654 THE SECRETARY ON THE INSECTARIUM. [JuDC 7, 



Melitcea cinxia. — Imagines of this species were bred from larvae 

 during the mouth ; and perfect insects were on view nearly the whole 

 month through. 



Nemeobius lucina. — Imagines of this species emerged from pupae 

 during the month. 



Heterocera. 



Chelonia caja. — Larvae of this species attained a fine size, and 

 produced large imagines, commencing to emerge at the latter end of 

 the month. 



Chelonia. villica. — The larvae of this species spun up during the 

 early part of the month ; and many fine imagines have been produced 

 during the last ten days of the month. 



Callimorpha dominula. — Larvae and pupae of this species were on 

 exhibition during first half of the month, and imagines during last 

 half. The species fed up well, and produced full-sized imagines. 



Odonestis potatoria. — This species fed very slowly during the 

 month. Cocoons were formed towards the latter end. 



Orgyia gonostigma. — The handsome larvae of this species were 

 exhibited during the earlier part of the month, and some females 

 (apterous) bred and exhibited. 



Lasiocainpa quercifolia. — The larvae of this species fed up well, 

 and produced full-sized cocoons towards the end of the month. 



Saturnia carpini. — Larvae of this species hatched from eggs 

 obtained May 24. Food-plant Plum. 



Bombyx neustria. — A colony of these larvae were obtained small, 

 and have fed up well, many cocoons being in the cage at end of 

 the month. 



Cossiis ligniperda. — A piece of the branch of a willow-tree much 

 bored, and containing larvae of this species, was exhibited from 

 the 28th instant. 



Catoccda fraxini. — The larvae of this species obtained from eggs 

 grew well till they wei'e nearly an inch long, when they refused food 

 and gradually died off. A second batch retained in my studio were 

 then placed in the Insectarium ; and these likewise died. I think 

 they were hatched too early. 



Catocala sponsa. — Young larvae of this species obtained from eggs 

 did not do well, gradually dying off. I retained a few in my studio, 

 and put them iu the Insectarium when an inch long ; and they 

 rapidly fed up, and are nearly full-fed. 



TJropteryx sambucata. — The stick-like larvae of this species were 

 very interesting when visitors could distinguish them from the twigs 

 of hawthorn upon which they were feeding. 



European Rhopalocera. 



Apatura ilia. — Two larvae of this species obtained from Germany. 

 Both are now full-fed and about changing. 



MeJitcEa maturna. — Imagines of this species were bred from larvae 

 sent from Grermany.
