298 (483). Cymus luridus Stal, 1874, 126. 



Elongate-oval. Pale straw-yellow, often slightly tinged with reddish- 

 brown; pronotum with front margin and a stripe each side, often fus- 

 cous; elytra sometimes marked with vague fuscous blotches; tips of 

 corium and clavus, apical half of fourth antennal, meso- and meta- 

 sterna and tips of tarsi, often tinged with fuscous. Basal joint of an- 

 tennas scarcely reaching apex of head. Pronotum subtrapezoidal, not 

 strongly convex behind, disk with an obvious pale obtuse carina in front 

 of middle. Scutellum with a similar median carina. Length, 4.8 — 5 mm. 



White Plains and Cascade Lake, Adirondack Mountains, N. 

 Y., Sept. 29 (Barber). Not as yet taken but should occur in 

 northern Indiana. The general range of luridus is northern, 

 ranging from Ontario and Maine to Colorado, Vancouver and 

 California. Stal's types were from New Jersey, and it has not 

 been recorded south of that State. 



299 ( — ). Cymus robustus Barber, 1924, 87. 



Elongate-oval, more robust than luridus. Pale reddish-brown, or 

 brownish-yellow; head beneath and sternum often tinged with fuscous; 

 tip of fourth antennal and apex of corium fuscous; membrane hyaline, 

 often faintly mottled with fuscous. Head relatively broader and more 

 declivent than in luridus, antennae shorter than there, the basal joint 

 reaching or slightly surpassing apex of head. Pronotum as in key, the 

 median carina less evident than in luridus. Clavus and corium more 

 strongly punctate. Length, 4.5 — 4.7 mm. 



Lake Co., Ind., May 30 (W.S.B.). Lake and Porter coun- 

 ties, Ind., May 31 — July 9 (Gerhard) . Occurs on marsh grasses

 the State. Described from New York and Michigan. Recorded 

 by Barber (loc. cit.) as "feeding on flower and seed heads of a 

 tall species of bulrush (Juncus) ."

 sinuate near middle, hind portion of disk strongly convex; front portion 

 and scutellum each with a distinct median carina. Length, 3.2 — 3.5 mm.
