NO.120S. NEW SPECIES OF TINEID MOTHS— BUSCK. 24l 



silveiy white, thorax with two longitudinal light golden j'^ellow .streak.s. 

 Forewings silvery white, on the apical half overlaid with light and 

 dark fuscous scales. These are arranged in irregular groups and 

 wavy lines, differing somewhat in different specimens, but generally 

 there is found a dark group at basal two-thirds just below costa, 

 which emits a dark streak inward and downward and two short ones 

 upward to costa. Besides these a transverse row of dark scales a little 

 nearer apex and a dark line parallel with the apical dorsal edge arc 

 rather constant in all specimens. Just before apex of the dorsal edge 

 is a small round black dot, and the narrow edge around the apex is 

 brown. In some specimens the fuscous scales are also sparsely suft'used 

 over the basal half of the wing, especially on the dorsal part, but in 

 most specimens this is pure white. 



From base of wing to apical edge are two longitudinal narrow lines 

 of light golden yellow, concolorous with the streaks on thorax. These 

 lines are obscured from the middle of the wing outward under the 

 fuscous scales, but reappear with a somewhat deeper golden color at 

 apex, where there are rather few dark scales; the upper line contains 

 the black apical spot. The earliest bred specimens were the most 

 white, with the fuscous scales light and limited to the apical half of 

 the wing; the later bred specimens were more suffused and more 

 darkly irrorate with the fuscous scales. Cilia yellowish gray at the 

 tip, with a dark line parallel with the dorsal edge. Hind wings and 

 cilia shining silvery white, abdomen yellowish, clothed with sparse 

 silvery white scales. The males sometimes displaved their sexual 

 organ, which was pointed downward and looked like the pappus on a 

 dandelion fruit, consisting of a stalk about 2 mm. long, on the end of 

 which was a globe of white hairs about 1 mm. long. Legs silvery 

 white, with ends of all points light fuscous. Front tibia rough-haired 

 at apex. Posterior tibia with heavy light fuscous tufts above and 

 below; beginning of tarsi with long fuscous hairs, especially above. 



Alar expanse, 8 to 10 mm. 



Described from more than 20 specimens, bred from Cliiococca race- 

 in osa^ collected by Dr. Dyar at Palm Beach, Florida. 



Type.—^o. -±951, U.S.N.M. 



Egg is laid on underside of leaf at the midrib. Mine begins as a 

 long, narrow, serpentine, and broadens out suddenly in a large irregu- 

 lar, whitish, half-transparent blotch, equally visible on Ijoth sides of 

 the leaf. The black frass is scattered irregularly. The larval charac- 

 ters are very strange. Up to its last larval molt it is slender, monili- 

 form with the tirst thoracic segment twice as broad as the head, from 

 thence gradually tapering backward. No trace of either thoracic 

 or abdominal feet. The head is flat, brown, the body white; first 

 thoracic segment with the large semilunar shield black; each of the 

 other segments with one dorsal and one ventral large shining black
