84 ENTOMOLOGICAL NEWS. [Feb., 'l6 



dorsal spot with its apex projecting a little beyond the corresponding 

 but smaller costal spot; second pair of spots curved and almost meet- 

 ing. A dark brown irregular apical spot, preceded and encroached upon 

 by a streak of white scales. Cilia golden, gray toward the tornus ; ter- 

 minal line of scales dark brown. 



Hind wings gray, tinged with red. Legs dark brown, spurs and ter- 

 minal segments of tarsi whitish or silvery. Abdomen dark brown, 

 whitish or silvery beneath. 



Expanse: 5 mm. (male) ; 7 mm. (female). 



The mines on Gaylussacia were collected at Lancaster, Ohio, 

 August 21 ; those on Oxydendrum at Sugar Grove (about sev- 

 en miles distant) and southward, August 20. The mine is of 

 the usual tentif orm type on the lower side of the leaf ; except 

 for an occasional patch in the center, the leaf substance in the 

 mined area is entirely consumed. One-half of the mine is par- 

 titioned off to form a pupal chamber. 



Lithocolletis picturatella n. sp. 



Palpi whitish, dark on the sides ; face and tuft reddish ocherous, the 

 latter with some whitish scales; antennae dark brown above with paler 

 bands. 



Thorax and fore-wings brownish ocherous. There are four costal and 

 three dorsal white spots, the second pair uniting to form an outwardly 

 angulated fascia; all are dark margined externally. Of the first pair 

 of streaks, the dorsal is the longer and in some specimens almost meets 

 the costal streak; it is parallel to the dorsal arm of the fascia. The 

 external dark margin of the fascia is continued outwardly at the angle, 

 usually as a dark shade, rather than as dusting; this dark shade some- 

 times extends between the third pair of spots almost to the apex. Third 

 pair of spots small and opposite. Scattered dusting in the apex is pre- 

 ceded by a small curved costal streak. 



Hind wings and cilia gray, brownish tinged. Fore-legs almost black 

 on the upper surface, tarsi white, conspicuously spotted with black 

 above; middle and hind legs ocherous, with some darker shading, tarsi 

 white, with black spots near the ends of the segments above. 



Expanse: 6.5-7. mm. 



Described from eighteen specimens bred from mines on bay- 

 berry, Myrica carolinensis Mill, collected in July at East River, 

 Connecticut, by Dr. Chas. R. Ely. Mines of this species have 

 been found in a number of other localities in New Jersey and 

 New York where the food plant occurs. 



Types in Dr. Ely's collection, the United States National 

 Museum, and in my collection. 



The mine is a brownish blotch on the upper side of the leaf. 

 At the tune of pupation, a single prominent ridge extends 

 across the mine. 



The nearest relative of this species is L. bcthunclla Oiam., 

 from which it can be most easily distinguished by the conspicu- 

 ous black spots on the upper side of the white tarsi.
