marked by dark cross bands. Head and thorax shining black; neck 
dull yellowish; abdomen yellowish, with some irregular dusky patches 
toward the tip. Antennae, which reach about the middle of the abdo¬ 
men, dusky, the basal half paler; legs dark, the bases of the femora 
pale; beak short, reaching only to the middle coxae. 
Apterous female. Reddish-brown, or tortoise-shell color; a lar^e, 
yellowish, triangular or Y-shaped spot, (the forks pointing backward) 
on the middle part of the abdomen; honey-tubes reduced to simple 
tubercles, yellow. There is often a palish stripe along the middle of 
the head and thorax. Antennae pale yellowish at the base. Length 
about .05 of an inch. 
Body more or less hairy; and although my notes, made at the time, 
fail to mention the fact, I think that some, at least, of the apterous 
specimens were covered with tubercles. 
Found in July, at Carbondale, Illinois, and the first part of Sep¬ 
tember, at Dubuque, Iowa, on the under sides of the leaves of young 
sprouts of Populus angulata (cottonwood). 
Chaitophortjs lonicera. Monell (Mss.) 
\ 
This and the two following species were discovered and named by 
Mr. J. Monell, of St. Louis,* to whom I am indebted for a specimen 
of this species and the brief characters given of the other two. He 
also included another species which I have referred to Callipterus as 
I am satisfied it belongs there. 
The characters given in Mr. Monell’s brief notes are as follows: 
“Wings hyaline; honey-tubes almost on a level with the abdomen, de¬ 
tected with difficulty; abdomen pulverulent with short tubercles on 
the edge.” 
From the dried specimen with which he favored me, I make out the 
following characters: 
Winged female. Wings as usual in this genus; third vein obsolete 
at the immediate base; second fork rather nearer to the apex than to 
the third vein; fourth or stigmatic vein curved at the base but the 
apical half is nearly straight; veins very delicate; wings also very 
delicate, but slightly smoky. Antennae longer than the body; third 
joint long and pustulated; seventh nearly or quite as long as the 
third. Honey-tubes reduced to mere tubercles. Beak reaching to the 
third pair of legs. Body greenish. 
This is certainly different from Phopalosiphum lonicera , Siebold— 
which has the honey-tubes distinctly enlarged in the middle, and 
reaching nearly to the tip of the abdomen. 
On the honey-suckle (Lonicera.) 
*Note.—T his and other species named bv Mr. Monell are noticed in the appendix.
