980 [April, 1872 
4th March, 1872.—The President in the Chair. 
Ernest Kaye, Esq., of Penge, was elected a Member. 
Prof. Westwood exhibited living examples of Argas reflewus, from the crypt of 
Canterbury Cathedral, which species he had noticed at the Meeting on the 5th 
ultimo. Also another species of the same genus collected by Dr. Livingstone in 
Central Africa, where it annoyed the natives by entering the feet between the toes, 
causing pain and inflammation. 
Mr. S. Stevens exhibited an apparently undescribed species of Phycita, from the 
neighbourhood of Gravesend, remarkable for its pearly hue and Crambus-like form. 
Mr. F. Smith stated that he had received a further communication from Mr. 
Moggridge regarding the grain-storing ants at Mentone. Mr. Moggridge had con- 
fined a colony of ants in a glass vessel for purposes of observation, and he was now 
able to: tate positively that they fed upon the stored grain. 
Mr. H. W. Bates exhibited a series of British species of Carabus side by side 
with their nearest allies from Eastern Siberia. He stated that of fifty species of 
Carabus inhabiting the latter country, one only (C. granulatus) was found also in 
Western Europe. He recalled the attention of the Society to the zoological division 
of the globe into regions as proposed by Sclater, and urged that the Palearctic 
Region (including Europe and Northern Asia) was not a natural one, in so far as 
its Insect-fauna was concerned, however much it might be so as regards Mammals 
and Birds. Neither was there the difference between the Insect-fauna of the 
Nearctic (North American) Region and that of the Palearctic, that seemed to be 
assumed when the division was made: on the contrary, there was much resem- 
blance between the insects of Eastern Siberia and those of Western America. He 
considered an investigation as to the districts that presented the most peculiar 
forms as more philosophical for purposes of division. Prof. Westwood followed by 
pointing out the necessity for ascertaining the range of each species, and the varia- 
tion or modification it presents in different districts. Dr. Sharp said that the 
Spanish Carabi were mostly peculiar to the Iberian peninsula, and that those 
species occurring both there and in other parts of Hurope were modified. He also 
stated that the Siberian species of Oxytelus were all identical with those of Britain, 
whereas the Bledii were all different. 
Mr. Miiller exhibited a leaf of Cinnamomium nitida, from Bombay, bearing 
galls which he referred to the productions of an Acarus of the genus Phytoptus, 
thus showing the occurrence of this genus in India. 
Mr. Baly communicated descriptions of new species of exotic Cassidide. 
Mr. Kirby communicated notes on the Diurnal Lepidoptera described by 
Jablonsky and Herbst. 
Mr. Dunning read an exhaustive paper on the genus Acentropus, in which he 
gave a résumé of all that had been written on the subject. He was of opinion that 
the genus was undoubtedly Lepidopterous, and that probably one species only 
existed, for which he retained the name of Acentropus niveus. In his introductory 
remarks, he commented strongly upon reasons recently given for ejecting it from 
the Lepidoptera, as opposed to the opinions of all who had studied the subject, 
which opinions were borne out by his own investigations. He placed Acentropus 
in the vicinity of the Crambide and Chilonide.
