348 Dr. T. A. Chapman’s notes on Micro- Lepidoptera 
inflated or elongated base, carrying an appendage articu- 
lated to it, or several such; but these appendages are 
always simple hair-like or spinous, just as they are in 
testudo after the first skin. 
In the case of Zygena I have failed to detect any 
structures in the young larve I have examined at all 
parallel to these, and must still rely on the structure of 
the egg, the form and habit of the larva, and the very 
primitive form of the pupa, for its alliance with this 
section. 
I have examined the eges of Limacodes testudo, Hetero- 
genea asellus, and Parasa chloris. They are all flat, 
oval, colourless, transparent, with lozenge-shaped net- 
work of cell-structure of the shell, easily seen if examined 
in suitable light and with moderate magnifying power. 
Such eges occur amongst the Micros and in some Pyrales. 
Nothing like them is anywhere met with, so far as I 
know, amongst Macros. 
The pupa also is of evident Micro type. The wing 
and appendage cases are not attached to abdominal seg- 
ments beyond the second. They are not difficult to 
detach, in some species, from each other. The maaille 
are small, but are prolonged outwards, and after pass- 
ing through a narrow neck terminate in a (sometimes 
rather twisted) club between the eyes, antenne, and 
legs. This represents the maxillary palpus, which no- 
where in Macros has any such development. 
Then movement exists in the 38rd and 4th abdominal seg- 
ments and in the g¢ pupa, also in the 7th. Further, the 
larva hes unchanged in the cocoon all winter, and moults 
to pupa in the spring, and the pupa escapes from the 
cocoon for emergence. 
These characters apply to the following species which I 
had alive last spring: Limacodes testudo, Parasa chloris, 
Limacodes scapha, Heterogenea asellus, Hmpretia stimulea, 
and Lagoa crispata. 
I do not know that a detailed description of each 
would carry us much further. ‘They vary in the propor- 
tion of parts, the extent of toothed armature on the back 
of the abdominal segments, and other sculpture. Other 
features that do not so much interest us in the present 
connection are the possession of a beak between the eyes 
(for rupturing the cocoon); the projection backwards 
of the meso-scutellum, so that its sharp apex almost
