terior to the subquadrangle in the hind wing. Quadrangle, sub- 

 quadrangle, and wing petiolation essentially as in Archilestes, 

 from which it is separated at once by the retracted nodus (wing 

 base to nodus less than one-third the wing length in Cyptolestes, 

 more than one-third in Archilestes); by the more distal forking 

 of Mi+2 and Mj (distance from arculus to forking about equaUing 

 the length of the second antenodal costal space in Cyptolestes, 

 much shorter in Archilestes); by the greater length of the first 

 postquadrangular cell (anterior side longer than proximal side 

 and posterior side longer than distal side in Cyptolestes; anterior 

 and proximal sides about equal, and posterior and distal sides 

 about equal in Archilestes); by Mj ending at the wing margin 

 proximal to the level of the stigma (under the stigma in Archilestes) ; 

 and by the greatly shortened stigma. Other venational characters 

 of Cyptolestes are: bridge vein of Rg meeting M1+2 adjacent to 

 Mj or in the fork, or, in one front wing of a female, arising from M3 

 near the fork; M2 arising at slightly before the second postnodal 

 to three-fourths the distance between the second and third post- 

 nodals beyond the second in the front wing, and at three-fourths 

 the distance between the first and second postnodals beyond the 

 first postnodal to two-thirds the distance between the second and 

 third postnodals beyond the second postnodal in the hind wing; 

 Mja straightened, not zigzag, arising just before the sixth to the 

 eighth postnodal in the front wing, and just before the sixth to the 

 seventh postnodal in the hind wing; two short sectors between 

 Mja and M2, two between M2 and Rs, two between Rg and Mj, 

 and only one distinct one between M3 and M4, this one parallel 

 to M4; a more or less distinct sector between this one and Mj 

 (in Archilestes there are at least three more or less distinct sectors 

 between Mj and the short sector parallel to MJ; Cuj and Cu, 

 arising from the medio-anal hnk almost at a point; postnodals 

 front wing 17-19, hind wing 16-18; stigma covering two to three 

 and one-half cells, two and one-half to three usually. In the
