Sept,i9io.] Matausch : Observations on Memrracid/E. 169 



some nymphs which were perhaps of the same species. Nevertheless, 

 I could not be sure, for in spite of all my care I could not raise any 

 to maturity, as they required food for a longer time than it could be , 

 obtained in abundance. 



15. Telamona ampelopsidis Harris. 



Altogether I found five specimens of this species on Ampelopsis, 

 July 3 to 15. Of these one was male, two were females, one had 

 imperfecdy developed genitalia, while the other seemed to be in the 

 same condition but was damaged and I could not make sure. 



16. Telamona species? (labeled " near rccUvatci " by Mr. Van Duzee). 



I found one female, September 6 on Qucrciis, and another Septem- 

 ber 19. Both were darker in color, but otherwise corresponded with 

 this species. 



17. Cyrtolobus species? 



July 3 to 5 I found eight females on Qucrcus alba. I examined 

 one for eggs, and found eight. Because of this small number, and 

 because I found no males, I concluded that it was rather late in the 

 season for this insect. 



18. Ophiderma flavocephala Gody. 



August I Mr. Bischoft collected one specimen at Rahway, N. J., 

 and also one identified as O. obscura by V'an Duzee. The latter spe- 

 cies is not mentioned in his " Studies on North American Membra- 

 cid?e,'' but was probably described later. 



19. Vanduzia arcuata Say. 



]Mr. Bischoff collected one male and two females at Rahway, N. J., 

 and September 8 I found a number of them at Cold Spring Harbor, 

 L. I., with ThcUa bimaciilata. They were on Robinia but escaped. 

 At Elizabeth and Neward I found none. 



20. Publilia concava Say. 



This insect was not found here, in spite of the variety of species 

 of Salidago which occur. Mr. W. Reiff, however, on September 27 

 collected a great number of adults of both sexes and some nymphs 

 at Forest Hills, Boston, Mass., and was kind enough to send them 

 to me.
