g-oklen fti.scia is an ag-g-regiition of blark scales. Cilia golden white with 

 a thin Ijlack line parallel with the dorsal edge. 



Hindwings and cilia white. Abdomen sparsely scaled, yellowish, 

 with the scales silvery. Legs silvery, anterior tibia3 and tarsi and 

 posterior tarsi fuscous on the outside. 



Alar expanse, 5 mm. 



Described from a single specimen, reared from GiicttardiL ellcptlca^ 

 coUected at Palm Beach, Florida, by Dr. Dyar. 



Type.—^o. 4950, U.S.N.M. 



IJar^•a first makes a crooked narrow mine with the black f rass in a 

 continuous central line. Then the mine ))roadens out in an underside 

 blotch, visible about as nuich on ui)pcr side and usually confined 

 between two veins, which makes it more or less quadrangular, often 

 entirely obliterating the early part of the mine. 



Larva, when mature, is about 3.5 mm. long, somewhat flattened. 

 It leaves its mine through a slit on the underside and spins its snow- 

 white cocoon in a small fold at the edge of the leaf, under Init few 

 longitudinal silken threads. The food plant was kindly determined 

 by Mr. C. L. Pollard, of the U. S. National Museum. 



PODIASA, new genus. 

 (Type, FudUisd diiucucceUa, Busck.) 



Antennas a little longer than forewing, simple, basal joint flattened 

 to form a large eye cap. Labial palpi long, curved, smooth, terminal 

 joint as long as second. Maxillary palpi obsolete. Tongue present, 

 weak. Face and head smooth. Anterior wings ovate, obtusely rounded 

 at apex. Hind wings elongate ovate, obtusel}^ rounded at apex. Pos- 

 terior tibite and beginning of tarsi with heavy bunches of hairs above 

 and l>elow. The moth sits with the hinder part obliquely raised from 

 the surface, face closely tipplied to it, forelegs stretched forward in 

 front and wings roofed over the l)ody. Antennae extended along the 

 body under the wings and reaching a little outside the apex of these. 



Venation. — Fore wings: 11 veins, 5 absent, all separate, 7 to costa; 

 above the end of the cell is a secondary cell which emits veins *,) and 10; 

 lb simple. Hind wings: S veins, all separate. 



In spite of the totally different wing form and the presence of lal»ial 

 palpi, the genus reminds one strongh" of Leucoptera in general habitus, 

 as in mine and cocoon, but its true affinities are uncertain to me. 



PODIASA CHIOCOCCELLA, new species. 

 (Plate I, lig. 12.; 



Antennas yellowish silvery, light fuscous toward tip, basal joint 

 with large silvery white e3"e cap. Labial palpi silvery white. Eyes 

 deep black both in living and in dead specimens. Head and thorax
