Insects. 5385 



Phragmatobia lubricipeda and Menthrasti. Common. Spun up 

 in loose rubbish collected about the roots of various trees. October, 

 &c. 



„ mendica. Rarely. Under moss on trees bordering 



damp ditches. Gloucestershire. October, &c. 



Liparis monacha. This singular chrysalis may be found by 

 examining the trunks of oaks, in the crevices of the bark of which tree 

 it spins up. End of July. 



Orgyia pudibunda. The conspicuous yellow cocoon of this species 

 is easily detected among loose rubbish collected about the roots of 

 trees ; sometimes under loose bark. The larva is polyphagous, and 

 consequently the pupa may be found at various trees. October, &c. 



„ Coryli. Very plentifully under moss on beech : generally at 

 the roots, and not on the trunk. October, &c. Bucks. 



Eriogaster lanestris. I was much surprised at finding two pupae of 

 this pretty insect, the other day, at the roots of an elm : I thought it 

 was exclusively a hawthorn-feeder, but there was no hawthorn at all 

 near at hand. October, &c. 



Trichiura Crataegi. The compact egg-shaped cocoon of this species 

 I have once or twice met with at the roots of poplar, the larva having 

 probably wandered from some neighbouring hawthorn. July. 



Pcecilocampa Populi. This insect is found in various situations, 

 and on various trees, — ash, poplar, &c. : sometimes it will be found 

 firmly glued to the inside of a piece of loose bark or to the tree itself; 

 at others spun up tightly among decayed leaves, dead grass, &c. It 

 ought to be among the early captures of the pupa digger, as it is 

 common, and not difficult to find. The cocoon is black. August and 

 September. 



Platypteryx falcula. Where birch is common examine the leaves 

 joined together, and you will not unfrequently find the pupa of this 

 species. June, and again in September, &c. 



„ unguicula. Substituting beech for birch, the same 



remarks apply to this as to the preceding. 



Cerura furcula. Under bark and on trunks of willow, occasionally. 

 September, &c. 



„ bifida. Occasionally on trunks and under bark of poplars. 

 September, &c. 



„ vinula. On trunks of poplar and willow. September, &c. 



In regard to the two first of these insects, the best way, I think, to 

 find them is to draw the finger slowly down the trunk, and carefully 

 to examine the line thus formed and about an inch on each side of it;
