APHIDID.E. 



BY T. D. A. COCKERELL. 

 Siphocoryne pastiiincse (Linne). 



Beulah, N. M., July 26, and in vast numbers August 2, on fruit- 

 ing unibles of Heracleum lanatum. 



Winged £: pale dull green; dorsum of head, ruesothorax and scutellum, 

 shining black; a large square black patch on middle of abdomen, followed by 

 three, transverse black bars. Legs pale greenish, ends of tarsi black. Stigma dark 

 brown. Anteunse, nectaries and cauda short. Mesosternum black; a black patch 

 on under side of abdomen near tip. Young, apple green with black eyes; some 

 specimens are pink. 



The species has not been recorded from America under the above 

 name, but I believe S. archangelicce Oestlund is a synonym. I 

 wanted to believe that the celery aphid figured in Bull. 102, Michigan 

 Agr. Exp. Sta., p. 20, was also Siphocoryne, but while the venation 

 agrees, the antennae are much too long. 



Aphis epilobii, Kalt. 



Beulah, N. M., on a flowering head of Epilobium angustifolium ; 

 extremely abundant, covering the whole surface. Attended by 

 Fur mica sanguinea. 



Winged 9: entirely black, the abdomen shining; anterior legs more or less 

 pallid ; beak scarcely reaching middle coxae ; antennae shorter than body ; ventral 

 surface of thorax olive brown to black, of abdomen usually dull dark sage green ; 

 wings hyaline, stigma blackish or pale. Pupa with wing-pads has a pale brown 

 bead and thorx, and dark slate abdomen. Apterous form dark slate-color, white- 

 pruinose; basal two-thirds of antennae, nectaries and legs (except tarsi) whitish 

 or yellowish-white. Very young vary from slate gray to pale orange, and occa- 

 sional half-grown examples are brownish orange. 



The species is new to America. 



Aphis clienopodii Cowen. 



Beulah, N. M., August 5, on Chenopodium album, curling the 

 leaves. 



Winged 9 : head and thorax black, abdomen green without spots. Opterous 

 form light green, pulverulent; eyes black (reddish in younger ones) ; cauda quite 

 long; nectaries short, slender; legs pale yellowish, tarsi blackish. The antenna] 

 joints of the winged form measure in (i. (3.) 320, (4.) 160, (5.) 160, (6a.) 120, (6b.) 



215. 



Aphis veralri Cowen. 



Beula, N. M., July 27, etc., abundant on leaves of Veratrvm. 



Apterous form black ; basal half of antenna? (except extreme base) ; anterior 

 femora and all the tibise dull white.
