great advantages which would result, in a commercial point of view, 

 from the discovery of a chemical solvent for the gum, by which the 

 silk threads of the cocoons of various large species of exotic moths 

 are glued together. Mr. Westwood added, that the cocoon of the 

 Indian Phalcena Paphia, described and figured by Roxburgh in the 

 Linnsean Transactions, agreed with the description given by Mr. 

 Duncan. 



A memoir was read by Mr. G. R. Waterhouse, containing de- 

 scriptions of various Coleopterous insects brought from the Philippine 

 Islands by Mr. Cuming.

Mr. Waterhouse considers this insect as allied to the genus Ma- 



cronota (and not to Goliuthus) , approaching nearest to M. Rhinophyl- 



lus, and that it forms the type of a distinct subgenus (especially 



from the difference in the structure of the feet), for which the name 



of Phadimus is proposed. 



Lomaptera cupripes, W. Viridis, elytrorum marginibus pedibusque 



cupreis. Long. corp. lin. 14-15. 

 " This approaches very nearly L. valida, G. and P., but the club 

 of the antennae is black and not yellow, as in that species." 



Lomaptera nigro-senea, W. Nigro-cenea, corpore subtils, antennis 



pedibusque nigris. Long. corp. 1 unc. 

 " Like L. cupripes in form, but of a smaller size and aeneous black 

 colour." 



Macronota Philippinensis, W. Nigra; antennis, palpis, tibiis tarsis- 

 que piceo-rubris ; capite lineis duabus, thorace lijieis tribus, scu-

Macronota nigro-cserulea, W. Nigra nitida, indistincte caruleo- 



tincta. Long. corp. I unc. 1 lin., lat. 6 lin. 

 " This species is remarkable for its uniform bluish black colour, and 

 is rather larger than M. Diardi, G. and P."
