156 THE ENTOMOLOGIST. 



CuLEx HiRsuTiPALPis, Theobald. 

 (Mono. Culicid. i. p. 378, 1901.) 



Several males and females from Bihe, Angola. The males 

 differ from the type in that there is no pale band at the apex of 

 the palpi. 



My figure of the male ungues (Mono. Culicid. i. p. 378) were 

 drawn from a pinned specimen in which they could not clearly 

 be seen. When mounted and examined flat the tooth of the 

 larger fore and mid ungues is seen to be large and outstanding, 

 almost at right angles to the claw, and the tooth of the smaller 

 one is more pronounced and nearer the base. The series also 

 shows great variation in size, some specimens being one-third 

 less than the type. 



Genus Heptaphlebomyia, Theobald.* 



(Mono. Culicid. iii. p. 336, 1903.) 



This genus was described from a single female. The fresh 

 material sent from Angola by Dr. Greighton Wellman has enabled 

 me to add fresh generic characters to those already given. The 

 males sent by the collector do not agree with the females, and I 

 am not sure if they are of the same species. 



Characters of the Genus. — Head clothed with narrow-curved scales, 

 and upright forked ones, except at the sides, where they are small and 

 spathulate. Palpi of the female small but prominent, in the male 

 acuminate, the last two segments hairy. Thorax clothed with narrow- 

 curved scales, and also the scutellum and prothoracic lobes ; the 

 pleurse in the female with patches of flat scales, which end in a sharp 

 point ; in the male they are rounded apically. The wings have the 

 typical Culex venation, but the females have a distinct seventh long 

 vein, scaled for part of its length with rather large elongated flat 

 scales, which apparently vary in number from ten to fifteen. The 

 scales of the wing are rather broader than in Culex, especially in the 

 apices of the veins, including the branches of the fork-cells. In the 

 males there does not seem to be a scaled seventh vein, but the sixth is 

 markedly bent at right angles near the edge of the wing. 



The two chief features in the genus are the presence of a 

 scaled seventh vein in the female, and the peculiar form of the 

 scales on the pleurse, which I have not seen in any other 

 Culicids. There is a superficial resemblance between the males 

 and females, but the absence of the scaled seventh vein in the 

 males makes it doubtful if they really belong here, although 

 evidently they were taken together by the collector. 



■'- Since this was sent to press, two very marked new species have 

 been sent me from Madagascar. The descriptions will shortly appear in 

 the 'Arcliiv der Parasitologie,' in a paper on Madagascan Culicidte by 

 M. Veutillon.
