d.4. cornifolice Fitch: Cat. Horn. N. Y., 1851, p. 65; Oestlund, 

 Bull. Geol. and Nat. Hist. Surv., Minn., No. 4 (1887), p. 53. This 

 species has often been confused with the more common Aphis on 

 Cornus, A. helianthi. In his original description of cornifolice Fitch 

 says, "Apterous females black," and Oestlund describes the color 

 of the abdomen of the winged viviparous female as "dark brown." 

 I have received from Mr. Monell a note on this species, an abstract 

 of long color notes made by Mr. Th. Pergande. I copy in full as 

 received from Mr. Monell. 



"315^ On Cornus Ivs. Maryland, May 26-27, '85 (Abstract of long color notes). 

 Winged: — Hd. and thorax, nectaries and tail black. Abdomen dark brownish, almost 

 blk. Wings pale dusky. Apterous. Dull blk., the abdomen somewhat brownish. 

 Pupa. Hd. and thorax dark greenish covered with fine mealy grayish excretion. 

 Abdomen greenish brown with grayish excretion, often two pale distinct stripes of 

 excretion on dorsum. Wing pads dull yellowish. 



"This is all essentials of color notes verbatim — from Th. Pergande. J. T. 

 Monell."
