the fourth vein. Fourth vein curved, its tip a third nearer to the second fork than to 
the tip of the rib vein. 
Variety a. Second vein equidistant between the first vein and the third at base and 
also at tip. 
Variety b. Third vein at tip equidistant between the second vein and the first fork. 
Second fork at tip equidistant between the first fork and the fourth vein. 
Variety c. Third vein emitting a branch, half way from the base of the first fork 
to the tip, the branch curved, approaching the first fork and then receding from it, 
not attaining the margin. 
Iu the order Umbellifer.e, the Eryngium campestre is said by 
Fonscolomb to be attached by the bean aphis. The parsnip, Mr. 
Curtis states, was attacked in July 1847, in the same manner as the 
beet, noticed above; the under side of the leaves were crowded and 
black with the winged lice. But, as they all perished within a few 
days, none of the plants were killed by them. 
In the order Convolvulace^e, we are informed by Mr. Curtis that 
the underside of the leaves of the convolvuli became covered with 
these lice, at the time of their visitation in 1847. 
In the order Solanace^e, on the leaves and young shoots of the 
potato, this aphis settles itself, in toe force at times, Mr. Curtis says; 
but lie has never seen it on this plant in such numbers as to injure 
the produce. 
In the order Compositad, the dahlia is liable to have its young shoots 
invaded and the flower buds blasted by this insect. Among the plants 
mentioned by Fonscolomb (Annales Soc. Entom. de France, vol. 10, 
page 163), as being the residence of this aphis are the following 
members of this order: the burdock, the Canada thistle, the large 
common thistle, the star thistle Centaurea Calcitrapa, the yellow 
vegetable oyster Tragopogon pratense , the chamomile and marigold. 
He also thinks this is the species which he has observed upon the 
young shoots of the succory. 
In the order Gramine.-e, Mr. Walker describes a variety of this 
aphis which occurs upon the manna grass Poa ( Glyceria) Jluitans, 
common in the wet grounds of Europe and this country. 
Finally, in the order Celastrace/e, an aphis has infested a thrifty 
young burning bush or spindle tree, Euonyrnus Americanus, growing 
in my yard, whereby I have enjoyed a most favorable opportunity for 
studying it and observing its habits the whole season through. It is 
clearly the species named Aphis Euonymi, by Fabrieius, which lie 
obtained upon the Euonyrnus Europceus, a small tree or shrub inti¬ 
mately related to our American spindle trees. And it is also the 
Aphis Rumicis, the insect now under consideration. I speak with
