320 Mr. R. S. Bagnall on new Thysayioptera. 



cylindrical, divided dorsallj, about 0'7 the length of head and 

 0*5 the lengtii of segment 9. Bristles on 9 only about 07 

 the length of 10 ; a stoutish bristle on each side of the longi- 

 tudinal division of segment 10 near apex, 0'8 the length of 

 the segment.

 minal segments dark greyish-brown ; legs dirty greyish-

Type. British Museum of Natural History. 



I]ah. Ceylon, Peradoniya, on leaves of Allamanda, 

 20. 2. U, A. Ruiherford (A. R. no. 3673, Ent. Res. Comm. 

 no. 61), also 27. 3. 14 (no. 83). 



This species differs from the type of the genus, D. hooheri, 

 Hood, in the explanate lateral margins of head, the broader 

 and complete wing-like lateral explanations of prothorax, 

 the series of pronotal setse, and the abnormally strong spines 

 of the fore-wing, which in hookeri are few and inconspicuous. 

 The forms and lengths of abdominal segments 9 and 10 in the 

 two species also differ markedly.

A comparison between Rhipiphorothrips pulchellus, Morgan, 

 from Banyan, Philippine Islands, and my R. hicolor trom 

 Vine, Ceylon, described within a few days of each other, will 

 be interesting. If not one and the same species, they are at 

 least very closely related.
