THE APHID GENUS AMPHOROPHORA MASON 



29 



Cotypes. — Alate viviparous female deposited in the U. S. National 

 Museum, Cat. No. 26375, in the Maine Agricultural Experiment 

 Station and in the collection of Harold Morrison. Paracotype slides 

 of the male and oviparous female, which are a part of the Swain collec- 

 tion, are returned to Stanford University. 



AMPHOROPHORA ESSIGWANAI, new name

Rhopalosiphum indicum v. d. Goot of Essig and Kuwana, Proc. Cal. Acad. 

 Sci., vol. 8, no. 3, 1918, p. 55. 



In 1916 Van der Goot described and figured his Rhopalosiphum 

 indicum from the apterous form only, taken on an unknown host 

 plant. In 1917 he described the alate form of what he considered to 

 be the same species, taken apparently on the wing. Both of these 

 collections were made in India. In 1918 Essig and Kuwana, not 

 having received the above description of the alate, described the 

 alate form of what they considered to be this species, taken on Eus 

 caphis japonica and Staphylea humalda in Japan. The two descrip- 

 tions apparently do not refer to the same species. Essig kindly 

 loaned me some of his specimens. I also have specimens sent by 

 Takahashi taken in Formosa on an unknown host and determined 

 by him as indicum v. d. Goot. They are most certainly different from 

 Essig and Kuwana's specimens, and they agree very well with Van 

 der Goot's description. Van der Goot's description of the alate 

 must be accepted as indicum until proven otherwise, and I am 

 referring Takahashi's specimens to this species. A new name must 

 therefore be given to Essig and Kuwana's species and I here propose 

 essigwanai. 1 am removing indicum v. d. Goot from the genus 

 Amphorophora, where it was placed by Takahashi, as it is not 

 typical. 



In 1918 Matsumura described his Rhopalosiphum miniatum, which 

 Takahashi says is synonymous with indicum v. d. Goot. I have not 

 seen it, but I am accepting Takahashi and am not considering it in 

 connection with the Amphorophora. 



The following descriptions and the drawings are made from the 

 specimens furnished by Essig.
