Laporte, Marion and Vigo counties, Ind., Aug. 5 — Oct. 16. 

 Swept from tall grass on the former date, taken from beneath a 

 log on the latter. This appears to be one of the scarcer Penta- 

 tomids in Indiana, but six specimens being at hand. Its known 

 range is a wide one, extending from Quebec and New England 

 west to British Columbia and Montana and south and south- 

 west to Oklahoma (and Texas?). Van Duzee (1904,49) states 

 that — "Its southern range includes Florida and Texas," but I 

 have not taken it in Florida nor does Barber record it from 

 there. In fact, the most southern previously definitely men- 

 tioned stations are "Ft. Cobb, Indian Territory," by Uhler 

 (1872, 396) and various points in New Jersey by Smith (1910, 

 135). However Brimley (Ms.) reports it from Blowing Rock 

 and Grandfather Mountain, N. Car. 



Of its habits Van Duzee (1894, 171) says that about Buf- 

 falo, N. Y., it is "common in dry fields and pastures throughout 

 the season. In September I found a dozen or more individuals 

 gathered on a bruised sweet apple, the juice of which they were 

 eagerly imbibing." Olsen (1912, 53) states that he has kept 

 the adults in captivity for two months by feeding them on 

 moth mullein. Stoner (1920, 88) mentions its habits in Iowa 

 as follows: 



"Timothy and clover fields, particularly those in more or less moist 

 situations, are the places most frequently chosen by this insect. The 

 vegetation of semi-cultivated roadsides will frequently harbor it in some 

 numbers, especially if there is more or less timothy and blue grass 

 present. Low-lying blue-grass pastures are also favored habitats. Hiber- 

 nating forms are not uncommon, and specimens may be found in early 

 spring under boards, sticks and rubbish in pastures and along the grassy 

 edges of fields. Judging from the material at hand, this species breeds 

 rather later in the year than most of our Pentatomids, and with us ap- 

 pears to be single brooded. All the nymphs have been taken in July."
