in E.ctemataria, especially in the female. Hind wings large, with a prominent 

 angle on the first median venule, even with the tip of the abdomen. Venation 

 as in Drepanodes, but a subcostal cell present, and the discal venules are not 

 curved as in Drepanodes. Hind legs with the tibiae very long and swollen, 

 with a fan-like tuft of hairs on the inner edge, often folded up and not visible; 

 tarsi about one-third as long as the tibia'. Abdomen long and slender. 

 Coloration much as in Drepanodes. 



The simple ciliated male antenna?, falcate fore wings, the prominent 

 angle in the hind wings, and the large, swollen, tufted hind tibia', as well as 

 the narrow front of the head, are the distinguishing marks of this easily 

 recognizable genus. In the narrow front of the head and the simple antennse, 

 this genus approaches Urania more closely than any other phalaenid moth. 



Larva. — Ramiform, variously tuberculated, with the third thoracic seg- 

 ment either tuberculated or swollen ; the body rather thick ; head not wider 

 than the body. Pupa pale brown, mottled with red, or quite uniformly 

 reddish-brown. — (Described from Abbot's MS. drawings.) 



Synojms of the Sjiecies. 



Whit ish-ochreous, with three subapical black spots E.falcata. 



Fawn-colored, both liues beut outward near the inner edge E. mibilata. 



A costo-apical, triangular spot; the line on the hind wings much beut E. furciferata. 



Outer edge of the wings entire ; wings clear E. transversata. 



Outer edge of the wings slightly scalloped ; wings mottled. E. clemataria.

1 9. — A slighter moth than E. transversata, with the wings similarly 

 angulated, and the apex of the fore wings rather more falcate than in E. 

 transversata. The male antennas slightly slenderer than in E. transversata. 

 Pale ochreous; head, body, and wings of the same hue. Fore wings with 

 no lines, and with only a few scattered blackish speckles, a conspicuous black 

 discal dot, and three subapical black spots, one just behind the costal edge. 

 Hind wings with a few scattered specks and a distinct black discal dot. 

 Beneath marked just as above, the three subapical and discal spots being 

 reproduced. Wings a little more densely speckled with black, and the fore 

 wings a little deeper ochreous. 



Length of body, 0.65; of fore wing, 0.82; expanse of wings, 1.70 inches.

This fine species may be at once known by the very acute falcate apex,
