c^". The male is sharply distingiiished by a single stout sickle-shaped spine 

 protecting each "clasper." The basal anteuual joints 1 and 2 are light, 1 being 

 lightly tinged with brown whilst abdominal segments 2 to 4 are whitish, and 

 the first pair of legs and all femora are very light in colour, yellowish tinged 

 with yellowish brown. 



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



Hah. Occurs gregariously in the flowers of JErica tettalix ; I have 

 i-ecords from Haydon Bridge, Corbridge, and Harbottle in Nortllumber- 

 hmd ; llavenscar, Yorks ; Grange-over-Sands, Lancashire ; Ilfracombe 

 district and Torqua}^ Devon ; New Forest, Hants ; Isle of Wight ; and 

 the Clyde and Forth areas of Scotland. The larva is carnivorous. 

 Outside Great Britain I possess examples from Sardinia (1 S only), 

 Italy, and Spain. 



Aeolothrips alhicinctus Hal. is well known, while the beautiful 

 A. gloriosus Bagn, is as yet only known from Sardinia. 



b. Antennal joint 3 whitish ; bars of wings connected at the hind-margins. 



Aeolothrips conjunctus Priesner. 



I think that it will be found that this is a true species ; Priesner 

 describes it as a variety of fasciatus. It differs from vielaleucus Hal. 

 (nee Uzel) in the much broader and longer white median area and 

 narrow coiuiecting dark margin of the fore wing as shown in Priesner's 

 figure. 



Aeolothrips melaleucus Hal. (nee Uzel). 



This species comes near to fasciatus. The third antennal joint is wholly 

 whitif^h and the fourth is yellowish basally; the whole of the fore-wing is 

 dark brown except the base and apex and a median patch on the fore margin 

 occupying about one-sixth the length and extending in depth to about the hind- 

 vein. Haliday's original description may be translated as follows : " Black ; 

 base of fore-wing, a spot on mid costa and the apex white; third joint of 

 antennae elongated, white." 



This describes the species before me, whereas the one Uzel referred 

 to melaleuca has both the 3rd and 4th antennal joints whitish. 



I have only seen 2 J § taken at Besselsleigh, Berks, on hazel 

 (^ori/his), UM.ldU. 



c. Antennal joints 3 and 4 yellowish white. 



The following three species have the whole of the fore-wing brown 

 or grey-brown except the base and aj)ex : — 



Aeolothrips tiliae Bagn., A. versicolor Uzel, A. tibialis Iveut. 



The species recorded by Schille as versicolor is referable to tiliae.
