as Chambers's descriptions and especially his figures are not always 

 to be relied on, it would be unwise in the absence of any authen- 

 tic material to unite the two genera on the present evidence, the more 

 so because very small differences in structure will rightly differentiate 

 genera in this family and because the specific descriptions clearly 

 represent two different species. 



I therefore leave the genus Eido as unrecognized at present, and the 

 distinctive characters utilized in the generic table, being derived from 

 description and figure alone, are tentative only, and may prove of no 

 value on the discovery of the species, which should not be difficult.

Apical joint of the palpi snowy white, with a narrow brown ring at 

 the base; second joint white at its apex and on the inner surface; 

 grayish brown on the outer surface. Antennae grayish brown, an- 

 nulate with white. Head, thorax, and primaries grayish brown with 

 a row of yellowish ochreous spots around the apex of the wings at the 

 base of the cilia. 



Alar expanse. — -/,; inch; 14 to 15 mm. 



Captured in June in Kentucky. 



The above is Chambers's description; no such insect is at present 

 known to the writer, but it would seem easy to identify it, whenever 

 found, by the striking form and color of the labial palpi. 



5. Genus GERDANA, new. 



Labial palpi rather short, not reaching vertex: second joint some- 

 what thickened with scales, which are slightly roughened underneath 

 the tip; terminal joint shorter than second. Tongue long, scaled, 

 curled. Antennae a little longer than half the wing length, simple; 

 basal joint with pecten. Forewing elongate, ovate, apex not acutely 

 pointed, cell rather long: 12 veins: 7 and 8 stalked: 7 to termen; 3, 4, 

 and 5 approximate from end of cell; 2 distant. Hindwings as broad 

 as the forewings; costa excised from the middle; termen straight, 

 oblique; dorsum straight, inner angle well developed; 8 veins: 6 

 and 7 parallel, but flaring towards the tip; 3 and 4 connate or stalked; 

 5 nearest 4, cubital. 



Type. — Gerdana caritella Busck. 



Only one species is at present known. 



GERDANA CARITELLA, new species. 



Labial palpi deep saffron-yellow. Face. head, and thorax lighter 

 yellow. Forewings light yellov\ suffused with darker saffron-yellow ;
