white; frons fulvous; antennse seven-jointed, basai joint conical, 

 the second to fourth obconical, fifth to seventh fusiform ; the termi- 

 nal joint terrainating in an acute point; head rounded, truncate in 

 front and behind, with a central obtuse carina and an oblique stria 

 behind each eye. — Length 3 mill. Rodriguey, coll. by Gulliver. » 



Belonging to the Tubulifera, and possessing wings and ocelli it 

 is difficult to understand as to why it was referred to the wingless 

 Terebrantian genus Aptinothrips. 



The type spécimen, which I hâve recently had the opportunity 

 of examining, is in the British Muséum of Natural History. It 

 belongs to the genus Anthothrips and is at once distinguished by 

 the oblique channel behind each eye. From the appearance of the 

 abdomen, which is a little lighter than the gênerai colour of the 

 insect, the spécimen would appear to be slightly immature. It has 

 perhaps been killed in alcohol or boiling water and then gummed 

 on to the card; the abdominal segments are distinetly exerted, the 

 space between tbe separated margins of the segments showing 

 white and thus giving, unnaturally, the banded appearance des- 

 cribed by Butler. The name fasciatus is therefore unfortunate. 



çÇ (?). Colour chestnut brown, feet (only one of the intermediate 

 pair visible) yellowish ; Antenna? with joints 1 and 2 dark and 3 to 

 8 light chestnut brown, the bases of 3 to 6 yellowish. 



Head a little longer than broad, cheeks feebly rounded; eyes 

 large, finely facetted and the space between them only equal to two- 

 thirds the breadth of one of them. Ocelli notequidistant, moderately 

 large and space between posterior pair equal to the diameter of 

 one of them, contiguous with the inner margins of eyes; anterior 

 ocellus placed at apex of a slight prominence. Postocular bristles 

 knobbed and about as long as the eye. Surface roughly striate, 

 reticulate near base; a deep well-marked furrow converging 

 inwardly from base of each eye. Antennse less than twice as long 

 as the head, joints 3 to 6 mildly clavate; 3-4 broadest and about 

 equally broad; apical and penultimate joints together only slightly 

 longer than the sixth. 



Prothorax transverse, slightly shorter than head; bristles at 

 posterior angles moderately long, longest; mid-lateral, anterior- 

 marginal and pair at anterior angles practically subequal and 

 about two-thirds the length of the pair at posterior angles ; posterior 

 marginal pair weaker and slightly shorter than thèse at posterior 

 angles. Plerothorax almost square. Wings short, reaching to sixth 

 abdominal segment, iridescent and darkiung towards tip, broad and 

 furnished with moderately short smokey-coloured cilia ; t« o pairs of 

 wing-retaining spines up to the sixth abdominal segment, but 

 vestigial on segment seven. Basai wing-spines apparently knobbed.
