single female from Bayville, Va., August 19, 1908, has also been 

 examined. Of these specimens but one male is macropterous (Mt. 

 Pisgah) and but one female (Mt. Pisgah) has tegmina almost as long 

 as the body. 



The Pisgah and Sulphur Springs lots each contain a single specimen 

 having the ovipositor slightly shorter than the caudal femur, but as 

 this is the exception and not the rule, we have considered the material 

 from those localities to be N. fasciatus, while in our Raleigh series 

 but one in seven has the ovipositor longer than the caudal femur, so 

 we have placed the latter locality's representatives under N. fasciatus 

 socius. The specimens tabulated above show the following differences 

 in the proportion of these two parts: 



Ovipositor longer ( + ) or shorter (—) than caudal femur.

The Sulphur Springs specimens are paler, more rufous and with 

 more decided pattern than the other and more usual specimens. These 

 may represent N. canus Scudder, but the structural characters given 

 for that form do not hold in the present specimens, so it seems more 

 desirable to consider them slightly aberrant fasciatus. A number of 

 such pale colored individuals from Massachusetts, New Jersey and 

 .Maryland have been examined by us. 



Typical Nemobius fasciatus appears to be replaced in the entire 

 Power Austral zone of the southeastern States by A r . fasciatus socius
