378 FAMILY XL — LYG^EID^. 



most of its range. The young, probably of a second and hiber- 

 nating brood, appear to be most common in September, all 

 stages being then found beneath leaves and other cover along 

 sandy banks of streams. 



317c (502d). Geocoris uliginosus limbatus Stal, 1874, 136. 



Easily distinguished by its reddish-brown or paler head and pale 

 side margins of pronotum. Structural characters the same as in the 

 typical form, but brachypterous individuals more frequent. In these 

 the membrane is very short, reaching base of fifth dorsal. 



Marion and Putnam counties, Ind., July 14 — Oct. 23. Occurs 

 with the typical form and in the northern states often more 

 common. At Buffalo, N. Y., Van Duzee found it "moderately 

 abundant on damp spots in meadows and grain fields." The 

 best marked variety of the species. 



318 ( — ). Geocoris frisoni Barber, 1926, 38. 



Oblong-oval, brachypterous. Head dull yellow to reddish-yellow, the 

 ridges of tylus and a curved line about each ocellus paler; pronotum, 

 scutellum and elytra pale grayish-yellow, calli and median carina of 

 scutellum dull yellow; dorsum of abdomen fuscous, connexivals pale 

 yellow; legs and under surface dull yellow, sides of ventrals fuscous- 

 brown; beak piceous, basal joint paler; joint 1 of antenna? yellow, 2 and 

 3 dusky, 4 fuscous. Pronotum depressed, twice as wide as long, side 

 margins parallel ; calli and extreme base smooth, remainder punctate as 

 in key. Scutellum as broad at base as long, closely and evenly punctate, 

 the low median carina smooth. Elytra obovate, reaching middle of fifth 

 dorsal, punctate as in key; membrane hyaline, very short, scarcely over- 

 lapping. Length, 3.1 — 3.3 mm. 



Vigo Co., Ind., Jan. 5— April 4 (W.S.B.). Arenzville, 111., 

 Aug. 14 {Barber). Occurs only in sandy localities, hibernating 

 beneath mullein leaves and other cover. Varies somewhat in 

 color, the head, scutellum, under surface and legs sometimes 

 in great part fuscous. Known only from Indiana and Illinois. 



II. Hypogeocoris Montandon, 1913, 55. 



Short oval species differing from Geocoris mainly by the char- 

 acters given in generic key. Upper surface, except head and 

 membrane, coarsely, rather sparsely irregularly punctate ; 

 ocelli placed midway between inner margin of eye and middle 

 of vertex; beak reaching hind coxae; clavus very narrow but 

 slightly more elevated than corium. The Isthmocoris of McAfee 

 (1914, 127) is a synonym. Two species are known, both oc- 

 curring in our territory.
