THE BLOOD-SUCKING DIPTERA OF PALESTINE. IIS 



developed purplish iridescent sheen, and with sharply defined, spot-like, milk-white 

 or cream-coloured markings, chiefly along distal and posterior borders, as shown in 

 figure ; hind border of axillary cell to level of axillary angle, and greater part of 

 distal half of each wing fairly thickly clothed with decumbent hairs, which as usual 

 are especially close together on distal third, particularly in area beyond distal costal 

 spot. Halteres : knobs straw-yellow, stalks cream-coloured. Legs : femora and 

 tibiae light sepia-coloured (hind femora somewhat darker), knees (tips of femora and 

 extreme bases of tibiae) and tips of hind tibiae mummy-brown ; tarsi, extreme bases 

 of all femora, a ring immediately before tips of front and middle femora, and a similar 

 ring immediately beyond bases of all tibiae and before tips of hind tibiae cream- 

 coloured ; hind femora with a faint indication of a narrow pale ring before tips ; 

 hind tibiae with a row of long, dusky hairs on extensor surface, hair on tarsi and on 

 flexor surface of hind tibiae pale.

 on lining, above lighted lamp. 



Ctdicoides odibilis is allied to the foregoing species {Cgnttidaris, Kieff.), from which 

 however it is readily distinguishable by the neutral grey markings on the dorsum 

 of the thorax, by the differences in the (^ hypop3^gium detailed above, and by the 

 much more sharply defined wing-markings, in which the pale spots are considerably 

 less extensive.

The specimen referred to agrees on the whole very well with Kieffer's description 

 of the species, the type of which was obtained in Tunis. The inner margins of the 

 upper lobes of the eyes, though separated above by a space, the width of which is 

 approximately equal to that of the flagellum of the antenna, are closely approximate 

 below. In the much bespotted imngs, practically the entire surface of which is thickly 

 clothed with decumbent hairs, the dark fleck (alluded to by Kieffer) enclosed in the 

 proximal pale costal blotch is situate immediately beyond, and in contact with, the 

 anterior transverse vein, occupying the angle formed by the latter and the praefurcal 

 portion of the fourth longitudinal vein ; a small pale fleck inside the fork of the 

 fourth vein, close to its base, is not mentioned by Kieffer. 



Note. — In an addendum to a short paper by E. Brunetti on " Some Noxious 

 Diptera from Galilee " (Journ. Asiatic Soc. Bengal, New Ser., ix, pp. 43-35, 1913), 

 Dr. N. Annandale writes {loc. cit., p. 45) : — " Another irritating blood-sucker comrnon 

 at Tiberias in October, though much less so than Ph. papatasi, is a minute Chiro- 

 nomid of the sub-family Ceratopogoninae. Like PJdebotomns it is nocturnal in its 

 habits." On p. 370 of Vol. x of the same journal (1914), in a note to Kieffer's 

 description of Trichotanypus tiheriadis, Kieff., Dr. Annandale remarks : — " This is 

 the species I referred to in a note on a former paper (J. A. S. B. (n.s.), ix, p. 45, 1913) 

 as being a troublesome bloodsucker at Tiberias." There would appear to be some 

 confusion here, since the genus Trichotanypus does not belong to the Ceratopo- 

 goninae, and the species included in it are structurally incapable of sucking blood.
