frequent amongst the bushes. I think there is no insect more 

 elegant than this : the large wings so filmy and transparent, 

 the delicate network tracery of the green nervures, and the 

 graceful manner in which they close, the slender body, and 

 the golden prominent eyes, are, I think, unrivalled. It is a 

 pity that it gives out so disgusting an odour when handled. 



F. — Have you ever observed the remarkable appearance 

 presented by the eggs of this fly ? Each one is jelevated on 

 a slender footstalk, as a flower grows on its stem, the lower 

 end being attached to a leaf, or other substance. As they 

 are often arranged in regular rows, and all of one length and 

 thickness, they look very curious, and would hardly be sus- 

 pected to be the eggs of an insect ; they look somewhat like 



the capsules of some mosses. A fine Hymenopterous 



fly, the White-bodied €imbex (Cimbex lO-maculata) was 

 lately evolved from pupa in my box : the larva of which, 

 with some others, I took from willows in August last : it 

 was pale green, with a blue band down the back. The per- 

 fect insect is not so large as a specimen I obtained in New- 

 foundland. The common Downy Cimbex (Cimbex St/lva- 

 ticaj is becoming numerous : I perceive these flies are the 

 same dull heavy creatures here as they are in that island, 

 where I first became acquainted with them. 



C. — Here is a large two-winged fly, crawling among the 

 grass, which appears almost helpless and unable to use its 

 wings : what is it ? 



F. — It is Coenomyia Pallida : I took one on the 13th of 

 June, 1836, and another on the very same day the next 

 year ; this makes the third. They were all amongst the 

 grass : one of them was in the act of emerging from the pupa 

 when I took it : I have the pupa-skin still ; it is large, and 

 the hind segments have rings of spines ; its colour is chestnut 

 brown, and it much resembles that of a large moth. I have 

 no doubt it is subterraneous in the pupa state. They all ap-
