gives the antennae a very heavy and thick appearance ; in the female the 

 whorls are quite loose. Wings much broader than in the other species, 

 and more blunt at tip. The inferior pair of ^ appendages are very long, 

 slender, and gradually tapering, strongly curved upward and nearly 

 black, with white hair beneath, the superior pair not half so long, tapering 

 and diverging. Cannot make out the structure of the $ ventral plate. 

 Length of wing, 1.6 mm. 



Not uncommon on the bark of large trees in a damp woods, but 

 difficult to capture ; near Sea Cliff, N. Y. 



Readily known by its small size, uniform gray colour and broad wings, 

 which, when at rest, are folded roof-like over the body. 



Psychoda superba, nov. sp. 



Black, the thorax clothed in the middle with black hair, and on the 

 sides with snow-white hair, in some cases it appears to be all white- 

 haired ; the abdomen with long, dense, black hair ; the wings with 

 blackish hair and patches of erect white hair, the tips of the posterior 

 veins with a black dot and a white spot between them, some of the 

 anterior veins also usually tipped with a black dot ; most of the fringe on 

 the anterior margin is black, but near tip and on posterior margin, gray or 

 whitish, where it is four times as long as the width of a cell ; the legs are 

 black, with black hairs and scales and a few white scales at the tips of the 

 joints. The c^ antennae are black, quite thick, shorter than the width of 

 wing, with short black and longer gray, appressed hair ; in the ? the 

 antennae are more slender and more sparsely clothed. There are a few 

 patches of white hair on the head. The wings are quite broad, but hardly 

 as acute at tip as in some species. The genitalia are not prominent, 

 being concealed by the long black hair of abdomen. The inferior 

 appendages of the $ are black, approximate, short and blunt ; they are 

 not much more than one-half as long as the diameter of the tip of the 

 body, and but little up-curved ; the superior pair are nearly as large, 

 stout, and tapering to a point ; they are wide apart at base, but curve 

 toward each other. The ventral plate of $ is broad, yellow at tip, and 

 broadly notched, but the notch is but one-half as deep as wide ; the ovi- 

 positor is twice as long as plate and a little curved. Length of wing, 2.5 

 to 2.9 mm. 



Common on the bark of large trees in woods. June. Sea Cliff, N. Y.
