neighbourhood of Manaos. They were all taken between the hours

Uranotacnia geomelrica, Theobald 
(Plate XI, fig. 3) 
This very handsome mosquito was commonly found in the 
neighbourhood of swamps and large puddles within the city of 
Manaos and also in its environs. It was usually associated with 
Culex faligans, Ccllia albipes, and occasionally with Stegomyia 
calopus. At Iquitos, Peru, it was also common in the swamps near 
the villages of San Juan and San Miguel. 
The majority of the specimens were captured out of doors ; but it 
occurred, not infrequently, in dwelling-houses and also in the Hospital 
da Portugueza Beneficente, Manaos. For details regarding the distri¬ 
bution of this mosquito in the latter locality, see map opposite p. 54. 
Goeldi in his delightful memoir* makes no reference to this insect. 
The type, however, was caught by Dr. Lutz at Cubatao, near Santos, 
Brazil. Dr. Lindenbergt also records this species from Manaos ; but 
there is apparently no previous reference to its occurrence at Iquitos, 
Peru. 
Uranotaenia pulcherrima , Arribalzaga 
This beautilul little species occurs freely at the swamps along the 
Igarape Castelhana, especially so in the one by the old cemetery, 
Manaos. The locality is a new and hitherto unrecorded one. 
Urano/acnia lowii, Theobald
