XIII. THYSANOPTERA. 



By Richard S. Bagnall, F.L.S., Hope Department of 

 Zoology, University Mtiseiim, Oxford. 



No doubt specialized collecting in more propitious season and 

 circumstances would have produced numerous species of Thy- 

 sanoptera. Only one species was collected, however, namely : 



Sub-order TUBULIFERA. 



Fam. ECACANTHOTHRIPIDAE, Bagnall. 



Genus Ecacanthothrips, Bagnall. 



E. sanguineus, Bagnall.

ser. 8, i, p. 361, 1908 (Apl.).

 Ormothrips sanguineus^ Buffa, Redia, v, fasc. 2, p. 166,

Originally described from a single dried specimen collected by 

 Dr. A. R. Wallace in New Guinea, it has since been recorded b}" 

 Buffa from Sumatra, and the islands Mantawi (Mentawei) and 

 Kngano, and Dr. Karl Jordan has sent me it in large numbers from 

 the Island of Nias. More recently Mr. E. Green has met with it in 

 Cejdon. 



It is a bizarre form, chiefly characterized by the congregation 

 of finger-like sense-cones on the enlarged third antennal joint. 



I cf and I 2 taken under bark by Mr. Stanley Kemp below 

 Dosing (1400 ft.), January 29, 1912 (-li-). Its occurrence in 

 Northern India is interesting.
