Rhopalocera. 
Newman has published (Ent. v. pp. 33-41) some remarks on 
the classification of butterflies. He proposes an arrangement 
founded on the condition of the pupa. lie doubts whether any 
real line can be drawn between the llhopalocera and Heterocera^ 
and ineludes Sijnemon and Urania in his arrangement. 
II. J. Slack (Stud. n. s. i. pp. 49-58) has been examining 
the structure of the scales of butterflies. They consist of an 
upper and a lower layer (not three layers), and in deposits of 
matter coming from one or both, and lying between the two. 
” The so-called ^ ribs ^ &c. of butterfly-scales seem to me only 
corrugations or wrinkles ; and the beads, more or less distinct 
or coalcscent, as the case may be, I take to be exudations in 
drops from the membranes, consolidating, so far as they do 
consolidate, in a definite form.^^ A plate is added, representing 
the scales of a few species. 
Kirby (P. L. S. x. pp. 494-503) has critically examined the 
synonymy of the principal genera of Diurnal Lepidoptera pub- 
lished from 1767 to 1816. The rules he proposes are based on 
the well-known rules of the British Association. 
A. G. Butler has published a ^Catalogue of Diurnal Lepi- 
doptera described by Fabricius in the collection of the British 
Museum,^ containing many valuable rectifications of synonymy, 
and the identification of many species previously unnoticed, or 
referred to genera at random by other authors. The original 
diagnosis (but not the description) is added to every Fabrician 
synonym.
