CANTHOPHORUS, Muls. and Rey. 



7. C. cinctus, Pal. Beauv. 



July to .Sept. May be taken in low weedy fields and along 

 fence rows. Not common. 



FAMILY PENTATOMIDAE. 



PERILLUS, Stal. 

 S. p. circumcinctus, Stal. 



Occurs on coarse weeds and on bushes and trees in July and 

 August. Also taken in January hibernating in dead leaves 

 and grass. 



PODISUS, H. .Sch. 



9. P. cynicus, Say. 



Occasional on willows and other trees and bushes in July, 

 August and Sept. One specimen taken by Mr. Kilman at 

 Ridgeway measures 20 mm. in length. I once found a large 

 individual of this species with its beak deeply inserted in a 

 fully grown larva of Platysamia cecropia which it seemed to 

 imagine it could hold by bracing itself and pulling back with 

 all its strength! The caterpillar did not appear at all disturbed 

 and possibly the bug might have eaten its fill without inflict- 

 ing serious injury on its victim. 



10. P. spinosus, Dallas. 



Common. May to Sept., and in January hibernating. 



11. P. modestus, Dallas. 



May to September. Sometimes abundant on trees infested 

 with scale-insects and plant lice. 



PODOPS, Laporte. 



12. P. cinctipes, Say. 



May to Sept. Swept from swamp grasses in low weedj' 

 pastures. December under leaves at the park. 



BROCHYMENA, Am. and Serv. 



13. B. arborea, Say, 



Sept. Occasional on trees especially of birch. Taken hiber- 

 nating early in April. 



14. B. quadripustulata, Fabr. 



July and Sept. Lancaster, on hickory and american aspen. 



NEOTTIGLOSSA, Kirby. 



15. N. undata, Say. 



May to Sept. 



COSMOPEPLA, Stal. 



16. C. carnifex, Fabr. 



Generally abundant everywhere throughout the season but 

 like the next they seem especially fond of the mullen. I once 

 observed a remarkable gathering of these pretty insects on a 

 wild columbine at Ridgeway Ont., on the 31st of May. They 

 were present in such number as nearly to cover the plants and 

 were pairing, which was apparently the object of the meeting.
