Siphonophora minor , n. s. 
bis species was first noticed June 1, 1888, in considerable num- 
,! cm the under sides of strawberry leaves at Normal, Ill. The 
its infested were stragglers, which had grown up thickly in the 
le of some rows of soft maple trees. The lice were young, 
no winged forms were seen until autumn. For the purpose of 
iring unquestionably authentic specimens of the mature forms, 
amber of these infested plants were transferred, with the lice 
u them, to a breeding cage in the Laboratory, where they were 
; alive all summer, the lice multiplying freely, although not at 
extraordinary rate. They attached themselves both to the 
| ole and to the under side of the leaf, but, reared in the shade 
on unthrifty plants, they did not become numerous enough to 
5e the leaves to curl. They were carefully examined, from time 
ime, in the expectation that winged females would make their 
earance; but, although wingless viviparous females, and even 
ae, occurred as early as July, the first winged examples emerged 
)ber 6. From this time forward this form was common in the 
5 until the plants were allowed to die out, some time in Novem- 
Wingless individuals also continued to develop on the plants 
he open air, and did not differ in any way from those reared in 
[ inement. 
T ingless viviparous female. This plant-louse is exceptionally 
11 and of delicate appearance, even adult ova-bearing females 
g almost white. The eyes and antennae are black (except the 
f short basal joints of the latter, which are pale), and the tibiae 
tarsi are dusky; but otherwise the entire body and all its ap- 
lages are a uniform, very pale greenish yellow. It is only in 
older specimens that even the antennae and legs are dark. 
| ie body is more slender than usual, and the legs and antennae 
exceptionally long. The length to the base of the tail is 1.1 mm. 
1 inch), and the greatest breadth .52 mm. (.024 inch). The 
nnae are more than half as long again as the body (1.8 mm.), 
I 6th joint being much the longest, equaling the 3d and 4th taken
