142 FAMILY V. — PENTATOMID.-E. 



numerous very irregular smooth spaces intervening. Scutellum with 

 similar transverse smooth markings, its marginal punctures near base 

 much coarser. Connexivum narrowly exposed, male, more broadly so, 

 female. Abdomen alutaceous and finely, evenly, not closely punctate. 

 Male genital plate appearing as if pinched, its median line with an 

 obtuse ridge, its sides concave; hind margin subtruncate or slightly 

 sinuate. Length, 10.5 — 11.5 mm.; width, 6 — 6.5 mm. 



Dunedin and Sarasota, Fla., Nov. 17 — April 12. Frequent 

 about Dunedin in the fall and spring on weeds and low shrubs 

 in open pine woods. Hibernates beneath bark and amongst the 

 roots of tufts of grass. Described from St. John's Bluff, Fla., 

 and recorded by Barber from seven other stations in the State. 

 Known only from Georgia, Florida and North Carolina. 



X. Hymenarcys Amyot & Serville, 1843, 124. 



Small or medium sized Pentatomids having the head porrect, 

 as long as or longer than wide, tylus strongly convex, equalling 

 the cheeks; antennas slender, not surpassing base of prono- 

 tum ; beak reaching beyond middle coxae, its first and second 

 joints subequal in length, third and fourth shorter, also sub- 

 equal ; pronotum with front portion gradually declivent, its 

 humeral angles rounded, not prominent ; scutellum relatively 

 long, its apex rounded and almost reaching that of corium, 

 the latter with apex straight, oblique, its outer angle acute; 

 membrane equalling or but slightly surpassing tip of abdomen ; 

 tibiae sulcate ; osteolar opening without a canal, its auricle very 

 short. Genital plate of males broad, concave each side, the 

 hind margin broadly rounded, feebly sinuate. 



In this genus and Menecles the scutellum becomes wider be- 

 hind, the apical third being almost as wide as that of corium, 

 with tip more rounded than in preceding genera, thus ap- 

 proaching those genera under dd of the generic key, in which 

 the tip of scutellum is wider than and surpasses that of corium. 

 Hymenarcys is represented by but four known species, all con- 

 fined to North America, two of them occurring in Mexico and 

 the southwestern states, the others in our territory.
