of continental America. Of the Nymplialina (H.-Sch.) we 
find 36 species, belonging to 27 genera ; Argyhms, Br^nthis, 
Grapta, Viahessay and Limenitis are unrepresented. The Liby- 
theina have but one representative, and the Erycinina are 
wholly deficient. The Lyesenina also are very poorly repre- 
sented by 12 species, four of which belong to Lyc(ena and seven 
to Theda. Of the Pieridina Herrich- Schaffer records 31 
species, 16 of which belong to Terias and eight to Callidryas. 
Of the Equitina (H.-Sch.) 11 species of Papilio are recorded; 
Weidemeyer catalogues 79 species of that genus from North and 
Central America. The Hesperidina are commenced ; the spe- 
cies are said to be numerous, and many of them new. Remarks 
on the characters and synonymy of many of the species are ap- 
pended to their names. 
Trimen has described the general characters of the Rhopalo- 
cera of Madagascar. The total number of known species of 
Butterflies inhabiting. that island is stated by him at 73, belong- 
ing to 34 genera and 11 families. All these families are repre- 
sented in Africa. The Ageronidcey HeViconideRy Brassoltdaey and 
Morphida are wanting in Madagascar and also on the African 
continent. Not one of the genera is peculiar to the island, and 
of the 73 species ^5 occur elsewhere; and 39 of these are inha- 
bitants of Africa (27 exclusively) . The number of species com- 
mon to Madagascar and the Mascarene islands is 15 ; but the 
latter contain eight species not yet found in the gr eat island, two 
of which, however, occur in continental Africa. The number oc- 
curring both in Madagascar and Asia is 12, but 11 of these are 
also inhabitants of Africa. Thus the conditions presented by 
the Rhopalocerous Lepidoptera are in striking contrast to those 
indicated by Sclater as presented by the Mammalia, beitig in 
strict accordance with what might have been expected from the 
geographical position of the island. 
Weidemeyer has published in the ^Proceedings of the Ento- 
mological Society of Philadelphia’ a "Catalogue of North- 
American Butterflies,” now reprinted in a separate form. The 
arrangement is that of Doubleday and Westwood’s ^Genera of 
Diurnal Lepidoptera;’ and the genera of which no species occur 
in North America are inserted in their proper places, with a note 
that they are unrepresented. The author has, however, adopted 
a plan which diminishes the value of his work, by almost entirely 
ignoring the works of Linne and Fabricius, on the ground that 
recent discoveries have rendered their descriptions "unreliable 
and of little value”; accordingly w^e find the species named by 
those authors attributed to the first writer who has given re- 
cognizable descriptions or figures of them. The synonymy of 
the species ' is reduced to the smallest possible compass, but 
some useful remarks on the species are appended to each family.
