NEW AMERICAN M I CR 0- LEPIDOPTER A. 

 BY BRACKENRIDdE CLEMENS, M. I». 



OPOSTEGA Zeller. 



Discoidal rxll of irnt(j!f ojkii. Hind wings extvcmely narrow, linear 

 lanceolate. The subcostal vein is central and becomes trifid beyond the 

 middle of the wing, sending an extremely short branch to the costa from 

 the point of subdivision and two long branches, one of which runs to the 

 tip of the wing and the other to the inner margin. The median vein is 

 distinct, curved, simple and nearly joined by the inner extremity of the 

 subcostal vein. The submedian distinct and short. 



Fore wings pointed, almost candulate, but appearing from the cilia to be 

 dilated posteriorly. All the veins simple, parallel^ intliont hranches, sotne 

 much attenuated and none extended to tJie tip of the u-i)uj. Subcostal 

 vein much attenuated, nearly obsolete, equally remote from the costa and 

 the median vein, which is thickened and distinct, and runs through the 

 middle of the wing without reaching the inner margin below the tip. 

 The fold of the wing is distinct, with a parallel, much attenuated nervule 

 above it arising at the extreme base of the median. The submedian vein 

 distinct, thickened. 



Head smooth above. Face mostly on the inferior surface of the head, 

 extremely narrow, hairy beneath and between the antennas in front. Eyes 

 oval, obliquely placed, almost concealed by the antennal eye-caps. Anten- 

 nae with the basal joint expanded into a large eye-cap, which is thin and 

 cup-like anteriorly. Labial palpi hidden on the under surface of the head, 

 short, drooping, with the terminal joint very short. No maxillary palpi. 

 No tongue. 



Q. albogaleriella. — Silvery white. Fore wings with a minute black dot at the 

 extreme ape.r nf the wing. Hind wings and oilia somewhat yellowish-white. 



This insect is very interesting as it is the first extra-European member 

 of the genus, as well as I can ascertain, that has been described. The 

 imago was found on the table under my gas-light on the morning of the 

 9th of July. It was only slightly injured, the stalks of the antennae hav- 

 ing been burned off and the cilia of one pair of wings a little burned. 



None of the larva; belonging to this genus have been discovei'ed.
