whether happy (as all students should be) or not, must adopt a trinomial nomencla- 

 ture. Will the reviewers consider for what that trinomial nomenclature must be 

 adopted ? They seem to have missed the essence of my scheme, which is to 

 pi-actically separate the nomenclature of tlie species fi'om that of the genus. As I 

 am sure that they wished to do justice to my ideas, and as they stated that " the 

 " foregoing sketch gives a correct view of what appears to bo the aim of our author, 

 I have thought it worth while to ask the insertion of this short note. — D. ShAEP,

 reply to our Review, as we really wish to do justice to the author's ideas ; and we

LepIDOPTEEA, RnOPALOCEEES AND HeTEROCEEES, INDIGENOUS AND ExOTIC, 



with descriptions and coloured illustrations ; by Herman Steeckeb. Parts 1 — 6, 

 4to, each with one coloured plate. Reading, Pennsylvania ; 1872 — 73. 



Among the numerous and beautiful new works on Lepidoptera which we are 

 constantly receiving fi'om America, the present deserves special notice for its compre- 

 hensive character. It is not confined to any one group of Lepidoptera, nor even 

 intended to be confined to tliose of the United States, though hitherto it has con- 

 tained only new, rare, or unfigured North American species. 



Three of the six parts before us contain butterflies ; two more, moths of the 

 gemis Catocala (a specially favourite genus with Mr. Strecker, who intends in time 

 to figure all the species) ; and another, a fine new Platysamia allied to the well- 

 known P. Cecropia. Part 7, which has not yet reached us, will be devoted to the 

 genus Smerintkus. Each part contains one plate, crowded with good figures (some- 

 times as many as fifteen) ; and, although issued at a very low price, the enterprising 

 author proposes to give two plates instead of one, as soon as the number of subscri- 

 bers will permit.

Fe'lix idouard Guerin-Meneville died at Paris on the 2Gth of January last ; 

 he was in bis 75th year, having been born at Toulon in 1799. From the days of his 

 early manhood he was a constant writer on various branches of entomology, and in 

 1861 the number of works or articles from his pen had already reached 320, according 

 to the ' Bibliotheca Entomologica,' and these are distributed over almost all orders 

 of insects. For very many years his attention was mainly devoted to descriptive 

 and systematic entomology, but latterly the economic brancli of the subject occupied 

 most of his time, especially sericiculture and the formidable vine-pest Phylloxera, 

 and in these he received fresh impulse by the establishment of the French Acclima- 

 tisation Society, in the affairs of which he took a leading part. Although in this 

 country sericiculture may probably be looked upon as an experimental pastime, it 

 is far different in France. The threatened (and in part effected) ruin of the French 

 silk-growers by the notorious silk-worm disease, was naturally brought prominently 

 imder the notice of G-uerin-Me'nevillc, and his investigations did much towards 

 throwing light upon the obscure and remole causes of the disease; latterly, the
