NEW MOSQUITOES FROM PERU 



{Diptera, Culicida) 

 By HARRISON G. DYAR and FREDERICK KNAB 



Very little is known of the mosquito fauna of Peru, although great 

 diversity of conditions in an equatorial country promises great richness. 

 The only species heretofore known to us from Peru have been the fol- 

 lowing, received for determination at different times : Culex quinquefas- 

 cfatus Say, Ancon, 3 Feb. 1914 (C. H. T. Townsend) ; Aedes leu- 

 comelas Lutz, Rio Charape, 18 Sept. 1911 (Townsend) ; Aedes calo- 

 pus Meigen, Ancon, 3 Feb. 1914 (Townsend); Anopheles pseudo- 

 punctipennis Theob., San Bartolome, 5,800 feet, 16 Apr. 1913 

 (Townsend) ; Anopheles boliviensis Theob., Rio Charape, 1 3 Sept. 

 1911, Rio Huascaray, 22 Sept. 1911 (Townsend). To these we can 

 now add the following new forms. 



Phalangomyia, new genus. 



Proboscis long, uniform, nearly straight in both sexes, in the male v^ath 

 a false joint near the middle. Palpi short in the female ; in the male long 

 and slender, acuminate. Antennae filiform in the female, the joints with 

 basal whorls of short sparse hairs ; in the male sparsely plumose, rather 

 long. Clypeus well developed, nude. 



Prothoracic lobes small, lateral. Mesonotum elongate, convex, with 

 longitudinal series of coarse hairs on the disk and laterally. Scutellum 

 weakly trilobate. Postnotum convex, prominent, nude. 



Abdomen subcylindrical in the female, truncate at tip ; in the male 

 long, slender basally, depressed outwardly. 



Legs slender throughout and very long, the three pairs progressively 

 longer but not differing greatly in length ; femora and tibiae of all three 

 pairs of legs of about equal length ; first joint of hind tarsi slightly shorter 

 than the tibia ; scraper of hind tibia without complete row of spines. 

 Claws simple and small in the female ; in the male large, unequal, and 

 each vyrith a single tooth on the front and middle legs. 



Wings with the venation as in Culex. 



Phalangomyia debilis, new species. 



Female : Proboscis clothed with dark brownish scales. Palpi about 

 one-sixth as long as the proboscis, dark scaled, with a few coarse bristles. 

 Clypeus prominent, narrow, rounded anteriorly, dark brown. Antennae
