SlPHOXOPHORA LIRIODEXDRI. Monell. 
“ Winged female: Head, thorax and two basal joints of the an¬ 
tenna red. Abdomen green, Honey-tubes, and apical portion of the 
antenna black. Antenna much longer than the body; the tubercle 
near the apex of the fifth joint very distinct. Honey-tubes usually 
slightly incrassated at the base, about four times as long as the tarsi. 
Style slender, when fully extended one-third as long as the honey-tubes, 
more or less greenish. Wings hyaline. Stigma long, much tapered at 
base and apex; apex acute, nearly opposite the middle of the stigmal 
vein. Distance between the apex of the stigmal vein and the apex 
of the upper forklet equal to half that between the forklets. Length 
2.54 mm, to tip of w r ings 4.57 mm. 
On Liriodendron tulipifera , June, July; St. Louis, Mo. 
The leaves on which this species lives do not curl up as in S. tilioz y 
but soon turn brown and drop off. 1 ’ 
SlPHOXOPHORA CRATiEGI. Monell. 
“Apterious individuals: General color pale yellowish-green, with a 
darker green mark on each side of the base of the abdomen and 
scarcely preceptible, darker green irregular marks near the base of the 
honey-tubes. Antenna? about three times as long as the body, black, 
with the basal third pale greenish; frontal tubercles fully as long as 
the second antennal joint; seventh joint tapering to an exceedingly 
slender point in the adult apeterious individuals, as long as the fourth, 
fifth and sixth joints taken together. Honey-tubes long and subcylindric, 
extending beyond the tip of the abdomen, pale, almost translucent. 
Style half as* long as the honey-tubes, pale yellowish. Legs entirely 
greenish. Length 2.28 mm. 
“On the under surface of leaves of Cratmgus coccinea. July, St. 
Louis, Mo.” 
I think it quite probable, that when the winged individuals of this 
species are procured, it will be found that it is not a Siphonophora.

Mr. Monell’s species is described as follows: 
“General color very dark, dull, greenish-brown. Head and thorax

black; tibiae dusky at base and apex; tarsi black. Tail yellowish-green,

“Dorsum smooth. Antennae much longer than the body, black; third 
joint very tubercular; fourth joint distinctly tubercular; remaining 
joints not so; third joint about as long as the fifth, sixth and seventh
