358 Mr. R. 8. Bagnall on new ‘Thysanoptera. 
Dolichothrips jeannelt, sp. n. 
? .—Length 3°5 to 3°38 mm. 
Brown to black-brown ; antennal joints 1, 7, and 8 
wholly brown, 2 yellowish distally, 3 yellow, 4 to 6 deeper 
yellow, 5 being lightly, and 6 more strongly, shaded with 
brown distally. 
Head widest across the prominently rounded eyes, about 
1-8 times as long as broad; vertex produced in the form of 
a hump with the anterior ocellus, forwardly directed, at 
apex overhanging insertion of the antennz. Cheeks set 
with a very few minute set, subparallel from just behind 
eyes to the basal fifth or thereabouts and then sharply con- 
verging ; postocular bristies well-developed ; mouth-cone 
very long. Antenne about 1°8 times as long as the head ; 
relative lengths of joits 3 to 8 approximately as follows :— 
Ay 7 oO tev 2 eo 8 de. 
Pronotum long, about 0°7 the length of the head and 
only about 1:2 times as broad near base as long. Pronotal 
sete developed, the outer postero-marginal pair about 0°4 
the median length of the pronotum. Legs long, slender, 
fore-tarsi unarmed, of Liothrips-type. - 
Wings clear and slender, reaching to the seventh 
abdominal segment, without the duplicated series of cilia 
in the fore-wings. 
Abdomen long, gradually narrowing posteriorly; tube 
about 0°6 the length of the head, 2°5 times as long as broad 
at base, where it is about twice as broad as at apex ; terminal « 
hairs very weak distally, brownish basally and 0-7 the length 
of the tube. Abdominal setz well-developed from the first 
segment, the longest on 9 about 0°8 the length of the tube. 
Separated at once from D. longicollis, Karny, by its larger 
size, the shape of the head, the elongated intermediate 
antennal joints, the absence of the duplicated sete in the 
fore-wings, etc., etc. I hope to figure and describe the 
species more minutely when dealing with Messrs. Alluaud 
and Jeannel’s East African material.

A third example is teneral and the head apparently 
deformed in mounting. It is almost certainly referable to
