No. 34-] HEMIPTERA OF CONNECTICUT: CICADELLIDAE. 1 57 



as broad as the segment and equaling in length the lateral angles. 

 Male valve more than twice as long as last ventral segment, pos- 

 terior margin with broad V-shaped notch extending from the 

 lateral angles one-third the distance to the base. Plates narrower 

 than valve and twice longer, margins almost parallel, tips broadly 

 rounded. 



This species was recently described from material collected in 

 New Haven and also material collected in Kew Gardens, London, 

 England, by Prof. J. G. Sanders. 



New Haven, on pear; July 6, 1920 (B. H. W.), type material; 4 Aug.,

Empoa Fitch. 



Anomia Fieber. 



Typhlocyba Sahlberg. 



Vertex very blunt in front, produced but scarcely angled. Ely- 

 tral venation distinct as given in key with apical cell formed 

 between outer and middle sectors, triangular. As a rule the 

 species are rather pale in color with few dull markings.

 are pests of shrubbery and fruit trees. All have two or more 

 broods a season.
