76 A Monograph of Culicidae. 



with yellow and black scales ; on the costa are six black areas, 

 the apical one smaller than the second, the second than the 

 third, the fourth about equal to the apical one in size ; the two 

 basal ones small, the first and second extend evenly on to the 

 first long vein, the third is broken on the first long vein near the 

 base (as in P. costalis), the fourth extends evenly on to the sub- 

 costal and first long vein, the two basal ones do not extend below, 

 the branches of the second vein are dark scaled except at their 

 apices and at the commencement of the fork, two dusky spots on 

 the stem, one beneath the large costal spot (3rd). The third 

 long vein has three black areas, one apical, a large and small 

 one near the base ; two black spots on each branch of the fourth, 

 stem all black but for two small yellow spots ; the fifth is all 

 yellow except a black spot at the base and apex and three black 

 spots on the upper branch ; the sixth has three black spots ; 

 fringe brown, with a yellow spot where each vein joins the costa 

 except the sixth. Halteres pallid with slightly fuscous knob 

 with small grey scales. 



Length, 5 to 5 • 5 mm. 



$ . Palpi with the two apical segments swollen, of about 

 equal size, clothed with white scales at their apices, brown 

 elsewhere, the antepenultimate segment has also a small white 

 apex and a small white spot on one side towards the base, two 

 apical segments and apex of the antepenultimate with long 

 golden-brown hair-tufts ; antennae yellowish-grey, with deep 

 brown verticillate hair, giving a banded appearance ; legs and 

 wings much as in the female, but one less spot on the hind 

 metatarsi ; fore ungues very unequal, the larger curved and 

 uniserrate ; mid apparently small and simple ; hind small, equal 

 and simple. 



Length, 5 ' 5 mm. 



Habitat. — Natal (Dr. Power). 



Observations. — Described from a perfect male and female. 

 The ornamentation of the legs is very marked. The specimens 

 were taken in Durban, where malaria was prevalent at the time, 

 and the female had fed from a patient suffering from that 

 disease (malignant tertian). 



It will probably prove to be a malaria carrier in Natal with 

 P. costalis, Loew.
