Captain Cox exhibited a series of drawings illustrating the transformations of Bri- 

 tish Lepidoptera, beautifully drawn from Nature by Mrs. Cox ; amongst them were 

 the larvae of ei;;hl species of the genus Eupithecia. 



Mr. Waterhouse exhibited a series of specimens of the British species of the 

 genera Rhizopliagus and Monotoma ; the .species of the former genus determined from 

 Erichson, and of the latter from Aube's ' Monograph,' as follows: — 



Rhizophagcs. 



1. iiitidulus 5. ferrugineus 



2. dispar 6. pcrforatus 



3. bipustulalus 7. parallelncollis 



4. depressus 8. cribratus 



to which may be added the R. cteruleus, Walll. 



Monotoma. 



1. conicicollis 5. quadricollis 



2. anguslicollis 6. quadrifoveohita 



3. picipes 7. longicollis 



4. spinicollis 



Mr. Newman exhibited a remarkable dark variety of Argynnis Euphrosyne, and a 

 specimen of Heilipus brachypterus infested by Fungi, and made the following com- 

 munications respecting them: — 



Remarkable Variety of Argynnis Euphrosyne. 



" Mr. Weaver has placed in my hands a specimen of Argynnis Euphrosyne so re- 

 markable thai 1 think the Members of this Society will take some interest in examining 

 it. The specimen is rather above the average size, and the spalhulate terminal por- 

 tion of the antennae is of nearly double the usual length ; the apex itself is very much 

 flattened and twisted backwards. The upper surface is nearly black, the usual tawny 

 spaces being almost obliterated by the suffusion and union of the black markings; 

 this is more particularly the case with the hind wings, in which the only remaining 

 traces of tawny are confined to the anal angle, and six obscure spots just wiihin the 

 outer margin. On the under side the colours of the fore wings are more suffused than 

 usual, but otherwise not remarkable; but the distribution of colour in the hind wings 

 is totally changed ; ihe prevailing colour towards the base is greenish yellow ; the 

 marginal silver spots are changed into large silver markinos of an elongate- conical 

 form, and the middle one of the seven unites with the large silver spot in the centre 

 of the wing." 



Fungus on a Rhyncophorous Beetle. 



" Mr. Ingall has placed in my hands a specimen of Heilipus brachypterus which 

 is in the finest condition, and looks as though it had been pinned while living, yet has 

 several specimens of a black thread-like fungus, probably a Sphaeria, growing from 

 various parts of i(s body ; three of these, about an inch in length, issue from the inter- 

 stice between the prothorax and elytra ; a fourth issues beneath the bead, from the 

 interstice between the head and prothorax ; and there are many shorter ones in
