74 A Monograph of Culicidae. 
Obserrations.— Very close to Grassi’s A. superpictus, but differs 
in the unbanded legs, spotted wing fringe and uniserrated large 
fore ungues in the ¢@, also like Hispaniola, but can at once be told 
by the narrow flat scales on the thorax, of quite a different. 
structure to the narrow hair-like ones in Hispaniola and Turkhudi, 
and clearly relegating it to the genus Pyretophorus. On the 
other hand, it is closely related to P. Chaudoyei, but differs from 
it in the form of the large costal spot, in the apical half of the 
sixth long vein being dark, and in the presence of a deep brown 
median thoracic line. 
Dr. Cropper found the larvae of this species in abundance at. 
Beyrouth, in a runnel of water containing Spirogyra, near the 
Beyrouth River, though the latter was free from larvae. At 
Sidon they occurred and were found in a narrow valley at Ain 
ed Dilb in the chalk. The imagines were caught on rocks at 
the edge of the stream at sunset. Six weeks later, Dr. Cropper 
found them still more abundant, together with Culex mimeiicus. 
They were also found in semi-stagnant pools in the rocky river- 
bed at Banias, and the imagines in tents. Miss Bate informs 
me this species is found everywhere in the plains in Cyprus and 
up to 4,000 feet at Phini.

Synonymy —Without the least hesitation, I feel sure the 
species described by Dénitz is only costalis. This species is very 
marked, and can at once be told; how Dénitz overlooked it I
