over the apical part of the wing, and the extreme apex is dark fuscous. Hind 

 wings silvery fuscous, darkest along costa and toward the tip; cilia yellowish. Abdo- 

 men dark silvery fuscous; legs whitish, shaded with dark fuscous. 



Alar expanse 11.5 to 14 mm. 



Habitat. — California. 



Food j)lant. — Applopappus plnifoUus. 



Type.—^o. 6288, U.S.N.M. 



Described from many specimens bred by Mr. D. W. Coquillet and Mr. A. Koebele, 

 from thin-walled oblong galls, formed by the undeveloped bud of Applopappus pini- 

 foUu.'i near Los Angeles, California. 



ANACAMPSIS INNOCUELLA Zeller. 



Larva. — Head rounded, flatly outstretched, vertex under joint 2; 

 black or brown with black sutures. Body normal, scarcely flattened, 

 a little smaller at the ends. Cervical shield slightly rugose, brown 

 and black behind and at the sides, shading to whitish before. Skin 

 transparent, appearing white from the fat, food obscurely green; 

 dorsal vessel dark. Tubercules moderate, rounded, black, ia+ib, 

 iia+iib, iv+v. Thoracic feet black; abdominal ones normal, short; 

 no anal plate. 



The larvae occurred as leaf rollers on the broad-leaved cottonwood 

 {Populus fremontii wislezeni) at Denver, The leaf is neatly rolled to 

 several turns, forming a remote spiral, held with cross bands of silk 

 throughout. The end is open, and the larva can be seen in the center. 

 Sometimes several leaves are involved. 



NEALYDA BIFIDELLA Dietz. 



Larva. — Head small, flat, clypeus rounded triangular, reaching the 

 broad, membraneous, vertical triangle, mouth small; pale luteous, 

 sutures of clypeus brown, ocelli small, black. Body moderate, flat- 

 tened, joint 2 smaller than 8, 4 and 5 equal, then slightly enlarged 

 to the middle of abdomen and a little tapering to end. Segments 

 angularly projecting laterally posteriorly; joint 13 small, divided, the 

 posterior half abruptly smaller. When retracted the segments are 

 flattened moniliform. Thoracic feet small, slender, wide apart; 

 abdominal ones on joints 7 to 10 like slender papillae, with a spoon- 

 shaped enlargement at tip, in shape much like the thoracic feet, 

 without hooks; no feet on joint 13. Translucent pale yellow, whitish 

 pedal ly; joint 2 dor.sally and ventrally shagreened; no shields. Setaj 

 iv and v distinct, remote, in line, v smaller and just below the spiracle, 

 iv posterior; vi rather distinct, but dor.sal setpe obsolete. 



Living in blotch mines under the upper epidermis of the leaves of 

 Allionia nyctaglnea., the mine near!}- reaching through to the under 

 surface; small for the size of the larva, the frass gathered in a bunch 

 at the end. Found at Salida July 25; moth August 8.
