-which looks like powdered sulphur. These cocoons should be looked for and destroyed 

 in the month of June. 



The final transformation of the insect is to the perfect state, that of the winged 

 moth. Fig. 43 represents the male ; the female is much similar but ^ 

 larger. The colour is a dull, reddish brown with paler oblique bars 1|| 

 across the fore-wings, as shown in the figure. The body is stout 

 and the whole creature very fluffy. They usually appear early in 

 July and may at once be recognized, as they are attracted into our 

 houses by lights at night, by the mad way in which they dash about 

 the room, here and there and everywhere, singeing their wings at 

 the Limp, then spinning on their heads on the table, and if it should be supper-time drop- 

 ping into the butter dish and covering its contents with the fluff off their bodies. These 

 idiotic performances may enable any one to identify them, and the opportunity should be 

 taken of destroying them, both for the purpose of getting rid of a present nuisance and of 

 a future generation.

The other insect referred to at the outset is called " The Forest Tent Caterpillar," 

 Clisiocampa sylvatica, Harris. It resembles the Apple-tree Tent Caterpillar very closely 

 in appearance at all its stages, and also to some extent in its habits. The eggs are laid 

 in clusters (Fig. 44 a) on the twigs of "trees as in the other species, but the mass is cut 

 square, as it were, at the ends instead of being rounded. The difference may be observed 

 by comparing the two figures, The individual eggs are of the shape shown at Fig iid ; 

 the top is depressed and circular, as at c.

The caterpillar is also very like that of the other species in colour and appearance, 

 but may be distinguished from it by the series of white spots along the back, which in the 

 Apple Caterpillar are united into a continuous line. Compare Figures 45 and 42 and the 

 difference will be plain at once. The moth (Fig. 446) resembles its congener in general 

 colour and appearance, but may be distinguished by its paler or more yellowish colour 

 and by the transverse bars on the wings being dark brown instead of white. 



Very much the same methods may be employed against this insect in all its stages, 

 as have been recommended for the other species. The most important difference in habit 

 is that the Forest Caterpillar spins a web against a bough or on the trunk of a tree instead 

 of a tent in a fork, and congregates at times on the outside of the web instead of beneath 

 it. When gathered together ki this way numbers may easily be destroyed by crush- 

 ing them wit h a stick or pole. These insects are very voracious feeders, and if let alone
