costal streak extending nearly to tornal cilia; the dorsal and costa 

 margins white from the beginnings of first dorsal and costal streaks 

 to base of wing; the inner sides of these white areas, as well as those- 

 of all costal and dorsal streaks, evenly dark margined; the first 

 costal and dorsal streaks also slightly dusted with dark scales on 

 outer margins; a conspicuous dark dot at apex; cilia golden 

 shading to yellowish wliite v/ith a median baud of dark smoky

Habitat. — Los Gatos, California (T. E. Snyder.) 



Food flant. — Platanus racemosa. 



A good series of moths reared under Hopk. U. S. No. 15187 from 

 tentiform mines on the under side of sycamore leaves. The larvae 

 were collected by Mr. T. E. Snyder, of the Bureau of Entomology^ 

 form trees along the river bank. His note states that the mines are 

 so numerous as to produce what amounts to defoliation of the trees. 

 Larvae collected June 12, 1917. Moths issued June 23 and 25 of the 

 same year. 



Type.—Csit. No. 21813, U.S.N.M. 



A very striking species, close to olivaeformis Braun, but easily 

 distinguished by its yellovvdsh head tuft, the narrower second dorsal 

 streak, and the evenly dark margined costal and dorsal dashes. 



Family TINEIDAE.

 Dorata inornatella Busck, Proc. Ent. Soc. Wash., vol. 6, p. 124, 1904. 



Several moths of this striking and interesting species were reared 

 (under Hopk. U. S. No. 12191) by the writer dm-ing 1915 from larvae 

 boring in the flower stems of Sotol, collected by Mr. Morris Chrisman 

 in Buehmen Canyon, Santa Catalina Mountains, Arizona. The 

 larvae, in superficial appearance and general shape, resemble the 

 Coleopterous round headed borers (Cerambycidae), but have all the 

 characters of typical Tineids. They form long galleries in the stems 

 of the plant and pupate in the galleries in silk-lined cells near the 

 base of the stems. The moths reared issued from early April until 

 late June. Inasmuch as nothing has been as yet recorded of the 

 early stages of this genus a full description of the larva and pupa is 

 here appended. 



General characters — larva. — (pi. 7, fig. 38; pi. 10, figs. 58, 59, 65, 66). 

 Cylindrical; stout, broadest at prothorax, tapering gradually to 

 pointed caudal end. Legs normal. Prolegs short and stout. 

 Crochets uniordinal in a long narrow ellipse. No anal fork. Pro- 

 thoracic shield broad, divided only by a faint line. No meso or
