Neither specimen is perfect, and the male especially is in 
bad shape, 'but there can be no reasonable doubt as to the genus 
or that the species is new. 
Described from one male and one female sent by Lieut. 
W. H. Duncan, Assistant Surgeon U.S. Army, with specimens 
of Chamberlainii; it is an extremely small mosquito, quite as 
small as S. minuta, Theob., or S. amesii , Ludlow.”

Head clothed with small flat scales and a group of upright 
forked ones behind. Palpi of female thin, longer than in culex, 
of the male long, longer than the proboscis composed of two 
segments, the apical one short and clavate, with thorn-like 
chaetae; proboscis curved and swollen apically,,. shorter than the 
body ; antennae of female pilose, of male densely plumose. 
Thorax and scutellum with narrow-curved scales, metanotum 
nude; blunt curved chaetae project over the head. Male 
genitalia with normal narrow claspers. 
Fork-cells small ; the marginal cell of peculiar form in both 
sexes swollen out in the middle, contracted near apex of wing
