ferent and the size much smaller. It resembles loripes 

 Casey, but differs from it in having the whole of the discal 

 area of the prothorax, excepting the sulcate lateral border, 

 punctate and hairy. The elytral striae also differ from his 

 description, as does the margined portion of the prosternum 

 and the vestiture of the pygidium. Casey did not describe 

 the vestiture of the leg surface. 



Notes on the Life-History of the Salt Marsh 

 Cicada (Tibicen viridifascia Walker) (Hemip.)

 College and Experiment Station. 



(Plate III) 



While collecting at Wrightsville Beach, North Carolina, 

 on July 27, 1919, we had the fortune to collect a goodly num- 

 ber of the adults of the Salt Marsh Cicada {Tibicen viridi- 

 fascia Walk.). We also made some observations on the 

 life-history of this species which seem worth recording. 



The adults were common on the beach, frequenting the 

 tall dense grasses that abound everywhere in that region. 

 They were especially common on the so-called Sea Oats 

 {Uniola paniculata) which grows luxuriantly on the higher 

 sand dunes on the WVightsville Banks. The males were 

 busily singing and usually half a dozen or more could be heard 

 at one time. The song is a high pitched zing-g-g-g which 

 is much prolonged. One male observed singing was clinging 

 to a stem of the sea oats about five feet from the ground, 

 head up and abdomen well elevated. Several other males 

 were flushed from a coarse, densely matted, short grass which 

 grows near the edge of the water at low tide. These were 

 not singing and were only flushed when they were in danger 

 of being tramped upon. All the females collected were found 

 in this latter locality but a numbr of adults were flushed from 

 the sea oats which did not give the peculiar startled zing 

 given by the disturbed males and were apparently females.
