SOME NEW AND LITTLE-KNOWN EXOTIC THYSANOPTERA 525 



The hind and intermediate tibiag are shaded with brown 

 below the knees. 



The antennal sense-cones are short and inconspicuous ; 

 there appear to be two on each of the joints four to six, but 

 only a single cone on the third joint on the outer side. The 

 head is only a little more than two and one-half times the 

 length of prothorax, and more than one-half the length of the 

 tube, which, in the type specimen, is extended from the ninth 

 segment and set laterally, thus appearing longer and more 

 slender than it actually is when viewed dorsally. There are 

 no prominent bristles on the fore-coxas, the pair at the 

 posterior prothoracic angles having been mistaken for such. 

 Thus the prothorax has the bristles at the posterior angles 

 moderately long, and in addition there is a smaller bristle at 

 each mid-lateral angle. 



The species was originally described from Siam, and we are 

 now able to record it from Semerang, Java, specimens of both 

 sexes having been taken by Mr. Edv. Jacobson from the 

 young top leaves of the Waringin tree. Two other species 

 ( Phloeothj'ips longihthus sp. n. and P. similis sp. n.) were taken 

 by Mr. Jacobson from the same tree, both closely resembling 

 P. gracilis as regards the type of coloration. 



We are glad to add that we have recently had the pleasure 

 of describing a second species of Panurothrips (P. cmidatus 

 Bagnall) from South Africa.
