twice tlie lenotli of the ninth segment, not three times as 

 long- as broad at base, and twice as broad at base as at apex. 



Hah. British Guiana, Bartica ; 1 ^ collected by 

 Mr. G. E. Bodkin, with Dicoiolhrips brevicornis, Bagn., and 

 D. IcBvkollis, Bagn., from the leaves of the mangoe-tree, 

 June 15th, 1913. 



The unique example is, unfortunately, imperfect, and has 

 been cleared in caustic potash and mounted in balsam. It is 

 only the second described species of Anactinothrips, and is 

 readily separated from A. meinerti, Bagn., by the short and 

 relatively broad head and tube, the relative lengths of the 

 antennal joints, and the short dorsal cephalic bristles as 

 compared to the postociilar pair. The second joint of the 

 maxillary palpi is only tivice the length of tlie basal in 

 A. meinerti. 



Phoxothrips breviceps, sp. n. 



5 . — Length 2'7 mm. Form linear. 



Dark chestnut-brown, head and abdomen almost black. 

 Fore-tibiae and all tarsi yellow. Third antennal joint yellow, 

 shaded brown basally and distally ; basal half of 4 and base 

 of 5 yellow. Head only 2*25 times as long as broad at 

 widest, namely at about the posterior fifth, where it is as 

 wide as across eyes. Produced vertex with sides parallel ; 

 0'25 the total length of head. Eyes laterally occupying 

 about 0*23 the total length of head. 



Antennae at least 1-25 times the length of the head ; 

 relative lengths of joints : — 3 :5:ll:9:7:6:'l: 4 — 3 to 

 5 clavate as in P. pugilator. 



Prothorax about 0*35 the length of head, and 1*4 times as 

 broad as long ; broadest through middle, wdiere it is 1*25 

 times as broad as the head. A somewhat slender seta afc 

 each hind angle. 



Pterothorax 1*25 times as wide as the prothorax, longer 

 than broad. Legs somewhat long, especially the hind pair j 

 fore-femora not incrassate (or armed) in the ? , and tarsus 

 without tooth. Wiup-s reaching; to segment 7. 



Abdomen not broader than the pterothorax, narrowing 

 from segment 7 to base of tube. Tube about 0*6 the length 

 ot head, and twice as broad at base as at a]')ex ; terminal 

 hairs not quite as long as the tube. Abdominal haiis slender 

 and colourless, those on ninth segment longer than tube.
