710 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxx. 



Other specimens are from Sea Cliff, New York (Banks), and from 

 Washington, District of Columbia (Busck). 



The coloration of the antennte, which, as in the foregoing species, is 

 not quite constant, is as follows: 3-4 last joints white, 5-S next joints 

 black, 1 next white, 2 next black, 8 next white. 



I believe this species feeds on morning-glor}^ though 1 have not 

 succeeded in breeding it. There is a Co.sinopteryj' mine and larva not 

 uncommon in this plant around Washington, and 1 have repeatedlv 

 taken the present species on such plants. 



COSMOPTERYX ATTENUATELLA Walker. 



Cosmopteryj' attenuatella Walkek, Dyar, Cat. N. Am. Lep., 1903, No. 6068. 

 The tvpe of the synonvm Coxinoptery.r lei^pedeza^ W^alsingham, 

 from Texas, is in U. S. National Museum; also a specimen from Palm 

 Beach, Florida (Dyar) and several from Santo Domingo, West Indies 

 (Busck). The antennal coloration is as follows: 4 last joints white, 

 5 next joints black, 1 next white, 1 next black. 



COSMOPTERYX IPOMCE/E Busck. 



Co.v)iopteri/x ipomceie'BvscK, Dyar, Cat. N. Am. Lep., 1901^, No. 6067. 

 The type of this species from Palm Beach, Florida (D3'ar), is in the 

 U. S. National Museum and has the following antennal ornamentation: 

 3-[4?J last joints white, 5 following ])lack, and 1 succeeding white. 



COSMOPTERYX UNICOLORELLA Walsingham. 



Cosmopteryx unicolorelki WALfsixonAM, Dyar, Cat. N. Am. Lep., 190:^, No. 6074. 

 I have examined the unique type of this species in Lord Walsing- 

 ham's collection at Merton Hall, England. It can not be confounded 

 with any other described American species through its total lack of a 

 yellow or orange fascia. The species was described from California 

 (Walsingham) and has the antenna^ colored thus: 4 apical joints white, 

 the succeeding 5 or (5 black, the next 1 joint white, the following 2 or 

 3 black, and the next 3 white. 



COSMOPTERYX QUADRILINEELLA Chambers. 



Cosmopteryx quadrilineella Chambek.s, Dyar, Cat. N. Am. Lep., 190:i, No. 607:1 

 The t3'pe of this verj- distinct little species from Texas is in the 

 Museum of Comparative Zoology, in Cambridge, Massachu.setts, 

 received from Chambers. It is a true Coi<moptei"yx^ easily distin- 

 guished from all other described American species by the suffused 

 yellow fascia, which spreads all over the apical half of the wing and 

 surrounds the metallic spots, instead of being limited by them as is 

 usual. 



The anteniue are lost in these types, which are the onl}' specimens 

 known tp me.
