LEPIDOPTERA— TINBID^. 603 



PSECADIA MORTUELLA. 



PI. 15, Figs. 12, 17. 



A single specimen has been found with its reverse. The insect is pre- 

 served lying upon its side, and though the neuration can not be seen from 

 the wing having been heavily scaled, the whole of the antennaj and most 

 of the palpi, tongue, and legs are well preserved. The palpi are closely 

 recurved over the head, the middle joint apparently of about the same 

 length as the apical joint, compact but heavily clothed, appressed to the 

 front, reaching the summit of the eye, the apical joint very slender and 

 pointed, directed at last backward, reaching the back of the head Antennae 

 fully two-thirds as long as the wings, slender, naked, gently tapering, the 

 basal joint stout, rounded apically, not over twice as long as broad, the 

 succeeding joints uniformly cylindrical, about twice as long as broad, trans- 

 versely sulcate in the middle, as if made of two subjoints, relatively a little 

 lonarer near the middle of the antennas than at the two extremities, the sec- 

 ond joint three-fourths the diameter of the first and only as long as broad. 

 Tongue at least as long as the middle femora, with no sign of squamation 

 at the base anteriorly. Wings full}' tin-ee times as long as broad, the apex 

 roundly but acutely angulate, all heavily squamate. It is difficult to make 

 out what the markings may have been, but it would appear that the wings 

 were grizzly with an interrupted series of small darker spots along the 

 proximal half of the costa, and another series down the middle of the wing 

 on its distal half The legs are not very long, the fore legs somewhat 

 shorter than the middle pair and much slenderer, the tarsi considerably 

 shorter than the femora, and fully as much longer than the short libia. 

 The middle legs are very much shorter than the hind pair, the tibia and 

 tarsi of equal length and each about three-fourths as long as the broad 

 femur; the tibia armed apically with a pair of excessively long spurs. The 

 hind legs can not be fully determined, but the tarsi are about twice as long 

 as the middle tarsi, and the double series of tibial spurs as long as those of 

 the intermediate tibiae.
