N0.13M. REVISION OF AMERICAN OELECHIID MOTHS— BUSCK. 815 



The larva feeds presumably on Hypericum frutic(M(i, hut was not 

 observed. The moth was reared accidentally May 5, in a jar contain- 

 ing- another Tineid under observation on the above plant.

With his usual care Dr. Clemens characterized this genus, so that 

 it can be readily and unquestionably recognized even with the type 

 lost. 



It has the lalnal palpi moderate, second joint slightlv thickened, with 

 rough scales beneath, terminal joint as long as second, rather thick, 

 but smooth and pointed. Forewings elongate, pointed; 13 veins, 7 and 

 8 out of 6, 3 and -i stalked; hind wings a little narrower than fore- 

 wings, apex produced, termen emarginate; S veins, 3 and 4 connate, 5 

 approximate to 4, 6, and 7 stalked. 



It was interesting to discover a new species of this genus with iden- 

 tical habits and structure. 



The two known species can be thus separated:

Clemens's type is lost, but I had no difficult}^ in positively identify- 

 ing his species b}^ rearing the characteristic larva, which feeds on the 

 upperside of oak leaves under a thin sheet of silk, with a safety exit 

 to the underside of the leaf, as Clemens described. 



These bred moths, now in U. S. National Museum, agree perfectly, 

 generically and specitically with Clemens' description, and represent 

 without doubt the species. 



They were caref ull}^ compared with and found identical with Cham- 

 bers' type of Gelechia quinqueannulella in the Museum of Compara- 

 tive Zoology in Cambridge, which, furnished with Chambers' label, 

 was found sufficiently well preserved to be easih^ recognizable, and 

 which agreed with his description. 



Chambers' notes on the early stages further verifies this synonymy. 

 Chambers wrote that he was not acquainted with TrupdniKmn prmJenK.^
