318 Captain T. Hutton’s Characters of 
produce of the two sections that are common to both, that the 
differences observable can be regarded only as specific and not 
generic; and although the food of the wild species differs in some 
instances from that of the domesticated races, yet in every case 
the trees are found to belong to the same family, and to be closely 
allied to the mulberry. 
I consequently feel inclined to reject the Genus Theophila, 
which Mr. F. Moore (see Trans. Ent, Soc., 3rd Series, 1. 315) 
proposes to establish for the reception of the wild species ; more 
especially since it is very doubtful whether one at least of these 
could stand under either Bombyx or Theophila, while as regards 
B. subnotata of Singapore, we know nothing of the larva, and 
therefore cannot say whether or not it exhibits the spines and 
other characteristics of the known wild larve; and the same may 
be said of B. religiose. 
It is this eagerness on the part of European systematists to 
give names to the species contained in the Noah’s arks over 
which they preside, that leads to so much positive confusion as to 
what is, and what is not, a species,—a remark well illustrated by 
the late creation of an Antherea under the specific name of 
Mezankooria (see Trans. Ent. Soc., 3rd Series, i. 318), which 
name is applied in Assam, by the native sericulturists, to distin- 
guish the silk of the Mooga (Antherea Assama), when fed upon 
the tree called Addakoory, from that produced by it when fed 
upon other trees. A very similar mistake, at which the working 
naturalist may, without offence, be permitted to smile, was 
recently made by a French savant of some repute, who applied to 
me for information regarding certain alleged species of Tussur 
moths, known in India as Antherea Teriah, Anth. Dabrah, Anth. 
Mooga, and several more, these being, not the names of insects, but 
technical terms applied by the native cultivators of Beerbhoom to 
particular qualities of cocoons of Antherea Paphia, which are 
assorted according to size, colour, &c., under these various titles. 
It would appear that while one school is labouring hard to 
prove that all organized beings are the descendants of ‘ one 
primordial type,” others are equally bent on proving that each 
species is sui generis, and entitled to stand alone.

This species, which feeds on the wild indigenous mulberry tree 
of the North Western Himalaya, is apparently confined to the
