Aphis sp. ? A small j'ellowish-green aphid which infested the common 

 Euj)1iorhia of the Bessarabian Steppe. I was unable to procure 

 any winged representatives of this species, although I made several 

 expeditions for that purpose. The apterous specimens have very 

 distinctive abdominal protuberances or spines. 



Cryptosiphum artemisiae Buckton. Apterous examples were taken 

 under the leaves of Artemisia on the Steppes in July. 



Dryohius croaticus Koch. This fine aphid was found in July on the 

 shoots springing from the stump of an oak tree. According to 

 Buckton, this is its tj'^pical habitat. He remarks : " They are 

 usually stated to prefer the branches springing from oak stumps " 

 (vol. iii, p. 76). This species was almost spider-like in its activity, 

 and was numerously attended by ants. 



Schizoneura ulmi Linn. Common on elm trees at Odessa in June. 



Tetraneura ulmi De deer. The characteristic flask-shaped galls were 

 found on elms at Odessa in July, but were then all empty.

Both the original description and the figure of- the t3'-pe species are 

 wron^, for the clypeus is longer than the face, and the face is narrow and 

 formed by the two carinae in contact from base to near apex, and it is 

 not centrally carinate. It is synonymous with Faraproutista Muir.^
