Lopidea robiniae Uhler (Plate III). 



On June 10, 1915, a number of reddish, first-stage Capsid 

 nymphs, with a white band at the base of the abdomen, were 

 observed on the leaves of the common locust, Robinia pseudo- 

 acacia L., at Honeoye Falls, New York. On June 21, third 

 and fourth-stage nymphs were obtained, and on June 26, the 

 first fifth-stage nymph was observed. July 7 fifth-stage 

 nymphs were very common and on July 10 two adults were 

 taken in company with the nymphs. These were kindly deter- 

 mined for me by Mr. H. H. Knight as Lopidea robiniae Uhler. 

 A few fourth-stage nymphs were also present on this date. 

 Although the younger nymphs were more commonly seen on 

 the leaves, the older ones rested, for the most part, on the 

 smaller twigs. When the hand was brought near they would 

 run rapidly, keeping always on the opposite side. By July 31 

 most of the nymphs had transformed to adults.
