Mr. Fitch read a detailed report from the " Western Daily Mercury " on the 

 discovery of living Colorado-beetles in possession of a man near Plymouth, with 

 editorial leaders on the legal proceedings taken against that individual. 



Mr. McLachlan called attention to a remarkable memoir by Dr. Adler on 

 dimorphism in oak-gall Cgnipidce (see ante, p. 258). 



Mr. Pascoe read a paper on the Khyncophorous genus Hilipus, of Grerrnar, and 

 its neotropical allies, and exhibited a long series of species in connection therewith. 



Mr. Distant read " Descriptions of two genera and species of Rhynchota from 

 Madagascar." 



Professor Westwood communicated notes on Scleroderma and allies.

Peronea (Teras) Logiana, Schiff., = tristana, Hub. — I met with the 

 larva of this species for the first time in great abundance in Somerset- 

 shire, eighteen months ago. Wilkinson's description of its habits is 

 very good. When feeding on the bushes of Viburnum lantana in the 

 hedges, the discoloration produced among the leaves was surprising, 

 indeed, those on the lower portions of the bushes down the side of the 

 bank became a tangled mass of drawn-together and dead-leaf membrane, 

 only the under-side of each leaf being eaten away. The larvae were 

 active, slender, slightly flattened, with deeply divided segments — 

 more so than usual in this genus, — very pale yellowish, with large, 

 distinct, dull green or brown, internal dorsal vessel. Head very pale 

 yellowish, mouth darker, plates and feet almost colourless. Young 

 larvae remarkably colourless, except the dorsal vessel. On Viburnum 

 lantana, eating the under surface and parenchyma of the leaf, and 

 drawing the space between the ribs longitudinally together (much as 

 is done on a smaller scale by the larva of Litlwcolletis lantanelld), 

 living in a small chamber more closely drawn together at one end of 

 this space. Feeding through September, spinning up among the leaves. 

 Pupa brown. The moths emerged in considerable variety in October 

 and November. 



These Somerset larvae differed in colour from those described by 

 "Wilkinson, and by Kaltenbach, being yellowish rather than olive- 

 green. The latter author notices the curious habit of the species of 

 scraping off the down ("felt") of the under-side of the leaf (a habit 

 in which it resembles some of the larvae of the Pterophoridce), he also 

 states that the pupa has two oblique rows of short tufts of bristles on 

 each hinder abdominal segment.
