Scelorthus pisoniella Busck. This little larva, living on the 

 backs of the leaves of Pisonia obtusata has already been des 

 cribed (Journ. N. Y. Ent. Soc., VIII, 240, 1901). 



Lamprolophus lithella Busck. The larva bores in the young 

 stems of Pisonia aculeata. I have described it. (Journ. N. Y. 

 Ent. Soc., VIII, 241, 1901.) 



Cycloplasis panicifolieUa Clemens. Dr. Clemens has de 

 scribed the mine. The larvae occurred commonly on Panicum 

 divaricatum in January, several together in the same leaf, the 

 mines forming a lot of parallel lines directly towards the apex. 

 When enlarged into blotches, frequently several are confluent 

 and the larvae in a common mine. At maturity the circular 

 pieces of the epidermis, 3.2 mm. in diameter, are cut out, folded 

 in the middle and used as cocoons. 



Head very flat, the clypeus high, touching the vertical triangle ; pale 

 luteous, sutures and mouth brown, a black and a brownish ocellus; half 

 retracted in joint 2. Body translucent, whitish, the dorsum very flat, the 

 venter much more rounded; segments moderately moniliform ; joints 2 

 and 3 large, 4 a little smaller, 5 to 13 about alike, 13 a little smaller, 

 divided. No feet. A large, rounded, black shield on the venter of joint 

 2. Setae obsolete ; no tubercles. 



Nepticula condaliafoliella Busck. The mine is formed on 

 the upper side of the leaves of Condalia ferrea. Linear, gradu 

 ally widening, starting from the margin, much convoluted and 

 directed finally toward the center. The mine is short, compactly 

 folded ; the frass forms a central black line. 



Larva green, moniliform, with band-shaped clypeus. Thoracic 

 feet on joints 3 and 4, abdominal ones on 6 to 1 1 ; joint 13 bul 

 bous truncate, small, no feet. A black patch within behind the 

 head. 



Nepticula myricafoliella Busck. The larvae form mines on 

 the upper side of the leaves of Myrica cerifera. The mine starts 

 at the midrib or elsewhere on the leaf, gradually widening, 

 usually contorted, but rarely quite straight. 



Nepticula sp. A single specimen at light. 



Leucoptera erythrinella Busck. The larvas are leaf miners 

 on the upper side of Erythrina herbacea, very common, fre 

 quently causing serious injury to the plants, many mines in nearly 

 every leaf. The mine is narrow, but soon widening to a mode 

 rate blotch ; finally visible below, the leaf being killed through. 

 The larva escapes by a hole in the mine above. Somewhat flat 

 tened, the segments moniliform ; joints 2 and 3 wide, 4 narrow, 

 5 to 10 a little wider and about equal, n and 12 successively 

 smaller, 13 elongate, narrow. Colorless, greenish, the food dark
