these same plants that this aphis attracted the particular notice of the 
Bavarian naturalist Selirank, seventy years ago. The stalks of this 
■weed and the under side of its leaves may frequently be seen toward 
the close of the summer, coated over and black with these lice ; ants 
also, being usually present with them. The turnip too, is sometimes 
attacked and greatly injured by them. The statement of Mr. Lister, 
that in 1854, hundreds of acres of turnips, in Yorkshire, England, 
were almost totally ruined by them, has been given on a previous 
page. 
In the order Rcbiace^e, the bedstraw or cleavers, Galium Aparine 
and other species, is sometimes seen with flocks of these black lice 
crowded together in places upon the slender stems. Many years ago, 
upon the sweet, liquorice-flavored leaves of the Galium. Circcezans , 
I met with an interesting aphis, an account of which may appropri¬ 
ately be introduced in this connection. It occupied the under side 
of the leaves, and by its punctures it caused each side of the leaf to 
turn backward, until it became doubled together, resembling a pod, 
with tire aphides inclosed inside, as if to represent the seeds in those 
pods. This was in the middle of June. Later in the season, when 
the leaves became older and more firm and rigid they, perhaps, will 
cease to double together in this manner. The pupae were but four- 
hundreths of an inch in length, of a dirty, yellowish-white color, 
with the wing-scales, the honey-tubes and the feet black. The 
winged lice were slightly over one-tenth of an inch in length, and 
black with the abdomen bright grass-green, the legs pale, with the 
feet and honey-tubes black. I had ticketed these specimens Aphis 
Oircezandis, a name which the species may appropriately retain, 
should further researches show it to be undescribed. From my notes 
taken at the time I met with this insect and from a re-examination 
of the specimens of it in my cabinet I have drawn up the following 
description : 
'Aphis Ciraezandis, winged female. — Length 0.12 to the end of the wings; head 
and thorax black ; abdomen grass-green; honey-tubes black, short, equaling but 
half the distance from them to the tip. Legs pallid; feet black; knees, at least the 
hind pair, dusky. Wings hyaline; stigma opake, salt-white; veins dark-brown, rib- 
vein white, third vein nbortive at base a very short distance. 
Wing veins .— Second vein slightly curved, twice as distant from the first vein at tip 
as at base, base slightly nearer the first vein than the third, tip about a third farther 
from the first vein than from the third. Third vein nearly or quite a fourth farther 
from the second vein at tip than at base, tip slightly more distant from the second 
vein than from the first fork. First fork at tip thrice as far from the third vein as 
from the second fork. Second fork very short, its tip much nearer the first fork than
