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 ulicis. Fore-wings 

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

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

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

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

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

 ciably longer than the breadth of the wing. 



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

 tively shorter and the comb (obsolete medianly in both 

 species) short and sparse. 



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

 fcergite 9 postero-medianly produced into two long "arms/' 

 as long as or overlapping segment 10. 



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



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

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

 prickly herbs with Papilionaceous- red flowers, close together, 

 August 3rd, 1914 {E. D. Poulton). Keg. no. 38. 



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

 its smaller size, the very small interocellar bristles, shorter 

 pionotal and abdominal bristles, etc. The structure of 

 tergite 9 in the <$ is distinctive. 



Aptinothrips rujicomis, var. connaticornis, Uzel. 

 A common species in Europe and North America. 



Hob. India, Lebong, Darjeeling, Feb. 1909 : 1 ¥ in tea- 

 flowers with Pkysothrips lefroyi, Bagn. {Maxwell Lefroy). 



Pseudothrips achaetus, Bagn. 



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

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

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

 largest. The specialized setae on tergite 8 consist of but one 

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

 about twice as long as the space betweou them.
