Diatraea grandiosella, new species. 

 ^^ 



A single large female differs from the series of lineolata in its 

 brownish color, without any yellow tint. The linings on the veins 

 and between are very distinct ; terminal dots minute, black ; discal dot 

 obsolete. The front is smooth, without prominence. Hind wings soiled 

 white. 



One female, Guadalajara, Mexico (Schaus collection). 



Type, No. 13619, U. S. National Museum. 



This may be a variation of lineosella, but it does not match 

 any in the series. % In lineolata when the veins are strongly 

 lined the intravenular streaks are less strongly marked. In 

 grandiosella, all are alike, heavily marked. 



r Diatraea pallidostricta, new species. 



Front conically protuberant, but without any point or ridge. Wings 

 as in lineolata, the linings indistinct and blurred, the whitish discal 

 ray strong, broad and contrasted. Discal dot minute ; terminal dots 

 absent. Hind wing white. 



One female, Sao Paulo, Brazil (Schaus collection). 

 Type, No. 13620, U. S. National Museum. 



W' 



Diatraea angustella, new species. 



The front is smooth, roundedly protuberant. Wings narrow, pointed 

 at apex, much as in lineolata but darker, the veins strongly relieved 

 in brown, the intervenular streaks broad and diffused, sometimes en- 

 tirely filling the spaces between the veins. No terminal dots. Discal 

 dot small, sometimes absent. Hind wings white, slightly soiled in the 

 male, faintly yellowish in the female. 



Two males, ten females, Castro, Parana, Brazil (Schaus 

 collection). 



Type, No. 13621, U. S. National Museum. 



Diatraea bellifactella, new species. 



Front with a cone and transverse chitinous ridge. Wings moder- 

 ately broad, the apices depressed. Pale straw color, the veins strongly 

 lined in brown ; a brown shade from apex towards end of cell, in the 

 male continued across wing by thickenings of the lines on the veins; 

 an outer parallel row of thickenings oblique from middle of outer 

 margin to middle of inner margin ; streaks between the veins linear, 

 not distinct; discal and terminal dots small, blackish. Hind wing 

 soiled white in both sexes.
