144 THE ENTOMOLOGIST. 



sluggish habits as an insect in the perfect state. Whilst eating and 

 growing during autumn the larvae live within the stems and root 

 of the plant, eating the pith. When the plants begin to decompose, 

 the interior of the stems in which the larvte are living become 

 vessels full of water. This distressed me much, as I feared the 

 larvffi would be drowned, but they seem rather to enjoy it. As 

 the liquid dries up they are equally at home and comfortable for 

 the next four months within the dry stems, laying dormant until 

 the warmth of spring calls them to complete their metamorphosis.

Entomological Nomenclature. — I must say I protest 

 against the useless and unscientific method of giving person's 

 names to species ; and I quite agree with Mr. C. A. Briggs when 

 he says that if such names are occasionally given they should 

 only be taken from leading or very energetic entomologists 

 deserving such a reward, for as such it ought to be given, and 

 then only to those who recognise the great honour conferred 

 upon them. — E. A. Brunetti ; 15, Lower Grosvenor Place. 



NOTICE OF NEW BOOK. 

 The Butterflies of Europe. Illustrated and described by Henry 

 Charles Lang, M.D., F.L.S., &c. London : L. Reeve & Co. 

 We have received a specimen plate and circular of this 

 promising work. The plates will be prepared by Messrs. West, 

 Newman & Co., and those already produced are an example of the 

 very fine colour-printing of Natural History subjects executed by 

 that firm. It is evident this will become the standard work upon 

 the subject, and, being issued in parts, it will be within the reach 

 of every entomologist. Each monthly part wifl contain four 

 coloured plates, and sixteen pages of letterpress. It is intended 

 to represent both upper and under sides, where necessary, of the 

 butterflies, as well as the more important named varieties, and 

 larvae, &c., when possible. It is estimated that the work will be 

 complete in twenty parts, which are charged 3s. Q>cl. each part. 

 We hope the work will command the circulation it deserves, and 

 that it will give an impetus amongst English entomologists to the 

 study of insects other than those inhabiting these islands. — Ed. 



Erratum. — In our last number, p. 115, line K! from foot, /or 

 "Attacus luna" read "Attacus Selene."
