128 ERNEST HILL AND L. G. HATDON. 



This species lias been found in Natal, from sea level to an 

 elevation of 4000 ft., above which Ave have not made search, 

 and the larvae have been taken, and imagines obtained from 

 them throughout the year. It is the commonest and most 

 widely distributed of Anophelina. 



Two definite varieties are found : a smaller, of which the 

 average measurement of detached wing is 3 mm., a larger 

 of average measurement 3"8 mm. Intermediate sizes are also 

 observed. Dark individuals, corresponding more or less with 

 umbrosa and subumbrosa, are very occasionally en- 

 countered, the larvfe being captured among the ordinary 

 type. Insects of greater and lesser measurement are about 

 equally common on higher grounds, as at Maritzburg, 2200 ft., 

 but in our present collection of some fifty females we have 

 none of the larger variety from coast districts. 



The width of the bands on the palpi vary considerably, and 

 the apical band is rarely as narrow as figured in ' Monograph 

 Culicid^,^ vol. iii, p. 36, and on that account is inadmissible 

 as a specific distinction. 



Theobald's description of the wing does not tally with his 

 diagram on page 36, in which a lengthening of the second 

 yellow spot on the first long vein is shown, which is not men- 

 tioned in the text. In the species as found in Natal, this 

 feature is always present, generally as shown on Plate XXV, 

 fig. A, less frequently as a distinct spot, separated by a few 

 or several, black scales from the spot beneath that on the 

 costa. The figure is representative of the markings of both 

 varieties, but considerable variation is found, as shown in the 

 table below, in which we have found it more convenient to 

 specify " pale " spots rather than " dusky " spots, seeing that 

 black scales predominate in the second and fourth longitudinal 

 veins. The three main white or cream spots on costa are fairly 

 constant, the apical is always present, but varies in size, 

 while at the base there is one spot only in 18 per cent, of our 

 specimens ; there is, in all, a pale spot on the shaft of the 

 second and fourth longitudinal veins, though it may be very 

 narrow, and, except in the dark varieties, there is no im-
