Genus XIII. NECYRIA. 



Necyeia Westwood. 



Body rather slender : wings large, entire, more or less glossed with metallic blue and green tints, and with blood- 

 red spots. 

 Head moderate-sized, hairy. 



Eyes naked. 



Labial Palpi small, very hairy : terminal joint minute, conical, not extending beyond the hairs of the face. 



Antenna} about half the length of the fore wings, slender, annulations indistinct ; terminated by an elongate rather 

 slender, gradually formed club, obtuse at the tip. 

 Thorax moderate-sized, hairy, especially at the sides. 



Fore Wings large, subtriangular. Costal margin nearly straight. Apical margin more than three fourths of the 

 length of tlie costal, entire, sliglitly convex, or nearly straight. Inner margin straight, and short. Veins 

 arranged as in Erycina: the middle disco-ceUular and the upper discoidal originating together, beyond the first 

 branch of the postcostal vein ; the postcostal being rather angulated at the place of their origin, the upper 

 discoidal appearing to form its apical portion. 



Hind Wings triangularly subovate. Costal margin slightly arched. Apical margin entire, convex ; anal angle 

 rounded, not produced into a point or tail. Anal margin scarcely forming a groove for the reception of the 

 abdomen. Veins arranged as in Erycina : the upper disco-cellular vein arising at a very short distance beyond 

 the branch of the postcostal, oblique ; lower disco-cellular uniting with the third branch of the median, close 

 beyond its origin, closing the discoidal cell at little more than one third of the length of the wing from its 

 base : the branches of tlie median vein are at the same distances apart as the discoidal and postcostal ones. 



Legs as in Ei-ycina. 



The two beautiful insects of which I have formed the present genus are very closely allied to Erycina in tlieir general cliaracters, as 

 well as in their colouring ; they do not exhibit, however, tiie regular transverse fascia; of the species of that genus, and the arrangement 

 of the brilliant metallic colouring of these insects is quite different from that of the EryciniB. The hind wings, also, have not the slightest 

 tendency to elongate into tails in the middle of the hinder margin, and the veins are consequently arranged at equal widths apart. 



The species inhabit Western Brazil and (Juito.
