above anopheles. This egg is the most aberrant tjpe of anopheles egg yet 

 described. 



Habitat and Observations. — This anopheles was found in two springs near 

 D'thala, also on Jehaf, hence its name. It was caught in the Hospital tents at 

 D'thala and was breeding in the wells. In December and January it was found 

 breeding in the spring at Hardeba. Some specimens were caught in the tents at 

 Sulek in January. This anopheles has not been found anywhere else. It is 

 a large anopheles and is easily recognised from the other Arabian varieties by the 

 four palpal bands. 



Some specimens were sent to Mr. Theobald, who suggested it might possibly be 

 A. cinereus, Theobald. A. cinereus has been placed by Mr. Theobald in his new 

 genus Pyretophorus but this anopheles undoubtedly falls in the genus Myzomyia. 

 The wing markings will at once separate it from A. cinereus. I would like to 

 throw out the suggestion that this mosquito is possibly a malaria transmitter in 

 nature. It was caught in tents and was biting freely. This, however, needs 

 further investigation. 



Anopheles (Myzomyia) azkiki n. sp. 

 Palpi, three bands, apex black ; thorax light brown, abdomen brown, legs dark, 

 no bands. 



Female. — Head covered with brown upright forked scales, scattered among 

 these are many brown curved scales. A tuft of light hairs is seen extending 

 over the clypeus on both sides; antennae are dark, clypeus is light. Palpi 

 (Fig. 18) are lightly scaled, with three white bands, apex is black. 



Thorax is brown and covered with brown curved scales and hairs, scutellum 

 is dark, with bristles along its border, metanotum is almost black. 



Abdomen is brown covered with light hairs, there are no scales on the abdomen. 

 Legs are brown with pale spots at the joints. 



Wing. — (Fig. 19) Costa has five black spots and subcostal two. 1st longitudinal 

 has four spots. The 2nd vein has two on its main stem with two on the upper 

 and two on the lower branch. The 3rd has two spots, one near the base the 

 other at the apical end. The 4th vein has two black spots on the main stems, 

 one on the upper and one on the lower branch. The 5th vein has one black 

 spot on the stem, one short and one long on the upper and two long spots on the 

 lower branch. The 6th vein has one long spot extending almost up to the fringe. 

 The fringe is dark with no light areas opposite the terminations of the ocius. 

 Male. — It is much lighter than the female. The palpi often have four pale 

 areas, the apex often being pale. The wing is much lighter than the female, 

 many of the spots are wanting. The legs are brown, fore ungues unequal and 

 uniserrated. 



Larva. — A light green larva with amber coloured head. Frontal hairs are 

 simple and unbranched. 



Palmate hairs are present on 4th to 6th abdominal segments. Each blade is 

 broad and stumpy (Fig. 20) with serrated shoulders and the filament is a mere 

 spike ; the antenna? have a small spine on the outer side.
