while the latter is split both down the back and along the under 
side to the end of the thorax. Moreover when the moth escapes 
from the pupa-skin, the latter is left with the head and thorax pro- 
jecting out of the end of the cocoon. 
As regards its imaginal or adult characters it is also intermediate 
between the two families mentioned. In the short stout body and 
short broad wings it has the habit of a Limacodes, rather than of 
such Liparid genera as Porthesia, etc. 
In the shape of the antennz and palpi it is about as near the 
Liparidee as the Cochliopodide. 
In respect to the denuded head, Lagoa is much more like Euclea 
than the Liparide. The clypeusis rather long and narrow, similar 
in shape to that of Euclea, though rather narrower, and is thus 
more like that of the Cochliopodidz than that of the Liparidz, rep- 
resented by Orgyia and the European Porthesta chrysorrhea, whose 
denuded heads [ have examined. The epicranium and occiput 
taken together (on the median line of the body) are about one-third 
as long as the entire clypeus. 
As regards the venation, Lagoa is decidedly nearer Euclea and 
other Cochliopodids than the Liparidee (I have examined the vena- 
tion of Orgyia and Parorgyia). Lagoa has the same wide costal 
region of the fore wings as in Euclea, that of the Liparidz being 
very narrow ; the five branches of the subcostal vein are thrown off 
in nearly the same manner as those of Euclea and Limacodes. ‘The 
discal veins and origin of the independent (sixth subcostal) are 
almost precisely as in Euclea, and the four branches of the median 
vein are also similar in their mode of origin, and unlike those of 
Orgyia and Parorgyia. 
In the hind wings, as in the Cochliopodide, there are ten veins, 
in the Liparidze only nine; there are but two branches of. the sub- 
costal vein; the third branch being detached, so that there are two 
independent veins, one arising from the anterior, and the other 
from the posterior discal vein. In the Liparidz mentioned there 
is no independent vein at all. The four median veinlets have the 
same peculiarities in their mode of origin as in Cochliopodids and 
the same differences from the Liparide. 
To sum up: in the superficial characters, of the imago, and in 
having in the larva abdominal legs, Lagoa resembles the Liparide, 
but in all its essential characters, those of the egg, larva, pupa and 
imago, it belongs with the Cochliopodidz, except in the matter of
