No. 34-] HEMIPTERA OF CONNECTICUT: FULGORIDAE. 27 



Subfamily Dictyophorinae. 



Key to Genera. 



1. Vertex produced and angulate before, frequently forming a long 



cephalic process 2 



Vertex short, transverse ; elytra in the short-winged form scarcely 

 exceeding the abdomen, convex ; anterior femora f oliaceous . . . 



Phylloscelis, p. 28 



2. Head moderately produced, depressed and carinate above ; 



cephalic process when present not exceeding the base of the 



frontal compartments Dictyophora, p. 27 



Head greatly produced in a cephalic process which is extended 

 much beyond the base of the frontal compartments, its superior 

 surface sulcate but not carinate Scolops, p. 27 



Dictyophora Germar. 



These are elongated, frail looking insects with nearly hyaline 

 elytra and more or less produced head. They are found in damp 

 situations in the warmer parts of the country. 



Key to Species. 



Vertex fully twice as Long as its basal width ; median carina extending 

 a little more than half way to the apex, the three frontal carinae 

 almost parallel throughout their length microrhina 



Vertex scarcely longer than its width at base, its median carina almost 

 attaining the apex; frontal carinae diverging basally (toward 

 the apex of the head), forming a spatulate compartment, con- 

 colorous at their extreme base where they meet in an acute 

 angle lingula 



D. microrhina Walker. 



List. Homop. ii, 315, 1851. 



A southern form which has been taken as far north as the 

 vicinity of New York City and may be taken in southern 

 Connecticut. 

 D. lingula Van Duzee. 



Proc. Acad. Nat. Sci. Phila., lix, 470, 1908. 



This species has about the same distribution as the preceding and 

 should be taken in Connecticut. The closely allied florens Stal 

 has black carinae at the apex of the head. It has not been 

 reported from north of Georgia. 



Scolops Schaum. 



A genus of rather small brown or gray leaping insects inhabiting 

 meadows and weedy spots. Their long cephalic process and habit 

 of standing well up on their hind legs gives them somewhat a bird- 

 like aspect. 



Key to Species. 



1. Elytra with supernumerary cross-veins forming many small 



areoles beyond the middle ; nervures slender sulcipes 



Elytra without supernumerary cross-veins toward their apex ; 

 nervures strong 2
