490 Mr. John Curtis's Note on his Paper printed at Page 249. 



maggot (fig. 2.), which I joined together, and certainly there are no indica- 

 tions of its being the larva of a Tenthredo ; the head is not large enough, and 

 I could not discover any feet, not even the pectoral. It is therefore more 

 likely to be a larva of the family Ichneumonidce. Great numbers of the curious 

 spines which clothe the caterpillar of Saturnia Pavonia-minor fell out of the 

 cocoon, as well as atoms of exuviae apparently ; but I conjecture, from their 

 imperfect state, that they had remained for many months exposed to the 

 changes of the seasons. 



The cells most analogous to these are some formed by the Microgaster 

 alvearius (Curtis's Brit. Ent. fol. & pi. 321), which are as regular as a honey- 

 comb ; and I find from the following notice, that the pupse of the Eggar- 

 moths are similarly infested. At a meeting of the Entomological Society, 

 Dr. Calvert " exhibited a cocoon, apparently of one of the Eggar-moths, the 

 interior of which was occupied by a great number of the minute cocoons of 

 one of the Ichneumonides adsciti closely arranged with great regularity." (Ent. 

 Trans, vol. iii. p. xxxv.)
