274 Mr. K. S. Bagnall on new Thysanoptera. 



long, about 0'26 the length of the head, fundibuliform. 

 Antennae approximately twice as long as the head, segments 

 3 and 4 subequal, and 5 to 7 slightly shorter and also approxi- 

 mately subequal ; relative lengths of! 3 to 8 as follows : — 36 : 

 35 : 30 : 30 : 30 : 21. 



Pronotum transverse, nearly twice as broad as long ; all 

 seta? present, dilated apically and well-developed ; those at 

 posterior angles longest, about 0*4 the length of pronotum ; 

 the postero-marginal and mid-lateral pairs 0'35 and the antero- 

 marginal pairs 0'3 the length respectively. Fore-femora 

 stout ; fore-tarsi each armed with a short tooth. Fore-wings 

 normal, cilia sparse, few and widely spaced, duplicated cilia 

 in three specimens 5 : 6, 5 : 6 and 5 : 7 respectively. 



Abdomen not as broad as the pterothorax, tube - 75 to 0*8 

 the length of the head, about 0*45 as broad at base as long, 

 and halt' as broad at apex as at base. Apical hairs longer 

 than tube, dark in the basal two-thirds but losing colour and 

 very slender distally. Abdominal bristles light-coloured, the 

 longest on segment 9 about 0*6 the length of tube, and colour- 

 less distally ; those on 7 the same length, but stouter. 



Type. In Coll. Bagnall, University Museum, Oxford.

Haplothrips unicolor, sp. n. 



? •■ — Length 1*5 to 1*6 mm., breadth of mesothorax c. 

 0'3 mm. 



Colour of a uniform deep black-brown including tarsi, fore- 

 tibife yellowish-brown distally ; third antennal joint a little 

 lighter in shade than the others. Wings, excepting scale 

 which is brown, clear. 



Head rather large, divergent posteriorly (though this may 

 have been caused in mounting), and about 1*5 times as long 

 as the pronotum ; ocelli situated well forward on a produced 

 prominence, the anterior ocelli overhanging and well in front 

 of a line drawn across the anterior margins of the eyes. 

 Antennas about 1*5 times as long as the head ; joint 4 

 broader than any of the others ; relative length of segments 

 3 to 8 approximately as follows : — 44 : 47 : 44 : 42 : 38 : 24,
