and’ stretching wholly across the prosteraum. Postocular 
setz situated well towards mid-line, fine and about 0°8 as 
long as an eye. Antenne about twice as long as the head, 
with the relative lengths of joints 3 to 8 approximately as 
follows :—47 : 46 : 41 : 38: 33: 22. 
Pronotum long, about 0°7 as long as the head and 1°5 
times as broad as long. All setz present, well-developed, 
brown, and slightly infundibuliform ; the postero-marginal 
the longest, the outer being 0°5, the mid-lateral about 0°32, 
and those on anterior margin (the two pairs being subequal 
in Jength) about 0°27 the median length of the pronotum. 
Pterothorax stout, wings long and slender, about 20 times 
as long as broad, with 6 duplicated cilia in the fore-wing 
(teste 3). 
Abdomen as in fumipennis, with bristles similarly disposed. 
Tube short and stout, 0°6 as long as the head, less than twice 
as long as broad at base; terminal hairs weak, colourless 
distally and about as long as the tube. Abdominal bristles 
on segment 9 longer than the tube. 
¢.—As in ?, but very slender and slightly shorter; 
although the head is approximately the same in length, it is 
narrower and therefore 1°6 times as long as broad. 
Recognized by the distinctive colouring of the legs and 
the long head.

Cenurothrips affinis, sp. 1. 
Length about 2°2 mm 
Near C. brevicollis, Bagn. Head and thorax dark chest- 
nut-brown, abdomen darker; fore-femora yellow-brown, 
dark brown in the outer half, hind and intermediate tibize 
lighter yellowish- brown in the inner or inner distal parts ; 
hind and intermediate tibie of a uniform dark brown. 
Antenne with first and second joints brown, the latter 
lighter basally; 3 a lighter brown, narrowly yellow at 
extreme base, 4 black-brown, and 5 to 8 still darker, black. 
Wings lightly fumate. 
The head and tube of the unique specimen are split under 
the pressure of mounting, and it is therefore difficult to 
form a correct idea of the shape. : 
Head about as broad as long, rounded in front and 
apparently converging posteriorly as in brevicollis. Eyes
