search I collected about 20 larvae, mostly full-grown. For these I 
prepared a fitting habitation by cutting off a piece from the lowermost 
part of the plants above the first knot, and planting them with one or 
two roots in a preserving bottle in moist earth. I then placed my 
larva? on the open ends of the stems, and had the pleasure of seeing 
them quickly make a way through the shoot which closed the lower- 
most joint of the stem, and the opening thus made, they afterwards 
fastened up with some silk. I now placed my bottles in a cool place, 
and left them undisturbed for about three weeks. 
At the expiration of that time I examined my nursery, and found 
that most of the larva? had changed to pupa? ; some were in their 
cocoons still unchanged, whilst two or three, which had been the 
smallest specimens, were now about full-grown, and still feeding. One 
of these I separated in order to describe it. 
On -examining the cocoons and pupa?, which were mostly in the 
stems, I found, not without some surprise, that they completely resem- 
bled those of Depressaria nervosa, which I had placed in sej)arate 
bottles, and which in the mean time had also changed, only they were 
rather smaller ; so that I came to the conclusion that the new larva 
was also a Depressaria larva, since the pupse of that genus show a great 
similarity by which they may be immediately recognised. I had anti- 
cipated something else. 
In consequence of this similarity, I now carefully collected the 
pupa? of the new species, put them on dry sand in a separate vessel, 
and the larva which I had set aside for description, after carefully 
describing it, I again supplied with fresh food, in order to bring it to 
its change, which actually happened. Although I had imagined to 
myself distinctly the difference there ought to be between the images 
of the new larvae (which I now suspected to be that of Depressaria 
Teatiana) and JD. nervosa, I kept, nevertheless, the pupa from the 
described larva separate, because I conceived the possibility that in the 
stems which I had given to my new larvae, and which naturally I had 
not opened, pupae of spun-up larva? of nervosa might occur ; for this 
cannot be ascertained from the outside, as the larvae often close up 
very adroitly the holes which they make in order to get inside the 
stem, either beneath a knot or elsewhere. 
That I was not mistaken in this hypothesis of a mixture with 
nervosa was, as I imagined, evident to me, when, after some of my 
pupa? of nervosa had come out in my box, a moth appeared in the cage 
in which I kept my new species, which I also took for only a rather 
smaller, poor specimen of nervosa. To my great astonishment, how-
