large, generally incrassate proximally and forked at the tips. There is one marginal

Female, adult (fig. 27, a) generally broadly pyriform, after maceration m potash ; 

 Avidest in the mid-abdominal region ; segmentation distinct ; cephalic region much 

 narrowed. Rudimentary antennae (fig. 27, h) \\\ih two to three spines, usually three. 

 Stigmata relatively large ; a large compact group of parastigmatic glands present 

 at the anterior pair. Large tubular glands numerous and extending as far as the 

 anterior pair of stigmata. Pygidium wnth five groups of circumgenital glands ; in
