ERYCINID^. 



Genus XXXVII. PARNES. 



Parnes E. Douhleday. 



Body very small, slender ; wings large, rounded, of a uniform dark colour above, with submarginal ocelli beneath. 

 Head as broad as the thorax, clothed with fine hairs, which are longest on the crown. 



Antenna more than half the length of the fore wings, rather robust, annulated with white ; terminated by a 

 long, gradually formed, compressed club, obtuse at the tip. 



Eyes large, naked. 



Labial Palpi small, compressed, elevated to about the height of one third of the eyes, not visible from above, 

 clothed beneath with long detached scales ; terminal joint small, slender, acute, and nearly naked. 

 Thorax rather small. 



Fo7-e Wings large, rounded, entire. Costal mai'gin strongly and regularly arched from the base to the apical 

 angle, which is obtuse. Apical margin convex, fringe very long. Costal vein not extending to half the length 

 of the fore wings. Postcostal vein with three branches ; the first arising at a considerable distance before the 

 anterior extremity of the discoidal cell, uniting with the costal vein for a short distance, and then branching 

 off, joining the costa nearly opposite to the exti'emity of the discoidal cell ; second branch of the postcostal 

 also arising before the extremity of the cell ; third branch short, arising at more than half the distance between 

 the cell and the tip of the wing, the terminal part of the vein running to the tip of the wing. Upper disco- 

 cellular vein obliquely longitudinal, very short : middle one much longer, transverse, slightly arched : 

 lower one transverse, rather longer, uniting with the third branch of the median vein at a short distance beyond 

 its origin. 



Hind Wings rather small, irregularly subovate, entire, with long fringes. Costal vein not reaching beyond half 

 tlie length of the costa. Postcostal arising nearer the base of the wing than the precostal (which is small and 

 curved), branching at a considerable distance from its base. Upper disco-cellular vein very slender, almost 

 obsolete, arising at a very short distance beyond the branch of the postcostal, transverse : lower disco-cellular 

 apparently obsolete. 



Fore Legs of the male — ? ; of the female small, slender, and regularly formed, scaly. Tibias shorter rather 

 than the femur or tarsus, the latter regularly articulated. 



Four Hind Legs rather short, scaly; intermediate femora elongated; two posterior tibiae of equal length with the 

 femora, rather swollen ; tarsi of the liind pair of legs considerably elongated. Tibias and tarsi not, or scarcely, 

 armed beneath with fine spines. Ungues and pulvilli minute. 

 Abdomen small, slender. 



This genua is formeil for the reception of two very small species of butterflies, natives of Para, remarkable for the dull and uniform 

 dark colour of the upper surface of the wings, .and the ocellation of the outer margin of the wings on the under side ; the two ocelli, 

 separated by the lower discoidal vein of the fore wings and by the discoidal vein of the hind ones, being united into a large black oval 

 patch, bearing two small white dots. P. Nycteis, represented in our Plate LXXIII., has, moreover, the disc of all the wings beneath 

 dull fulvous buff, marked with a number of minute tranverse streaks ; whilst P. Philotes has them uniform dull fulvous buff. On the 

 whole, the insects bear a certain general resemblance to the small dark-brown species of Polyommatus, whilst the style of the arrange- 

 ment of the ocelli reminds us of Eunogyra and some of the smaller Satyrida;. The junction and subsequent separation of the first 

 branch of the postcostal and the costal veins is especially worthy of notice.
