NEW GENERA AND SPECIES OF THYSANOPTERA 195 



just below each knee and protecting" each tarsus. Pterothoi'ax 

 closely connected with prothorax, as wide as the width across 

 fore-coxae. Wings long, reaching to the ninth abdominal 

 segment ; coriaceous, with long brownish cilia, irridescent and 

 of a hyaline appearance ; top pair with a smoky tinge towards 

 base. Abdomen apparently no broader than pterothorax ; 

 parallel to sixth segment, and from thence narrowing to base 

 of tube. Tube about one-third longer than head, two and a 

 half times broader at base than at apex; very gradually 

 narrowed to apical third, and from thence rapidly converging 

 to apex ; terminal hairs weak and only about three-eighths the 

 length of tube. Abdominal hairs or bristles extremely long, 

 especially the lateral ones ; those at apex of ninth segment the 

 longest, longer than tube. 



Type — In British Museum. 



Hab. — Santarem. There are three towns of that name, 

 one each in the States of Para and Bahia, Brazil, and the 

 third in Portugal. This species is presumably Brazilian.
