50 F. W. EDWARDS — FURTHER NOTES ON AFRTCAN CULrCIDAE. 



general appearance these specimens closely resemble the Oriental Aides butleri, 

 Thee, and the Australasian A. (Skusea) similis, Theo. ; and though the male 

 remains unknown, there is every probability that the present species belongs to 

 Aedes in the restricted sense. The simple claws of the female characterise the 

 subgenus or group Skusea, to which A. pembaensis belongs, and which is differenti- 

 ated from the Culex group (not always very clearly) by the form of the abdomen. 

 In A. pembaensis the scutellum is clothed with flat black scales ; the head has 

 mostly black scales, a few round the eyes and lateral patches i)f variable size being 

 white. Mr. Neave thinks the species must breed in salt water, as the district in 

 which he found it is extremely dry. It is, he says, a very troublesome biter. 



Taeniorhynchus versicolor, sp. nov. 



Q . Head light brownish with golden-yellow narrow scales and dark brown 

 upright ones. Palpi about one-quarter as long as the proboscis, with mainly 

 yellow scales, and some black scales at the middle and apex. Proboscis yellow, 

 black at the tip, with a few scattered black scales. Antennae rather light brown, 

 basal joint almost orange, a few dark scales on the first two joints. Thorax 

 clothed rather sparsely with golden-yellow scales, which extend on to the scutellum ; 

 bristles dark brown. Integument dull brown, lighter in colour on the shoulders ; 

 pleurae light brown with a darker brown stripe. Abdomen banded with purple- 

 black and golden-yellow scales, the former occupying rather more than the apical 

 half of each of segments 2-7. Legs with mixed black and yellow scales ; black 

 rings at the apices of the tibiae and first three tarsal joints ; last two tarsal joints 

 entirely black ; hind tibiae with a broad black ring near the middle ; the scales of 

 the hind tibiae not projecting. Wings clothed with long and rather narrow scales ; 

 these are for the most part blackish, but a few yellow ones are mingled with them, 

 and on the stems of the fork cells, the basal half of the third vein, and the apices 

 of the first and second veins, the scales are almost all yellow. The wing thus has 

 two yellow patches, one just beyond the middle and the other close to the tip, 

 which are conspicuous to the naked eye. The costa and wing-fringe are entirely 

 dark. First fork-cell a little longer than the second, its stem about half as long 

 as the cell. 



$ . Resembles the female, but the dark scales are much more extensive, so that 

 the yellow patches on the wings, so conspicuous in the female, are practically 

 obliterated, and the tarsi are mainly blackish ; the dark bands on the abdomen 

 occupy quite two-thirds of each segment. Palpi exceeding the proboscis only by 

 about half the length of the last joint ; the last two joints are short and about 

 equal in length ; the first two joints are black-tipped, the last almost entirely 

 black. The larger claws of the fore and mid legs each bear a single long tooth.

This species most resembles T. fuscopennatus, but differs in its dull thoracic 

 integument, broad blackish abdominal bands, yellow patches on the wing of the 

 female, shorter terminal joints to the male palpi, etc. T.fuscopennatus has a 

 shiny thorax, bare scutellum, the dark bands of the abdomen narrow and often
