300 AMERICAN MICRO- LEP1DOPTERA. 



Apical spot triangular and dark brown; cilia silvery fuscous; hindwings and 

 cilia a little darker than the cilia of the forewiugs. Abdomen shining bluish 

 black on its upper surface. Alar expanse less than one-third inch. Spanish Bar. 

 The larva is cylindrical, and makes a large tentiform mine on the under surface 

 of the leaves of an Alnus." 



The above is Chambers' description. This species is apparently 

 close to alnicolella Wlsm., the principal difference being in the lar- 

 val habits, as noted by Lord Walsingham, under his description of 

 alnicolella. I have seen no specimen and no type is in existence. 



Lithocolletis malimalifoliella Braun.

 Lithocolletis malimalifoliella Braun, Ent. News, xix, 101, 1908. 



Antennae gray. Palpi silvery white. Face silvery white. Tuft golden brown, 

 tipped with dark brown. 



Thorax and forewings golden brown. There are three longitudinal stripes on 

 the thorax, one median, the other two passing over the patagia and continuous 

 with a median white basal streak, ending at one-third the wing length and dark 

 margined above and around the tip behind. The dorsal margin is also white for 

 a short distance. There are three costal and two dorsal white streaks of which the 

 dorsal are the larger, all dark margined before, and the first pair dark margined 

 at the tip behind. The first costal at the basal third is small, oblique. The first 

 dorsal at the basal fourth is very large, oblique and curved, ending just before 

 the apex of the first costal. The second costal streak is small, nearly perpendic- 

 ular, and opposite the second dorsal, which is triangular, and placed just before 

 the tornus. The third costal streak, at the same distance from the second as the 

 latter is from the first, is somewhat oblique, pointing forward. A third dorsal 

 streak is indicated by the dark margin. An elongate black apical spot, witb a 

 few scattered brown scales before it. Marginal line in the cilia blackish with a 

 distinct blue lustre around the apex. Cilia gray, brownish around the apex. 

 Alar expanse 5.5-6 mm. 



Hindwings dark gray. Cilia gray. Abdomen very dark gray above, silvery 

 white beneath. Legs gray, hind tarsi blackish, grayish at their bases. 



I have bred this species from small tentiform mines on the under- 

 side of leaves of apple, Mains Mains (L.) Britton. The appearance 

 of the mine is entirely different from that of L. cratcegella Clem. 

 The mine is much wrinkled, and the leaf is strongly folded. The 

 parenchyma is eaten in spots, giving the leaf a speckled appearance 

 on the upperside. The pupa is suspended in a few silken threads. 

 I also have flown specimens from Montclair, N. J., which are identi- 

 cal with the bred specimens. 



There are two specimens of this species in the Museum of Com- 

 parative Zoology at Cambridge, Mass., bred by Chambers on quince, 

 in Kentucky.
