equalling tylus, their margins feebly sinuate in front of eyes ; 

 beak as in generic key ; antennae slender, nearly half the length 

 of body, joints 2 — 5 subequal; pronotum long, strongly tapering 

 from the humeri forward, the front portion but little declivent, 

 its side margins straight, very finely crenulate, humeri promi- 

 nent, ending in an oblong spine, its tip subtruncate, slightly 

 bifid ; apical half of scutellum narrower than corium, its tip 

 broadly rounded; apex of corium straight, oblique; membrane 

 slightly surpassing abdomen, its veins few, simple ; connexivum 

 broadly exposed ; second ventral and front femora unarmed ; 

 tibiae deeply sulcate above, the front ones dilated toward apex. 

 Genital plate of male narrow, convex, its hind margin broadly, 

 shallowly emarginate, with a semicircular concavity in front of 

 the angle of the notch. 



Two species are known, one from Brazil, South America, the 

 other also neotropical but extending northward into our terri- 

 tory. 



134 (220). Euthyrhynchus floridanus (Linnaeus), 1767, 719. 



Elongate-oval, subconvex. Above purplish- or bluish-black, feebly 

 shining; pronotum usually concolorous, sometimes with front and side 

 margins, a broad stripe at base of humeri and a median one, red; scu- 

 tellum with a large spot each side of base and the apex red; connexivum 

 with alternate black and red spots; under surface blue-black, with a 

 broad median reddish or yellow stripe, extending from front coxas to 

 first or second ventrals; legs blue or blue-black, beak and base of 

 femora reddish-yellow. Cheeks finely, closely, confluently punctate; 

 tylus and two lines on occiput almost smooth. Pronotum finely, rather 

 sparsely, quite evenly punctate, its front portion with several vague 

 broad impressions. Elytra and scutellum evenly punctate, the former 

 much more finely and sparsely so. Abdomen very finely granulate and 

 with minute widely scattered punctures. Thoracic pleura coarsely, 

 deeply, sparsely punctate. Structural characters as in generic descrip- 

 tion. Length, 12 — 17 mm.; width, 6.5 — 8 mm. 



Sanford, Istokpoga and Dunedin, Fla., Nov. 21 — April 12 

 (W. S. B.). Agricultural College, Miss. (Weed). Recorded from 

 a number of other stations in Florida and probably occurs spar- 

 ingly throughout the State. About Dunedin it is found in late 

 autumn on the flowers of the shrubby Compositae, Garberia 

 fruticosa (Nutt.), and in spring on the foliage of shrubs along 

 the borders of hammocks. North of Florida it has been re- 

 corded in this country from Pennsylvania, Georgia, North 

 Carolina, Tennessee and Louisiana. Van Duzee (1904, 73)
