56 INSECUTOR INSCITI^ MENSTRUUS 



shaded outwardly with dark purple, except at the base of the 

 terminal joint. Antennae dark brown annulate with whitish 

 at the joints of the segments. Fore wings and thorax dark 

 purplish, intermixed with straw-colored scales ; a costal tri- 

 angle similar in form to that of coroniella or gliitinella is faintly 

 discernible, with the help of a hand lens, the ground color 

 pale straw, but almost completely overlaid with dark purple. 

 Cilia gray, the apical cilia almost concolorous with the wings, 

 with two dark lines about the apex. Hind wings smoky gray 

 with paler cilia. Front and middle legs with nearly white 

 tarsi, marked at the tips of the segments with dark purple, 

 other joints dark purple, tibiae tufted ; hind legs straw color, 

 heavily shaded with dark scales outwardly, femora concolorous 

 with abdomen near coxal joint, the remaining portion shaded 

 with dark purple outwardly. Abdomen straw color, somewhat 

 shaded with dark scales above. Expanse, 13 mm. 



The larva in the late form has the following habits. A wind- 

 ing linear mine is first made, on the under side of a leaf, 

 ending in a small blotch which is generally near the edge of 

 the leaf. After leaving the mine it turns the edge of a leaf 

 downward, making a single elongated fold. Probably more 

 than one of these folds may be made by the same larva. When 

 nearly full grown it leaves this shelter and rolls the tip of a 

 leaf downward into a rather long cone, which is abandoned 

 when it is ready to spin its cocoon, which is of the usual 

 form. 



This insect is very near coroniella, from which it can be dis- 

 tinguished by its dark head and thorax and the darker ground 

 color of the wings. 



Gracilaria flavella, new species. 



Face pale yellowish. Labial and maxillary palpi pale yel- 

 lowish. Crown and thorax yellowish straw color with pur- 

 plish irridescence. Antennae yellow gray annulate with brown. 

 Fore wings a yellowish tan color bordered on the costa with 

 bright straw color. Cilia about the apex straw intermixed 

 with tan, elsewhere yellow gray. Hind wings and cilia yellow 

 gray. Abdomen yellow gray above, anal tuft and lower side
