color the whole of the under side soon participates. Two dusky 
spot8 next begin to come out on the hind edge of the thorax, and 
two smaller ones appear on the second segment of the abdomen, 
followed by a few other spots elsewhere, which it is scarcely ne¬ 
cessary to particularize. These smoky colors continue to deepen, 
becoming almost black where they were first perceived, when, 
last of all, in about two hours after the larva skin is thrown off, 
the sheaths of the wing covers are seen to acquire a dusky dot 
near their centre, which becomes more obvious as the same hue 
begins to be seen on the tips and along the margin of these mem¬ 
bers. On longer exposure to the air and light, all these spots 
change to pure black, the rich yellow ground color in the mean 
time fading to obscure pale yellow, somewhat brighter upon the 
wing covers. 
I notice some larvm are suspended which are not grown to their 
full size, and which do not cast off their skins to assume their 
pupa form. These, I suspect, are infested with internal parasites. 
The insect remains suspended and at rest in its pupa state ten 
days, in the instances I have observed. Its dry outer skin, or 
shell, then again cracks asunder at the anterior end ot its back, 
and the perfect insect withdraws itself therefrom. It is at first 
a soft, turgid, unwieldly mass, overloaded with fluids. For these 
fluids to evaporate, it remains stationary for several hours, cling¬ 
ing to the outside of its pupa skin, or to the leaf or stalk where 
this skin is fastened. It stands with its wings projected out from 
under the ends of its wing covers, resembling flattened tail-like 
appendages almost as long as the body, light yellow and opake, 
or but feebly translucent. The wing covers are at first of a rich 
citron-yellow color, and wholly destitute of any discoloration to 
indicate the black spots which belong to them, although the tho¬ 
rax has .its black color and white margin well developed. T.he. 
spots of the wing covers are gradually brought out as in the pupa, 
by exposure to the air and light, those of the hind part being fii st 
to appear by a slight discoloration or smokiness, and the common 
spot at the scutel being the last one that is completed, this re¬ 
maining divided by pale lines upon the suture after its outei pait 
has become dark colored and quite distinct. As soon as its 
several parts have acquired a sufficienl degree ot firmness and 
consistency by the evaporation of their superabundant juices,
