setose tube^ which in that species is coai'sely setose, with 

 both long and slioit, stout, subeiect scire almost to the apex ; 

 also by the dark uniform coloration of the body and the 

 poorly developed wing-retaining and dorsal abdominal spines. 

 The abdomen (excluding tube) is longer and not so stout 

 in gladiatri.v, and the tube tlierefore only about O'G the 

 length of the segments 1-9 together. The surface of Indicus 

 is apparently more strongly reticulated and sculptured than 

 in gladiatrix. 



Tlah. One specimen from the Indian Museum (no. -gir)? 

 Moulmein, Lower Burma, 16. xi. 11 [F. II. Gvave^ij). 



Family Idolothripidse. 

 AcantJitnothrips annidipes, sp. n. 



Length 8 to 9 mm. 



Colour black, shining. Antennal joint 3 greyish-yellow, 

 dark at extreme apex, with yellowish patch just before it ; 

 stem of 4 greyish-black. Distal half of fore-tibise yellow, 

 with black ring just before apex, the intermediate tibiae 

 similar, but with ring near apex broader and not so sharply 

 defined basally ; hind-femora with a yellowish-white ring 

 (in one specimen reddish) at about middle. All tarsi 

 yellowish, dark apically. Wings grey — mid-ribs and cilia

Head about 2"7 times as long as broad near base, cheeks 

 slightly narrowed between eyes and base, and furnished with 

 a few slender setge. Vertex slightly produced beyond eyes. 

 Posterior ocelli on a line drawn through anterior third of 

 eyes, the anterior one near apex o£ produced part. An- 

 tennae extraordinarily slender (excepting the two basal joints), 

 about 3'7 times the length of the head; relative lengths of 

 joints approximately 7 : 6 : 71 : 42 : 33 : 24 : 11 : 9. Post- 

 ocular bristles close together and set rather far back. Eyes 

 finely facetted. 



Pronotum about 0'42 the length of head ; setee weak and 

 colourless. 



All femora thickened distally and furnished with several 

 stout and rather long yellow bristles, somewhat as in Ay^acti- 

 nothrips. Wings reaching to the sixth abdominal segment. 



Abdomen long, segments somewhat as in Actinothrips 

 Tongicornis, apical angles of the hindmost segments, at least, 

 each with a short, stout, yellowish-brown spine, and the ninth
