Winged individuals. —Wings pellucid, veins slender and pale brown; 
third vein obsolete at the base; second fork nearer to the apex of the 
wing than to the third vein; fourth vein curves somewhat rapidly 
near the base and then is nearly straight; stigma not very distinct, 
posterior angle distinct but very obtuse. Antennae not quite as long 
as the body; third joint longer than the seventh which is about the 
same length as the fourth; fourth and fifth about equal, each nearly as 
long as the third; sixth about half the length of the seventh. Similar 
in color to the wingless but rather darker. Anterior femora and the 
tibiae of all the legs pale; eyes black. No honey-tubes visible; beak 
reaching nearly to the base of the third pair of legs. 
Wingless individuals. —Purplish, pruinrose or covered with a powdery 
substance, margin of the abdomen expanded, with a row of black dots 
along the sides. Indications of very minute, black honey-tubes, but 
these are more apparent than in any other specimens. Tarsi, knees 
and tips of the antennae dark. Antennae a little longer than the 
thorax. 
Found on Hypericum prolificum , on the leaves and their petioles. 
Size small. 
In some of the specimens the second fork presents a very distinct 
fork. The seventh joint in this species is really but a long spur to 
the sixth, a strong power showing that there is no articulation between 
the two in specimens rendered translucent by long immersion in Can¬ 
ada balsam. But after all is this not true in reference to the Aphidini?

Genus OALLIPTERUS. Koch. 
Passerini and Buckton place this genus in Lachnini which group 
they characterize as containing species with six-jointed antennae. Koch 
also gives it the same position in his tabular arrangement, but in the 
body of his work this arrangement appears to have been abandoned in 
some respects, and there the genus is placed in advance of Lachnus. 
The antennae are in fact seven-jointed counting the portion beyond the 
offset at the end of the sixth as a joint, as is done in the other 
Apliidini. 
Characters.— Front wings with the third discoidal vein twice forked; 
posterior wings with two discoidal veins. Antennae seven-jointed, not 
on tubercles, third joint longest; seventh joint shorter or not longer 
than the sixth, sometimes appearing as but a spur to the sixth. 
Honey-tubes short, sometimes sub-obsolete. The beak short or of but
