264 Dr. T. A. Chapman on a lepidopterous 
of the whole pupa-case after the moth has emerged, as 
well as the splitting for dehiscence being only one dorsal 
slit, are quite parallel with larval ecdysis, not with pupal, 
anywhere else in Lepidoptera to which my knowledge 
extends. The moth itself also, as regards much of the 
integument, especially the chitinous plates of the abdo- 
men, is white and colourless till after emergence. In 
all these respects the analogy is much closer with 
Coleoptera than with the mass of Lepidoptera. 
I must call attention to an error of nomenclature into 
which I have fallen, having applied the names Microp- 
teryx and EHriocephala in precisely the reverse way to 
their proper meanings. Micropteryx is the name for the 
subject of these remarks—purpurella, and the purpurella 
group, the ‘‘ Higher” Micropteryges of Walter and others 
—the tree-feeders, leaf-miners, and leaf-piercers—jaw- 
less as imagines, but not as pups. LHriocephala is the 
name for the Calthella group, the ‘Lower’? Microp- 
teryges of Walter—the pollen eaters, with simple ovi- 
positors and active jaws (as imagines) ; the larve moss- 
feeders, with twenty-two legs. The names are so applied 
in Stainton’s monograph. 
I may here call attention to an error into which I fell 
in my recent paper on pupa, viz., as to the pupe of 
Pyrales. I stated these to be without maxillary palpi; 
I find, however, that they exist in not a few Pyrale 
pup ; and further, that of the non-Macro section of the. 
Obtecte most groups have one or more characters that 
are more developed in and more diagnostic of the In- 
complete ; such as the possession of maxillary palpi, of 
a pre-prothoracic element, and even in having the glazed 
eye attached to this on dehiscence in rare instances. 
I am indebted to my friends Mr. Bankes and Mr. Tutt 
for the information that the pupa of Hndromis versicolor 
emerges from its cocoon before the escape of the moth. 
As Mr. Bankes hopes to further investigate this curious 
instance of an ‘“‘ Incomplete” habit resorted to by a 
Macro, I will content myself with this mere mention of 
the habit. 
I notice also that Scudder states that the pups of the 
Sphingid genus Macrosila emerge from the earth for the 
escape of the moth, using for the purpose certain flanges 
in the spiracular region. These exceptions (by rever- 
sion ?) require a modification of my statement that no
