Eyes naked. Abdomen superficially divided into 3 segments ;

 ternally gibbous. First cubital areolet distinct from the praediscoidal ; 

 pobrachial shorter than the prsebrachial ; recurrent nervure sub-

Finely rugulose, abdomen striolated. Head rufo-testaceous, 



eyes and stemmaticum dusky; thorax and abdomen variable, 



usually testaceous with the metathorax and 3d abdominal segment 



fuscesceut ; legs testaceous, often with the hind femora at the apex, 



* The following exotic species has never been described. It is 

 remarkable for having the terebra more exserted than usual in this 

 subfamily : — 



Phanerotoma noctivaga, n. s. 



Testacea, coriacea, oculis (in viva) viridibus ; antennarum apice, 

 metathoracis litura, abdomine postice, plerumque segmentorum 

 primi et secundi limbo, tibiisque poaticis apice, fuscescentibus ; 

 feminse segmento anali emarginato ; alis hyalinis, stigmate pallido 

 vel fusco-maoulato, terebra abdomine breviore, tenuissima, falcata. 

 J 5 . Long. 1 — 1| ; alar. exp. 2 — 3^ linearum. 



Antennae in both sexes 22-jointed, of the $ , as long as the body, 

 of the (? , longer. Head wider than the thorax, transverse ; vertex 

 flat ; clypeus entire, obtusely rounded, discrete, with two impressions 

 at the base. Body very finely rugulose, almost coriaceous ; abdo- 

 men very finely rimulose, constructed like that of P. dentata ; the 

 gibbosity before the apex, marking the limit of the 3d segment, 

 more conspicuous in the (^ . Terebra as long as f of the abdomen, 

 curved upwards, very slender and whitish, the valves at the ajiex 

 fuscescent. Legs nearly white, only the tips of the hind tibiae 

 fuscescent ; hind femora and tibiae incrassated ; uitermcdiate tibiae 

 gibbous on their outer edge before the base. 



Frequent in the Island of Antigiia, flying by night. I took three 

 males and three females at different times, attracted into the house 

 by lamps, and saw many more.
