Sipiionophora viTicoL4. Tlios. The Grape-inhabiting Aphis. 
In the latter part of June, Prof. French sent me some leaves, of 
Clinton grape-vines infested by this species, which he found at Irving¬ 
ton, in the southern part of this state. The next day I was fortunate 
enough to find the same species on one of my own vines. Xot numer¬ 
ous, Tt is true, but in sufficient numbers with a favorable season to do 
the vines considerable injury. They were found on the young and 
tender leaves and stems near the ends of the young branches. 
Whether this is the A vitis of Scopoli or not I am unable to say, as 
x have not seen the description of that species. 
Wingless-females .—Strongly ovate in shape, broad behind, and about 
.08 of an inch long. Of a dusky-brown color, somewhat paler in 
front. Antennae of the usual form in this genus, but scarcely as long 
as the body. Honey-tubes very long, slightly curved and slightly en¬ 
larged at the base, cylindrical and fully one-fourth ot the length of 
the body. Legs rather long but not to the same degree as in 8. 
ruclbeckioe. 
Honey-tubes, legs and antennae black except that there appears 
usually to be a broad, pale annulus on the antennae near the base, and m 
many specimens there are also several pale rings. 1 he tibiae of the 
front legs have the upper half pale, fail distinct. 
Winged-female . — Very similar in appearance to the wingless, some¬ 
what slenderer; front parts darker, the head and central paits of the 
thorax dark brown. The second discoidal vein more than usually dis¬ 
tant from the third; stigma dusky or brown, elongate, sides paiallel, 
pointed at the tip. Length of body same as wingless. 
The following notes in reference to this species were kindly fur¬ 
nished me by Prof. French. 
u About the 25th of June they first began to appear on the ends ot 
the twigs of the Clinton grape-vines, working at fiist only a few inches 
down from the end. They spread rather rapidly over the twigs, so 
that in the course of two or three days they were on a dozen or more. 
By this time the larvie of a Syrphus and a Chrysopa had found them 
and were at work upon them. By July 10th the lice had spiead oa ei 
the vines along one side of a walk, which is boideied on both suits 
by a mixture of Clintons and Concords, yet working on the Clintons 
only. They appeared to work mostly on those twigs in the shade of 
some neighboring peach trees. July 14tli a fuithei examination showed 
that more twigs were infested than before, some twigs w^ere covered 
as far down as twelve or fifteen inches from the tips.” 
During the past season (1878) I had an opportunity of observing 
this species somewhat carefully, I found almost every colony ruthlessly 
attacked by a species of Apliidius, which in a short time destroyed all 
on my vines.
