106 FAMILY V. — PENTATOMID^. 



purse, Bursa bursa-pastoris L. Hibernates in winter beneath 

 logs, mullein leaves, the bottom rails of old fences and other 

 convenient hiding places. Ranges from Ontario and New Eng- 

 land west across the continent and southwest to Georgia, Texas 

 and Old Mexico. Not as yet recorded from Florida, though it 

 probably occurs in the northern portion of that State. The 

 upper surface varies considerably in hue, some specimens being 

 very dark, due to the greater density of the fuscous punctures. 

 In two examples at hand from Mississippi the cheeks, while 

 longer than tylus, are not contiguous in front of it. 



Of its occurrence in Illinois, Hart (1919, 185) says: "It is 

 particularly a late summer and fall species. We have taken it 

 in January, March, April and May, but especially from June 

 19 to Nov. 7, the largest number of captures being in October. 

 The nymphs were taken during the summer months. At 

 Urbana, Oct. 26, twenty-three adults were found on a single 

 cauliflower stalk with their beaks inserted, evidently sucking 

 the sap." Zimmer (1911,223) states that in Nebraska : "This 

 is our most common Pentatomid in the eastern part of the 

 State. In autumn it is almost impossible to sweep a patch of 

 grass or weeds without getting a net full of these insects." 



64 (96). Peribalus piceus (Dallas), 1851, 236. 



Oval, subconvex, broadest behind the middle of abdomen. Above 

 dull brownish-yellow, thickly marked with piceous punctures, those on 

 head, front of pronotum and basal half of scutellum larger and more or 

 less confluent, causing these parts to appear almost black in hue; pale 

 border of pronotum narrower, and that on apex of scutellum smaller 

 than in limbolarius; segments of connexivum black with narrow pale 

 outer edge and median square dull reddish spot. Under surface piceous, 

 paler along the middle, the middle of lateral margin of each ventral 

 reddish-yellow; legs dull yellow with piceous dots and blotches. Cheeks 

 with side margins distinctly sinuate in front of eyes, their tips longer 

 than tylus, their surface coarsely rugosely and confluently punctate. 

 Pronotum with a distinct but ill-defined median transverse groove, the 

 front portion more convex and less declivent than in limbolarius; disk 

 with humeral angles subacute, and with a wide rather deep submarginal 

 impression each side. Scutellum with apical two-thirds wider and less 

 tapering behind than there. Male with genital plate longer, almost 

 perpendicular, its ends with a shallow U-shaped emargination, the result- 

 ing lobes short and broadly rounded. Length, 8.5 — 9 mm.; width, 

 5.2 — 5.5 mm.

 probably occurs in northern Indiana. Known elsewhere from
