of that species should always distinguish readily even the most 

 aberrant males from cubensis, while the ovipositor characters of the 

 females show the two species to belong to different subgenera. 



Little has apparently been known of the life history of the present 

 species, and it is probably due to the fact that the majority of speci- 

 mens collected have been taken flying to lights at night that so few 

 brachypterous specimens have been previously recorded. 



Types: 4 c?", 5 9; Cuba. (Poey.) [Saussure Collection.] 



We here describe a female from Cuba, taken by Gundlach, and now 

 in the Scudder Collection. 



Size small, form slender for the genus; head small but full and 

 rounded, wider than cephalic width of pronotum. ]\Iaxillary palpi 

 of much the same form as in .V. fasciatus, but with joints not quite 

 as much produced. Eyes broad-ovate, very mildly prominent, though 

 somewhat more so than in A^. jmlustris. Pronotum of much the same

proportions as in fasciatus, but of smaller relative size to rest of 

 body. Tegmina long, extending beyond end of abdomen, apex of 

 same dorsal in position, distal margin of dorsal field rotundate acute- 

 angulate, longitudinal veins not very prominent, cross-veinlets very 

 faint. Wings absent. Ovipositor more than two-thirds as long as 

 caudal femur, distinctly though very feebly arcuate; apex of same 

 very narrowly sublanceolate, with that portion formed by the dorsal 

 valves armed, the upper margin serrulate, these serrulations very 

 closely arranged, regular, minute, sharp. Caudal femora with 

 greatest (meso-cephalic) width contained about three times in 

 length. Spines of caudal tibiae more slender than in fasciatus, not 

 quite as slender as in palustris. 



A male in the Scudder Collection, bearing the same data as the 

 female here described', affords the following additional information. 



Size very slightly smaller, proportions very much the same. The 

 tegmina are translucent, and when in repose the dorsal fields are hemi- 

 elliptical in outline. Wings very long. Proximo-internal spine of 

 caudal tibiae similar to that oi fasciatus.
