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 

 pupae, 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 5th, of 

 this year, I was fortunate enough to find two of the larvae. 

 They were feeding on a rose-tree, between Tilbury and 

 Southend, just off the Thames marshes. I would add to the 

 description of the larvae, 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 larvae were full fed on July 10th and 15lh, 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. — R. W. Bowyer ; Haileyhury College^ near Hert- 

 ford. 



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. I 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 brood. — As you are interested in the 

 life of my Caja (Entom. v, 425), I have much pleasure in 

 telling you the large larvae 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 3x^^ inches. Three which came out in Noveuiber 

 1 have left in the feeding-cage, to see if they will hybernate
