THE ENTOMOLOGIST. 97 



names of Lepidoptera occurring in Perthshire, by F. B. W. 

 White, is the leading contribution in Entomology : from this 

 we learn that Acronycta Psi, Mamestra Brassicas, Agrotis ex- 

 clamationis, Triphajua pronuba, Cerastis Vaccinii, &c., &c., 

 are found in Perthshire : their absence would have been 

 remarkable ; their presence certainly is not. Wherefore 

 should it be recorded ?

35. T/te reiinhibifion of Fluid ejected by Tortrix Larva. 

 — Mr. Gascoyne, in No. 5 of the 'Entomologist' (Entom. 

 69) has done me the favour to confirm njy statement of the 

 above fact, with the additional information that the habit is 

 not peculiar to the Tortrices, he having observed it in larvae 

 of Bombyces and Geometrae. But that gentleman thinks that 

 it is " confined to cases where the fluid has not been pro- 

 jected, but has remained attached to the head." Tliat this is 

 not the case I can assure him, having often ajjplied the 

 moulh.of a larva to the fluid it had before ejected and left, 

 when it would remain with its head in the position I had 

 placed it until all the moisture was sucked up. This I did in 

 the belief that the fluid was the chylaceous or nutritious 

 juice of the larva, and therefore was anxious that it should 

 not be lost. Some larvt^ eject it in abundance and upon the 

 slightest disturbance, while others I have never seen do so 

 luider any provocation. In all cases 1 believe it is emitted 

 as a means of defence against a real or imaginary aggression. 

 With respect to the colour of the fluid, subsequent observa- 

 tion has shown me that there is little relation between that 

 and tlie colour of the larva. The colour of the juice will, it 

 is probable, be modified by that of the food-plant. — John

36. Perouea permutaiia at iSew Briyhioii. — 1 have the 

 pleasure of recording the capture, at New Brighton, on Au- 

 gust 16th, of above thirty fine specimens of Peronea permu- 

 lana. Enough for myself and some for my friends. — Id. 



37. Gonepteryx RJtanini in Ireland. — 1 observe you speak 

 hesitatingly of the occurrence of this beautiful insect in Ire- 

 land (Entom. 76). I am happy to be able to remove the
