the i)ossession of a male specimen, may bring to light other 

 differences than those revealed by the present somewhat mu- 

 tilated specimen. Even these differences are, I believe, of 

 sufficient imjwrtance to demand the establishing of a new 

 family, the Stenoxenidae, an -opinion also shared by Mr. John- 

 son. The description of the new genus and species is as fol- 

 lows : 



Stenoxenus johnsoni, uew genu? and species. Head narrower than 

 the thorax: when viewed from in front twice as broad a.s 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 <overed with facets of a uniform 

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

 of head, very thick, less than twice as long as wide: palpi about 

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

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

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

 of antennae unusually large, compressed, about one and one-half 

 times as broad as long, emarginite at the apex (remainder of au- 

 tennje 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 and nearly twice as 

 long, tapering posteriorly, the apex blunt. L^s slender, destitute 

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

 the inner side, the others destitute of apical spurs : front tibiae 

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

 longer than any ot the other joints : tarsal claws simple, 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 ai'ound the tip of the wing, but becoming obsolete on the 

 basal part of the posterior mai'gin : 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, 

 mouth parts, coxae, front and middle femora and the hind ones ex- 

 cept their apices, also the middle tibiae and their tarsi yellow, 

 apices of hind femora, front and hind tibiae and their tarsi brown; 

 halteres brown, their bases yellow; hairs of the body very short, 

 light yellow: wings whitish-hyaline, the veins duskv yellowish, 

 those near the posterior margin only slightly lighter in color than 

 those alonof the costa, apical portion ot first vein faint. Length 3 

 mm. Delaware Water Gap, New Jersey. A single female speci-
