A SYNOPSIS OF THE APH1DIDAE 73 



85. Myzus aquilegiae Essig 



Shinji, Can. Ent., vol. 40, p. 49, 1917. Myzus sp. (list). 



Essig, Univ. Calif. Publ Entom., vol. 1, p. 314, 1917 (orig. desc.). 



Eecords. Aquilegia truncata; Berkeley, 1916 (Essig) : A. vulgare, Inverness, 

 Marin County (Shinji). 



This species was recently described by Essig from specimens found 

 on columbine on the campus of the University of California, Berkeley. 

 The author has had access to cotype specimens, although he has never 

 collected it himself. 



86. Myzus braggii Gillette

Gillette, Can. Ent., vol. 11, p. 17, 1908 (orig. desc.). 



Davidson, Jour. Econ. Ent., vol. 5, p. 409, 1912. Phorodon carduinum 

 (Walker) (list). 



Eecords. Cynara scolymus; Courtland, Oakland, and San Jose (Davidson) ; 

 Riverside, January and February, 1917. 



The author found this species during the early spring of 1917 

 infesting the leaves of artichoke in Riverside. The determination of 

 specimens was verified by C. P. Gillette. Davidson reported Phorodon 

 carduinum (Walker) from artichoke in the San Francisco Bay region. 

 His specimens were determined by J. Monell, but P. Van der Goot 

 was doubtful as to its identity. Davidson himself has decided that 

 the species is Myzus braggii Gillette. There is no doubt but that the 

 species on artichoke in California is M. braggii Gillette, but whether 

 or not this is the same as P. carduinum (Walker) is uncertain.
