face of the leaf of the food plant, or other convenient neigh- 

 bouring objects. The pupa is not suspended by the tail as in 

 butterflies, but is supported on the cross-threads in a position 

 more or less horizontal. The head case of the pupa is nar- 

 rowly elongated and pointed, the process thus formed being 

 three-sided. It tapers regularly from the thorax to the 

 abdominal extremity, but on the back of the abdomen-case, 

 which is somewhat flattened, there are three ridges, one in 

 the middle, and one on each side. Colour blackish-brown ; 

 varied on the dorsum of the abdomen-case, with grayish along 

 the edges of the ridges, and with greenish between them. 



The first imago, taken in the pupa state on the 9th of 

 October, appeared on the 21st instant. The. imago rests in 

 the position of a Tischeria, that is, with the fore-legs applied 

 to the breast, the front part of the body elevated, and the ends 

 of the wings touching the surface on which the imago may 

 be standing. It is rather sluggish in its habits. The fall 

 brood doubtless hybernates until the following spring. 



The affinities of this little insect are very interesting. In 

 early life its mode of mining indicates a relationship to the 

 genus Nepticula. Its subsequent habits recall those of the 

 genera Tischeria and Butalis. 



The larva resembles the false loopers of the Noctuina, and 

 its mode of transformation closely approaches the pupation of 

 the Rhopalocerous larvae, the Pterophorina, and that of the 

 genus Elachista. In the imago the folded fore-legs, the 

 position at rest and the tufted front, show strong affinities 

 towards the genus Tischeria, and its wing structure places it 

 in the Lithocolletiform group of the Tineina, to which the 

 former genus belongs. 



The collector in searching for the larvae of this insect, 

 should look amongst the leaves that are most shaded, for 

 these are preferred to those exposed to the sun. After having 

 found a plant inhabited by them, he can either secure them 

 and rear them in breeding-vessels, or wait until the period of 

 pupation, and secure the pupae without the trouble of attend- 

 ing to the feeding of the larvae.
