PROCEEDINGS OF SCIENTIFIC SOCIETIES. 39 
The Rev. H. 8. Gorham exhibited the following rare beetles, taken 
in the neighbourhood of Horsham, Sussex :—Platypus cylindrus, Fab., 
Lathrobium pallidum, Nordmann, Achenium humile, Nicolai, and Cryphalus 
abietis, Ratzeburg. [Coloured figures of the three first named will be found 
in Janson’s ‘ British Beetles,’ figs. 99, 112, 113.] 
Mr. H. Goss exhibited male and female specimens of a rare dragon-fly, 
Cordulia Curtisi, taken at Popesdown, Christchurch, Hampshire. Mr. 
M‘Lachlan made some remarks on the geographical distribution of this 
species. (See also Ent. Mo. Mag. for Sept. 1878, p. 92.) 
Mr. Meldola exhibited a male specimen of a moth from Jamaica, 
belonging to the genus Hrebus, and which was remarkable on account of 
its possessing large scent-fans or tufts on the hind legs. Although the 
function of these tufts had only recently been made known through the 
researches of Fritz Miiller, this species had been named LE. odorus (Phalena- 
Bombyx odora) by Linnzus. (See also Sloan's ‘Jamaica,’ vol. ii., p. 216). 
Mr. J. Wood-Mason exhibited specimens in alcohol of Gongylus trachelo- 
phyllus, Burm. (male and female), and of G. gongylodes, Linn. Saussure 
was of opinion that the former species was a variety of the latter, but 
Mr. Wood-Mason, after examining numerous specimens of both, had found 
good characteristic differences, and concluded that they were specifically 
distinct—a view which was corroborated by the difference in the colour of 
the under side of the prothoracic expansion, a distinction which he had 
long suspected, but of which he had ouly recently obtained good evidence. 
Knowing that Sir Walter Elliot, during his long residence in India, had 
superintended the execution, by native artists, of a multitude of coloured 
drawings of animals belonging to all groups, and thinking it probable that 
there might be amongst these some coloured sketches of Gonyylus, he 
applied to him for the loan of any drawings of Orthoptera he might still 
have in his possession, a request to which Sir Walter Elliot, with his usual 
generosity, at once acceded. Amongst these Mr. Wood-Mason had found 
a coloured drawing of the under surface of Gongylus gongylodes, which 
conclusively proved that the insect is coloured so as to resemble a flower 
with a white corolla, thus differing remarkably from the other species, in 
which the prothoracie shield is of a pale bluish violet inclining to mauve, 
and acquiring a reddish tinge towards the margins. Both species have the 
same black-brown transverse prosternal blotch. G. gongylodes was restricted 
in its distribution to the neighbourhood of Bangalore in Mysore and Ceylon ; 
one specimen, however, is in the National Collection from the Dharwar 
district South Mahratta country, obtained many years ago by Sir Walter 
Elliot himself. G. trachelophyllus, on the other hand, was only known to 
Mr. Wood-Mason from Midnapur, from the base of the Karakpur Hills 
near Monghyr. In 1871 he had received a specimen from Pegu, which 
was obtained by the late Mr. S. Kurz during a botanical tour in that
