In the determination of these stirpes T have availed myself, next to my own mate- 

 rials, of the families of the Vienna Catalogue, and the arrangement of the Lepidoptera 

 Bombyciformia made by Schrank in the second part of his Fauna Boica. The genera 

 here referred to have been established chiefly according to the larvae. Several of 

 them are of a very comprehensive nature, and will, in future, require subdivision : 

 but the names can always with propriety be applied to the families or sections. 

 They are judiciously chosen and highly descriptive, and should not unnecessarily 

 be supplanted by others taken from the perfect insect, as has been done, in various 

 cases, by Ochsenheimer. 



In the two remaining tribes, the subdivisions which I am enabled to propose are 

 still less determinate than in the Sphingidas and Bombycidge. I shall therefore, at 

 present, give only a preliminary indication of the most prominent types of form, 

 which I have observed in the Javanese series of metamorphosis ; these I shall illus- 

 trate by a comparison with the families of the Vienna Catalogue : a more detailed 

 analysis both of the metamorphosis and of the perfect insect is required for limiting 

 the stirpes, and for indicating their relative disposition, according to the affinities 

 of the subjects which compose them. 



In the Noctuid^, a term which I employ in a more extensive sense than is 

 usually done, I shall exhibit, as the type of one of the stirpes, the following form : 

 a larva cylindrical, smooth and naked, always obtuse behind, with a termination 

 either abrupt, or prominent and rounded. In some of the minor subdivisions, there 

 is, on one of the last segments of the body, an acute prominence with a broad base,
