SUBFAMILY I. — LYG^INiE. 341 



other Compositae in the latter months. Dunedin and Live Oak, 

 Fla., Jan. 10 — April 8; Orizaba, Mexico, July {IV. S. B.). About 

 Dunedin it occurs in company with the showy Coreid, Sephina 

 grayi Van D., and a small gray beetle, Monced'us guttatus Lee, on 

 a very slender-stemmed climbing milkweed, Metastelma scoparium 

 Nutt. This plant grows only in dense wet hammocks where it 

 forms great masses on the shrubby undergrowth. By beat- 

 ing these masses in March and April one is pretty certain of 

 getting all three of these insects, they being the only ones com- 

 monly found on the plant. The known range of 0. fasciatus is 

 a very wide one, extending from Massachusetts westward over 

 the greater part of the United States east of the Rocky Moun- 

 tains and south and southwest to Florida, Texas, California, 

 Mexico and Brazil. It has been recorded from numerous sta- 

 tions in Florida and doubtless occurs throughout that State. 

 The hosts of 0. fasciatus, as well as that of several species of 

 Lygccus, are different species of milkweed, and it is very doubt- 

 ful if the young prey upon the plants of any other family. 



274 (433). Oncopeltus sex-maculatus Stal, 1874, 102. 



Elongate-oval. Black; front half of pronotum with a large sub- 

 triangular orange-yellow spot each side; elytra each with a large oblong 

 spot at base and a second oblique one near apex of corium, dull red; pro- 

 sternum, osteolar canal, spot on hind margin of mesopleura and sides of 

 first four ventrals orange to dull yellow. Front portion of pronotum 

 with a large, deep, irregular impression each side, this enclosing a nar- 

 row, curved, more deeply impressed line. Head sparsely pilose, side 

 margins of pronotum and corium densely so. Other characters as in 

 generic description and key. Length, 10 — 12 mm. 



Moore Haven, Caxambus, Chokoloskee and Cape Sable, Fla., 

 Feb. 23 — April 5. Taken by sweeping along the mucky mar- 

 gins of lakes and beating in dense hammocks. A Mexican and 

 Central American species recorded by Barber from Lake Worth 

 and Miami, Fla. That part of Stal's description : "maculis ob- 

 soletis duabus oblongis ante medium capitis testaceis ; macula 

 membranae albida," does not hold good of the Florida speci- 

 mens, as they have the head and membrane wholly black. 



II. Lyg^US Fabricius 1794, 133. 



Oblong or oblong-oval bicolored species of medium or small 

 size having the head and antennae much as in Oncopeltus; beak 

 reaching to or beyond middle coxae; pronotum subtrapezoidal, 

 more or less punctate and transversely impressed near middle,
