116 MAJOR E. E. AUSTEN. 



The only obvious differences from British examples of F. hipundata, L., exhibited 

 by the above specimen are that the hair on the scutellum is paler and perhaps longer, 

 that clothing the distal extremity of the abdomen paler, and that covering the wings 

 apparently shorter, while the knobs of the halteres are dead white without a tinge 

 of yellow. 



Family CULICIDAE. 



Of the mosquitos collected and bred by the author during 1917-18, a considerable 

 number were subsequently destroyed by Psocids. The material actually brought 

 home includes representatives of 20 species, all but two of which, however, have 

 already been recorded from various localities in Palestine by Captain P. J. Barraud, 

 in a paper published by him in this Bulletin a few months ago.* It will therefore 

 suffice to mention the additions! to Captain Barraud's list, which both belong to 

 the genus Culex, and are as follows. 



€ulex tritaeniorhynchus, Giles. 



One $, bred, 9.viii.l918, from larva in floating debris : R. Auja, Khirbet Hadrah, 

 6 miles N.-E. of Jaffa. 



€ulex modestus, Fie. 



Two $$, bred, 14,20.v.l918, from larvae in marsh at Tel Abu Zeitun, near 

 Jerisheh, 5 miles N.-E. of Jaffa. 



It may be added that bionomical notes on various species of Anopheles will be 

 found in the author's paper entitled " Anti-Mosquito Measures in Palestine during the 

 Campaigns of 1917-1918,"| although it now appears that in certain cases the 

 nomenclature there used is in need of revision. Thus — 



A maculipennis, Mg., should be A. maculipennis, Mg. var. 

 A. sinensis, Wied., should be A. hyrcanus, Pall. 

 A . palestinensis, Theob., should be A . snperpidus, Grassi. 

 A. turkhudi, Liston, should be A. multicolor, Camb. 



Family SIMULIIDAE. 



Genus Simuiium, Latr. 

 Simulium flavipes, sp. n.

Black ; anterior border of dorsum of thorax with a pale neutral grey patch on each

 or light pinkish cinnamon ; genitalia indistinguishable from those of S. angustitarsis, 

 Lundstr.^ ; legs Naples yellow or pale buff yellow, tarsi, tips of tibiae and of hind 

 femora mummy-brown or sepia-coloured, front tarsi slender, not at all expanded, first 

 joint of hind tarsi strongly incrassate. 



Head : palpi mummy-brown. Thorax : front border of dorsum clothed with 

 minute, appressed, glistening yellowish hairs ; meso- and sternopleurae neutral 

 grey or light neutral grey. Abdomen : hair on abdominal scale pale yellowish. 

 Halteres cream-coloured. Legs : front and middle coxae (at least in some specimens)
