324 Mr. R. S. Bagnall on new Thysanoptera. 



Liothrips micrurus, Bagnall. 

 Ann. & Mag. Nat. Hist. ser. 8, vol. xiii. p. 292 (March 1014). 



This species is apparently attached to Zyziphns sphii-chrisf,', 

 and was described from a speciim^n obtained by Mr. F, 0. 

 AVillcocks at Matarieh, near Cairo. Mr. Willcocks lias 

 found other specimens on the same tree from Ezbet-el-Nakhl, 

 February, and at Gizeli, near Cairo, March 1911. Evidently 

 rare. 



In describing it I stated that a carded specimen captured 

 by Prof. Sahlberg of Helsingfors at Fleluan exhibited a pro- 

 nounced metallic-purplish coloration. 



Mr. Willcocks has furnished me with the following live- 

 colour notes of the species — the first known thrips to exhibit 

 metallic coloration of any kind : — 



Head, thorax, and abdomen deep metallic violet — in some 

 lights appears jet-black ; hairs on abdomen j)nle. Eyes very 

 dark brown. Antennse : two basal joints dark, others pale 

 yellowish-brown. Wings silvery, with pale brownish fringe. 

 Legs deep metallic violet. 



Genus Aleurodothrips, Franklin, 1909. 



Chromatothrips, Schmutz (type C.fasciata, Schmutz), K. Akad. Wiss. 

 Wien., Mathem.-Naturw. Kl. cxxii., July 1913, p. 1043. 



I consider that the type-species of Chromntot.hri2'>s is closely 

 related to Aleuroduthrips fasciatipennis^ Fraidil in, and con- 

 generic with it. 



Aleurodothrips fasciapennis (Franklin). 



Ceylon, Peradeniya, 1 cJ taken by Mr. A. Rutherford 

 among Aspidiotus lalanue, 27. vi. 1913. 



Tlie only difference I can detect in this example and 

 specimens from Florida lies in the coloration of the antennie, 

 the former having the sixth joint entirely grey-brown. 

 A. fasciatiis closely resembles this species, but is easily 

 distinguished by tlie coloration of the body, antennae, and 

 legs.
