all other species of Membracidae by the uncovered scutelhim. In general 

 appearance this insect suggests a large cercopid. 



The life history of this species has not been completely worked out owing 

 to the fact that no way has been found of rearing the nymphs in the 

 laboratory. The first nymphs have been observed on August 13. The 

 eggs are laid in young stems, and there is reason to believe that they may 

 also be laid in the buds altho such oviposition has not actually been 

 observed. The eggs winter over and are slow to hatch, making the species 

 rather late in appearing. There is apparently but one brood a year. 

 It is most numerous in Stations J, K, and N. 



Technical description. — Gray -brown mottled with black; entire body broad and flat; 

 pronotum roundly swollen above line of abdomen and wings; wings broadly tectiform. 



Head perpendicular, twice as broad as long, roughly sculptured, closely punctate, densely 

 pubescent, deep bro\\Ti at base; eyes prominent, extending beyond lateral margins of 

 pronotum, dark brown margined with lighter; ocelli small, pearly, farther from the eyes 

 than from each other, with deep depression between them; elypeus prominent, broad, lighter 

 in color than vertex above, extending far below lateral margin of head. 



Prothorax subspherical with high median carina, coarsely punctate, pubescent; light 

 brown marked with black on median ridge and above head; posterior margin truncate 

 except for narrow process which projects to angles of tegmina and short sharp tooth on each 

 latero-posterior angle. Scutellum broadly exposed, wide at base, truncate at tip, which 

 does not reach apex of posterior process. 



Tegmina translucent, pubescent, inner margins straight and meeting at median dorsal 

 line; veins prominent and nodulate; apices of tegmina extending beyond tip of abdomen. 

 Legs and undersurface of body light brown mottled with white. Undersurface of abdomen 

 often tomentose. 



Length 9-10 mm.; width 3 mm. 



SUBFAMILY MEMBRA CINAE 



The basin yields two species of the subfamily Membracinae, belonging 

 to two different genera — Campylenchia and Enchenopa. These genera 

 may be distinguished from each other by the characters of the pronotal 

 horn. In Campylenchia the lateral ridges of the anterior horn are located 

 close to the superior margin, and the inferior carina is not foliaceous; 

 in Enchenopa the lateral ridges are located about equally distant from the 

 superior and inferior margins, and both the superior and the inferior 

 carina are foliaceous.
