necessarily restricted in their range, whereas those found in the plains were 
of wide distribution. He remarked that all the species of the genus 
Oxytelus, seen by him, from Eastern Siberia, were specifically identical with 
those of Britain, whereas of the genus Bledius no species was common to 
both countries. 
Messrs. Weir, Miiller, Janson, M‘Lachlan, &c., also took part in the 
discussion, and the two latter remarked on additional instances of the 
occurrence of allied forms in Eastern Asia and North America, as exhibited 
in the genus Pteronarcys among the Neuroptera, and Cupes in Coleoptera. 
Mr. Miller exhibited galls of an Acarus, probably a Phytoptus, from 
Bombay, concerning which he read the following notes :— 
“ My friend Mr. F. Mvore has kindly presented me with some leaves of 
Cinnamomum nitidum, from Bombay, exhibiting on their upper surface 
isolated, rusty-brown, smooth and hard pouch-shaped excrescences, each of 
the size of a large pin’s head. These excrescences are hollow, and provided 
on the under side of the leaf with an opening equal in diameter to the basin 
on the upper side. The sight of these objects enables me to assert the 
existence in India of a species of gall-producing Acaride, probably four- 
footed, and allied, or perhaps belonging to the extensive European and 
American genus Phytoptus. In size and structure these Cinnamomum 
pouches tally with those of the European Phytoptus gall, called by Bremi 
Cephaloneon solitarium, of which my collection contains British and Conti- 
nental specimens. But they differ from the latter in being less restricted 
at the basis, with both inside aud outside quite smooth, and in exhibiting 
on the under side of the leaf a slight rim surrounding the open pouch. The 
absence of all pubescence from the pouch chiefly distinguishes them from 
the European form, and this character is quite in accordance with the highly 
polished, smooth, outer texture of the healthy leaf of Cinnamomum.” 
Papers read. 
-Mr. Baly communicated descriptions of various new species of Cassidide, 
from Ecuador and Nicaragua. 
Mr. W. F. Kirby communicated “ Notes on the Diurnal Lepidoptera 
described by Jablonsky and Herbst in their ‘ Natursystem aller bekannten 
Insecten’.” 
Mr. Dunning read a memoir on the genus Acentropus, in which he 
brought together a réswmé of all that had been written on the subject. 
After commenting upon the opinions expressed by various authors as to the 
position of the genus, he arrived at the conclusion that it is truly Lepidop- 
terous; and, furthermore, he had failed to find valid reasons for considering 
that more than one species existed, for which he retained the name 
Acentropus niveus.—R. IM‘L. :
