204 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



The insects are active and are good fliers. Another of the 

 interesting records for the State is the capture of this species on 

 white pine at New Haven, June 9, 1913, by M. P. Zappe. It has 

 already been mentioned that there are very few instances known 

 of any membracid inhabiting an evergreen. 



Hosts: Black oak (Q. velutina), scarlet oak, white pine.

I have seen only one specimen of this species, a paratype, with 

 which Mr. Woodruff has very kindly presented me. 



It is an attractive little species with well-defined black and white 

 markings on a gray ground color. It is near O. salamandra but 

 is smaller and differently marked. 



The host and locality records here given are taken from the 

 above-mentioned specimen. 



Host: Quercus coccinea. 



Litchfield, 14 July, 1919 (L. B. W.). 



Vanduzea Coding. 



A genus close to Ophiderma but distinguished by the terminal 

 cell of the tegmen which in Vanduzea is transverse and truncate 

 at the base. 

 V. arquata (Say).

Should be the commonest membracid in the State but has only 

 occasionally been reported and curiously enough in one instance the 

 specimens were taken from giant ragweed where their appearance 

 must have been accidental. 



Extremely abundant throughout eastern United States on locust 

 on which host it often appears in such numbers that several 

 hundred individuals may be collected from one tree. 



The insect is small, light chocolate-brown with deep brown and 

 yellow-white markings in the female, and darker colors in the 

 male, the dorsum regularly rounded, pubescent and punctate, the 

 tegmina hyaline, clouded at base and near middle and extending 

 beyond the tip of the posterior process which is sharp. The 

 distinguishing character is the transverse terminal cell of the 

 tegmen.
