WYEOMYIA CODIOCAMPA 101 



surface. The summer broods mature in about a month, and there are probably 

 three if not four series, but the broods overlap so much that the breeding is 

 practically continuous. Late in the season the adults select the new leaves for 

 oviposition even if they are yet dry." 



To Dr. Smith's observations we can add that the length of larval life, as in 

 related forms, is very variable, depending upon the food in the form of insects 

 which are drowned in the leaf -pitchers, naturally a variable factor or one which 

 may fail altogether for a period. We have kept larvae alive in the original water 

 and without food for nearly an entire year. As the eggs are laid in the dry, 

 young leaves the egg-period likewise must be variable, depending upon the 

 advent of water in the leaves. 



North America, Canada to Alabama, probably coextensive with range of its 

 host plant, Sarracenia purpurea.

This is the only known sabethine mosquito inhabiting temperate latitudes. 

 It is of perfectly normal structure, and has close allies in the tropics, inhabit- 

 ing the leaves of Bromeliacese. Our species was first discovered in the larval 

 state, but its peculiarities passed unnoticed, ovring to the imperfect state of 

 the knowledge of the subject at the time. It was finally recognized as a new 

 species, but was placed in the genus Aedes, on account of the short palpi of 

 both sexes. After the erection of the sabethid genera by Mr. Theobald it was 

 determined to belong to the genus Wyeomyia by Mr. Coquillett, although first 

 published under this name by Doctor Pelt. Mr. Theobald lately places it 

 in Dendromyia, owing to the comparatively broad wing-scales, but we consider 

 this genus synonymous with Wyeomyia. Mr. Coquillett identified specimens 

 from Florida, bred from Bromeliaceae as this species, and this record has been 

 published by Smith and Theobald; we here identify these specimens as Wye- 

 omyia vanduzeei. Mr. Coquillett had also identified several other species from 

 Florida, the Bahamas and Cuba as Wyeomyia smithii. These identifications, so 

 far as we know, have been published by Smith for Florida, referred here to W 

 vanduzeei (p. 65), by Dr. Pazos for Cuba, which will be found here under W. 

 violescens (p. 79), and by Dr. Cofiin for the Bahamas, which will be found here 

 under W. hahama (p. 62). Theobald further records Wyeomyia smithii from 

 Eio de Janeiro, Brazil, but this is very clearly an error of identification. Pery- 

 assu followed Theobald, and as he quotes his description of our species, we are 

 obliged to cite him in the bibliography.
