234 Teneina of the United States. 



or five minute, violet, silver specks in the space between the fascia. 

 Behind the oblique fascia, the wiqg is darker brown, with an oblong, 

 violet, silver spot at the base of the dorsal cilia, and another at the 

 apex, passing into the snow-white apical cilia. The cilia are, other- 

 wise, dark brown. The under surface of the thorax and abdomen, and 

 the basal joints of the anterior legs, are silvery or pale golden, or like 

 burnished steel, according to the light. Anterior tibite and tarsi, dark 

 brown before, silvery white behind; posterior and middle legs, dark 

 brown, with the tibise and tarsi annulate with silvery white, and a 

 silvery white streak on the posterior tibise behind. Als. ex. scant, 4 

 lines. Taken at Covington, Ky., May 22, in a season, at least, two 

 weeks later than usual. 



It is the only specimen of the genus that 1 have taken in six years 

 of active collecting. 



Glyphipteeyx. 



Of this genus as of Cosmopteryx six years of diligent collecting has 

 yielded but a single specimen of a single species and it was taken 

 at the same time and place with the Cosmopteryx (supra) viz.: 

 Linden Grove Cemetery, Avhei-e more than nine-tenths of my Ken- 

 tucky Micros have been taken, and at a time when I had given up all 

 hope of finding there anything new. At the same time and place 

 I found a new species of Gracilaria. Whilst this locality produces an 

 abundance of species of most genera, a few genera seem almost un- 

 represented. As for instance I have taken here but a single specimen 

 of Anaphora, whilst near Mammoth Cave I find several species, and 

 took more specimens of that genus than of all others put together 

 during the two weeks in July that I spent there. 



G. exoptatella, n. sj). 



This insect was taken at the same time and place with the above des- 

 cribed Cosmopteryx and like it is the only specimen of the genus that I 

 have met with here, and therefore conies like one born out of due time 

 and none the less welcome. It is so near impigritella, Clem., that befi)re 

 I gave it a close examination I took it to be a specimen of that species. 

 But Dr. Clemens says that the first (the large curved silvery dorsal 

 streak is dark margined on both sides in impigritella, whilst in this speci- 

 men its margins are no darker than all of the basal portion of the wing, 

 except close to its apex, from which they pass backwards along the 

 middle of the wing for a short distance, but in some lights they are not
