SUBFAMILY I. — PENTATOMIN^E. 97 



g. Head produced and triangular in front of sinus of cheeks, the 

 tooth of latter prominent; connexivum with alternate pale and 

 black spots; length not over 18 mm. 60. carolinensis. 



gg. Head but little if at all produced in front of its lateral sinus, 

 the latter either wanting or with tooth obtuse. 

 h. Length, 15 — 17 mm.; lateral sinus of cheeks obsolete; con- 

 nexivum conspicuously alternated with black and red. 



61. PUNCTATA. 



hh. Length, 20 or more mm.; lateral sinus evident, its tooth blunt; 



connexivum fuscous with incisures and entire outer edge dull 



yellow. 62. marginella. 



54 (81). Brochymena arborea (Say), 1825, 311; II, 239. 



Broadly oval, subdepressed. Dull brownish-yellow thickly marked 

 with fuscous punctures ; pronotum with a fuscous blotch in each ante- 

 apical depression; elytra and scutellum with a few small scattered ele- 

 vated smooth yellow spots ; each segment of connexivum with a blackish 

 crossbar across the ends, the middle pale; under surface and legs dull 

 yellow, the latter annulate with black. Head with cheeks passing the 

 tylus but not incurved in front of them, subapical sinus deep, rounded, 

 the teeth prominent, triangular, directed forward and outward; joints 

 3 — 5 of antennae subequal in length, each one-third longer than second. 

 Front side margins of pronotum with four or five rather large triangular 

 teeth and one or two smaller ones between them. Scutellum with a low 

 median lengthwise ridge, the tip bluntly rounded and impressed. Paired 

 basal plates of female genital segment strongly convex, declivent be- 

 hind. Length, 12 — 17 mm.; width, 8 — 10 mm. 



Frequent in the southern half of Indiana, April 29 — Oct. 20; 

 not taken by me in the northern counties. Beaten from foliage 

 of wild grape and apple and taken Oct. 20 from beneath bark 

 of oak log. Dunedin, Moore Haven and R. P. Park, Fla., Nov. 

 17 — April 13 (W.S.B.). Recorded also from numerous other 

 points in that State. Both adults and nymphs were beaten 

 from cypress at R. P. Park in December. Its known range ex- 

 tends from Ontario and New England west to Kansas and 

 southwest to Florida, Texas and Old Mexico. In the north it 

 appears to be most frequent in wooded hilly regions and may 

 often be noted in late autumn sunning itself on the boles of 

 oak, beech and other trees with whose bark it harmonizes in 

 hue. In this species and the next the abdomen appears to sud- 

 denly widen opposite the middle of scutellum, the connexivum 

 being from there on apparently wider and more exposed than 

 in the species under act. of the key. 



55 (83). Brochymena poeyi (Guerin), 1857, 365. 



Form of arborea, averaging somewhat larger. Above pale grayish- 

 yellow marked with fuscous punctures which are aggregated to form
