SUBFAMILY I. — PENTATOMIN^E. 153 



Ridgeway, Ontario, he once found them mating, May 31, on 

 wild columbine and that they were present in such numbers 

 as nearly to cover the plants. Hart (1907, 238) mentions it 

 as occurring at Havana, 111., "on Scrophularia nodosa and other 

 plants among the black-jack oaks, clustered along the stems." 

 Olsen (1912, 54) has bred it from egg to imago on moth 

 mullein and states that "a male has been observed to prey upon 

 the eggs deposited by its mate, completely draining their con- 

 tents." Other food plants which have been mentioned by 

 authors are Ranunculus, currant, blackberry, mint, potato, 

 raspberry, thistle, nettle and pokeberry.

 acute and separated ; beak reaching to or beyond middle of 

 third ventral, its first joint longer than bucculae, second almost

 ly crenulate ; humeral angles prominent, acutely produced in an 

 upward and outward projecting spine ; scutellum with apical
