452 THE ENTOMOLOGIST. 
Chelonia caja bred from eggs laid this year.—This day, 
November 8th, I have seen a specimen of C. caja alive, from 
pupe, the eggs laid this year. I have had also a larva of 
B. Rubi turn to pupa without any cocoon whatever. Is not 
this singular? I always thought they hybernated.—W. 
Mann; Bristol. 
Liparis dispar.—The following notes on L. dispar may 
be interesting to Mr. Clifford and others. On July Sth, of 
this year, I was fortunate enough to find two of the larve. 
They were feeding on a rose-tree, between Tilbury and 
Southend, just off the Thames marshes. I would add to the 
description of the larve, as given in Newman’s ‘ British 
Moths,’ that the tubercles on segments 2, 3, 4, 5, 6, are of a 
deep blue colour ; those on 7, 8, 9, 10, 11, 12, of a blood-red. 
The larvze were full fed on July 10th and 15th, and then spun 
very slight webs. They fed on whitethorn or rose, with 
equal readiness. A perfect insect appeared on July 28th, a 
very fine male; and a female on August 5th: this latter was 
unfortunately a cripple. Both insects were of the typical 
form.—h. W. Bowyer; Haileybury College, near Hert- 
Jord. 
Entomological Pins.—A correspondent regrets the perish- 
able condition of the ordinary entomological pin, when acted 
upon by the corrosive matter formed in the bodies of many 
preserved insects. 1 would suggest pins made of aluminium, 
or aluminium bronze, which probably will resist this acid 
reaction. At any rate, should any compound of aluminium 
be formed it will be colourless, and, therefore, will not 
disfigure natural-history specimens with verdigris spots. 
Some of our collectors, who live in the manufacturing 
districts, may have it in their power to turn out pins from 
aluminium wire. By so doing, they will confer a benefit on 
the entomological public.—G@. B. Buckton. 
Chelonia caja ; second byood.—As you are interested in the 
life of my Caja (Entom. v. 425), I have much pleasure in 
telling you the large larve began to spin on the 8th 
September. Some came out the middle of October; and 
they continued to emerge until the first week in November. 
Some were very fine; the largest in expanse of wing - 
measuring 37%, inches. Three which came out in November 
I have left in the feeding-cage, to see if they will hybernate
