Mr. Blackmore exhibited Lepidoptera and Coleoptera captured by him at Tan- 
giers during last winter. Among them was a long series of the true Anthocharis 
Eupheno, Linné. A beetle, Pimelia scabrosa, was remarkable for its monstrous 
antennz, these organs being furcate. 
Mr. F. Moore exhibited cocoons of a species of Sagra from Bombay, collected 
by Mr. Newton. These cocoons were placed, many together, in large galls, or 
swellings of the stems, of Cocculus macrocarpus, a creeping plant. 
The President read an extract from a letter from Mr. Everett, from Sarawak, 
remarking on cases of mimicry in some spiders and caterpillars, these creatures 
having a most deceptive resemblance to pieces of bird’s dung. 
Mr. Miiller exhibited galls on Ammophila arundinacea found by Mr. Trail, near 
Aberdeen. 
Prof. Westwood made some observations on certain minute Acari, especially 
with reference to a species which causes the minute galls on the leaves of the pear 
trees. This species, together with that infesting the buds of black-currant, and 
others, formed a distinct group distinguished by the possession of only four legs, 
and he proposed to institute for their reception a genus under the name of Acarellus, 
the pear species being A. pyri. Mr. Miiller suggested that these forms were iden - 
tical with those described by Dejean under the name of Phytopus. 
Mr. Jenner Weir communicated ‘“‘ Further observations on the relation between 
colour and edibility of Lepidoptera and their larvee.” 
Mr. A. G. Butler read a “ List of species in a collection of Butterflies sent by 
Mr. Ansell from Kinsembo, 8.W. Africa.” 
Mr. H. W. Bates read “Contributions to the Insect-fauna of the Amazons 
(Coleoptera ; Longicornia, Fam. Cerambycide). 
Mr. F, Walker communicated a ‘‘ List of Hymenoptera collected by Mr. J. K. 
Lord in Egypt and Arabia.”
