CHARACTERISTICS OF LARVJ] OF AXOPHELINA. 143 



made, whereas in Theobald's figure is shown a spot on the 

 anterior or upper branch which is not alluded to in the text. 

 The wing figured in ' Monograph of the Culicidas ' is 3'9 nun. 

 in length, that of Natal specimens but little over 3 mm. In 

 the light of the great variation in size which we find in 

 fuuesta and paludis, this appears to be no obstacle to 

 placing our specimens in the same species. We have but few, 

 and are unable to state how much variation in Aving pattern 

 occurs ; but we may note that we have observed one specimen 

 with an additional white spot on the fringe opposite the 

 termination of the third longitudinal vein, and a second with 

 yet another spot opposite the anterior branch of the second 

 fork cell. There are also observed in some specimens four 

 narrow white bands on palpi instead of three. 



The Larva (PI. XX). — Determined on four specimens, 

 drawn from comparison of four. 



General appearance. — A slender larva with much ]'ig- 

 ment in median strip. 



Antenna. — Xo branched hair on shaft, terminal spines 

 equal, hair divides into three branches. 



Frontal hairs. — Three pairs ; anterior median and pos- 

 terior vary (PI. XX, fig. a). In three of the four specimens 

 the external hair is dendriform (PI. XX, fig. d), in the fourth 

 (fig. e) it is rather penniform in shape. This larva was taken 

 from a small collection, of which some five or six developed 

 into imago of squamosa. The exact shape of the hair is 

 scarcely appreciable under a lower magnification than x 100, 

 and is readily overlooked, and can scarcely be differentiated 

 in the living larva. There is no other difference. 



Palmate hairs. — Rudimentary on thorax (PI. XX, fig. c), 

 well developed on the first abdominal segment and excep- 

 tionally large second to the seventh inclusive. The leaflets 

 are relatively narrow and few, about sixteen in number (as in 

 jacobi) in contrast to ar den sis, in which they are broad 

 and numerous, about twenty-five. Average radius 0"144mm. 



Average relation of filament to total length of filament and 

 leaflet as 0"36 to one ; maximum, 0'40; minimum, O'oo.
