edges of open woodlands. It is more frequent in bottom lands than in 
more elevated tracts. 
July 27, frequent in grassy and sedgey spots in bumid upland woods 
(1); August 9, in small numbers in low woods and thickets along Bur- 
nett Creek (2); August 20, occasional in a low field along the outer edge 
of the Wabash bottom near West Lafayette (6) occurring in Tridens flava 
and Elymus virginicus; September 6, occasional in the undergrowth on a 
wooded slope near a Hom«locenchrus oryzoides marsh (10); September 
13, a female taken in low woods along Burnett Creek (2). 
Chiealtis conspersa Harris. Occasional in grassy spots in damp wood- 
lands; very local. 
July 27, several males and one female observed in humid upland 
woods northwest of West Lafayette (1), in a grassy clearing where the 
preyailing herbaceous vegetation consisted of Carer, Elymus and Hystrix ; 
September 13, a single male taken in low woods along Burnett Creek (2), 
at the edge of a cat-tail bog. 
Stauroderus (Stenobothrus) curtipennis (Harris). Apparently only 
moderately frequent and rather local, occurring in humid tracts well coy- 
ered with succulent grasses. 
July 19, in small numbers in the bottoms near the mouth of Wild Cat 
Creek (11), in dense growth of Hlymus virginicus; August 12, a female 
taken in patch of fox-tail (Chetochloa viridis) in a waste lot on the Pur- 
due Experimental Grounds (3); July 12, a small colony in a moist grassy 
depression along the edges of woodland on the upland between Lafayette 
and Montmorenci (12); September 6, quite scarce in grassy areas on a 
wooded slope south of Wild Cat Creek (10). 
Arphia sulphurea (Fabricius). Found only once in late April in a 
sparse growth of blue grass (Poa pratense) at the top of a high bluff at 
Happy Hollow (5). It was at this time in the nymph stage. No others 
were observed during the season, but it is doubtless more frequent in the 
spring months than my very meagre field observations made at that sea- 
son would indicate. 
Arphia canthoptera (Burmeister). Frequent in untilled areas in nu- 
merous dry situations, chiefly in upland localities. Both yellow-winged 
and orange-winged examples occur in nearly equal numbers. The species 
appears to occur only occasionally on fully cultivated land. 
August 1, frequent on the bluffs at the head of Happy Hollow (5); 
occurring in dry grassy areas and on bare ground on the gentle inclines
