bitaceous plants, I would have at once decided that the specimens 
found by Miss Middleton belonged to that species. 
There are other species of Siphonophora that infest cultivated plants 
in Europe, which so far have not been noticed on the same plants in 
this country, but as it is likely an examination will show that they 
are here, l"will mention a few which are most likely to be found. 
Siphonophora tanaceti. Linn. The Tansy Aphis. 
This species feeds on the common Tansy Tanacetum vulgare. 
Winged individuals of a clear brown color, with lighter shades; eyes 
red; legs black, hairy; honey-tubes passing the tip of the abdomen; 
tail distinct, yellow; wings large. Wingless individuals, with the neck, 
hind margin of the prothorax and broad margins of the abdomen, 
yellow. 
Length .07 to .10 inch; to the tips of the wings .19 inch. 
Siphonophora fragarle. Koch. The Strawberry Aphis. 
This species feeds on the strawberry plant, especially the underside 
of the leaves and the stalks of the unripe fruit. A species which I 
presume is identical with this has been occasionally observed on straw¬ 
berry plants in this state, but so far I have been unable to procure 
specimens, and hence give a brief description from Koch’s work. 
Winged female .—General color brownish-yellow, or ocher; the head, 
antennas, thorax and honey-tubes black; a row of black dots along each 
lateral margin of the abdomen, and two larger spots of the same color 
behind the honey-tubes; legs brownish-yellow; tail prominent and yel¬ 
low. Honey-tubes very long, extending beyond the tip of the tail. 
The stigma of the front wings very narrow (as shown in his figure.) 
Wingless female. —Pale dull green or rusty-yellow; the head brown 
or dusky; antennae and honey-tubes black. 
This is a rather large species, the body being from .10 to .12 inch. 
In 1875, Professor Riley received from Mr. W. W. Hopkins, of 
Kansas City, specimens of a plant-louse which was injuring his straw¬ 
berry plants. From a copy of his notes on these specimens, which lie 
very kindly sent me, I learn that they differ from Koch’s description 
in wanting the spots on the sides of the abdomen in the winged fe¬ 
male; and in the head of the wingless female being yellow; yet he 
decides, without serious doubt, that they belong to Koch’s species. He 
names this variety immaculata. 
Siphonophora menth^e. Buckton. 
Wingless viviparous female. —Length of body .08 inch, of antennae 
.10 inch, of honey-tubes .025 inch. 
Long oval, narrow at the head, very broad at the middle of the abdo¬ 
men. Lively green, transparent, and often permitting the eyes of the 
embryos within to appear as red specks. Abdomen usually exhibits 
delicate lines, as if they were sutures of horny plates. Antennae very 
long, slightly olive at their tips. Frontal tubercles very large, and 
slightly gibbous, eyes red. Head, thorax and abdomen, consolidated
