THE ENTOMOLOGIST. 87 



appeared in the case ; they were observed running about the 

 oak-stump for about three weeks, when, unable to escape, 

 they died, and their remains were afterwards swept away. 

 The same thing occurred in 1867, and in 1868, on the morning 

 of the Meeting, the Clytus had made its third appearance. 

 The large quantities of camphor placed in the Museum cases 

 did not seem to affect them, or to prevent the development 

 of the beetle. 



Mr. Janson said that camphor, though useful in preventing 

 the entry of insects, was powerless to destro}' them : at the 

 same time he doubted whether the Clytus had been repro- 

 duced in the Museum ; the insect probably remained in the 

 larva state for two or three years, and it was quite possible that 

 all the larva? from which the successive broods of 1866, 1867 

 and 1868 had appeared were present in the wood on its ad- 

 mission into the Museum in 1865. 



May 4, 1868. — H. T. Stainton, Esq., Vice-President, in 

 the chair. 



Mr. W. C. Boyd exhibited a number of skins of larvae of 

 Lepidoptera, admirably prepared by Mr. Davis, of Waltham 

 Cross, so as to preserve both the form and colour of the 

 caterpillars. 



Mr. Trimen exhibited a crippled specimen of Saturnia 

 Pavonia-minor, which, owing probably to the form and 

 smallness of the box in which it was confined, had attempted 

 to emerge from its cocoon tail foremost, but failing in the 

 attempt was found fixed with its head in contiguity with the 

 head of the pupa-skin. 



Mr. F. Smith exhibited a larva which he believed to be a 

 Xantholinus, found by Mr. O. Janson whilst digging in a 

 sandbank at Snaresbrook : attached by their hinder ex- 

 tremities to the under side of this larva, on the 5th, 7th, 9th 

 and 11th segments respectively, were four pupae of a Hy- 

 menopterous parasite, probably a Proctotrupes. ; 



Mr. Smith invited attention to a pamphlet by Col. Taylor 

 on the coffee-borer of Ceylon, and read some interesting 

 extracts : — " A very prevalent opinion exists, I believe, that 

 the borer may come to nothing, or it may exterminate our 

 plantations entirely. 1 confess that when I read of the suc- 

 cesses and failures of various kinds of cultivation, and reflect
