the head ; ocelli large, placed well forward, the anterior one 
directed forward at the apex of the raised vertex above a line 
drawn across the distal margins of the eyes ; postocular setz 
placed well back, long, being about 1:4 the length of an 
eye. Cheeks sparingly set with minute spines. Mouth-cone 
bluntly rounded, reaching halfway across the prosternum. 
Antenne long and slender, about 1:7 times the length of 
the head, segment 3 very mildly claviform and 4 and 5 
fusiform ; intermediate joints well over twice as long as 
broad; relative lengths of joints 3 to 8 approximately as 
follows :—64: 70: 67 : 57: 50: 382. 
Pronotum about twice as broad as long and half as long 
as the head ; the mid-lateral and postero-marginal sete long 
and well-developed, the inner pair of the latter being longer 
than the outer; the outer of the antero-marginal only 
moderately long, and the inner pair vestigial. Fore-legs 
very strongly developed as in WM. jordani. Wing-margins 
subparalle], not very stout, the fore-wing about 17 times 
as long as broad, and with a series of only two or three 
duplicated cilia. Abdomen elongate-ovate ; wing-retaining 
spines on segments 2-7. Tube rather slender, 0°7 the 
length of the head, terminal hairs about 0°8 the length and 
the abdominal bristles on 9 about as long as the tube. 
This species (coming near jordani, Zimm.) is readily 
recognized by the slender and distinctively coloured 
antenne, the shape of the head, the slender wing with 
unusually short series of duplicated cilia, and the com- 
paratively slender tube.

This species is undoubtedly referable to the genus 
Mesothrips, and it would seem that Karny’s recently de- 
scribed M. pyctes comes nearest to it, if it is not the same 
species.
