Head, thoracic iobes, antennz, nectaries, tibie, and femora points 
black. All the rest of the body green. Abdomen with four round 
black spots on each side of the carina and several obscure marks 
down the dorsum. ITyes red. Cubitus and wing insertions bright 
yellow, other veins black. Stigma greyish. Tail yellow. Wholly 
green on the under side. Some specimens are of a redder shade 
than the rest. 
S. fragarié is likewise much like S. rose, but it has no crescentic 
spots near the nectaries.”’ 
Siphonophora minor, n. s. 
‘This species was first noticed June 1, 1883, in considerable num- 
bers on the under sides of strawberry leaves at Normal, Ill. The 
plants infested were stragglers, which had grown up thickly in the 
shade of some rows of soft maple trees. / The lice were young, 
and no winged forms were seen until autumn. For the purpose of 
securing unquestionably authentic specimens of the mature forms, 
a number of these infested plants were transferred, with the lice 
upon them, to a breeding cage in the Laboratory, where they were 
kept alive all summer, the lee multiplying freely, although not at 
any extraordinary rate. They attached themselves both to the 
petiole and to the under side of the leaf, but, reared in the shade 
and on unthrifty plants, they did not become numerous enough to 
cause the leaves to curl. They were carefully examined, from time 
to time, in the expectation that winged females would make their 
appearance; but, although wingless viviparous females, and even 
pup, occurred as early as July, the first winged examples emerged 
October 6. From this time forward this form was common in the 
cage until the plants were allowed to die out, some time in Novem- 
ber. Wingless individuals also continued to develop on the plants 
in the open air, and did not differ in any way from those reared in 
confinement. 
Wingless viviparous female. This plant-louse is exceptionally 
small and of delicate appearance, even adult ova-bearing females 
being almost white. The eyes and antenne are black (except the 
two short basal joints of the latter, which are pale), and the tibie 
and tarsi are dusky; but otherwise the entire body and all its ap- 
pendages are a uniform, very pale greenish yellow. It is only in 
the older specimens that even the antennez and legs are dark. 
The body is more slender than usual, and the lees and antenne 
are exceptionally long. The length to the base of the tail is 1.1 mm. 
(.044 inch), and the greatest breadth .52 mm. (.024 inch). The 
antenne are more than half as long again as the body (1.8 mm.), 
the 6th joint being much the longest, equaling the 3d and 4th taken
