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 Coreide”; 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.

Exhibitions, de. 
The Rev. A. EK. Eaton exhibited a dried specimen of the nymph of a 
species of Huthyplocia, Etn., a genus of the Ephemerida known hitherto 
only in the adult condition. The example exhibited belonged to the Musée 
Royale of Brussels, and is labelled “ Brésil”. Pictet, in his ‘ Hist. Nat. des 
Ins. Néuropt.’, Ephem. p. 158, pl. xv. 2—4(1843—5), mentions and figures 
two somewhat mutilated nymphs of the same genus from South America or 
Brazil, whose exact affinities have remained undetermined until now. 
EKuthyplocia is represented in museums by several Brazilian and Central 
American species, but H. Hecuba, Hag., is the only one that has been 
described. 
Mr. H. A. Fitch exhibited a larva of Zeuzera e@sculi, from which many 
hundreds of a species of Hneyrtida (Copidosoma truncatellum, Dalm.) 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 Kastbourne, 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, 
thoroughly saturated with vinegar, mustard, &c.; these larve afterwards 
pupated on the cork, and from these pup the enclosed flies were bred.” 
Mr. Fitch remarked that when this fly was exhibited at a previous meeting 
he thought a very ungenial habitat was assigned to it (Proc. Ent. Soc. Lond. 
1877, p. xv; August, 1877), but one of which this exhibition was quite 
confirmatory.
