288 Mr. R. 8. Bagnall on Thysanoptera 
the outer margin, and the tibiz almost entirely brown. 
Wings fumate, basally somewhat darker. First antennal 
joint light brown; 2 and 38 yellow, the latter lightly tinged 
with grey-brown distally ; 4 yellow, brown in distal two- 
thirds ; 5 to 8 dark brown, with the base of 5 lighter. 
Head as in 6revicollis, but shorter, being about 0°8 as 
long as broad; postocular spines longer than the length of 
the eye, strong; interocular (or interocellar) spines about 
0°6 the length of the postocular, also strong. Ocelli appa- 
rently much as in brevicollis, but difficult to make out in the 
single preparation. Antenne about 24 times as long as the 
head, with apical and penultimate joints closely united ; 
joints 8 and 4 clavate, 5 and 6 with short constricted stem ; 
relative lengths of joints 2 to 8 approximately as follows :— 
40:50: 44:42:40: 26: 23. 
Pronotum transverse, about 0°6 the length of the head and 
about 2°4 times as broad as long. Setz short except the 
postero-marginal ones, the outer pair of which appear to be 
about 0°4 the median length of the pronotum. Fore-wings 
with seven duplicated cilia. Fore-femora incrassate and fore- 
tarsi apparently unarmed; other legs stout. 
Abdomen elongate-ovate, much broader than the ptero- 
thorax. Tube of normal form, about 0°8 as long as the head 
und 1°6 times as long as broad at base. Sides gradually 
narrowing to apical fifth, and then more noticeably con- 
stricted. Abdominal bristles of segments 7 to 9 stout, those 
on 9 apparently about as long as the tube; 6 without any, 
and those on 7 and 8 of approximately the same length and 
noticeably shorter than 9. 
Near C. brevicollis, m., but readily separated by the 
smaller size, the coloration of antenne, the longer and 
narrower pronotum and the smaller and more slender tube, 
the much shorter lateral abdominal bristles on segment 9, 
and the apparent lack of same on segment 6. 
Loc. Roprieurs: 1 @ only. 
3. Liothrips thomasseti, sp. n.* 
Length c. 4°0 mm. 
Colour black, shining; fore-tibize and all tarsi brown. 
Antennal joint 5 brownish-black. 
* Named in honour of Mr. H. P. Thomasset, whose careful field- 
work has done much to increase our knowledge of the zoological and 
botanical productions of the islands in the W.-Indian Ocean.
