NEW MOSQUITOES FROM PERU 61 



The genitalia are plainly of the Culex type, as shown by the presence 

 of the prominence bearing a leaf-like appendage and the tufted harpes. 

 The side pieces are specialized and curiously elaborated, but the undi- 

 vided harpagones and the presence of the lobe indicate a low origin for 

 this form. The lobe has disappeared from all the Culex proper, being 

 seen only in low forms which are not truly Culex, such as C. dyari, 

 C. melanuTus, and the species of Culiseta. In these the characteristic 

 structures of Culex have not appeared ; but they are well shown in 

 Phalangomyia. This genus, therefore, forms a connecting link between 

 Culiseta and Culex, nearest to the latter and modified on its own pecu- 

 liar lines. 



Aedes epinolus, new species. 



Female: Proboscis black, with a rather broad white ring near the 

 middle. Palpi black, white at tips and in the middle. Occiput clothed 

 medianly with narrow curved yellowish scales, a strip of broad black 

 scales laterally ; cheeks white scaled ; dorsally many erect truncate yel- 

 lowish scales. Mesonotum clothed wath deep reddish brown scales with 

 golden luster. Abdomen dorsally black seeded, the segments with very 

 narrow, basal, yellowish white bands which do not reach the sides ; a 

 series of small yellowish spots dorsally, a pair on the middle of each seg- 

 ment ; a series of large pure white spots placed medianly at the sides of 

 the segments ; venter yellowish scaled, the apices of the segments white 

 scaled. Legs black, the tarsi with basal pure white rings, broad on the 

 hind legs and with the last joint white on the basaJ half. Claws toothed 

 on the front and middle legs, simple on the hind pair. 



Length: Body about 3.5 mm., wing 3 mm. 



Ventanillas and Ancon, Peru, 3 and 4 Feb., 1914 (C. H. T. Town- 

 send). Twenty-five females. Type, No. 18362, U. S. Nat. Mus. 



A coast form, closely related to Aedes tatniorhynchus Wied. and 

 Aedes niger Giles, and holding a position intermediate between these 

 two with reference to extent of the tarsal rings. In t&niorhynchus the 

 last hind tarsal is all white ; in niger it is almost wholly black. A edes 

 niger occurs exclusively in the Antilles and in southern Florida ; 

 therefore it and the new form are separated by territory (Panama) 

 in which only the true t&niorhynchus occurs. It follows that the new 

 form can not be considered a derivative of niger. Aedes nociurnus 

 Theobald (Mon. Culic, III, p. 159, 1903). from Fiji, is also closely
