 differences than those revealed by the present .somewhat mu- 

 tilated specimen. Even these differences an-. 1 believe, of 

 sufficient importance to demand the establishing of a new 

 family, the StenoxenidaB, an opinion also shared by Mr. .John 

 sou. The description of the m-w genus and species is as fol- 

 lows : 



Stenoxenus johnsoni, new genus iind species. Head narrower than 

 the thorax; when viewed from iu front twice as broad as high . 

 vertex slightly concave, lower half of face sparsely covered with 

 bristles, eyes of female widely separated, deeply emarginate oppo- 

 site the antennae, bare, wholly covered with facets of a uniform 

 size; ocelli absent; proboscis about one-third as long' as heighth 

 of head, very thick, les< than twice as long- as wide: palpi about 

 one-half as long' as heighth of head, pendulous, sub-cylindrical. 

 composed of three distinct joints which are sub-equal in length, and 

 apparently with a very short one between the last two; first joint 

 of antenna? unusually large, compressed, about one and one-half 

 times as broad as long, eimrgiuate at the apex (remainder of an- 

 tennae wanting). Body destitute of bristles, thorax truncate in 

 front, not projecting over the head, destitute of a transverse suture 

 abdomen slightly narrower than the thorax aud nearly twice as 

 long, tapering posteriorly, the apex blunt. Legs slender, destitute 

 of bristles, hind tibia? each bearing a short stout spur at the apex Of 

 the inner side, the others destitute of apical spurs ; front tibia* 

 twice as long as the first tarsal joint, the latter on all the tarsi much 

 longer than any ot the other joints : tarsal claws sin.'ple, empodium 

 and pulvilli wanting. Wings bare, unusually long and narrow, 

 projecting about one-third of their length beyond the tip of the 

 abdomen, venation as iu the accompanying figure: costal vein con- 

 tinued around the tip of the wing, but becoming obsolete on the 

 basal part ot the posterior margin; auxiliary, second and third 

 veins wanting, first vein distinct at its base and apex only, else- 

 where united with the fourth, which is forked near its middle, 

 the upper branch also forked near its base: fifth vein forked near its 

 middle. Halteres normal, color black, polished, lower part of face.
