willow, which were colleclcd in February, and the iniagos 

 emerged in June. [Of course these are not gall-makers.] 



No. 2 [Eurytoma gracilis, a parasite] is from a gall formed 

 on the midrib of an oak-leaf, which gave the leaf a very 

 crumpled appearance. Collected August 3rd ; imago out 

 August 10th 



No. 4 [Urophora Cardni, a dipteron, and Eurytoma plu- 

 mata, its parasite] are from the large globular galls of the 

 star-lhistle, which were collected in July. The large dipteron 

 emerged from them July 27th, and the six Hymenoptera on 

 August 13th. One of them has deep red eyes, and both 

 species form egg-shaped cocoons in the interior of the gall, 

 which is very dense when dry, but a passage is always left for 

 the exit of each of the imagos at the crown. 



No. 5 [One of the Cynipida^.] were bred from a curious 

 elongated gall, formed in the flower-stalk of a species of 

 knapweed (gall enclosed).: it was gathered in November, and 

 the imagos emerged June 20th. They appear to be scarce 

 here, as 1 could only find two. 



No. 6 [Cynips Kollari], from large globular woody galls of 

 the oak. 



No. 7 [Cynips Quercus-folii], from soft cherry -like galls of 

 the oak-leaf, which emerged December 20th. — Henry Mon- 

 creaff ; Southsea.

Diurnea fayella at Leeds. — This species occurred this 

 spring in great profusion in a wood adjoining my house. The 

 male is a very sluggish insect, and, though provided with 

 ample wings, I do not remember to have seen them used 

 voluntarily. All day long they sat motionless on the trees, 

 and were there at night when I went round with a lantern : if 

 removed and thrown up into the air, they almost invariably 

 flew to the nearest tree, and at once settled down again to 

 their slumbers in a crevice of the bark. I was struck with 

 the great apparent disparity in the numbers of the sexes : of 

 the male dozens might be seen on the trunk of almost every 

 oak, whilst of the semi-apterous female I only saw about a 

 score altogether. The larva of D. fagella, when full fed, 

 spins up between united or folded leaves : when these fall 

 they must often be carried by the wind far from the tree
