ANNETTE F. BRAUN. 293 



gined dorsal streak. A fourth white costal streak, just before the apex is also 

 internally dark margined. Between the first and second dorsal streaks is a 

 black streak in the fold. A third streak beyond the tornus is indicated by two 

 or three white scales. Black apical spot round or wedge-shaped. Marginal line 

 nt the base of the cilia blackish. Cilia silvery at the apex, tipped with gray. 

 Expanse 6-6.5 mm. 



Hiudwings and cilia dark gray. Abdomen dark gray. Legs gray. 



The larvse, which belong to the cylindrical group, form whitish 

 mines upon either the upper or the underside of leaves of locust, 

 Robinia pseudacacia L. A white silken cocoon is spun within the 

 mine. This species occurs throughout the Atlantic States.

Lithocolletis anronitens Frey and Boll, Stett. ent. Zeit., xxxiv, 216, 1873. Dyar, 

 Bull. 52, U. S. Nat. Mus., 1902, No. 6302. 



Head saffron brown, face lighter, antennae light brown, annulate with darker, 

 the apex whitish. 



Thorax and forewings shining saffron, rather light, legs yellowish gray, un- 

 spotted ; abdomen dark gray. The marks of the forewings have a strong me- 

 tallic lustre, which is between the color of gold and silver. There are four pair 

 of streaks. The first costal streak is at the basal fourth of the wing length and 

 is obliquely placed. The first dorsal streak is shorter, and nearer the base than 

 the costal streak. Almost in the middle of the wing, th re follow, placed one 

 directly above the other, two more marks, which are tall narrow triangles, some- 

 what dark margined internally, whose apices touch each other. The third pair 

 of markings at three-fourths of the wing length, are very similar to the preced- 

 ing pair, except that the dorsal triangle lies nearer to the base than the costal 

 .triangle. The fourth pair of markings, just before the apex of the wing, consists 

 of a small costal streak, which has inwardly a few dark scales, and a small dorsal 

 streak, which is placed so far back that it is beyond the hind angle. In the apex 

 is a black dot, toward the base overlaid with metallic scales. Cilia light; a dark 

 curved line extends through them at the apex. 



Hindwings and cilia gray. 



On the underside the forewings are dark brownish gray; the marks reappear 

 brownish white. 



The larvae live in fall toward the end of October on the underside of the leaves 

 of Alnus serrulata Willd. The mine is roundish, the loosened epidermis is much 

 wrinkled, resulting in the leaf being rather arched at this place. The imagoes 

 appear in May and June. 



The above is a translation of the original description. 



The type specimens were bred by Boll in Massachusetts. In the 

 U. S. Nat. Mus. is a specimen bred on alder, with no locality given. 



There is a very indistinct short basal streak on the wings. The 

 first costal streak is very long, oblique and curved, and dark mar-
