398 MODERN CLASSIFICATION OF INSECTS. 
ploea, Vanessa, Argynnis, &c.); 4. Thysanuriform Stirps (Apatura, 
Morpho, Hipparchia, &c.); and, 5. Anopluriform Stirps (Erycina, 
Hesperia, &c.). The stirps are related iter se by means of aberrant 
genera, whereby not only the progression of affinities is maintained, 
but the circle of the diurnal Lepidoptera, completed by means of 
Barbicornis (my jig. 101. 5.), which is supposed to connect the 
Papilionides and the Hesperides. 
The Sphingide are also supposed to exhibit five types of form in 
the larve. These are exemplified by Zygeena, Macroglossa, Sme- 
rinthus, Acherontia, and Sphinx; A®geria and its allies being sup- 
posed to possess a different metamorphosis, are omitted, being con- 
sidered, at least in part, to enter into the next tribe; Zygzena, and 
its allies, ought also to have been rejected from the Sphingide, with 
which they exhibit but little relationship. 
The Bombycide, also, although admitted to be less generally known 
in their early states, exhibit five prominent forms : — 1. Fasciculate, 
typified by Laria and Arctia; 2. Verticillate, typical genera Lima- 
codes and Saturnia; 3. Pilose, typical genus Lasiocampa; 4. Ligni- 
vore, typical genera Pygzra, Cossus, and Hepialus ; 5. Cuspidatee, 
typical genera Cerura, Notodonta. 
The five stirpes of the Noctuide are also formed, although only 
provisionally, from the larvee:—1. Nudz, typical genera Agrotis, 
Mamestra, Polia, &c. (which are considered as typical of the tribe) ; 
2. Fusiformes, typical genus Lithosia, with which, possibly, many of 
the Tinez may also be associated ; 3. Fasciatee ; 4. Ciliatee, typical ge- 
nera Catocala and Abrostola; 5. Semigeometre, type Plusia. 
The remaining tribe, Phalznidz, also exhibits, among the larve of 
the insects which compose it, five types of form, the precise limits 
of which require more detailed investigation. They are :— 1. Semi- 
noctuales, Phal. Margaritaria, &c.; 2. Geometrz, or true loopers ; 
3. Pyralidee (containing in the Weiner Verzeichniss two families, an- 
swering to Herminia and Botys; 4. Tortrices; 5. Tinez. 
The arrangement of the last four of these tribes given above is 
admitted to be but a provisional sketch, of which the outlines require 
to be filled up in future numbers of the work. It is consequently to 
be regretted that only two parts, comprising but a portion of the 
diurnal Lepidoptera, have hitherto been published. Dr. Horsfield 
endeavours to complete the Lepidopterous circle by means of Hes- 
peria, which in its structural characters and tortriciform larvee (which
