at the same time. The large-leaved sallow (Sali.x caprea) must be 

 examined now, for the topmost shoots nourish the bright-green larvae 

 of P. capveana, and in the shoots of Scotch fir the larva of R. huoUnaua 

 is also to be found in plenty. 



In the shady parts of the wood, the JieXony (St achy s hetoiiicaj, 

 which is now growing freely, soon makes us pause to examine the 

 blotches on some of the leaves, and there, sure enough, is the long 

 cases slightly curved at the end, of the larva of C. Wockeella. On the 

 Broom the larva C. saturatella in their short stumpy looking cases are 

 now getting full grown, while under the bark, the larva of Cemiostoma 

 spartifoUella are still making their long narrow mines, but which they 

 will now soon quit, to spin their white cocoons in the buds or angles 

 of the twigs. In the damp shady parts of the wood where the 

 Epilobmm angustifolhwi is growing freely, we shall now find the larva of 

 Lavevna contuvhatella in the drawn together tops. We will now retrace 

 our steps, examining the elms in hedges, and taking a supply of the 

 large flat serrated cases of the larva of C. limosipennelln , and the short 

 smooth cases of C. hadiipeunclla which are are found on tlie same 

 trees, and in the shoots of hohy the larva of (jvap. lucvaua can now be 

 had commonly. 



By the above, which is only a portion of what can be done this 

 month, it will be seen there is plenty to do, never forgetting that our 

 main object is to work out the life history of those larva as yet 

 unknown, and doing all we can towards that object, for as time goes 

 on, we become more and more impressed with how little we know, and 

 what a deal there is yet to learn. — Geo. Elisha, Shepherdess Walk,
