INSECUTOR INSCITI^ MENSTRUUS 87 



founded upon females. Later he describes what purports to 

 be the male of it ; but the specimens have evidently been 

 wrongly associated, for the male is a Culex, different from 

 any of the species listed and apparently close to the North 

 American Culex restuans Theobald. The new name is ac- 

 cordingly proposed, founded upon Brethes's figure of the 

 genitalia ( Anal. Mus. Nac. Hist. Nat. de Buenos Aires, xxviii, 

 314, fig. fi, 1916). 



Aedes lynchii Brethes. 



Culex lynchii Brethes, Bol. Inst. Ent. y Pat. Veg., i, 30, 1912. 



The females belong to Aedes, of the tropical group of 

 Ochlerotatus typified by scapularis Rond. The male is un- 

 known. 



In the monograph,^ we show that Heferonycha dolosa Lynch 

 Arribalzaga is an Aedes, but were not able to indicate the 

 identity of the species. It appears to have been not uncom- 

 mon, and should certainly recur. It seems to me that lynchii 

 Brethes is probably the species in question. This is a medium- 

 sized Aedes with black tarsi, the mesonotum with a broad 

 central band of light golden scales, the sides broadly scaled 

 with dark brown. The abdomen is unhanded above, with small 

 lateral basal segmental white spots, the venter whitish scaled, 

 with apical black bands posteriorly and a slender black broken 

 median line. Lynch's description is anything but clear. He 

 emphasizes the male structures and scarcely describes the 

 coloration at all. The impression one gets is that he is de- 

 scribing a male Culex, and this accounts for the reference of 

 Heteronycha dolosa to the synonymy of Cidex quinqiiefas- 

 ciafus Say made by many authors. However, his female 

 clearly had toothed claws. He separates Cidex and Hetero- 

 nycha on the basis of the former having simple claws in both 

 sexes, the latter with toothed claws in both sexes. Now the 

 males have toothed claws in both Cidex and Aedes, so it is 

 clear that Lynch made an error. What he had before him as 

 the male of Culex cannot now be said ; but it strikes me as
