plate elongate, with a short stout curved tooth at apex and a blunt subapical 

 lateral lobe; base of each plate with a long, tail-like hook directed ventrally. 

 Claspette absent. Basistyle (Bs) very large, nearly spherical, clothed with 

 scales and numerous rather fine setae. (C. peccator may be easily distinguished 

 macroscopically by these greatly swollen basistyles.) Subapical lobe (S-L) 

 deeply divided into two distinct trunks: Posterior trunk with a large greatly 

 expanded leaf-like appendage arising from a stout branch, and three rod-like 

 filaments, each with a lamella apically, arising from smaller branches; anterior 

 trunk bearing an apical rod retrorsely spined at tip, and a lateral rod somewhat 

 flattened and angulate near tip. Dist'istyle (Ds) about half as long as basistyle, 

 constricted at basal third, quadrately expanded beyond constriction, hirsute on 

 crest; a short, curved spine inserted a little before apex. 



LARVA. (Fig. 149). — Head much broader than long. Antenna about as 

 long as head, constricted beyond antennal tuft, with portion before constriction 

 spinose and that beyond constriction darker and more sparsely spined; antennal 

 tuft large, multiple, barbed, inserted at outer third, reaching beyond tip of 

 antenna. Head hairs: Preantennal (A) multiple, barbed, reaching to insertion 

 of antennal tuft; lower (B) single, sparsely barbed, extending beyond precly- 

 peus; upper (C) small, double or triple, occasionally single, less than half as 

 long as lower (B) ; postclypeal (d) small, single; sutural (e) usually double
