between Borneo and the Philippines. He remarked that Ornithoptera trojana was 

 allied to 0. Broohiana, Wall. 



Mr. R. McLachlan exhibited, and made remarks on, several examples of JEschna 

 borealis, Zett., a little-known species of European Dragonflies. He said that some 

 of the specimens were captured by himself at Rannoch, Scotland, in June, 1865, 

 when he was accompanied by Dr. Sharp and the late Mr. E. C. Rye. The other 

 specimens were taken at Lulea, North Sweden, and in the Upper Engadine (5000 to 

 6000 ft.), in Switzerland. 



Mr. W. H. B. Fletcher exhibited specimens of Agrotis pyrophila from various 

 localities, including two from Portland, three from Forres of a smaller and darker 

 form taken by Mr. Salvage last year, and a melanic specimen from Stornoway, at 

 first supposed to belong to A. lucernea, but which, on closer examination, was seen 

 to be referable to this species. He also exhibited series of Triphcena orbona from 

 Stornoway and Forres, and T. subsequa from Forres and the New Forest. The 

 specimens of T. subsequa from Forres were more distinctly and richly marked than 

 those from the New Forest, and were also rather more variable in colour. 



Dr. Sharp exhibited specimens of Proculus Goryi, Kaup, found by Mr. Champion, 

 in Guatemala, prepared to show the rudimentary wings under the soldered elytra. 

 Dr. Sharp called attention to the existence of a peculiar articulated papilla at the 

 base of one of the mandibles ; and he also showed sections of the head of Neleus 

 interruptus displaying this papilla, as well as the articulated teeth on the mandibles. 



The Rev. Canon Fowler exhibited specimens of Agapanthia lineatocollis, Don, 

 and remarked that they were able to produce a distinct stridulation by the movement 

 of the head against the prothorax, and of the hinder part of the prothorax against 

 the mesothorax; they were also able to produce an unpleasant scent. He further 

 remarked that Dr. Chapman had lately informed him that Erirrhinus maculatus, F., 

 had the power of stridulating strongly developed. He also exhibited a specimen of 

 Barynotus, taken in Norfolk, which was apparently an abnormal example of 

 B. obscurus. 



Mr. Edward Saunders exhibited, on behalf of Mr. G. A. J. Rothney, in illus- 

 tration of his paper on Indian Ants, specimens of the following: — Camponotus 

 compressus, and fragments of Solenopsis geminatus destroyed by it ; Camponotus 

 sp. ?, with a mimicking spider {Salticus sp.) ; Pseudomyrma bicolor, with its 

 mimicking Salticus, and a new species of Rhinopsis, viz., nificomis, Cameron, also 

 found with it, and closely resembling its host ; Diacamma vagans, Holcomyrmex 

 indicus, with specimens of the grain which it stores and the chaff which it rejects ; 

 and Pheidologeton laboriosus, with specimens of the various larvae, shells, &c, which 

 it collects ; and Aphosnogaster sp. with the pieces of Minosa, &c, with which it 

 covers its nest. 



Mr. G. A. J. Rothney communicated a paper entitled " Notes on Indian Ants." 

 Mr. Lionel de Nice'ville communicated a paper entitled "Notes regarding 



Delias Sanaca, Moore, a Western Himalayan Butterfly." 



Mr. H. J. Elwes communicated a note in support of the views expressed by 



Mr. de Nice'ville in his paper.— H. Qoss and W. W. Fowler, Joint Hon. Sees.
