Mr. R. S. Bagnall on new ThysanopU • rt. 2G3 



being as follows :— 42 : 37 : 26 : 37 : 6 : 11. Colour of an- 

 tenna3 entirely brown except for joint 3, which is of a clear 

 light yellow. Fore-wings (excepting for a small area on the 

 lower margin) without the clear basal space seen in both 

 iilirls and uzeli. Fore-tibia with one " tooth " reduced to a 

 very small sharp tooth and the other replaced by a dark 

 stout seta. 



Readily recognized by the armature of the fore-tibia?, the 

 obfuscate base of fore-wings, and the colour of the antennas, 

 &c. 



Type. In Coll. Bagnall, University Museum, Oxford. 



Hab. SPAIN, Ortigosa (Logrosa), 1892; ? $ only (Coll. 

 Navas). 



Genus Fkankliniella, Karny. 



a. Small yellow species. 



Franhliniella dek'catula, sp. n. 



? . — Length c. 1*0 mm. 



This species resembles F. pallida (Uzel) somewhat 

 closely, and may be separated by the more slender antenna?, 

 which has a much longer style, the apical joint being much 

 longer than the basal. The pionotal macrochsetse are shorter 

 than in pallida. The fore-wings are colourless and have 

 noticeably fewer spines, whilst the series of spines on the 

 inner margin of hind tibia are also fewer in number. 



The species will be more closely described in a paper I 

 hope to prepare shortly on Messrs. Alluaud and Jeaunel's 

 material from East Africa. 



Hab. East Africa, 1 $, 1. i. 1912; Kikuyu Country, 

 Blue Post Hotel, situated at the confluence of the rivers 

 Thika and Tchania, about 50 kilometres from Nairobi, alt. 

 1520 metres (Alluaud et Jeannel, no. 29). 



? Frankliniella cephalica, Crawf. 



The species I recorded from Trinidad as F. melanommata, 

 Williams, is not truly referable to that species. I believe 

 that it is referable to cephaliGa, but unfortunately the anal 

 segments of the male of neither species is described satis- 

 factorily, no mention being made of the specialized dorsal 

 spines of the ninth tergite.
