SUBFAMILY I. — PENTATOMIN^E. 167 



Rhaphigaster catinus Dallas, a synonym, were from "Canada." 

 Van Duzee (1904, 59) states that about Buffalo, N. Y., it is 

 "tolerably abundant on various deciduous. trees from August to 

 October." The notes on its distribution show that it is much 

 less common than dimidiata. 



114 (186). Banasa sordida (Uhler), 1871, 98. 



Oval, subconvex. Above dull yellow, so tbickly and evenly marked 

 with dark punctures as to appear almost fuscous; antennae greenish- 

 yellow, the outer two joints darker; narrow edges of side margins of 

 pronotum, connexivum, basal third of elytra and tip of scutellum, pale 

 yellow; membrane fuscous at base, paler toward apex; connexivum pale 

 brown, its incisures blackish; under surface dull yellow sprinkled with 

 reddish punctures and dots ; abdomen with four rows of large vague ill 

 defined blotches, and a dot on the end of each ventral incisure, fuscous; 

 legs dull yellow to greenish-fuscous. Head as wide across the eyes as 

 long, thickly and rather finely punctate, its front gradually feebly nar- 

 rowed ; cheeks equalling tylus ; beak reaching middle of third ventral. 

 Pronotum with front half moderately declivent, humeri obtusely rounded ; 

 disk with numerous smooth, irregular transverse yellowish lines between 

 the wavy lines of punctures. Scutellum with similar lines between the 

 rows of punctures, a small spot on each basal angle and the tip smooth. 

 Elytra evenly and rather coarsely punctate. Abdomen very finely, 

 sparsely punctate; thoracic pleura more coarsely and closely so. Genital 

 plate of male with hind margin broadly and rather deeply concave. 

 Length, 10- — 11.5 mm.; width, 6 — 7.5 mm. 



Grand Tower, 111., June 30 — July 10 (Urbana collection) ; Wash- 

 ington, D. C, Oct. 20 (Osboru). Not as yet known from, though 

 probably occurs in, Indiana. Ranges from New England to 

 Vancouver's Island and California, south to Maryland and 

 Virginia. Nothing regarding its habits has been recorded. 17 



115 (187). Banasa packardi Stal, 1872, 43. 



Elongate-oval, subdepressed. Above dull greenish-yellow or pale 

 reddish-brown, very sparsely and irregularly marked with large blackish 

 punctures; antennae greenish at base, the outer joints reddish; basal 

 third of pronotum sometimes dark green ; tip of scutellum green or yel- 

 low; elytra often tinged with reddish; membrane dusky brown, its basal 

 angles fuscous ; abdomen greenish-yellow, reddish or fuscous with three 

 rows of large paler yellow spots; legs greenish-yellow; claws and tip of 

 beak black. Head slightly longer than wide, feebly tapering, its apex 

 rounded ; cheeks rather coarsely and very sparsely punctate ; second 

 joint of antenna? scarcely half the length of third; beak reaching base of 



37 Parshley. in his keys (1915. 176, and 1923. 768). states that the nosterior 

 lateral angles of abdominal segments of sordida are acuminate and those of dimidiata 

 and cairn obtuse, whereas the reverse is the case. He also erroneously states that in 

 dimidiata the margins of the ventral segments have conspicuous black dots.
