the end of the year), and the only suggestion I would throw out, to account for the 
unusual method of luminous emanation, is that the close congregation of large 
numbers of insects, from the small space afforded by the bushes in question, may have 
given rise to the synchronous emission of the flash, by the force of imitation or 
sympathy. Mr. Montgomery, of the Survey Department here, also fully corroborates 
the habit of our Pegu fireflies simultaneously emitting their light, but adds he has 
only remarked it under conditions similar to those described above, in low swampy 
ground. It still remains, therefore, to be decided if the insect is different from the 
ordinary one, or if, as I ‘am inclined to think, the simultaneity is produced by 
sympathy and great crowding of individuals——W. THEoBaxp, jun.” 
Mr. M‘Lachlan mentioned that the genus of Hydropsychide (Trichoptera) described 
by him in the ‘Transactions ’ (third series, v. 270), under the name of Sciops, was 
identical with the Hydromanicus of Brauer (Verh. K. K. zool-botan. Gesellschaft in 
Wien, xv. 420), which had priority over Sciops, so that the latter name must sink. 
The two species described by Mr. M‘Lachlan were, however, both distinct from the 
Hydromanicus irroratus of Dr. Brauer. 
Mr. Janson exhibited a small collection of Jamaican insects, the produce of the 
first three weeks of Mr. C. P. Gloyne’s residence near George Town; amongst a few 
Hemiptera, an Emesa was the most interesting; and amongst the Coleoptera, an 
Epitragus, a Charactus, Hebestola, Desmophora, Notoxus, Helops, &c. 
The Secretary read a further instalment of “ Notes on the Buprestide of South 
Australia,” communicated by Mr. C. A. Wilson, of Adelaide. 
Mr. Pascoe read the following description of a new genus of Tmesisternine :— 
“The Queensland insect described below is closely allied to Spiutheria, from the 
opposite land of New Caledonia. It is exceedingly interesting as being a second form 
of agroup which, almost excladed from Australia, abounds in New Guinea and the 
Celebes (Mr. Wallace’s collection alone contains nearly a hundred species), and is 
represented as far as Timor to the West, Manilla to the North, and New Zealand to 
the South. It is also interesting from the remarkable structure of its mesosternum, 
which is produced anteriorly into a sharp spine, overlapping the prosternum. The 
following characters separate the genus from Spintheria and from all other known 
forms of Tmesisternine.:— 
ANASTETHA, 0. &. 
Antenne setacee, corpore longiores. Prothorax basi latus et bisinuatus, lobo scutellari 
producto. Sentellum elongatum, angustatum. Femora postica haud incrassata.
