Chilo placidellus Kearfott, Proc. U. S. Nat. Mus. xxx, 392, 1908. 



Mr. Haimbach has presented a type specimen to the National 

 Museum. I take pleasure in dedicating the new genus to him. 



Genus DIATR/EA Guilding. 



Sir G. F. Ilampson describes this genus as having a conical 

 protruding front; but I am unable to verify this statement. 

 All the specimens of Diatra a sac char alls that I have seen have 

 the front rounded and not exceeding the eyes. I am therefore 

 obliged to correct the generic diagnosis in this respect. T refer 

 here the following North American species only : 



Diatraea saccharalis Fabricius. 



Diatraea parallela Kearfott. 



Diatraea squamulellus Zeller. 



Genus IESTA, new. 



Mind wing with vein 6 from the upper angle of the cell; fore wing^ 

 with veins 7 and 10 from the cell; palpi extending a little over the 

 length of the head ; fore wings with veins 8, 9, 10 stalked, 7 from the 

 cell; front rounded and not prominent: proboscis minute; vein 11 

 anastomosing with 12. 



lesta lisetta, new species. 



Body and fore wing straw color, the veins narrowly lined in brown ; 

 discal and terminal intervenular dots black ; two oblique narrow brown 

 parallel outer lines. Hind wings whitish, without markings. Expanse, 

 16 mm. 



Two specimens, Dade City, Fla., from Mr. F. A. Merrick. 



TypeNo. 12211, U. S. Nat. Mus. 



Family COSSID.*:. 

 Hypopta francesca, new speeies. 



Gray: whitish cinereous, reticulate with blackish; the recticttlati6ns 

 are uniformly distributed. broad, traiiM erse, partly confluent in trans- 

 verse lines, which are most obvious subbasally and subterminally. Hind 

 wing entirely blackish gray. Beneath blackish gray, the reticulations 

 showing on a lighter field on the cost.T of both wings and continuously 

 along both sides of vein lr from base to margin: this curved gray 



stripe is mottled with bars of da'rk gray. Expanse, 21 to 23 mm. 

 Two specimens, Fort Meade, Fla., from Mr. F. A. Merrick.
