In the larva Hate, this fpecies feeds on the leaves of the Rofe and 

 from that peculiarity it has received its figfiificant fpecifk name, 

 fofk. The larva caffs its fkin ieveral times before it becomes a pupa, 

 its exuviae we frequently find adhering to rofe-leaves. When the 

 larva is in its lafl fkin it is yellowifh, inclining to orange, with many 

 minute black fpecks, difpofed in ringlets, on every joint; but in the 

 early flages of its growth we find them of feveral fhades of colours, 

 between green and orange, and fome partake of both colours, and are 

 fpeckled with black, as in the laft fkin. The larva is very tender, 

 and, we fufpeft, is liable to fome diftemper of a very different 

 kind from any noticed to aflca other infefts; it then appears fickly, 

 and ^covered with a whitiih down, or powder, which flies off on 

 the fhghteft touch. We have often found the larva of another fpe. 

 ciesoi the fame genus covered with this kind of white powder, but 

 as they always d.ed, it is impoffible to determine to what infea they 

 belonged. ' 



In the pupa ftate, the outer cafe is no. perfeflly oval, but rather 

 flattened on the fides; it is generally faftened on a Halt, The pet-
