354 SATYRTD^. 



the black colour with a clearly defined margin edged with fulvous, and the costa of the hind wings broadly fulvous brown. The 

 opposite sex (D. Agondas) has all the appearance of a large, uniformly coloured, sooty black Satyrus. It might indeed almost be 

 mistaken at first sight for a specimen of our Pronophila Cordillera. On the upper side it is of a sooty black, the apical margins of 

 the wings with an obscure greenish ashy tinge ; the costa, especially towards the apical angle, having a rather more green tinge. On 

 the under side the wings are entirely blackish brown, except a large transverse-oval fulvous patch near the anal angle, bearing a large 

 round and a smaller oval spot, both black, with blue scales in the middle (forming a double pupil in the larger one next the anal angle). 

 The position of the genus is very doubtful, from the peculiar characters of the insects, of which the most remarkable are, the palpi 

 scarcely hirsute iu front, the dilated costal vein of the fore wings in both sexes, the silky patch on the disc of the hind wings of the 

 males, the small prediscoidal cell of the hind wings, as well as the regular ocellation of the under side of the hind wings in the males ; 

 whilst the female has these wings marked much more like those of the genus Drusilla. With such a combination of characters, it 

 cannot exclusively be associated either with the Nyraphalida;, Morphida;, or Satyridas. We have to return our best thanks to Dr. 

 Boisduval for the use of his unique specimens of these two remarkable insects.

" Head of moderate width, liairy. 



]\IaxiUoe about two tliirds the length of the body, I'ather slender. 



Labial Palpi porrect, ascending, longer than the head, clothed with hairs and scales ; the scales at the back of 

 the second joint forming a tuft before the apex. First joint shoi't, subcylindric, curved, stoutest at the base ; 

 second joint three times the length of the first, subcylindric, slightly curved at the base, incrassated towards 

 the apex, which is truncate ; third joint slenderer than the second, about half its length, nearly cylindric, 

 obtuse at the apex. 



Eyes nearly round, not very prominent, smooth. 



Antenna; less than two thirds the length of the body, slender, grooved below, thickening gradually into a slender 

 obtuse club. 

 " Thorax moderately stout. 



Anterior Wings subtriangular. Anterior margin slightly arched. The outer nearly straight, three fifths of the 

 length of the anterior. Inner margin nearly straight, four fifths of the length of the anterior. Costal nervure 

 swollen at its origin, terminating beyond the middle of the anterior margin. Subcostal nervure rather 

 slender ; throwing off its first nervule at a short distance before, its second immediately before, the end of the 

 cell ; the third at a point about as far beyond the end of the cell as the origin of the first is before it ; its 

 fourth about as far bej^ond the third as the origin of this last is distant from the origin of the second; fourth 

 subcostal nervule terminating at the apex of the wing. Upper disco-cellular nervule very short; middle and 

 lower disco-cellular nervules about equal, the former curved inwards, the latter outwards; a rudimentary 

 discoidal nervule extending inwards from the middle disco-cellular nervule. Median nervure swollen at its 

 base ; its third nervule bent at a considerable angle where it is joined by the lower disco-cellular. Submedian 

 nervure stout, curved near the base. Internal nervure wanting. 



Posterior Wings obovate, produced into a short tail at the anal angle. The anterior margin nearly straight ; 

 the outer much curved ; the abdominal fold ample. Precostal nervure stout, curved inwards. Costal nervure 

 rather stout, curved at its origin. Subcostal nervure rather stout, bent at a considerable angle where the 

 costal separates from it ; its second nervule angular, where the straight upper disco-cellular nervule 

 anastomoses with it. Discoidal nervule extending into the cell. Lower disco-cellular nervule straight, longer 

 than the upper, anastomosing with the discoidal nervure a long way beyond the anastomosis of the upi)er 

 disco-cellular. Third median nervule bent at nearly a right angle where the lower disco-cellular anastomoses 

 with it. 



Anterior Legs of' the male slender, thinly clothed with scales and long delicate hairs. The femur rather shorter 

 than the tibia. The tarsus little more than two thii-ds the length of the tibia, one-jointed, nearlv cylindric.
