fed larvae. The cause of this is, I am fully convinced, the 

 want of sushine with us, our cold and wet weather, which 

 weakens and dwarfs them, as the following table of figures 

 will show pretty conclusively: — 



Bred specimens from English larvae, i.e., found at large 

 in this country. Liverpool : — Out of a large number bred 

 one female only reached 3|- inches, whilst the largest male 

 was only 2^ inches. From io6 bred by myself from Deal 

 larvae, the largest female measured 3 Jg inches, the largest 

 male measured 2f inches ; average males, 2^ inches ; average 

 female, 2f inches. From a number bred by Mr. J. A. 

 Cooper from Essex larvae, largest females, 2f inches ; largest 

 males, 2f inches. 



Contrast these measurements with the following from 

 caught imagines. The largest female caught by Mr. J. T. 

 Williams measured 3f inches, and the smallest 3|- inches ; 

 whilst the males measured 3^ inches. From Kingsdown, 

 Kent, $ , 3^ inches ; from Aberdeen, ? , 3^ inches ; from 

 Plymouth, ? , 3 ^-^g inches ; Dartford, Kent, 3^ , 3 inches ; 

 Dublin, c?, 2^0 inches. 



All these caught examples agree with French types in my 

 possession, viz., females, 3f inches full ; and males, 3^ inches, 

 and point most conclusively to their probable French 

 origin, as not a single case of known bred English specimens 

 ever reach the size of the caught moths, an average English 

 ? being 2f inches ; an average English $ , 2^ inches only. 



Mr. Billups exhibited some very curious and beautiful 

 forms of Exotic Orthoptera, Hemiptera, and Homoptera, 

 amongst others, several species of Acripexa and Necroscia 

 from Mongpo, Sikkim, taken at a height of 4,000 feet 

 above the sea ; a species of ConocepJiahis from Central 

 America, imported into this country in Orchids, two species 

 of Homoptera of the family Fulgoridae, not yet determined, 

 as also some strange-looking Hemiptera from the Island of 

 Celebes, and one specimen of an Hemipteron, Daladev 

 acitticosta, from Burmah. In addition, this gentleman also 

 exhibited three very brilliant species of Phytophaga, or 

 plant-eating beetles of the family SagridcE : S. buquetii, Lac, 

 from Java, ^. chrysocJilora, Lac, from Australasia, and Sagra 

 cceruleata, Lac, from Madagascar.
