It may be noted that cage i would doubtless have shown 

 more of certain kinds if the soil had been thoroughly sifted and 

 also that the small number of the commoner Jassids may be 

 attributed to the presence of the spiders and phalangids which 

 had evidently been making a good living inside the cage. The 

 most noteworthy point probably is the enormous number of 

 Acocephalus albifrons which were around the crowns of the 

 grass and even down under the litter and in some cases under 

 loose earth, leading an almost subterranean life. 



A cage in another field included capsids, Leptoterna dolo- 

 brata, Philaenus spumarins, Draeculacephala mollipes, Cicadula 

 6-notata, Acocephalus striatus, Deltocephalus minki and sayi, 

 Agallia 4-punctata and a species of Dicraneura aside from 

 other forms not of special importance in this connection. 



The Six-spotted Leafhopper. 



(Cicadula sexnotata Fallen.) 



This species presents some very interesting questions and, 

 in connection with its very evident ability to cause serious 

 injuries to various crops, merits a careful study. 



It is a very widely distributed species occurring in Europe 

 and North America in the latter being known from Alaska to 

 Florida and a number of records of its destructive habits have 

 been given but it has received rather scant attention on the 

 nart of economic entomologists. While the insect may be 

 found in numbers the attacks made by the larval stages are 

 often so obscure that they may be overlooked or attributed LO 

 other causes.
