340 MODERN CLASSIFICATION OF INSECTS. 
(to which Dr. Horsfield gives the family name Papilionide*), into 
five stirpes, each supposed to be connected with the two adjoining, 
and the terminal to be in like manner allied to the first, so as to form 
a circle; these stirpes being named in accordance with their sup- 
posed analogies with the Ametabolous orders, and following each 
other in the same order as the latter occur in the Hore Entomo- 
logice, p. 390. 392., the Ametabola not only pointing out the natural 
order of various minor subdivisions, but representing many annulose 
forms in their simple elementary state. These analogies, although 
employed by MacLeay, especially with reference to the Coleoptera 
(see ante, vol. i. p. 39.), are much more clearly exemplified in the 
Lepidoptera ; and hence Dr. Horsfield considers that all the various 
forms of the larve of the diurnal Lepidoptera can, without excep- 
tion, be reduced to the five stirpes described below, which are con- 
structed according to the plan of the orders of the Ametabola. 
The first, or VermirorMm stirps, has the larva of an oblong linear 
form, attenuated at both ends; in some cases depressed, or slightly 
convex ; in others cylindrico-gibbous, appearing to consist of numerous 
scuta or shields, distinctly divided by transverse strize, having a small 
retractile head, and very short, scarcely perceptible feet, and is of a 
sluggish appearance. These larve bear a strong analogical resem- 
blance to some of the Vermes (considered by MacLeay as possessing 
the least complicated structure), but having a more apparent analogy 
to the osculant group in the neighbouring circle of the Crustacea, 
which comprehends Oniscus, Armadillo, and Asellus. Dr. Horsfield 
found five varieties of the metamorphoses of this stirps in Java. The 
pupa is obtuse at both ends, particularly at the anterior; is nearly 
smooth, and is vertically suspended in the same manner as in the 
typical stirps; its head upwards, either erect or bending forwards, 
fixed by the tail and girt across the middle. The perfect insect is 
also comparatively simple, the whole of the stirps having been com- 
prised in the lowest rank of the Linnzan arrangement under the 
name of Plebeii rurales, many of which are nevertheless exceedingly 
beautiful. The palpi are slender and of great length, extending in 
* Tt will be seen that the nomenclature of Dr. H. is at variance with that of 
MacLeay ; the latter dividing the order Coleoptera into five primary groups, named 
from their analogical resemblance to the orders of Ametabola; whilst Dr. H. names 
the primary groups as families in ide, and the secondary groups from such analogical 
resemblance,
