Erycina p. Latreille, W. W. Smmders. 



Erycina, Diorina, and Zeonia p. Boisduval, Morisse. 



Ancylcris Hiibner. 



Body robust : hind wings moi-e or less produced into an elongated tail. 

 Head finely hairy, not tufted ; -widest in the males. 



Eyes large, lateral, naked. 



Antennce long, slender, the articulations scarcely distinct ; terminated by a long and gradually formed club, about 

 twice as thick as the middle of the antennae, gradually attenuated to the tip. 



Labial Palpi variable in length, scaly, porrected horizontally, or with the tip but very slightly elevated; 

 terminal joint slender, nearly naked. 

 Thorax robust, slightly clothed with hairs and scales. 



Fore Wings elongate triangular. The costal margin straight, or slightly emarginate along a considei-able 

 portion oi its middle ; apical angle generally rather acute. Apical margin elongated, sometimes three fourths 

 of tlie length of the costa, entire, and often convex. Hinder margin scarcely half the length of the costal, 

 also slightly convex. Postcostal vein with three branches : the first arising sliortly before the anterior 

 extremity of the discoidal cell ; the second considerably beyond the cell ; the third at a little distance beyond 

 the second. Upper disco-cellular obsolete : middle disco-cellular arising at a short distance beyond the first 

 branch of the postcostal vein, and generally a little in advance of the oi-igin of the upper discoidal vein, 

 short, transverse : lower disco-cellular much longer, also transverse, slightly curved, closing the discoidal cell 

 before the middle of the wing, by its union with the third branch of the median vein, close to, or but very 

 little bej'ond, its origin. 



Hind Winqs variable in form. The hinder margin produced in the middle into a more or less elongate tail ; the 

 entire length of which is traversed by the second branch of the median vein, the first and third branches of 

 which extend to its sides. Tiie costal vein extends nearly to the extremity of the costal margin. The precostal 

 vein short, very oblique, and arising at a rather considerable distance from the body, and running into the 

 dilated base or lobe of the wing. Postcostal vein arising much nearer the body than the precostal, branching 

 at a moderate distance from its base. The upper disco-cellular vein arising at a very short distance beyond 

 the branch, oblique, sliglitly curved : lower disco-cellular similarly curved and oblique, about twice the 

 length of the middle one, uniting with the third branch of the median vein at a very short distance beyond 

 its origin. 



Fore Legs of the male, small, scaly, depressed, with the sides thickly clothed with long hairs. Fore Legs of the
