plate giving rise to a long tail-like hook directed ventrally. Claspette absent. 

 Basistyle (Bs) about twice as long as broad, outer margin strongly curved, 

 apex narrow; vestiture of scales and numerous setae. Subapical lobe (S-L) deep- 

 ly divided into two distinct trunks: Posterior trunk bearing a long flattened 

 pointed strongly recurved spine, a large broadly expanded leaf-like filament, a 

 narrow leaf -like filament, and two blunt slightly flattened rods; anterior trunk 

 cleaft nearly to base into two stout branches, each bearing a long strong rod 

 with tip flattened, curved and pointed (often with a small apical retrorse barb). 

 Dististyle (Ds) about two-thirds as long as basistyle, curved, narrowed a little 

 before middle, becoming broader at apical third (a row of very short, reflexed 

 setae on outer margin near tip) , tapered to a pointed slightly reflexed apex; 

 terminal claw (Ds-C) short, curved, blunt. 



LARVA. (Fig. 147). — Head much broader than long. Antenna about as 

 long as head, constricted beyond the antennal tuft, with portion before con- 

 striction spinose, portion beyond constriction darker and more sparsely spined; 

 antennal tuft large, multiple, barbed, inserted at outer third, reaching consider- 

 ably beyond tip of antenna. Head hairs: Preantennal (A) multiple, barbed, 

 extending to antennal tuft; lower (B) single, barbed, reaching beyond precly- 

 peus; upper (C) short, weak, 4 or more branched; postclypeal (d) small,
