viz. M. Henri Deyrolle’s characters in eatenso of the genus Lissapterus, and 
these characters, I think, fully entitle the species to be raised to generic 
rank. I may also state that, although Prof. Westwood infers that the apterous 
condition of the insect had induced the generic separation, M. Henri Deyrolle 
does not even allude to this particular character in his definition of the 
genus.” 
Mr. W. F. Kirby communicated a continuation of his “ Synonymic Notes 
on Lepidoptera,” as under :— 
“In the present paper I have brought together various detached notes 
on synonymy, which will perhaps be more useful in the present form than 
scattered. 
“ Gmelin’s Lepidoptera.— The Lepidoptera Heterocera described by 
Gmelin and Zschach are so briefly characterised that their identification 
will be a work of time and trouble, and in many cases will be impossible. 
Six species are, however, figured, and four of these I was able satisfactorily 
to determine at the British Museum this year, with the kind help of 
Mr. Butler. 
Sphinx immaculata, Gel. i. 5, p. 2386; Sphinx, No. 283, Zschach, 
p- 95, t. 3, f. 283 = Chcerocampa capensis, L. 
Sphinx Pluto, Gimel.1.¢.; Zschach,1.c. No. 284 = Pergesa Pluto, Fabr. 
(vide supra), and may be regarded as the typical figure. : 
Sphinx octopunctata, Gel. l.c.; Zschach, 1. c. No. 286 = Cheerocampa 
Boerhavie, F’. (= Sph. Thyelia, L. ?) 
Phalena Cypria, Gmel. 1. ¢., p. 2403; Bombyx, No. 210, t. 3, p. 210, 
Zschach, = and supersedes Hyperchiria incisa, Walk. 
I may here remark that Hyperchiria varia, Walk. = Bombyx Io, Fabr. 
nec Cram. Cramer’s Attacus Io will therefore require another name; and 
I propose to call it Hyperchiria Vala.” 
“ Sphinges of Fabricius—Mr. Walker has left several Fabrician Sphinges 
undetermined. Sphinx asiliformis, F’., appears to me to be a species of 
Thyreus; S. Medea, F’. = Basiothia Idricus, Dru., according to Prof. 
Westwood: and S. Clio, F., seems to be synonymous with the same insect. 
S. minus, F’., is apparently synonymous with C. Boerhavie. It must 
be noted that Fabricius, in his ‘ Mantissa,’ wrongly placed his Pergesa Pluto 
(= Thorates, Hiibn.), as synonymous with C. Boerhavie, reversing the 
diagnoses, and consequently, in his Ent. Syst., we find C. Boerhavie 
described with the diagnosis of P. Pluto prefixed. 
“‘Cheerocampa Nessus, Dru. This species is figured by Cramer, t. 226 D, 
under the same name, but oddly enough without any reference to Drury, or 
to his having himself previously figured a species of Thyreus as Sphinx 
Nessus. Fabricius named Drury’s species Sphinx Equestris (Ent. Syst.
