in the pupe of Heterocerous Lepidoptera. 109 
groups usually placed in the Tinee, some of which (like 
the Gelechide) are sufficiently allied to the rest of the 
group to be undoubtedly Pyraloids: others of which 
may be entitled to form groups of the Obtecte of equal 
value with the Macros (proper) and Pyraloids. But 
here I must say that I have not examined enough species 
of each group, or minutely enough, to give more than a 
a very provisional opinion. These groups are the 
Epigraphiide, Hyponomeutide, Plutellide, Gicophoride, 
Argyresthide, Coleophoride, and possibly a few genera 
of doubtful position. 
I have not formed any strong opinion as to the value 
of the remarkable character of many Gelechid pupx, by 
which the movement of the free segments is confined to 
an antero-posterior one only, with something of the 
manner that belongs to the movement of the click- 
beetles. There are several oddities among the Pyrales, 
and this seems hardly a sufficient one to require a dis- 
tinct class. 
Of the Pyraloid families mentioned above, the Hypo- 
nomeutide, Argyresthide, and Coleophoride, seem to be 
those that are most probably of value corresponding to 
the Macros (proper) and Pyraloids, whilst the others 
rather fallin line with the other families of Pyraloids. 
As to this I am by no means confident, but the Coleo- 
phoride, for instance, have a pupa of by no means the 
hard texture of a Macro or Pyraloid, and it is not eylin- 
drical, having on each side of the dorsum a deep hollow 
so that a cross section presents re-entering angles. 
Finally, there is Alucita. 
It is curious that in all these groups, whether they 
be classed as Pyraloids in one group or separately, the 
larve have 16 legs, and complete circles of hooks on 
abdominal prolegs, differing in this way from the Macros 
(proper) where we have groups with 14 and 12 and 10 
legs (missing legs lost), and from the Micros (Incom- 
plete), where variations occur even to an apodal state 
(missing prolegs often (?) never acquired). I think it 
is also true that though nearly all are more or less con- 
cealed feeders, leaf-miners are wanting, or very rare. 
The Micro (Incomplete) pup are more interesting 
than the Macros, in so far that they present much more 
variety. Their incomplete character suggests that they 
are a lower form than the Obtecte, and this is confirmed
