Mr. R. S. Bagnall on new Thysanoptera. 205 



as long; bristles at posterior angles about one-half as long as 

 the pronotum. Anterior femora very broad viewed Laterally, 

 with the posterior margin strongly arched; fore-tibial teeth 

 prominent, much as in Odontothrips ulicia. Fore-wings 

 moderately slender, pointed at tip, 17 to 18 times as long as 

 wide at middle; setae on costa, upper and lower vein, 26-30, 

 23-26, and 20-23 respectively, snort and slender, but those 

 on costa and lower vein increasing in size towards the tip of 

 wing, where they are more than usually long, being appre- 

 ciably longer than the breadth of the wing. 



Abdomen much as in 0. ulicia, but apical bristles compara- 

 tively shorter and the comb (obsolete medianly in both 

 species) short and sparse. 



J . — The male is much smaller than the female and has 

 tergite 9 postero-medianly produced into two long "arir/s," 

 as long as or overlapping segment 10. 



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



Hob. W. Australia, Perth, Mundaring Weir, Darling 

 Range; several examples of both sexes on flowers of a few 

 prickly herbs with Papilionaceous red flowers, close together, 

 August 3rd, 1914 (E. B. Poulton). Reg. no. '66. 



The species may be distinguished from 0. ulicis, Hal., by 

 its smaller size, the very small interocellar bristles, shorter 

 pronotal and abdominal bristles, etc. The structure of 

 tergite 9 in the <$ is distinctive. 



A[>linothrips rujicornis, var. connaticomis, Uzel. 

 A common species in Europe and North America. 



Hob. Ixdia, Lebong, Darjeeling, Feb. 1909 : 1 ? in tea- 

 lloweis with Pkysothripa lej'royi, Bagn. {Maxwell Lefroy). 



Pseudothrips achaetus, Bagn. 



£ . — I have now secured a good example of this sex, and 

 find that the stemites 3 to 7 have a somewhat strongly trans- 

 verse area on each, that on 3 being the smallest and 7 tho 

 largest. The specialized setre on tergite 6 consist of but one 

 pair somewhat close together, of normal form, slender, and 

 about twice as long as the space between them.
