(!lasjier I'luliiig in a process, or acnminate, with small and numerous friction-scales; 

 armature ditterent in most species (PI. XLVII. f. 10 — 19). Peuis-sheath either 

 with practically no armature, or ending in a long apical process (PI. Lllf. f. 32. 33). 



?. Vaginal ]ilate small, rounded; orifice a narrow transverse slit, placed some- 

 what towards the left side. 



Larvae uot sufficiently known, figured of lui/i//jrig and oci/jtcte. — Food-plants : 

 litis, Citrus, etc. 



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

 carinate ; head and thorax uot punctured; abdominal segments ]innetared at base ; 

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

 tip, which is bifid. 



Hab. Trojiical and Subtropical America ; lugabrix occurring occasionally as far 

 north as Massachnsetts. 



The genns stands as yet isolated. 



There is considerable sexual dimorphism and dichromatism in this genns. The 

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



I. E. goryon, taedinm, and cad/er : 



cJ. A fold on subcostal vein offorewing, ni)perside, covers the anterior part of 

 the cell and extends beyond the apex of the cell well upon the disc ; withiu 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 with 

 sides of tergites covered with woolly scaling. Hindtarsns strongly comiiressed, 

 scaling of uj)per and ventral side long as on tibia. 



?. Normal, discal margin offorewing not denticulated. 



II. E. Ingiibris and odjpcte : 



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