As explained previously (p. 911), it seems to me unwarranted to make 

 Tric/totaphe setosella Clemens a synonym of this species. Lord Wal 

 sing'ham, who made it so, did not have Clemens' type, but came to a 

 conclusion from a specimen in C. T. Robinson's collection, labeled 

 setosella. It seems more reasonable to believe this specimen wrongly 

 labeled and to accept Clemens' word, that his setosella is a Trichotaphe 

 .species. 



I have bred good series of the present species from Eupatorimn 

 in the District of Colum})ia, and in U. S. National Museum are besides 

 specimens from the following localities: Florida (Dyar), Texas (Beut- 

 enmiiller), Arizona (Schwarz), Kansas (Crevecoeur), New York (Banks), 

 Virginia and Maryland (Busck). 



The males of this species have an interesting secondary sexual char- 

 acter, which 1 have not noticed in any other Gelechiid, namely, a 

 strong pencil of long yellow hairs on thorax just below costal base of 

 fore wings. This pencil can be expanded into a whorl of hairs which 

 envelops the eyes and base of the palpi as a veil. 



If — what is to be presumed — this pencil in the male is thus expanded 

 during courtship, the insect may indeed be said to have reached in 

 this respect the standpoint of man, whom love makes blind. 



The larva feeds in a leaf folded from the edge and pupates within 

 the fold. When full grown it is about 15 mm. long, cylindrical, taper- 

 ing slightly. Head polished, jet black, longer than wide, semihori- 

 zontal, mouth parts brownish. Width of head, 1 mm. 



Thoracic shield polished black, straight in front, rounded posteriorly, 

 twice as wide as long. The rest of the body is greenish white, turning 

 at maturity to wine red with white veins; tubercles small, black, hairs 

 short black, anal plate only slightly cornified, light brown. Legs nor- 

 mal, first thoracic feet black, the others whitish; abdominal i)rolegs 

 with complete circle of small hooks. 



Two generations, at least, are found in the locality of Washington, 

 the imagoes issuing in July and late in September.
