S. 83, 84, 1913. 



The town of Tokar, some distance inland from the Red Sea coast, is the 

 centre of a cotton-growing district inundated annually by a flood-river or "Khor". 

 In drying after the inundation the alluvial soil cracks vertically to a depth of 

 several feet, and horizontally. This cultivated area is notorious for the number 

 and bloodthirstiness of its Phlebotomus. They are found as much as two miles 

 from any wall or building, and are equally abundant in well cultivated and weedy 

 places. They seem to be present only in the flooded area, and not to be nume- 

 rous in the town of Tokar, which is raised above the flood-level. As a result of 

 investigations in the Island of Malta it was found that all Phlebotomus larvae dis- 

 covered in that Island were living under similar environmental conditions as re- 

 gards (a) presence of organic matter, (b) presence of moisture, though not in 

 excess, (c) absence of light. The author considered that near Tokar these con- 

 ditions could only be fulfilled in the cracks in the soil, which he consequently 

 investigated as far as limited time would allow. Adult Phhbotumus were found 

 in myriads under the clods of earth, and a Phlebotoinns-lsivva. was actually found 

 at a depth of 4 inches, in damp earth, near one of the vertical cracks. The evi- 

 dence as to these cracks and the soil near them being the main habitat of the 

 larvae is inconclusive, but the author believes that extended investigation will 

 prove this to be the case. H. Scott (Cambridge).
