COSMOPTERYX MONTICELLA Chambers. 



Comnoptery.r montlceUa Chambers, Dyar, Cat. N. Am. Lep., 1903, No. (i070. 

 I have examined the tj'pes of this species in the Museum of Compara- 

 tive Zoology in Cambridge, Massachusetts, and in Professor Fernald's 

 collection. The}' are identical with a specimen determined by Lord 

 Walsingham in the U. S. National Museum from California. Chambers's 

 types came from Colorado. The antenna3 have the following colora- 

 tion: Apical 5 joints white, following 7 joints black, nextl white, next 

 2 black. 



COSMOPTERYX NITENS Walsingham. 



Cosmopteryx nitens Walsingham, Dyar, Cat. N. Am. Lep. N. Am., 1903, No. 6071. 



Professor Fernald was so kind as to give me parts of the type mate- 

 rial of this species during a visit to his home in 1902. Besides this 

 specimen, which I compared with Lord Walsingham's type in England 

 last spring, there are others, probably all from the same series, in the 

 L^^. S. National Museum from Texas. 



It is a striking species, easil}' distinguished by the longitudinal black 

 streak in the yellow cilia, as well as by the coloration of the antenna', 

 which is as follows: Two apical joints white, 7 succeeding joints black, 

 next 1 white. 



COSMOPTERYX CLANDESTINELLA, new species. 



. Antennae blackish brown; each joint of basal half dotted with silvery 

 white; the last four apical joints white, the five preceding ones black, 

 followed by two or three white joints. Labial palpi blackish brown, 

 silvery on the inside, and with two longitudinal silvery white lines. 

 Face silvery white, iridescent. Head and thorax dark brown, strongly 

 metallic. Forewings ])lackish brown; basal half without any white 

 markings, but with two oblique, converging, short, broad, somewhat 

 confluent, bluish metallic streaks, equidistant from the base, one on 

 the subcostal vein, the other, and somewhat larger, below the fold. 

 Just outside the middle of the wing is a narrow, complete violet and 

 silvery metallic fascia followed by a short space of the ground color; 

 then follows the usual reddish yellow fascia, which has an angulated 

 posterior edge, being much and abruptly prolonged along the costal 

 edge; it is limited posteriorly by a large violet metallic dorsal spot and 

 by a few metallic costal scales, which are in turn followed ))y a white 

 costa streak prolonged into the cilia. Apical part of the wing dark 

 brown, with a small silvery white dorsal dash just before the tip. 

 Hindwings dark fuscous. Abdomen blackish l)rown. Legs silvery 

 white on the inner side, black barred with white on the exterior side; 

 posterior tibia* with three long erect tufts of black hairs; tarsi black, 

 each joint tipped ^\ ith silvery white. 

 Alar expanse. — 8 mm.
