SUBFAMILY I. — PENTATOMIN^E.

nal ridge ; osteolar canal tapering into a long curved ridge. 

 Hind margin of genital plate of male with a broad median U- 

 shaped notch. 



Stal (1872, 49) lists no fewer than 115 described species of 

 this genus, all from tropical Central and South America and 

 Mexico, and many of them doubtless synonyms, as only 68 of 

 them were known to him and separated by his keys. Of these 

 but one occurs in the United States and our territory. 



124 (202). Edessa bifida (Say), 1831a, 7; I, 303, 322. 



Broadly oval, subconvex above, convex beneath, obtusely rounded 

 behind. Above greenish-olive, the elytra and apical half of scutellum 

 tinged with reddish; head and front portion of pronotum with some 



smooth yellowish areas; tip of 

 scutellum and narrow edges of 

 side margins of pronotum yellow; 

 membrane fuscous ; connexivum 

 green, often obscurely mottled 

 with yellow; antennae reddish- 

 yellow, the last two joints dusky; 

 under surface and legs yellow, the 

 abdomen sometimes with two 

 vague fuscous stripes each side. 

 Cheeks wide, feebly concave, each 

 with a few coarse punctures and 

 fine oblique grooves. Pronotum 

 coarsely, very sparsely and un- 

 evenly punctate, the front por- 

 tion with a few transverse sub- 

 calloused smooth lines. Scutellum 

 median ridge of meta- coarsely and very sparsely punc- 

 tate, more closely so on apical 

 third, the yellow tip smooth. Elytra minutely alutaceous, finely, evenly 

 and rather closely punctate. Under surface rather coarsely and very 

 sparsely punctate, the low median lengthwise ridge of abdomen smooth. 

 Length, 13—15 mm.; width, 7—8.5 mm. (Fig. 35). 



Dunedin, Sanford, Moore Haven, Ft. Myers, R. P. Park and 

 Cape Sable, Fla., Dec. 12 — April 4; Orizaba, Mexico, July 28 

 (W. S. B.). Recorded by Van Duzee and Barber from a dozen 

 or more additional localities in Florida and doubtless occurs 

 sparingly throughout that State. Known elsewhere in the 

 United States only from Louisiana and Texas, Say's types being 

 from the former State. My specimens were mostly taken by 

 sweeping low shrubs along the margins of ditches and streams ; 

 the two from Dunedin on grasses of tidewater marshes. Uhler
