Wingless individuals .—(The only ones seen).—Antennae on distinct 
tuoercles, seven-jointed, as long or longer than the body; third joint 
long, but not so long as the fourth and fifth united; the inner mar¬ 
gin of the tubercle and first joint, each very distinctly extended and 
enlarged into a prominent rounded and blunt process, more distinctly 
so than any other American species with which I am acquainted. 
Honey-tubes extending beyond the abdomen and distinctly enlarged 
in the middle. Tail short and conical. 
The very young are green or pale pink. Eyes dark brown or black. 
Those that appear to be full grown vary in color from a reddish-brown 
to a brownish black on the upper side, paler beneath. Legs pale through¬ 
out. Of medium size. In some individuals the honey-tubes do not 
appear distinctly enlarged in the middle. 
I have considerable doubt as to the proper generic position of this 
species, as the inner margin of the tubercle and first joint are not 
toothed but tuberculiform. The form of the honey-tubes would place 
it in Drepanosiphum. 
Note .—The plant on which this species was found was immature, 
it was supposed to be S. nodosa , but there is reason to doubt this, 
and the matter cannot be decided until next season.

Genus MEGOURA. Buckton. 
i • 
“Head broad; front flat; rostrum rather short. Antenna much long¬ 
er than the body; frontal tubercles large; remote at their bases; third 
joint longest; second joint twice the size (length) of the first; fourth 
joint longer than the fifth; seventh joint setaceous. Abdomen globose, 
convex; cornicles (honey-tubes) long, dilated in the middle, expanded 
at the ends, or trumpet-mouthed. Cauda (tail) markedly long and 
thick. Wings and legs as in Siphonophora.' 1 '’ Buckton. 
Although some of the characters of the following species may vary 
slightly from Buckton’s generic description, yet i am fully satisfied 
that it belongs to this genus, and that Buckton was clearly justified 
in forming the genus.

Megoura solani. n. sp. 
A very singular species of plant-louse found on the tomato. 
Winged female.— Antenna? seven-jointed, a little longer than the 
body; first and second joints short; third and seventh longest, nearly 
equal; fourth a little shorter than the third; the fifth not quite as long 
s the fourth; sixth about half or less than half the length of the
