G. Dobfmeister (Mittheil. naturw. Ver. fur Steiermark, Heft ii. 1804, 
pp. ) has experimented upon the development of two forms of the 
genus Vanessa^ described ns distinct species under the names of F. yrorsa 
and V. levana. The latter appears in spring, after remaining in the pupa 
state about six months ; the former is a summer insect, the pupa state of 
which lasts only a few days. The occurrence of intermediate forms hashed 
some entomologists to believe that these Vanessce form only a single species ; 
and the author, by subjecting larvre and pupre to changes of temperature, has 
succeeded in producing a series of such forms, proving the identity of the two 
supposed species. In these and some other Lepidoptera ( Vanessa to and urticccy 
Euprepia caja) a low temperature seems to produce a darker or less lively 
coloration, and a high one to cause the colours to become more brilliant. 
The following known species are described and figured by Bremer (1. <?.): — 
Meliicea haicalcnsis (Brem.), p. 13, pi. 1. fig. 6 ; M. hritomartis (Asm.), var. 
plotina (Brem.), p. 14, pi. 3. fig. 2 ; M. arcesia (Brem.), p. 15, pi. 1. fig. 7 j 
Araschina hurejana (Brem.), p. 15, pi. 1. fig. 8 ; Neptis raddei (Brem.), p. 18, 
pi. 1. fig. 9. 
Argynnis diana. Notes on the sexual differences of this and other species 
of Argynnisj with explanatory remarks upon them in accordance with the 
Darwinian hypothesis, are published by Bates in Proc. Ent. Soc. Phil. vol. iv. 
pp. 204-207. 
Nowicki (Verh. zool.-bot. Ges. in Wien, xv. p. 176) describes a variety of 
Argymnts selene, 
Hcterochroa cclerio (Bates) = Papilio iphicla (Cram, nec Linn.) is figured by 
Bates, Journ. of Ent. ii. pi. 13*. fig. 4. 
Butler describes and figures Pomalceosoma medon (Lin.). Proc. Zool. Soc. 
1865, p. 672. fig. 6. 
Charaxcs. Butler has published (Proc. Zool. Soc. 1865, pp. 623-639) a 
synoptic list of the known species of this genus, founded chiefly upon those 
contained in the collections of the British Museum. The total number of 
species cited by him is 68 j C. rayi (Van der Hoev.) is said to be identical with 
the South American Megistanus hoeotus (Boisd.). Of the previously described 
species the synonymy is indicated ; the number of species described as new 
is nine. C. {Nymphalis^ baya (Moore) is figured, pi. 37. fig. 6. 
Papilla glance (Bates, Felder) is figured by Bates, 1. c. pi. 13 *. fig. 2. 
Tiimen states (Proc. Ent. Soc. 1865, p. 61) that Char axes argynnides 
(Westw.)= jalilusa (Trimen).
