SUBFAMILY IV. — GEOCORIN^E. 377 



beetle, Megilla maculata (DeG.) ; all three within a space of a 

 few square inches. In summer and autumn it occurs on flowers 

 of Eupatorium and other Compositse along streams and marshes. 

 About Dunedin it is much more frequent than in Indiana, and 

 I have on several occasions taken it in company with G. punctipes 

 and G. bullatus beneath boards in a country barnyard. It is also 

 frequently found beneath cover along the bay beach and has 

 been taken at porch light. 



The known range of typical uliginosus covers practically the 

 entire United States and southern Canada, though many of 

 the records probably refer to its color varieties. Uhler (1877, 

 410) says: This is the most common species found in the At- 

 lantic region. It occurs on the ground in dark loamy spots, in 

 woods and near streams, often in places exposed to the sun and 

 around the roots of the horse-nettle, Solatium carolinense L." 



In addition to typical uliginosus, as treated above, there are, in 

 the eastern states, three forms or varieties recognized by 

 McAtee and Van Duzee which differ only in color from Say's 

 species. These are separated as follows : 



KEY TO COLOR VARIETIES OF GEOCORIS ULIGINOSUS. 



a. Head, except at apex, piceous. 

 b. Both pronotum and elytra more or less broadly pale margined, the 

 latter sometimes entirely pale. 317a. var. speculator. 



bb. Pronotum entirely piceous or with traces of pale along the sides. 

 c. Costal margins of elytra entirely piceous or narrowly pale mar- 

 gined. 317. ULIGINOSUS. 

 cc. Elytra broadly pale margined. 317b. var. lateralis. 

 aa. Head light reddish-brown or testaceous ; pronotum and elytra broad- 

 ly pale margined, the latter sometimes entirely pale. 



317c. var. limbatus. 



317a (502b). Geocoris uliginosus speculator Montandon, 1908, 227. 



Differs from the typical form only in the color characters given in 

 key and by having the legs of female wholly pale brownish-yellow. Form 

 somewhat more robust. Length, 3.3 — 4 mm. 



Marion Co., Ind., June 16. Ranges from Massachusetts to 

 British Columbia, California and Texas. 



317b (502c). Geocoris uliginosus lateralis (Fieber), 1861a, 271. 



This variety hardly deserves a special name, the only difference be- 

 tween it and typical uliginosus being in the relative width of the pale 

 margin of elytra. Specimens with all degrees of this width occur, so 

 that the two forms intermerge wherever found. 



Southern half of Indiana, frequent, July 11 — Dec. 3. Dune- 

 din, Fla., March 16. Occurs with the typical form throughout
