LIFE-HISTORY NOTES ON TWO FULGORID/E.

I. Amphiscepa bivittata Sa}-. 



August I, 1902, while sweeping \vith the insect net amongst 

 tall grass, wild balsam and other weeds, at Cedar Point, Sandusky, 

 Ohio, several innnature insects were secured, that later proved to 

 be the larvae of Amphiscepa bi\-ittata Say. One adult was dis- 

 covered upon a grass blade within one-fourth inch of the exuvia' 

 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 larva 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. They 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.
