66 WILLIAM G. DIETZ, M. D. 



anteriorly, Forewings pure white, markings dark fuscous brown ; a small dot 

 at extreme base of costa, an oblique spot very near the base, reaching the fold 

 where it is met by an oblique line extending from a small spot at the anal angle; 

 just before the middle of the wing is a large, oblique spot which reaches the 

 middle of the disc where it forms an acute angle with an equally pronounced 

 spot which begins before the middle and within the dorsal margin; midway 

 between the two last-mentioned costal spots is another costal spot and in the 

 outer half of the wing three more, the last of which extends as a line along the 

 base of the cilia ; in the apical part of the wing and nearer the dorsal margin is 

 a streak which becomes bifid before the apex, one branch going to the costal the 

 other to the dorsal margin just before the apex, a number of dots, irregular in 

 size along the dorsal margin, there are some irregular strigulations, especially in 

 inner half of wing and some longitudinal lines in the outer, consisting of dark 

 scales. Cilia white, traversed by three narrow costal and three wider dorsal 

 bars, dark brown in color. Underside fuscous, showing markings of upper side. 

 Hindwings under 1, silvery gray ; cilia concolorous with ochreous tinge, under- 

 side of body silvery white, tinged with ochreous. Legs yellowish, anterior more 

 or less fuscous externally, femur and tibia of middle pair with fuscous patch 

 externally ; tarsi spotted with fuscous. 

 Exp. 10.5 mm.; 0.42 inch. 



Hab. — Maryland (Plunimer'.s Island). 



A female speciman, collected by Mr. A. Busck, in the U. S. Nat. 

 Mils. A very distinct species. The labial palpi appear devoid of 

 seise. Veins 7 and 8 of forevving are stemmed. 



T. marmorella Ch.— Dyar's List, p. 572, No. 6512. — "Head and palpi 

 yellowish white; the second joint of the palpi brown on the outer surface. 

 Thorax and forewings white, marbled with dark brown spots which are confluent, 

 the basal fifths being white, except a brown spot on the base of the costa, one on 

 the base of the dorsal margin, one on the fold and one between it and the dorsal 

 margin ; in the remainder of the wing the brown prevails; one of these brown 

 spots is on the costa before the middle and reaches the fold and another about 

 the middle of the costa does not quite reach the fold, and behind it along the 

 apex is a row of distinct and separate dark brown spots, five of which are on the 

 costal margin. There is a dark brown hinder marginal line extending through 

 the middle of the dorsal cilia, and the cilia behind it are dusted with black. 

 Al. ex. three-sixteenths inch." 



The above is Mr. Chambers' description, to which I have nothing 

 to add. Four specimens in my collection, all in poor condition, I 

 refer with some hesitation to this species. There is a specimen 

 in the U. S. Mns. collection, which, however, I have not seen. Mr. 

 Busck writes me that it is a broad winged species.

 "Gray, flecked and spotted with fuscous, which in some lights appears reddish 

 or brownish golden ; one of the spots is at the base of the costa. and opposite to 

 it on the dorsal margin is a smaller one connected with it by scattered fuscous
