one example, and are much lighter than the intermediate and 

 hind pairs of legs. The dark and light areas of the fore- 

 wings are roughly subequal in extent. 



The head is as long as the prothorax and has the cheeks 

 more strongly arched. In A. fasciatus the third antennal 

 joint is longer than the fourth, in this species it is the same 

 length (excluding pedicel) or slightly shorter (16 : 16 in one 

 specimen and 15 : 17 in two). 



The small seta? on the longitudinal vein of the fore-wings 

 are fewer, very minute, being 0*5 to 0*3 the length of the 

 corresponding setae in A. fasciatus, lighter-coloured, and 

 therefore more inconspicuous.

$ . — Length c. 1"0 mm. ; form somewhat slender. 



Colour brown, antennae entirely concolorous with head ; 

 legs yellowish-brown to brown ; wings brown, apparently 

 somewhat lighter basally. 



Head transverse, 0'7 as long as broad ; cheeks sub- 

 parallel ; eyes large, occupying about 0'4 the total dorsal 

 length of head ; eyes moderately coarsely facetted and 

 sparingly pilose ; ocelli large, set well back, with crescentic 

 hypodermal pigmentation ; interocellar and postocular seta? 

 minute ; dorsal surface transversely striate. Antennae 

 6-jointed, a little less than twice as long as the head ; third 

 joint (without trichome) very much shorter and narrower 

 than any of the other joints (excluding style), pedicellate; 

 relative lengths of joints approximately 8 : 13 : 7 (excluding 

 pedicel) : 16 : 23 : 3. Stout forked trichome on 4. Mouth- 

 cone reaching across presternum ; maxillary palpi rather 

 long, 3-jointed, the third joint longest * ; labial palpi long, 

 slender. 



Pronotum slightly longer than the head, about 1*6 times 

 as broad as long; posterior margin depressed; bristles at 

 each posterior angle stout, about 0*4 (or slightly less) the 



* Although I have not demonstrated it to my entire satisfaction, I 

 think that the maxillary palp of Ceratothrips britteni, Bagn., is also 

 3-jointed; I described it as "apparently 2-jointed," but the unique 

 preparation is very obscure.
