaloupe in many respects such 

 as color, the presence of the distinct subterminal line and in all the 

 details of the ornamentation and size. 



What appears a second species exists in the collection and occurs iu 

 the same localities, but at first sight, by its color and style of ornamen- 

 tation and size, this suggests an affinity with the preceding species. 

 And as I see that Guenee records his 2nd group of the genus as want- 

 ing the characteristic cut of the fore wings, I can consider this species 

 as not differing generically from T. bifidalis. 



There is no vestige of a cut on the primaries, which have the out-
