of the leaves on trees and bushes there are caterpillars 

 to feed upon them, and on some trees it is particularly 

 the case. So far in the season the majority of forms 

 have been comprised under few types, biit now fresh 

 ones will constantly appear. Hitherto two very dis- 

 similar larvae of Bomhyces and a number of those of 

 Noctuoe, which were pretty nearly alike in form to 

 a larva of the Geometra, are all we have seen. In colour 

 there were many variations, but the shapes have been 

 restricted ; now the trees and bushes, as well as low 

 plants, will constantly afford other forms, which will be 

 spoken of hereafter. 



The caterpillars of some Noctuce may be found during 

 this month in woods, craAvling on the trunks of trees at 

 night. Sometimes these are attracted by the syrup placed 

 to entice moths, and are found at it when the entomologist 

 goes with his lanthorn. 



The operations of April being now over, we come to 

 those of May. As the larvae on trees and bushes are as 

 yet very small, and in many instances not even hatched, 

 we will leave them to Nature, and say a few words about 

 internal feeders. These occur in many situations, and at 

 different seasons of the year ; and as we have not met with 

 many of the larger species we will speak of them for the 

 most part in general terms. First on the list is the Goat- 

 Moth (Cossus ligniperda), whose larva causes great damage 

 to various trees, amongst which may be mentioned the oak 

 and willow. These caterpillars are gi-egarious in their 

 habits, and feed upon the solid green M^ood, eating their 

 way, and forming in their line of march long galleries in 

 various directions. When the larvae are fiill-grown, the 

 gallery formed by each is large enough to admit the 

 thumb ; but it not unfrequently happens that specimens 

 of various sizes and ages occu.r in the same tree. They 

 feed for tAvo or three years ; and when a brood have left
