 21 Oct., 1909; Bridgeport, 20 Sept., 1920; Norwalk, 8 Sept., 1920; Strat- 

 ford, I Sept., 1920 (B. H. W.) ; Hamden, 20 May, 1920 (M. P. Z.). 



I. snowi Gillette and Baker. 



Hemip. Col, 79, 1895. 



Another pale green species with two small spots on vertex and 

 elytral suture narrowly black or brown. Elytra greenish hyaline, 

 nervures margined with sparse pubescence. Length 5.5-7.5 mm. 



Reported from New York, and perhaps occurs in Connecticut 

 as an adult during July and August. 

 I. suturalis Fitch. 



Hom.op. N. Y. St. Cab., 59, 1851. 



Pale yellowish, characteristically marked by a broad dark stripe 

 along the elytral suture, tips smoky. Scutellum with basal angles 

 dark. Vertex and pronotum unmarked. Length 5-5.75 mm. 



Occurs on poplars and willows and perhaps occasionally is 

 found on birch, as it has been taken from that plant although not 

 definitely known to be feeding upon it. 



Hamden, 11 June, 1921 (B. H. W.). 

 I. suturalis var. lunaris Ball. 



Can. Ent., xxxiv, 311, 1902. 



Similar to preceding with sutural stripe interrupted by a lunate 

 mark on middle of clavus. Tips of elytra smoky, appendices over- 

 lapping and appearing as a third elongated dark spot on elytra. 



Often found in company with suturalis on willows and poplars. 

 A common variety in the eastern states. 



New Haven, 19 June, Cornwall, 18 July, 1921 (B. H. W.). 

 I. verticis (Say). Jassus verticis Say. 



Jour. Acad. Nat. Sci. Phila., vi, 308, 1831. 



Resembling alternatus, but smaller and lighter in color. Pale 

 brownish often faded, vertex with two black spots. Basal angles 

 of scutellum black. Elytra subhyaline, nervures alternately brown 

 and white. Length 4.25-4.5 mm. 



It is doubtful whether this species occurs in the state, but may 

 be found in small numbers during July, August and September. 



Macropsis Lewis. 



Pediopsis Burmeister. 



Vertex obtusely angularly produced, almost parallel margined, 

 very short and broad. Pronotum broad, produced anteriorly 

 beyond the anterior margin of the eyes (at least in American 

 species), dorsally roughened by oblique striations extending from 

 the median anterior margin to the humeral angles. 



The members of this group, as in the preceding, are tree and 

 shrub inhabiting and are apparently limited in their feeding habits
