Mr. R. S. BagiKill on neio Tlojsanoptera. 379 



sparsely setose ; tcnniiial liairs short, yellowisli. Abtlominal 

 hairs moderately short, weak, aiul colourless. 



A very distinct species. 



Ilah, Mataiirr, Sarawak; 1 on dead bark, 1000 ft, 



13. xii. 13; 2 on the wiii^^, 2U00 It., 24. xii. 13 ; 1 ISungei 

 (Jliina, Fort of Mataiig, Sarawak, by beating doad leaves, 



14. xii. 13 {G. E. Bryant). 



Anactinothrlps dislinguendus, sp. n. 



^. — Length 7"5 mm. 



Colour chestnut-brown, lube darker near base and yellowisli 

 distally. Antennse with second joint j'ellowish distally, o 

 with stem yellowish, lightly shaded with brown about 

 middle and apex brown ; 4 with stem y(dlowish, shaded 

 near middle, and 5 lighter basally. Wings greyish-yellow, 

 cilia tinged with brown. 



Head twice as long as prothorax and twice as long as 

 broad near base, shaped as in A.nieinerli, Bagn., but shorter 

 and broader. The pair of dorsal bristles set at about the 

 ba-^al third, only one-half the length of the pnstocular bristles, 

 weak ; anteoeular pair short, pointed, reaching to beyond the 

 middle of the first antennal joint. Eyes tinely tacetted, 

 occupying laterally about 0*22 the total length of the head. 

 Ocelli moderately large, equidistant, the posterior pair close 

 to inner margins of eyes and on a line through their middle. 



Antennaj almost as in A. meinerii, but with the fifth j(niit 

 about four-tifths the len^•th of the fourth (insttad of one-half 

 the length in A. vieineiti) ; approximate lengths of joints: — 

 14 : 12 : 84 : 50 : 40 : 22 : 15 : 12. Sense-cones very short; 

 and slender, scarcely distinguishable. 



Prothorax as in A. meinerti, the postero- marginal bristles 

 broken off in the single preparation, but presumably long; 

 pair at anterior angles short and curved, and the mid-lateral 

 pair long and strong, about 0"G5 the median length of pro- 

 notum. j\Ja.\illary palpi with the second joint three times as 

 long as the basal. 



Pterothorax 0'4 broader than the prothorax, transverse. 

 Wings and legs much as in A. meinerti. 



Abdomen evenly narrowing to tube, with each of tl.o 

 segments 3 to 7 slightly and roundly produced into a promi- 

 nence for the seating of bristles, which latter are evidently 

 (from the tew that aie preserved) not particularly long or 

 strong. 



Tube about 08 the length of the head, a little more than 



20'^
