extremity of the body was obtuse, and also emitted two bristles, and the body itself 
was marked with very numerous transverse rows of minute dark dots. These creatures 
were also found dead in vast numbers on the inner surface of the sheathing-leaves of 
the dried-up buds. On one of the diseased buds were also found several specimens of 
a full-grown Acarus belonging to the genus Nothrus, and evidently forming a new 
species distinct from any figured by Koch. The genus, or rather subgenus, Nothrus 
forms part of the group Oribata, but Prof, Westweod was inclined to believe that the 
minute creatures were not the young of the Nothrus, but of some species of Tetrany- 
chus, some of the species of which are found upon trees, spinning extensive webs, as is 
the case with I. telarius. The only other recorded instance of a four-legged state of 
individuals among the Acaride occurred in the closely allied form figured by Dugeés 
in the ‘ Annales des Sciences Naturelles, 2nd series, vol. ii. pl. II. A, under the name 
of the “Acarien du galle de Tilleul,” found in galls on the leaves of the lime-tree, 
which, from the structure of its palpi, mandibles and legs, M. Dugés was inclined to 
refer to the neighbourhoud of Tetranychus. In every other recorded immature state of 
Acaride the animals possessed six legs. The question of the introduction of such 
great numbers of these minute creatures within the closely-packed leaves of the 
currant buds was difficult of explanation, but Mr. Stainton suggested that the eggs 
had been introduced intu the immature buds in the previous autumn. 
Prof. Westwood also exhibited a remarkable new species of butterfly from East 
India, which, although presenting all the general appearance of a species of the 
Brazilian genus Brassolis in its robust body and wings and in the coloration of the 
latter, belongs to the Lycwenide, having the veins of the fore wings arranged as in 
Amblypodia Timoleon. ‘The following are its characters :—

Mr. Francis Walker communicated a paper entitled “ Descriptions of undescribed 
Chalcidites.’ The whole of the species belonged to the genus Smiera, were discovered 
by Mr. Bates in the Amazon country, and are now in the collection of the British 
Museum.—J. W. D.
