6 CYMATOPHORA OCULARIS. 



was composed first of an open network of coarse silk 

 of a deep brownish-red colour, the meshes of which 

 were at first, when wet, quite regular and symmetrical 

 in some parts, and very flexible (at which time the 

 pale skin of the larva could be seen through them) ; 

 but these soon contracted, and were enveloped by the 

 closing up of the leafy surroundings. 



When the cocoon was opened and divested of its 

 leaves, it was a remarkable specimen of reticulation ; 

 the outer foundation oval in form, three-fourths of an 

 inch long, made with very s-tout threads, leaving large 

 meshes of oval, pear-like, and angular shapes, filled 

 with a yery tangled layer of much finer silk, remind- 

 ing one of the smaller vessels of a skeletonised leaf. 



The pupa was five- eighths of an inch in length, 

 thick, and dumpy in form and proportiou, the surface 

 roughened, except in the abdominal divisions, by 

 minute pits, and on the wing-covers and thorax by 

 corrugations ; the abdomen ending with two converg- 

 ing spines, their tops recurved, crossing each other, 

 and a few recurved short bristles round the abdominal 

 tip ; the colour black, the abdominal divisions dark 

 purplish dull red, the other parts a trifling glistening.

Plate LV, fig. 5. 



A larva on oak was received from Mr. G. 0. Bignell, 

 of Plymouth, August 6th, 1875. Length one inch and 

 a quarter, moderately stout, of nearly uniform width, 

 tapering very little on the last four segments, behind 

 the anal segment rounded off ; the head quite as wide as 

 the second segment, the rounded lobes well defined 

 on the crown, broad below at the sides, a little flat- 

 tened in front, the second and third segments rather 

 short.
