144 THE SCOTTISH NATURALIST 



is, connected with the spread of malaria in Scotland. As a matter 

 of fact three species of the genus Anopheles are known to occur in 

 Scotland, as may he-ascertained by consulting "Studies in Relation 

 to Malaria," by Nuttall and others, in the Journal of Hygiene, vol. i. 

 (1901), and Theobald's Monograph of the Culicidce or Mosquitoes, in 

 the fifth volume of which, published in 1910, records by Dr J. H. 

 Ashworth and myself for Edinburgh and its neighbourhood are 

 given. In Midlothian I have found: (1) the larvae of A. nigripes, 

 (from which the male fly was reared a month later) in a weedy pool 

 near Lasswade on 17th September 1909; and (2) A. biftrcatus at 

 the old marl pit, south of Davidson's Mains, near Edinburgh, where 

 on 29th May 1913, between 6.30 and 7 p.m., the weather being then 

 warm and sultry, both sexes of the adult insect were abundant the 

 males were rising in groups into the air, so that some scores were taken 

 by a few sweeps of the net, while most of the females taken were 

 flying just above the vegetation of the marsh. In Fife, on 2nd July 

 1909, in a wood above the railway between Aberdour and Burnt- 

 island, I found myself a source of interest to a species of mosquito, 

 four specimens of which I secured by holding out my left hand and 

 allowing them to settle on it ; they proved to be females of 

 A. nigripes. So far there appears to be no record of A. maculipennis 

 from the Forth district. It has, however, been recorded from 

 Aberdeenshire. 



The occurrence of another interesting Culicid, namely, Aedes 

 cinereus, Mg., in this district may be mentioned. On 15th July 

 1905, I took about twenty specimens, all females, in a small marsh 

 beside a wood west of Dollar, Clackmannanshire. It was one of 

 these specimens, given by me to Mr Collin, that Mr F. W. Edwards 

 recorded from " Edinburgh " in the Entomologist for September 

 191 2. William Evans, Edinburgh. 



A Correction. In my paper on Aphides in the April number 

 of the Scottish Naturalist, on page 89, the 6th line from the 

 bottom, for "sixth segment" read "fifth segment." The faint 

 pseudo-division of the third joint of the antennae of Pemphigus 

 glebce. has, in the reproduction, been rendered too distinct, making 

 it appear like an additional joint, which is incorrect. D. J. Jackson.
