side, but the middle specimen was in reality a spider of the genus Salticus, having 

 its anterior legs purposely removed, and then presenting a -wonderful resemblance to 

 the Ant, wliieh, like it, inhabits trees. 



Mr. Cole exhibited a series of magnificent species of Bomhycidce sent from 

 Natal by Dr. Seaman. 



Mr. Bates said that Mr. Darwin had put to him a question affecting the theory 

 of sexual differences in the eye-like spots on butterflies. Mr. Weir considered that 

 the number of these spots on the under-side of Pararge Hyperanthus were more nu- 

 merous in the $ than in the $ , and Mr. Butler thought that differences of this kind 

 existed in the genus Drusillus. 



Mr. Bates read a paper on the Greodephaga of China, complementary to that re- 

 cently read by him on the Japanese species of the group. Many of the species were 

 collected by Mr. G-eorge Lewis at Kewkiang, in North China, and five-sixths of these 

 occurred also in Japan. 



Mr. Dunning read a further note on Ati-opos pulsatoria, with reference to Dr. 

 Ilagen and Mr. W. Arnold Lewis. Mr. Dunning said that he had been sanguine 

 enough to expect that when he had pointed out Mr. Lewis' mis-statement in the charge 

 made by him against Dr. Hagen, it would have been at once withdrawn. However, 

 instead of this having been done, Mr. Lewis had repeated his charge, and stated that 

 the difference between Mr. Dunning and him was only one of words. Mr. Diu\ning 

 said, as this was Mr. Lewis' understanding of what he had written, he was not sur- 

 prised that Mr. Lewis had misrepresented Dr. Ilagen, and that Mr. Lewis must enter- 

 tain a very low estimate of the intelligence of entomologists, if he thought they would 

 be convinced by such a verbal quibble. Mr. Lewis had brought fresh charges 

 against Dr. Ilagen with reference to Tennes fatidicum, but Mr. Dunning said he had 

 not previously alluded to this ease, and that it was as if Mr. Lewis, in prosecuting 

 a man for bigamy, had said in reply to the defence, that at any rate he had been 

 guilty of forgery. Mr. Dunning declined to go into this matter, and concluded by 

 paying a high compliment to the laboui's of the distinguished entomologist who 

 had been thus maligned by Mr. Lewis. 



Prof. Westwood, in asking the Meeting to return a vote of thanks to Mr. 

 Dunning, said it was like breaking a fly upon the wheel, and he was sure that Dr. 

 Ilagen wovdd have the good sense not to feel serious annoyance at the silly attack 

 Mr. Lewis had thought proper to make upon him. 



Mr. Miiller made some remarks with reference to a beetle {ArcBOcerus coffete), 

 which he had taken alive in 1862, at Basle, while watching the unpacking of a bale 

 of coffee from Java. He had lately received a letter from a friend at Basle, stating 

 that he could now take any quantity of the species in that town. He thought this 

 fact showed how insects living on merchandize are spread along the main trade 

 routes, and become gradually acclimatized — Basle being one of the chief continental 

 markets for storing foreign merchandize. 



Mr. Miiller also stated that a case of ground nuts (Arachis hypogaa) arrived 

 in London in the summer of 1863, from Sierra Leone, and that the husks were 

 riddled, and the kernels half eaten, by myriads of larvae and perfect insects of 

 Tribolium femgineum, accompanied by the corresponding stages of a species of 

 Rhizophagus, preying on the former. The cargo was allowed to remain during 

 the months of August, September, and October, the whole being rendered worthless 

 through the delay and ignorance of the owner.
