?. Vaginal j)late small, rounded; orifice a nari'ow transverse slit, placed some- 

 what towards the left side. 



Larvae not sufficieutly known, figured of lui/nhrls and nri//jcte. — Food-jilauts : 

 Vitis, Citriia, etc. 



Pupa : cylindrical, glossy ; head rounded ; labrum terminal ; tongue-case not 

 carinate ; head and thorax not punctured ; abdominal segments punctured at base ; 

 anterior femur visible ; cremaster elongate-conical, smooth, suddenly narrowed at 

 tip, which is bifid. 



Hab. Tropical and .Snbtro])ical America ; lugnbris oc('urring occasionally as far 

 north as Massachusetts. 



The genus stands as yet isolated. 



There is considerable sexual dimorphism and dichromatism in tliis genus. The 

 five species fall into two natural gronjis, which are as follows : 



I. E. f/onjon, fnedinm, and caeifer : 



S. A fold on subcostal vein of forewitig, ujijierside, covers tlie anterior jjiirt of 

 the cell and extends beyond the ajjex of the cell well npon the disc ; within the fold 

 there is a dense clothing of small white scales, besides a woolly mass of scale-hairs 

 (scent-organ). On the underside the cell is covered with small brown scales, and 

 is more or less distorted ; M" arising near the base, M' in middle. Abdomen witii 

 sides of tergites covered with woolly scaling. Hindtarsus strongly compressed, 

 scaling of up])er and ventral side long as on tibia. 



?. Normal, discal margin of forewing not denticulated. 



II. E. liigiihris and oei/petfi : 



Both sexes normal, distal margin of forewing more or less denticulated.
