264 Miscellaneous. 



destroy the insect to obtain the silk, as is necessary in the case of 

 the mulberry silkworm. The Eri silkworm is a much larger insect, 

 and belongs, not to the family Bombycida3, like the mulberry silk- 

 worm, Bomhyx mori, but to the Saturniidte, or Emperor Moths (one 

 species of which is found in Britain), and is not very distantly 

 allied to Attacus atla^, the largest known moth, which, like the Eri, 

 is also an Indian species. 



The present monograph gives us the full history of the Eri silk- 

 moth in all its stages, illustrated, with elaborate instructions for 

 rearing and for preparing the silk. It concludes with chapters on 

 the castor-oil plant and on the Eri silk industry. We may add 

 that the Eri silkmoth is very closely allied to the Ailanihus silk- 

 moth, the cultivation of which Dr. Alexander Wallace attempted to 

 introduce into England some years ago, with a moderate amount of 

 success. W. F. K".

It was at first contemplated publishing the third and concluding 

 part dealing with species of the Peltatinse in the summer of this 

 year. This has been found impossible, owing to insufiicient data 

 relating to two species — corneus and jpoeppigi — and the doubtful 

 identification of the shells of species dissected ; this could not be 

 settled until the types of these species had been seen. These are 

 fortunately in the museum at Stettin. Dr. Heinrich Dohrn, to 

 whom I recently wrote, has courteously promised assistance, but, 

 owing to the collections in his charge being packed up pending 

 transfer to new buildings, they cannot be got at until next winter. 



Besides this, further spirit-specimens of some species are wanted 

 from Natal ; these Mr. H. C. Burnup will endeavour to obtain, but 

 he tells me they cannot be secured until the right season comes 

 round, viz. midsummer, so that very little more can be done in this 

 family until we have entered on 1913.
