THE RED-BUG FAMILY. 



443 



tarsi piceous. Side margins and collar of pronotum and costal margin 

 of corium broader and more refiexed than in our other species. Length, 

 11—18 mm. 



Orizaba, Mexico, July (W. S. B.) ; common on foliage and 

 flowers in gardens and moist waste places. Biscayne Bay, Fla., 

 Slosson Coll. Described from Mexico and known in this coun- 

 try also from Texas, Arizona and California. Uhler (1876, 

 314) states that "in some varieties the head, pronotum and 

 corium are entirely black and from this to a variety with only 

 a point of black on middle of corium, every phase occurs." In 

 two of the examples at hand the ventral segments are almost 

 wholly ivory-white, in others largely brown or red. Stal (1854, 

 236) described Say's typical form as D. albidiventris and limited 

 Say's name to the two varieties mentioned by Say, a proceed- 

 ing not in accordance with the ethics of present day nomencla- 

 ture. His flavo-limbatus (1861, 198) appears from the descrip- 

 tion and Distant's figure to be the same as Say's var. a and his 

 two names, as well as Distant's obscuratus will in time probably 

 be found to apply only to color varieties of Say's species. 



400 (633). Dysdercus suturellus (Herrich-Schaeffer) , 1842, 76. 



Elongate, narrowly oval. Ground color bright to dull red ; disks 

 of hind lobe of pronotum, clavus and corium dark brown ; collar of prono- 

 tum, narrow margins of clavus and costal 

 and apical margins of corium yellowish- 

 white; membrane dark brown, the narrow 

 apical margins pale; antenna? piceous- 

 brown, the extreme base red; femora red, 

 the tibiae, tarsi and apical joint of beak 

 piceous-black. Pronotum with side mar- 

 gins strongly refiexed ; disk of hind lobe, 

 as well as those of clavi and elytra, sparsely, 

 finely, shallowly punctate. Length, 12 — 17 

 mm. (Fig. 94). 



Lakeland, Utopia, R. P. Park, Moore 

 Haven, Ft. Myers, Cape Sable, Caxam- 

 bus and Dunedin, Fla., Nov. 22 — Aug. 

 5 (W.S.B.). Recorded from numer- 

 ous other stations and doubtless found 

 throughout the State. Occurs in 

 colonies on foliage of wild Hibiscus, 

 cotton and other Malvaceae, and also attracted to light. Known 

 as the "cotton-stainer" or "red-bug," and does much damage to
