the specimens cannot possibly be placed in Aphis while others on 
further examination appear to belong to that genus as suggested by 
Mr. Monell. Until more specimens are obtained and this matter cor¬ 
rectly determined, the name I originally gave had better stand. 
Aphis cornifolee. Fitch. 
Mr Monell gives the following description of the winged individual 
of this species: * 
“Head and thorax dusky; abdomen dark fuscous. Fore femora entirely 
yellow; hind femora yellow only at base; base of tibiae yellow in all 
the legs; tarsi more or less dusky. Antennae more or less dusky, as 
long as or a little longer than the body. Nectaries dusky, cylindric 
scarcely longer than the tarsi. Abdomen truncate. Style dusKy, short 
but distinct. Wings hyaline. The stigma projecting somewhat above 
the margin, much as in A. coreopsidis , tapered abruptly at apex. Costa 
and stigma pale yellow; oblique veins dusky. Length 1.27 mm; to 
tip of wings 2.28 mm. 
On the under side of leaves of Cornus florida , and C. paniculata , 
June—July; St. Louis Mo.” 
Aphis atriplicis. Linn. 
Found on Chenopodiaceae by Mr. Monell and Miss. Middleton. 
Walker decides that this species is but a variety of A. rumicis Linn. 
Hr. Fitch appears to coincide with him in this opinion. Passerini 
considers them as distinct. 
Aphis hyperici. Monell. 
“Winged individuals: General color light reddish, covered with pul¬ 
verulent matter; antennie on short tubercles, a little longer than the 
body; third joint as long as the fourth, fifth and sixth taken together; 
apical joint about twice as long as the preceding. Wings hyaline; 
stigmal vein much curved;, distance between the base of the cubitus 
and that of the stigmal vein equal to the distance between the apices 
of the lower forkiet and the lower branch of the cubitus. Nectaries 
very short, only detected with difficulty. Tail reddish, little over 
half as long as the tarsi, slender and terete. 
Length 1.06-1.27 mm; to tip of wings 1.77-2.28 mm. Living in col¬ 
onies on the young twigs and under side of leaves of Hypericum Jcal- 
mianum, to which species it seems to be confined. July, St. Louis 
Mo.” J 5
