APHIS. PARENTHESIS COCCINELLA. 
There are but two varieties of this species which appear 
sufficiently remarkable to be worthy of notice. 
Variety a, interrupt a. The band on the wing covers with its ends nearly or quite broken off 
from the middle portion. I have never seen a specimen with the ends of the 
bands perfectly separated. Those in which they are partially broken off are not 
rare. 
by transverso-guttata, Faldcrman. A small black dot on the wing-covers nc?r 
their outer margin, placed at a third of the distance from the base to the tip. 
Common. Mulsant regards this as the normal state of this species. Of twenty 
specimens at present under my eye only six have this dot, and a seventh one 
* shows it on the left wing cover only. 
This species occurs in New York and other Northern States, in 
Canada, Greenland, and Russian America, and has also been dis¬ 
covered in Irkutsk and other provinces of Siberia. 
The Parenthesis Coccinella. Adonia parenthesis, Say. 
A smaller and more oblong species than the two foregoing ones, 
and running with much more briskness, began to appear in the 
grain fields as the crops were ripening, and rapidly increased, so 
that at harvest time it had become much more numerous than 
the Nine-marked Coccinella, at least in fields of oats. This is 
another of our common species, which begins to be seen abroad 
on the first warm days in April, having come out from its winter 
retreats under stones and sticks lying on the ground. It is met 
with through the whole summer, on rushes and grass in wet 
places, and in other situations, indicating it to have an appetite 
for a greater variety of plant-lice than the Nine-marked Cocci¬ 
nella has. 
Its eggs are 0.035 long, oval, soft, shining, pale orange, and 
are placed irregularly together in little masses of three or more, 
slightly adhering to each other and to the heads and stems of the 
grain on which they are scattered. 
Its larvae are so similar to those of the Nine-spotted Coccinella 
that I have overlooked them, supposing them from their smaller 
size to be the same species in its younger state. 
To change to a pupa it usually places itself upon some small 
weed where it will be nearer the ground than the situations which 
the Nine-marked Coccinella seems to prefer. The dead stalks of 
sorrel are much resorted to by it, on which it suspends itself to 
the slender thread-like branches, from among the dry brown seeds 
which are attached thereto. Its black larva-skin beset with
