by Boisduval as inliabitants of that island — namely, Callidryas 
florella (Fab.), C. rhadia (Boisd.), Terias rahel (Fab.), Janonia 
rhadama (Boisd.), and a new species? of Lihytheay thus rais- 
ing the number of known Mauritian species to 25, or 26 inclu- 
ding Thymele [Ismene) ramanatek (Boisd.). Upon the habits &c. 
of these species the author gives some details. Of the 26 species, 
18 occur in Bourbon, 19 in Madagascar, and 18 on the African 
continent ; 8 are also found in Asia, 5 in Europe, 3 in Australia, 
and 2 in America. The only endemic species are Papilio phor- 
banta and P. marchaln. The Asiatic species are nearly cosmo- 
polite, and this applies still more strictly to those occurring in 
other parts of the world. Euplcea euplione of Mauritius and Ma- 
dagascar and E. goudotii of Bourbon are the only indications 
of Asiatic alliances in the Mascarene group ; the latter occurs 
also in Natal, and the former is said to inhabit Zanzibar. Bour- 
bon appears to possess at least two peculiar species of Butterflies, 
Papilio disparilis Neptis dumetorum) Lyccenamylica [G^vlqw.) 
is unknown to the author. 
Birchall (Ent. M. Mag. iii. pp. 5-6) gives the number of known species of 
Irish Butterflies at 43, leaving 21 of the British species unrepresented. Of 
these, 16 are also absent from Scotland ; and Birchall suggests that this may 
be accounted for by the supposition that the separation of Ireland from 
England took place previously to the introduction of the bulk of the present 
fauna, whilst a connexion was still maintained with Scotland ; this he thinks 
may explain the northern character of the Irish fauna. 
Reakirt (Proc. Ent. Soc. Phil. vi. pp. 122-123) remarks upon the relations 
of the Rhopalocera of the Colorado district with those of other parts of 
America. The closest affinity is with California, 23 species out of 72 being 
common to the two districts j the number common to the Colorado Territory 
and the whole of the Eastern States is only 21. The number of species 
peculiar to the Rocky Mountains is 26. 
Behr publishes a catalogue of the Rhopalocera of California (Stett. ent. 
Zeit. 1866, pp. 213-216). 
Felder publishes 4 plates ('44-47), of which the text is still wanting j they 
contain flgures of species of the following genera : — Napeogenes 2, Athyrtis 1, 
Ithomia 9, Ceratinia 1, Oleria 1, Ilymenitis 1, Mechanitis 1, Melincea 2, 
Acrcsa 7, Eueides 2, Helicmms 6. 
Muller cites two instances of hermaphrodites recorded by Nickerl and 
not referred to by Hagen. The species are Satyrus semele (Linn.) and Lyccena 
argus (Linn.). Ent. M. Mag. iii. p. 114. 
Papilionides. 
Reakirt (Proc. Acad. Nat. Sci. Phil. 1866, pp. 341-342) gives the fol- 
lowing synonymic indications with regard to species of Papilionides described 
chiefly by himself but previously characterized by Felder : — Atrophaneura 
erytlirosoma (Reak.) = P. semperi (Feld.j ; P.palinurus (Ji.^=^d<sdalus (F.) ; 
P, varasi (R.) =: hystaspes (F.) ; P. harsjieldii (R.)=/ec?c6owna (Esch.) j P. 
eurypylus {R.')—gordion (F.); P. moorei (R.^zzieuphrates (F.) ; Leptocircus
