534 LÉPIDOPTÉROLOGIE COMPAREE 



En dehors des indications que nous \'enons d'exposer ci-dessus, 

 nous avons encore trouvé, dans la collection de M. Charles 

 Oberthùr, deux formes du phylum cronidien, qui ne sont réfé- 

 rables ni au type Cronis de Cramer ni à aucune des morphes 

 Liitca ou Straudi; il nous parait donc indispensable de décrire, 

 au moins succinctement, toutes ces morphes nouvelles, sur les-

Some years since Mr. William Grey, of Albany, called my 

 attention to a most beautiful Casinia of which he has raised 

 both cf and g from the roots of an orchid in the hot-house of 

 Erastus Corning, esq., of Albany, and vvas so good as to furnish 

 me with an excellent drawing of the cf insect, as well as to allow 

 me a sight of the spécimens, from which I made at the time a 

 tull description, intended for publication in « Papilio )>. By 

 some means, however, my notes were mislaid and hâve only now 

 been recovered. I hasten, therefore, to place on record the facts 

 with référence to the species, and if thèse lines should reach the 

 growers of orchids or liliaceous plants, to beg them to look care- 

 fully in their plant-houses for any such strange visitors as the 

 présent. The larvae of the Castnias and those of the allied genus 

 Synenion are internai feeders, and are found in the stems or 

 roots of plants belonging to the natural orders Broméliacées, 

 Iridaceœ, Liliaceœ, Amaryllidacece, and Orchidaceœ. The pupa, 

 like that of Cossus, and Hepialus, is furnished with a séries of 

 small hooked spines on the segments of the abdomen, and when
