152 FAMILY V. — PENTATOMIDiE. 



rounded; frena in our species less than one-half its length; 

 membrane hyaline, slightly surpassing abdomen, its veins 

 simple; connexivum narrowly exposed; osteolar opening with 

 auricle very small, scarcely evident ; tibiae not sulcate. Genital 

 plate of male short, broad, its hind margin subtruncate and re- 

 flexed. 



Seven species are known from the American Continent, five 

 of which occur in the United States, but only one is definitely 

 known from our territory. ; - 



102 (149). Cosmopepla bimaculata (Thomas), 1865, 455. 



Broadly oval, convex above and beneath. Black, shining; pronotum 

 with edge of side margins, a transverse line be- 

 tween the humeri and a narrower longitudinal 

 median line, reddish-yellow; apical third of 

 scutellum with a large triangular red spot each 

 side; edge of side margins of abdomen and of 

 basal third of elytra yellow or reddish-yellow; 

 tarsi piceous. Head as wide across the eyes as 

 long, its apex rounded ; cheeks flat, densely and 

 coarsely punctate, their margins slightly sinu- 

 ate. Pronotum with black portion closely rather 

 coarsely punctate, the pale lines and edges 

 smooth. Scutellum coarsely punctate with nu-

 (After Lugger). merous smooth lines intervening on basal half. 



Elytra coarsely somewhat rugosely punctate. 



Abdomen finely and rather sparsely punctate, the thoracic pleura more 



coarsely and densely so. Length, 5 — 7 mm.; width, 3 — 4.2 mm. (Fig. 29). 



Common throughout Indiana, May 5 — Oct. 16. Occurs on 

 the foliage and flowers of many plants, especially those of oats, 

 mullein, bouncing-bet, greater ragweed and goldenrod. Found 

 mating on May 5 and June 19. Ranges from Nova Scotia and 

 New England, west to British Columbia and Washington, and 

 south to Georgia, Texas and Mexico. Not as yet recorded from 

 Florida, though it possibly occurs in the northern third of that 

 State. It has been generally known as C. camifex (Fabr.), but 

 Kirkaldy (1909, 80) showed that that name was preoccupied 

 and renamed it C. lintneriana. Thomas, however, had previously 

 described it (loc. cit.) as Pentatoma bimaculata. 



This prettily colored little bug appears to be abundant over 

 much of its wide range. Van Duzee (1894, 170) states that at 



"Montandon (1893, 19) says that he 1ms seen a specimen of C. binotata Hist.. 

 from Wisconsin, in the Lethierry collection. As it is known elsewhere only from 

 Mexico .mil Arizona, it was probably wrongly labelled or an adventive.
