JANUARY, 1860. 107 



wing, with a long and distinct marginal nervule from near 

 the base, one from the middle of the secondary cell, and three 

 from the end of it to the costa. Three nervules from the 

 discal nervure to the inner margin beneath the tip. The 

 median without branches; beyond the discal it proceeds to 

 the inner margin, as a single short vein ; perhaps it may be 

 bifid. The submedian is simple. Hind-wings lanceolate, 

 clothed with scales, with the discoidal cell closed by a very 

 faintly indicated nervure. The costal nervure is long, and 

 extends nearly to the tip of the wing. The subcostal is 

 simple, and wanting from near the origin of the discal ner- 

 vure, where it is slightly produced 

 inwardly, but well indicated thence 

 to near the tip. The discal ner- 

 vure gives rise to a discal branch, 

 which quickly becomes bifid, and 

 its branches well defined near to 

 the tip, above and beneath. The median is well indicated, 

 and is three-branched, the last very faintly connected with 

 the second. No submedian nervure.* 



Size very small. Head rough and hairy above and in 

 front. Ocelli none. Eyes rather large, round and salient, 

 not set on a naked circular portion of the head, nor with a 

 naked space above the eyes. Antennae about one-half as 

 long as the anterior wings, inserted laterally, and microscopi- 

 cally pubescent beneath ; basal joint moderately long, stalk 

 roughened with scales. Maxillary palpi rather long and 

 folded. Labial palpi moderate, slender, smooth, cylindrical, 

 separated and somewhat drooping ; the third joint nearly as 

 long as the second, which has a few bristles at its end and 

 beneath. Tongue ? 



D. velatella. Labial palpi dark brownish. Head brownish- 

 gray. Antennas grayish-fuscous, with the basal joint whitish, 



* The sketch of the neuration I received from Dr. Clemens has apparently 

 been made from a specimen only partially denuded, and is not therefore com- 

 plete. H. T. S.
