REPORT ON ZOOLOGY, MDCCCXLII : 
LEPIDOPTERA. 
Lefebvre (Ann. de le Soc. Ent. de Fr. xi. p. 5) has anew drawn atten- 
tion to the importance of exact observation of the nervures in the wings 
of Butterflies, and given many hints how their varieties are to be used 
in systematic division. He has considerably advanced our knowledge of 
this portion of their structure, as he has found out a sheath between the 
anterior and posterior nervures, viz., — a fold which stretches inwards from 
the outer margin to the middle cell. The treatise has also been abridged 
in the Rev. Zool, p. 52 : there are figures which illustrate it. 
Fischer Edl. von Rosslerstamm’s excellent work, “ Abbildungen zur 
Berichtigung und Erganzung der Schmetterlingskunde, besonders der 
Microlepidopterologie,” has, unfortunately, concluded 'with the twentieth 
number. On the other hand, Freyer’s “ Neue Beitrage zur Schmetter- 
lingskunde mit Abbildungen nach der Natur,” is happily progressing 
undisturbed. (The 58-68th numbers are before me for this report.) 
Hering continues his many valuable and copious contributions to the 
Lepidoptera of Pomerania (Ent. Zeit. p. 5). 
Many observations of diflerent collectors, on the Butterflies of Eng- 
land, are to be found in the Entomologist, p. 258, 260, 277, 283, 356, 
357, 358, 389, 393, 394, 396, 408) ; also Ann. Nat. Hist. x. p. 365. 
Rambur has begun his labours on the Lepidoptera, for his Fauna of 
Andalusia. I have not yet, however, received the number, and its ap- 
pearance is only known to me by the judgment pronounced upon it in 
Lefebvre’s treatise mentioned above. 
New Lepidoptera of West Russian Asia have been described by 
Eversmann (Bull, Mosc. p. 543). 
Harris has given an excellent view of the natural history of the most 
important Lepidoptera of North America (Ins. of Massachus.), including 
much that is new ; but which I hesitate to extract. It would be well 
if one of our entomological periodicals would give a comprehensive 
abridgement of the work. 
The Butterflies of Merian have been systematically arranged and illus- 
trated by Freyer; and are accompanied with remarks (Isis, p. 18, 327). 
Papilionid^. — Westwood has given a critical view of the African 
species of Papilio (Arcana Ent. i. p. 145, t. 37-40). There are figured : 
P. Ther Sander, F. (t. 38, f. 1, 2) ; Lalandei, God. (t. 37, f. 1, 2) ; 
cynorta, F. = ZeryntJiius, Boisd. (t. 40, f. 3, 4) ; Boisduvallianus, 
Westw., new species from Guinea (t. 40, f. 1, 2) ; trophonius, Westw. 
(t. 39, f. 1, 2) ; adamastor, Boisd. (t. 38, f. 3) ; agamedes, Westw. (t. 39, 
f. 3, t. 37, f. 3). This last is only a variety of adamastor, with which 
it is united by many intermediate forms. The author joins P. cenea, 
Stoll, (not Linn.) to the P. trophonius ; but at present I do not agree
