SUBFAMILY I. — PENTATOMIN^E. 149 



tellum, edge of side margins of pronotum and connexivum and a short 

 calloused line on each basal angle of scutellum, pale yellow; antenna? 

 reddish-yellow, the last two joints fuscous; thoracic pleura dull yellow, 

 thickly marked with coarse black punctures; legs yellow, the femora with 

 purplish dots; abdomen piceous, feebly bronzed, finely and evenly punc- 

 tate, its side margins yellow. Head convex, its side margins smooth and 

 apex subacute; cheeks usually meeting in front of tylus, the latter with 

 a few coarse punctures. Third antennal three-fourths the length of 

 second. Pronotum with scattered small irregular spots and narrow 

 transverse lines smooth; otherwise rather evenly punctate. Hind mar- 

 gin of genital plate of male with a small median notch. Length, 4.5 — 

 5.5 mm.; width, 3 — 3.5 mm. 



Lake and Marion counties, Ind., June 4 — Sept. 1 ; swept from 

 grass along roadsides in low alluvial soil. Elizabeth and St. 

 Joseph, 111., June 27 — July 7 (Hart). Apparently a scarce 

 species in Indiana. Ranges from Quebec and New England 

 westward across southern Canada and the northern states to 

 the Pacific ; the only record of its occurrence south of New Jer- 

 sey and central Illinois being that of Bueno for Southern Pines, 

 N. Car. Of its occurrence and habits in Iowa Stoner (1920, 

 93) has written: "Common in suitable situations and in some 

 seasons even abundant under favorable conditions. Almost 

 any field of timothy or blue-grass will yield numbers of these 

 bugs during the summer months. Specimens are also some- 

 times taken from red clover, mullein and riverside grape. 

 Adults are most common in July. Hibernating individuals 

 have been found in March and April under rocks in out-of-the 

 way places which have been permitted to grow up in weeds and 

 grass during the summer."

Larger than undata, to which it is closely allied. Head and front 

 half of pronotum black; elytra and basal half of pronotum dull yellow 

 with fuscous punctures ; median line of pronotum and a small spot be- 

 hind each callosity yellow, side margins white. Scutellum testaceous, 

 basal angles and a spot on apex blackish, disk with a median yellow line 

 extending from base to apical third, this crossed at middle of scutellum 

 by a transverse yellowish line which unites with a sublateral line each 

 side, extending to base of scutellum, thus forming a trident marking. 

 Corium with two piceous spots on apical margin; membrane and connexi- 

 vum white; dorsum black; under surface bronzed-black, closely punctate; 

 legs yellowish, femora and tibiae with black lines or spots ; third tarsal 

 joint piceous. Head less abruptly deflexed with apex less acute than in 

 undata. Third antennal relatively longer, only one-ninth shorter than 

 second. Beak nearly reaching hind coxae. Pronotum with side margins
