agglutinated together. The moth flies at early dusk, and rests amongst 
the clematis during the day. Specimens of the moth and eggs were 
exhibited in illustration. ; 
‘Mr. E. A. Fitch exhibited an ear of wheat on which were between fifty 
and sixty skins of Siphonophora granaria, all of which, without exception, 
had produced an Allotria or Aphidius. He also remarked that from his 
observations in one particular field he should think quite 90 per cent. of the 
Aphides, which were numerous, were infested with these parasites. 
Prof. Westwood communicated the “ Description of a new genus of 
Hymenopterous insects” (Dyscolesthes canus). The species, which is from 
Chili, is of somewhat doubtful affinities, but was thought to be an aberrant 
form of the Formicide or Scoliida. 
Mr. A. G. Butler communicated a continuation of his “ Descriptions of 
new genera and species of Heterocerous Lepidoptera from Japan,” the 
descriptions of fifty Geometre being included in the present paper. 
Mr. R. Trimen communicated a memoir “On some new species of 
Lihopalocera from Southern Africa,” six new species being described, from 
the extra-tropical region of South Africa. 
Mr. C. O. Waterhouse communicated some “ Descriptions of new 
Longicorn Coleoptera from India, Japan, and Africa.” 
Mr. W. L. Distant read the “ Descriptions of some new Neotropical 
Pentatomide and Coreida”; also the “ Description of the female sex of 
Morpho Adonis, Cram.” In the discussion on this last paper Mr. Meldola 
and Mr. Kirby made some remarks on the occurrence of dimorphism in the 
genus Morpho.

The Rev. A. E. Eaton exhibited a dried specimen of the nymph of a 
species of Huthyplocia, Etu., a genus of the Hphemeride known hitherto 
only in the adult condition. 
Mr, E. A. Fitch exhibited a larva of Zeuzera esculi, from which many 
hundreds of a species of /’ncyrtide had emerged ; these were also exhibited, 
and, considering their vast numbers from a single host, he thought it one 
of the most remarkable cases of parasitism that had come under his notice. 
The lepidopterous larva had been received from Miss R. M. Sotheby, of 
Eastbourne. 
Mr. Fitch also exhibited many specimens of Drosophila cellaris, with 
their pupa-cases ; these flies had been bred in a bottle of “ Piccalilli” pickle, 
and were received from Mr. Charles Foran, of Eastbourne, with the following 
history :—‘ About three weeks since a bottle of Piccalilli pickles was opened, 
and a number of small white maggots were found feeding on every - 
piece of pickle, which consisted mostly of cauliflower and cucumber,
