necessary in attempts to collect them. The full-fed larvae de- 

 scend to the ground and change to pupae among the fallen 

 leaves. The perfect insects have the peculiarity of sliding 

 about when laid on their backs. D. atrodorseUa Clem, is yel- 

 low ochreous, with six or eight black costal dots, with a red- 

 dish patch extending from the disc towards the tip of the wing. 

 The head is rufous above, with the face blackish brown above 

 and yellowish beneath. 



During the last summer we observed a locust tree which had 

 some of the branches well nigh defoliated b}' an imdescribed 

 species of this genus which we may call the Depressaria rob in - 

 iella (Plate 8, fig. 14, natural size). The head, palpi and fore 

 wings are light brick red, spotted irregularly with yellow, and 

 the antennas are slate brown. The fore wings are a little 

 darker in the middle, especially towards the inner edge. There 

 is a submarginal darker brown band near the outer edge, which 

 does not reach the costa, and on the outer edge is a row of 

 minute black dots. The hind wings and abdomen are of a pale 

 slate gray, and of the same color beneath, while the legs are 

 of a very pale straw yellow. It differs from most of the spe- 

 cies of the genus in having the apex of the fore wing less 

 rounded than usual, and in this and other respects it is allied 

 to the European D. laterella. The larva is thick-bodied, with 

 a black head, and is green, the cervical shield being green. It 

 devours the leaves, drawing them together by threads, and 

 also eats the flower buds. It was most abundant in the last 

 week of June. It turned to a chrysalis July 8th, and in about 

 two weeks the moth appeared. 



In Gelecliia the fore wings are rather long and pointed, and 

 the hind wings are trapezoidal and more or less excavated below 

 the tip. The terminal joint of the labial palpi is slender, al- 

 most needle-like, smooth and pointed. This genus is of great 

 extent and comprises a considerable diversity of species. The 

 moth is extremely active. Clemens states that "the habits of 

 the larvae are extremely varied, feeding upon leaves, flower- 

 buds, young shoots, and in the interior of grain and seeds. The 

 species that feed in buds and shoots are mostly in the larva 

 state in spring and the beginning of summer ; those that feed 

 in and upon leaves are met with in summer and autumn, and
