d. Second and third joints of antennae not thickened, the second 

 nearly three times as long as third. 353. minima. 



dd. Second joint of antennae less than twice as long as third, antennal 

 joints gradually increasing in thickness from the base of sec- 

 ond. 354. ANTENNATA. 

 aa. Front lobe of pronotum twice or more the length of hind one; fore 

 tibiae of male armed with a distinct preapical tooth; joints 2 — 4 

 of antenna? furnished with stiff erect hairs. (Subgenus Carpilis 

 Stal). 

 e. Second and third joints of antennae distinctly more slender than 

 fourth; pronotum (brachypterous form) with front lobe sub- 

 globose, its sides rounded, hind lobe wholly pale, its angles feebly 

 nodulose above. 355. ferruginea. 

 ee. Third joint of antennae and apical half of second as stout as fourth; 

 pronotum (brachypterous form) with front lobe subcylindrical, 

 its sides almost straight, hind lobe dark reddish-brown, its angles 

 pale, strongly nodulose above. 356. barberi. 



351 (557). Ptochiomera nodosa Say, 1832, 18; I, 335. 



Oblong. Head, front lobe of pronotum, scutellum except carina, 



third joint of antenna? and basal half of fourth, dark brown or piceous; 



narrow front margin and hind lobe of prono- 

 tum and disk of corium and clavus dull 

 straw-yellow marked with numerous fuscous 

 punctures; membrane hyaline, its veins 

 paler; first and second joints of antenna?, 

 legs and beak, pale yellow; under surface 

 dull yellow, the sides of abdomen usually 

 darker. Antennae with last two joints very 

 stout, the fourth fusiform, slightly longer 

 and more slender than third; second slender, 

 subclavate, a little longer than third. Prono- 

 tum with front lobe one-half longer and dis- 

 tinctly narrower than hind one, its disk 

 minutely, densely punctate; hind lobe with 

 angles carinate, disk rather coarsely and 

 evenly punctate. Scutellum with transverse 

 ridge angulate, both it and carina prominent; 

 disk otherwise finely densely punctate. 

 Brachypterous forms with front lobe of 



pronotum relatively longer, membrane very short or obsolete, corium 



reaching base of fifth dorsal. Length, 3 — 3.5 mm. (Fig. 86). 



Frequent in the southern half of Indiana, much less so in the 

 northern counties. Occurs throughout the year, hibernating 

 beneath chunks and rubbish and in bases of tufts of grass along 

 the margins of cultivated fields and roadsides, and in spring 

 and summer taken by sweeping herbage along roadsides and in
