Perhaps a distinct species. The P. gossypii (typical), 

 collected by Townsend in 1898 (as reported in Biol. Centr.- 

 Amer.), were preyed upon by Syrphid larvas. The fly has 

 been bred from these, and is kindly identified by Mr. I). W.

Solenophora zapotlana^ sp. n. 



? . — On bark of twigs; broadly oval, about 2^ millim. 

 long, with a slightly produced perforated caudal process, 

 directed a little upwards. Colour a sort of pale ferruginous, 

 but nearly covered with a greyisii-white incrustation. 

 Younger specimens are coarsely cancellated and have irre- 

 gular, long, tongue-hke, lateral processes. $ (adult) boiled 

 m KHO stains the liquid yellowish brown ; the insect contains 

 a dull red pigment. $ a broadly pyriform bag ; antennae 

 mere tubercles, consisting of a ring-like basal joint and an 

 oblong terminal joint (25-30 fju long), tipped with bristles 

 18 ^l long. Skin with very numerous large figure-of-8 glands, 

 about 18 fi across, some smaller. Diameter of moutli-parts 

 about 108 yu-. Spiracles rather small. Caudal tubercles 

 about 65 ^l long, caudal bristles about 130. The caudal end 

 of the insect is abruptly narrowed, with subparallel sides, for
