FURTHER NOTES ON THE MEMBRACID GENUS 

 OPHIDERMA FAIRM. (HEMIP.-HOMOP.). 



By Lewis B. Woodruff, 

 New York, N. Y. 



Ill the December, 1919, number of this Journal the writer set 

 forth the results of his study of the Membracid genus Ophidcrma, 

 but certain of his conclusions were perforce stated tentatively, owing 

 to lack of positive evidence to substantiate them. That lack in some 

 important instances has been supplied during the past season's col- 

 lecting, and by the proof thus furnished it is found that the deduc- 

 tions therein arrived at chiefly by logical processes are correct. 



One of them had to do with Gibson and Wells' O. fraterna and its 

 probable status as the male of Coding's O. flava. That supposition 

 is now established as a fact. During the month of June, at Litch- 

 field, Conn., males of fraterna were frequently taken in association 

 with females of flava, and in at least three instances they were taken 

 in copulation; thus removing any possible doubt as to the identity of 

 the former species. As suggested in the paper above referred to, the 

 specific name fraterna Cib. & Wells must sink as a synonym of flava 

 Codg., and these two very differently colored insects be brought 

 together in our cabinets as the two sexes of the latter species. 



My series of males of flava taken this past summer consists of 

 fifteen specimens, ranging in date from June 22 to July i, to wit: the 

 three paired and in copula take on Quercus rubra (June 29 and 30), 

 three others also on Q. rubra, seven on Q. coccinea and two on Q. 

 alba. The females of this species taken this season were found on 

 the three foregoing 'species of oak in about the same proportions 

 respectively, but specimens of this sex continued to be taken for more 

 than a month after the males had disappeared, a phenomenon which 

 seems to be usual in the fainily. In this connection it is significant 

 that the last male taken, on July i, was dead when beaten from 

 the tree.
