Mr. Chitty to him as //. granularis. The specimens were 

 taken at Deal in 1891, and probably all records of granularis 

 from Deal relate to this species. He also exhibited a specimpn 

 of the rare Trechus rivularis (incilis of Dawson), taken at 

 Wicken Fen in August 1900. The only other British speci- 

 mens of this insect are believed to be the original specimens 

 taken at Whittlesea Mere, and some afterwards found by Dr. 

 Power at Holme Fen. 



Mr. O. E. Jansox exhibited specimens of Xeojjheedimus 

 ^melaleuGus, Fairm., a goliath beetle from Upper Tonkin, and 

 remarked that the white colouring was derived from a dense 

 clothing of peculiar semi-transparent coarse scales which were 

 apparently easily removed by abrasion, and seemed to partake 

 of the nature of the " fugitive " scales found upon freshly- 

 emerged specimens of Hemaris and other Lepidoptera. 



The President read the following communication on " Pro- 

 tective Resemblance and other modes of Defence adopted by 

 the Larvfe and Pupee of Natal Lepidoptera " from Mr. G. F. 

 Leigh. 



" Having devoted a great deal of time during the past two 

 years to finding and preserving the larvse of Natal Lepidoptei'a, 

 it appeared to me that some account of the most striking 

 examples, as well as of the conclusions to which I have been 

 led, would be useful. 



" Among the butterflies the larvpe of Papilios demodocus, poli- 

 cenes, hrasidas and nireus do not appear to conceal themselves, 

 and I have never seen birds, hornets or spiders attacking 

 them. Fapilio morania, until the last change of skin, is also 

 very conspicuous ; but then the larva becomes of a perfectly 

 green colour, exactly resembling the food-plant, and is vei-y 

 difficult to detect except during movement. The larva progresses 

 in a characteristic jerking manner, spinning a web all the time. 

 Fapilio darda7ius (cenea) is however quite different : in the 

 first and second stages the larva is chocolate and white, and 

 always feeds on the leaves near the ground and among the 

 undergrowth. During the third and fourth stages, on the 

 other hand, the larva is green with small white and blue 

 markings. It is then extremely difficult to find, so closely 

 does it resemble the colour of the older leaves of its food-plant.
