 This species I suspect, as well as that described under the name 

 P. chlorolineatus, is but a local variety of P. moniliferus. In speci- 

 mens from some localities, the scales forming the markings are of a 

 beautiful golden green colour. I have before me individuals in which 

 the scales on the elytra arrange themselves into bands — one at the 

 base of the elytra, one in the middle, and one near the apex ; the 

 first and last of these bands are curved. Such specimens make an 

 approach to the P. moniliferus, but differ in the bands being much 

 broader. Again, there are specimens connecting this intermediate 

 variety more closely on the one hand with the P. orbifer (where the 

 elytra are covered with scales with the exception of three circular 

 areas arranged in a transverse line near the base of the elytra, three 

 a little behind the middle, and one near the apex), and on the other 

 with the moniliferus. 



Sp. 20. Pachyrhynchus rugicollis, W. Ater ; thorace distincte 

 rugoso-punctato, punctis squamis viridibus ornatis ; elytris rufo- 

 piceis, vel piceis, leviter punctato-striatis et ad apicem quasi squa- 

 mis viridibus pulverulentis. 



April 5th. — W. W. Saunders, Esq., President, in the Chair. 



The President exhibited various splendid species of moths from 

 Northern India. 



Mr. Bainbridge exhibited several species of insects found in cigars, 

 including a small species of Latridius and a species of Haltica, 

 which Mr. Waterhouse stated to be very similar to a unique Bri- 

 tish species. Some masses of excrement, apparently of a Lepido- 

 pterous larva, were also found. Mr. Gutch stated that it was che- 

 roots and not Havannah cigars that were attacked by these insects. 



Mr. Westwood exhibited some singular Coleopterous insects from 

 the collection of Mr. Melly, including Acropis tuberculifera, Burm., 

 and a new genus allied to Lyctus with remarkable antenna?, &c. 



Some larvae of Trogosita Caraboides were forwarded to the Society 

 by Messrs. Norton, Kilburn, and Co., which were found among some 

 China raw silk recently imported from Manilla, to which they had 

 caused considerable injury, the silk having been eaten or gnawed in 

 many places, by which the value of some bales was depreciated to 

 the extent of twenty-five per cent. 



An extract was read from a letter addressed to Mr. Westwood by 

 Mr. James Duncan, relative to a silk cocoon which is attached by 

 a long peduncle to the twigs of trees in India, and suggesting the
