Thera Armaria. July and August. 



Acasis viretata. May. 



Zerene rubiginata. June. 



Aleucis pictaria. Where this insect comes from is a mystery. It 

 is found, but very rarely, in the month of April, sitting on the paling. 

 Search has been made for it by beating the over-hanging fir-trees, and 

 it has also been looked for with a light at night, but without success. 

 Nothing is known of its early states^ or the food of the larva. The 

 only other known locality for this species is near Colchester, where 

 several once came to a light in a room.

On the Impalement of Insects on Thorns. — I cannot quite agree with the suggestions 

 (Zool. 2962, 2971) that the impalement of insects on thorns is the effect of accident; 

 in some cases, it doubtless is so, but in the majority of instances, I am almost convin- 

 ced that such is not the fact. I have always understood that the red-backed shrike 

 (Lanius Collurio) transfixes insects in that way ; and though I certainly have not had 

 quite positive proof of this, I once met with an instance which was almost convincing.
