Publilia Stal. 



A genus near Enfylia but showing a much less elevated crest 

 and a much weaker median notch. Some of the forms are merely 

 depressed in the center and the prothorax is only slightly 

 compressed. 

 P. concava (Say).

Extremely abundant. A grass and shrub inhabiting species 

 usually taken in sweeping. According to Mr. Woodruff, the 

 common host about Litchfield is alder. In New York it seems to 

 be most abundant on goldenrod. 



The species may be distinguished from Entylia bactrimia, the 

 only other species in the State with which it is likely to be con- 

 fused, by the slight dorsal depression and the general rounded 

 shape of the pronotum. The color varies from gray to black and 

 the pronotum is irregularly ridged and deeply punctate. The 

 tegmina are largely covered by the pronotum. 



Hosts: Goldenrod, skunk-cabbage, New England aster, worm- 

 wood, alder.

Family CERCOPIDAE.* 



By Louis Agassiz Stearns, M.Sc. 



The insects known under variously applied descriptive names as 

 cuckoo-spit, spittle insects, frog-hoppers and leaf-hoppers, together 

 with the Cicadellidae (Jassoidea) and Fulgoridae, and belonging 

 to the family Cercopidae, are of world-wide distribution. 

 Although members are recorded for every Zoological Subregion, 

 except the Hawaiian, the "headquarters" of this family is in 

 Central and South America and in the Oriental Region and the 

 Malayan portion of the Australian. Comparatively few repre- 

 sentatives are known to occur in the Nearctic Region. This paper 

 recognizes six genera {Monecphora, Aphrophora, Lepyroniu, 

 Philaenus, P hilar onia and Clastoptera), comprising twenty-two 

 species, as included within the Nearctic fauna. Two varieties 

 (infiiscatus and pallidtts) of one species (Philaronia bilineata 

 Say) are described herein as new.
