CHAMBERS ON NEW TINEINA. 101 



the marginal streaks are the same — three dorsal and four eostal, the third 

 dorsal minute, the second large, and the first very large, and the first 

 costal very oblique. In this species, however, these marginal streaks 

 are dark-margined on both sides, while in cratccgella it is only the first 

 costal and first and second dorsal that are so margined, the others only 

 dark margined before. Apical spot circular, and hinder marginal line, 

 as in cratcegclla, at the base of the cilia. 



The hind wings and cilia dark lead-brown — darker than in cratcegella. 

 Abdomen fuscous, a little paler beneath, and tuft yellow. Legs and 

 tarsi white, marked on the anterior surfaces with brown. Kentucky, 

 early in May. 



L. populiella, n. sp. 



1 have bred a few species from small tentiform mines on the under 

 side of leaves of the Silver-leaf Poplar, which, though very distinct from 

 argent inotella Clem, and L. Jitchella Clem., I place in the same group 

 with them. It is perhaps nearer to L. carpinicolclla than to any of the 

 other species figured in the Nat. Hist. Tin. 



Palpi, head, tuft, antenna}, under surface of thorax, legs, and abdo- 

 men pure snowy-white; upper surface of abdomen and fore wings pale 

 golden : there are three white longitudinal streaks on the thorax (oue 

 median, aud continuous with a dorso-basal white streak ou the wings, 

 the other two passing over the tegute* aud continuous with a median 

 basal white streak on the wings); there is also a costo basal white streak 

 on the fore wings, and these three basal wing-streaks are of about equal 

 length, and less than one-fourth of the length of the wings. Immedi- 

 ately behind the dorso-basal streak, and scarcely distinct from it (prob- 

 ably sometimes confluent with it), is the first dorsal streak, which 

 approaches a square form, and is dark-margined before and above. 

 Almost opposite to this dorsal streak, but a little behind it, is the first 

 costal streak ; it is oblique, not poiuted, and is dark-margined before. 

 The second costal and second dorsal are opposite each other, the costal 

 one being the largest of the two, triangular and dark-margined before. 

 The third costal and third dorsal are nearly opposite, the costal being 

 perhaps a little farther back, and being larger than the dorsal, and 

 larger also than the second costal ; both are dark-margined before. 

 These are only the three dorsal streaks. The fourth costal is just be- 

 fore the apex, points a little obliquely forward, and is margined behind 

 by a small apical patch of brown dusting. Cilia white, with a brownish 

 hinder marginal line at their base. Alar expansion one- fourth of an inch. 

 Ohio aud Kentucky. 



L. BIFASCIELLA, W. sp. 



Tongue, palpi, and face silvery-white, the outer surface of the third 

 joint of the palpi brown toward the tip, and the forehead tinged with 

 'Following Buruieister, I have sometimes called these organs " patagia".
