510 FAMILY XVII. — PHYMATID^E. 



sides rounded, disk granulate; hind lobe much wider, its disk uneven, 

 thickly, rather coarsely punctate, the carinas divergent behind. Median 

 callosity of scutellum with apical half widened and flattened, its apex 

 subtruncate with angles and middle usually slightly prolonged, the 

 latter continued as a fine carina to apex of scutellum. Connexivum of 

 female more widely expanded and exposed than in male. Length, 

 9—11 mm. 



Dunedin and R. P. Park, Fla., Jan. 20 — April 11. Frequent 

 at Dunedin in open pine woods in early spring on the flowers 

 of low shrubs, especially those of a dwarf pawpaw, A simian 

 parviflora Michx., and a low huckleberry, Vaccinia myrsinites Lam. 

 Nymphs were taken only once, Nov. 23, on the huckleberry 

 mentioned. The adults hibernate on the under side of leaves 

 or dead weeds which afford them protective coloration. 



The known range of M. cimicoides extends from "Carolina" 

 and Florida west to Texas and California. In Florida it has 

 been recorded from several stations between Jacksonville and 

 Ft. Myers and doubtless occurs sparingly over most of the 

 State. When fresh the basal half of pronotum and the scutellum 

 are often a handsome reddish-purple and the callosity of the 

 latter sometimes blue. This varied hue taken in connection 

 with the peculiar shape and large front legs make this one of 

 the most bizarre forms of our Heteropterous fauna. 



486 (695). Macrocephalus prehensilis (Fabricius), 1803, 123. 



Elongate-oval. Dull yellow or greenish-yellow; upper surface with 

 head, pronotum and a wide median stripe the full length of scutellum, 

 blackish; antenna? brown; tibiae and tarsi greenish-yellow. Antennae 

 much as in cimicoides, joints 2 and 3 subequal, the third subclavate. 

 Pronotum with disk much less uneven and more flattened than in cimi- 

 coides, thickly and deeply punctate, the margins of front lobe rather 

 sharp, and granulate. Carina of scutellum narrow, of equal width 

 throughout, its pale basal calloused portions very short. Length, 

 5 — 5.5 mm. 



Dunedin, Fla., April 10 — 18. Three taken singly by sweep- 

 ing low vegetation along the margins of ponds. Recorded by 

 Barber from ten other stations in the State. Ranges from 

 "Carolina," Kentucky and Tennessee, south and southwest to 

 Texas and Mexico. 



The Macrocephalus manicatus (Fabr.) listed from "Carolina" 

 and Texas by Van Duzee (1917, 230) was regarded by Stal as 

 a synonym of cimicoides. The locality "Amerique du Nord," 

 cited by Handlirsch (1897, 193) for his M. gracilis, is too in- 

 definite for the insect to be included in this work.
