ries with the costal vein extending to second third of costa ; 

 discoidal cell extremely short, not extending to the middle of 

 wing ; subcostal four-branched, all the branches emitted at 

 some distance beyond the cell, the last, moreover, from below 

 the main vein ; both radials emitted close together from the 

 upper extremity of the cell ; discocellular inarched, second 

 and third branches emitted near together. Secondaries much 

 elongated and sublobate in the middle of outer margin be- 

 tween second and third median branches ; cell very short, as 

 in primaries; costal and subcostal veins emitted from a curved 

 basal pedicle ; subcostal emitting its two branches from a 

 short footstalk just beyond the cell, radial emitted from the 

 superior extremity of the cell ; discocellular slightly inarched , 

 second and third median branches emitted close together from 

 the inferior extremity of the cell. Type X. trucidata. 



39. Xanthodura trucidata, sp. n. 



Orange ; primaries - with the apical third, including the 

 external border, chocolate-brown, its inner margin, termi- 

 nating in a patch at external angle, dark blood-red : secon- 

 daries with a blood-red apical patch ; fringe at apex dark 

 brown; head and collar ferruginous, with white borders; 

 antennas black. Wings below orange ; primaries with the 

 apical third chocolate-brown ; secondaries with a chocolate- 

 brown apical patch : body below cream-coloured. Expanse 

 of wings 1 inch. 



Lechriolepis, gen. nov. 



? . Aspect of Chcerotriche, but the antennas serrate instead 

 of pectinate, the anal tuft enormously developed, consi- 

 derably more so even than in Anaphe; neuration entirely 

 different. Primaries with the subcostal area partially bare in 

 the middle, the scales upon it being placed edgeways and 

 transversely ; these scales are very thick, corneous, and 

 curved, some of them being considerably more elongated 

 than the others, and all of them being fringed or finely 

 serrate at the distal extremity ; costal vein nearly extending 

 to apex ; subcostal six-branched, the first four branches 

 being emitted before the end of the cell, the second and 

 third from a long footstalk, the fifth and sixth branches from 

 a short footstalk at the superior angle of the cell, the sixth 

 branch representing the upper radial; discocellular extremely 

 fine, very oblique, and distinctly angulated ; median vein 

 four-branched, the fourth branch being in reality the lower 

 radial, but emitted with the third median from a short 

 footstalk. Secondaries rather small for the family, and
