larva had fixed its case prior to the assumption of the pupa-form, the instinct of the 
creature had been at fault, and the larva had omitted to make allowance for the growth 
of the plant, by means of which the case had been raised above the water, and the 
pupa had consequently perished. 
Mr. Stainton mentioned that from the galls on Gypsophila saxifraga, found at 
Mentone, of which he had exhibited a drawing at the previous Meeting (ante, p. x.), 
there had emerged two moths of the genus Gelechia, belonging to what he supposed 
he must call a new species allied to G. leucomelanella. The group of Gelechiz, how- 
ever, which fed on the Caryophyllacee were most difficult to deal with; new forms 
were continually discovered, intermediate between what bave hitherto been considered 
distinct though closely-allied species; it was not improbable that other intermediate 
links would be supplied until the whole series, thus made ntinuous, would require to 
be united—should he say, into one species ? 
Mr. M‘Lachlan thought the group in question was a good illustration of the 
“ phytophagic species” of Mr. Walsh. 
Mr. C. A. Wilson communicated a further instalment of his “ Notes on the 
Buprestidae of South Australia.” 
Prof. Westwood exhibited drawings of several species of Goliath beetles, which he 
proposed to describe, and for some to create new subgenera. 
Mr. Pascoe exhibited two new species of Articerus, and read the following note 
respecting them:— 
“ Of the eight known species of Articerus, five are from Australia; three of these, 
described by Prof. Westwood, have short thick antenne; another, described by the 
same author, has them remarkably curved; the species recently described by Mr. 
Waterhouse has longer antenna, but they are terminated by a compressed truncate 
club curved inwards at the apex. The two species before the Society have also long 
antenne, but gradually enlarging from the base to the apex, in one of them, however, 
expanding rather more rapidly when approaching the tip; one is from Mr. Odewahn, 
of Gawler, South Australia; the other from the Rev. George Bostock, of Fremantle, 
West Australia; they may be thus differentiated :— 
Articerus Odewahnii, n. sp. 
A. pallide ferrugineus; capite prothoraceque subtiliter punctulatis; antennis 
basin versus abrupte angustioribus. 
Long. lin. §. 
Hab.—Gawler. 
Articerus Bostockit, n. sp. 
A, rufo-testaceus, elytris dilutioribus; capite prothoraceque subcrebre punctatis ; 
antennis basi seusim angustivribus. 
Long. lin. 1. 
Hab.—Fremantle. 
“The former has compressed antenna, as may be seen by the section presented at 
the apex, whilst in the latter it is nearly or quite round. A. Odewalnii also has the 
head considerably smaller in proportion, and if examined sideways it will be found to 
be of nearly equal depth throughout; but the larger head of A. Bostockii begins to 
diminish under the eyes, and is drawn rapidly up so as to be scarcely more than half
