200 NEW GENERA AND SPECIES OF THYSANOPTERA 



Head small, slightly rounded in front ; transversely striate, 

 reticulate near base ; only a little more than one-half the 

 length and slightly more than one-third the breadth of pro- 

 thorax, and only one-ninth longer than broad. Cheeks more 

 or less parallel. Eyes moderate, finely faceted ; post-ocular 

 spines not conspicuous ; inner margin of eyes parallel, and 

 space between them one-third wider than width of eye. Ocelli 

 moderately large, set well forward and widely separated ; 

 posterior pair near margins of eyes, and the anterior one at 

 the extreme vertex of head. Antennce inserted below vertex ; 

 testaceous yellow, basal joint fuscus ; twice the length of head 

 and rather stout. Third and fourth joints broadly claviform ; 

 joints five to seven each similar in shape, length and breadth ; 

 apical joint narrower, and two-thirds the length of penultimates 

 Mottth-cone much longer than the breadth at base, long and 

 pointed, but not reaching beyond the middle of prosternum ; 

 labial palpi long; maxillary palpi also long, with two of the 

 sensory filaments longer than the apical joint. 



Prothoi'ax convex but somewhat depressed, very large and 

 expanded ; narrowed rapidly to apex from posterior third, and 

 upper surface narrowed to base from the same point. Spines 

 at posterior angles long ; those above lateral angles at posterior 

 third not so long; posterior-marginal spines and those at 

 anterior angles small ; anterior-marginal spines apparently 

 obsolete. Fore-coxa large with one long lateral spine ; fore- 

 femur very broad, at least as broad as head. Each fore-tibia 

 broadened and depressed, furnished with several long bristles 

 on the inner margin, one near apex being exceptionally long. 

 Tarsal tooth acute, broad at base and extremely long. Ptero- 

 thorax very slightly narrower than prothorax ; metathorax 

 narrowing posteriorly. Intermediate and posterior legs rather 

 long, with the femora slightly thickened. Wings reaching to 

 seventh abdominal segment, rather slender ; of a testaceous 

 colour, and with long smoke-tinged cilia. 



Ahdomen as wide as pterothorax, narrowly rounded from 

 seventh segment to tube. Tube about one-eighth longer than 

 head, twice the breadth of apex at base, and with the surface
