328 ANCHYLOPERA MITTERBAOHERIANA. 



Anchylopera MITTERBACHERIANA. 

 Plate CLXI, fig. 7. 



On the 14th of October, 1876, I received from Mr. 

 Wm. Jeffrey several oak leaves, the upper surface of 

 each leaf folded together longitudinally and the edges 

 of the leaf spun closely together from one end to the 

 other, each leaf being tenanted by a larva. I kept 

 two for myself and returned the others. 



On opening one I found the larva within it to be 

 feeding on the green cuticle of the surface enclosed 

 between the veins of the leaf, and an accumulation of 

 frass at one end. The silk which had united the 

 edges of the leaf was quite white. 



The larva was half an inch in length, with the head 

 small and the second segment, into which the head is 

 partially retracted, larger ; this second segment is quite 

 as long as any of the others, which are subdivided by 

 wrinkles into three portions, the greatest portion in 

 front. The tubercular warts are large, raised and 

 transversely oval ; the colour of these warts is a flesh- 

 colour, and they are glistening, and each with a very 

 fine and longish hair. 



The ground colour of the back is an olive or 

 ochreous-green becoming gradually on the side and 

 belly olive yellow. The head and second segment are 

 ochreous and glistening; the skin elsewhere is soft 

 but without gloss. The head has black marks on the 

 crown of each lobe, and the second segment has four 

 small black dots behind, and a larger curved blotch on 

 each side of them. The body tapers considerably 

 behind towards the anal segment, which is very 

 narrow ; the anal legs are close together and pro- 

 jecting behind ; the ventral pairs are rather short and 

 much beneath the body; the spiracles are small and 

 black. (William Buckler, October, 1876; Note Book 

 III, 156.)
