I. Amphiscepa bivittata Say. 
August i, 1902, while sweeping with the insect net amongst 
tall grass, wild balsam and other weeds, at Cedar Point, Sandusky, 
Ohio, several immature insects were secured, that later proved to 
be the larvae of Amphiscepa bivittata Say. One adult was dis- 
covered upon a grass blade within one-fourth inch of the exuviae 
of one of the larvae, and it looked fresh, as though it had 
but recently assumed its mature form. Several larvae were taken 
home alive and placed upon grass in a bell-jar ; and within a week 
they had all transformed to the adult stage, thus proving the 
identity of the larvae ; in fact, I was so fortunate as to observe 
one specimen in the act of moulting, on the morning of August 4th. 
August 2d and August 8th larvae were taken from golden rod 
and other weeds along a hedge fence enclosing a clover field, 
about three miles southeast of Sandusky ; but none were taken 
later than that date ; adults were taken in considerable numbers, 
however. 
Few specimens were found at rest on the plants, but from the 
ones that were found, it would seem that they habitually perch 
upon a stem just below the base of a petiole (VI-5), and there 
puncture the stem to secure the sap for food. In this position 
they have some resemblance to the tufts of hairs often found at 
base of petiole or in the axil. The}' are very active when dis- 
turbed. leaping about as suddenly as the adults do, but may 
often be secured by quickly putting the mouth of the killing 
bottle over them before they leap. 
DESCRIPTION OF LARVA. 
Length 4 mm.; breadth 2 !4 mm.; back very convex, so that height 
nearly equals breadth ; general color whitish with brown markings ; head 
broad, nearly straight across in front, slightly incurved in middle, prominent 
marginal carina in front of eyes ; vertex twice as broad as long, whitish, 
with a median darker stripe ; frous darker at base, some white dots in this 
darker area, a row of dark-centered pustules near each margin ; clypeus 
and beak dark brown ; eyes pale brown with a few lighter areas ; first 
segment of antenna very short, second segment subglobose, bristle black, 
enlarged at base ; peronotum slightly shorter than vertex, broader behind 
the eyes, white median carina, bordered on each side with a darker stripe, 
which is a continuation of the median stripe of vertex, and extends the 
whole length of thorax and abdomen ; a dark brown spot on pronotum 
behind the eye, remainder of pronotum whitish, nearly covered with black- 
centered pustules ; mesonotum twice as long as pronotum, whitish, dotted 
with black, a dark brown area at base of wing pads, at each outer anterior
