No. 34-] HEMIPTERA OF CONNECTICUT: CICADELLIDAE. 69 



A common species on poplar and previously reported from New 

 England. 



M. ferrugineoides (Van Duzee). Pediopsis ferrugineoides Van 

 Duzee. Pediopsis bifasciata Gillette and Baker. 



Ent. Amer., v, 171, 1889. 



Rusty brown, usually dark with a light band including the cross 

 nervures of the elytra. Vertex and pronotum yellowish brown, 

 scutellum darker. Length 5.5-6 mm. 



Feeds on narrow-leaved willows. Professor Osborn has 

 recorded it for Maine and it perhaps occurs in Connecticut. 

 M. trimaculata (Fitch). Pediopsis trimaculata Fitch. Pediopsis 

 insignis Van Duzee. 



Homop. N. Y. St. Cab., 60, 185 1. 



Dull brown, elytra with two or usually three white spots in a 

 row on apical half of costa, nervures paler. Vertex and pronotum 

 more yellowish brown, scutellum with darker basal angles. 

 Length 4-4.25 mm. 



This is reported from wild plum by Van Duzee. Three 

 records are at hand. 



Westville, 31 July, 1901 ; Hamden, 23 Aug., 1910 (W. E. B.) ; New 

 Haven, 18 June, 1921 (B. H. W.) ; Cromwell, 27 Aug., 1920 (B. H. W.) 

 on Prunus Pissardii. 



M. sordida (Van Duzee). Pediopsis sordida Van Duzee. 



Can. Ent, xxvi, 89, 1894. 



Rusty brown, often shading to yellow, elytra subhyaline in 

 female with brownish areas. Male elytra often darker, chestnut 

 brown. Vertex, pronotum and scutellum paler. Length 

 4.75-5 mm. 



Reported from Maine by Professor Osborn, and its distribution 

 should extend south and west of this locality. 



Cornwall, 5 June, 1921, New Haven, 16 June, 1921 (B. H. W.). Both on 

 willow. 



Oncopsis Burmeister. 



Bythoscopus Amyot and Serville. 



Vertex short and broad, almost parallel margined, produced but 

 obtusely angled. Pronotum produced anteriorly beyond the 

 anterior margin of the eyes, the surface covered with transverse 

 wrinkles or striations extending almost transversely across the 

 pronotum. In this respect it is easily distinguished from 

 Macropsis to which it is closely related. Elytra with a distinct 

 appendix. 



The members of this genus are arboreal and similar in that 

 respect to all the genera of the Bythoscopinae except Agallia. 

 Although one or two species are reported as collected from blue- 

 berry, feeding observations show them to be closely restricted to 

 trees and shrubs such as birch, walnut, alder, hazel, etc.
