NATURAL HISTORY. Ixv 



minent, as well as two ocelli ; wings pale ochreous fuscous, pubescent and glossy, 

 superior elongated and narrow, gradually narrowed to tlie base ; cilia short ; inferior 

 wings iridiscent ; tibiae and tarsi dull ochreous, with numerous short black bristles 

 inside, and especially beneath the latter; the four posterior tibiaa furnished with 

 ochreous spurs at the apex. 



This insect has the habit of a Tinodes, but the neuration of the wings does not 

 quite agree with any in my possession, and it has but one pair of spurs to the posterior 

 tibiae; if, therefore, the antennae were not wanting, I should be disposed to give it 

 a generic name.

 abdomen black, clothed with long whitish hairs, rosy on the collar and head ; wings 

 sulphur colour, freckled with black at the base, and at the posterior margins forming a 

 dentated fimbria, which vanishes before reaching the anal angle ; costa and cilia rosy, 

 the nervures sometimes rather dark in the superior wings, with a large space of orange 

 not approaching the costa or posterior margin ; at the apex of the discoidal cell is 

 a black sublunulate spot ; inferior wings with a ferge orange spot on the disc, and 

 sometimes a small one above it ; underside thickly freckled with black, especially the 

 inferior wings, but less so at the posterior margins; the entire edges of the wings are
