SlPHONOPHORA (?) CALENDULELLA. Monell. 
I have some doubt as to the generic position assigned this species, 
but it is impossible from Mr. Monell’s short and imperfect description 
to form a decided opinion on this point. 
“Viviparous apterous females: General color very pale whitish-green, 
varying to yellowish. Antennae whitish, as long as the body, mounted 
on porrect tubercles. Legs yellowish, except the tarsi. The honey- 
tubes and short style concolorous. Length 1.27-1.77 mm. 
On the under side of leaves of Calendula micrantha. July, St. Louis, 
Mo.” 
Stphonophora tulip^e. Monell. 
This appears to be a different species from that I have described 
under the name Rhopalosiphum tulipce. One or the other of these 
species is probably identical with Aphis tulipce Fonscol, which Mr. 
Monell appears to have overlooked. 
“Apterous females : Pale green, with a dusky green stripe down the 
middle and darker green on the margin of the abdomen. Winged 
individuals with the antenme as long as, or a very little longer than 
the body, mounted on conspicuous tubercles which are not porrect; 
apical joint long and threadlike, longer than the fifth, and about five 
times as long as the sixth. Honey-tubes very long, dusky at apex. 
Tail when extended, about twice the length of the tarsi, pale green 
Length 3.04 mm; to tip of wings 4.82 mm. 
On petals and stigma of Tulips, April; St. Louis, Mo.” 
Drepanosiphum tiliae? Koch. 
Siphonophora tiliae, Monell. 
Mr. Monell describes his species as follows: 
“Apterous individuals : Head and thorax yellowish or yellowish-green; 
abdomen green, honey tubes with the basal one third green, apical por¬ 
tion black. 
Winged individuals: Head and thorax reddish-yellow; abdomen 
and style green antennae about twice as long as the body, mounted 
on conspicuous tubercles. Wings hyaline. Stigma yellowish. IIone} r - 
tubes sub-cylindric, four or live times as long as the tarsi. Length 
2.54—3.04 mm; to tip of wings 5.08 mm. 
On the under side of linden leaves causing them to curl.” 
I think it quite certain that this is indentical with or but a variety 
of Koch’s species. The number of the figure as given by Koch in 
his text is wrong, it should be 277 instead of 276.
