lack sufficient material to enable us to test out satisfactorily the 

 geographic value of characters suggested by our series. 



We have before us the typical material on which Bruner's occi- 

 dentalis, the basis of blatchleyi, was founded and have examined all 

 the types of both walshii and amplectens, hence the above synonymy 

 has been established by reference to the basic material. 



That Scudder was in great difficulty with this variable species is 

 evidenced by his treatment of the synonymic names. The first , 

 walshii, he placed in his rusticus series, the second, amplectens, in 

 his fasciatus series and the third, blatchleyi, in his texanus series. 

 In our opinion the species clearly belongs to the Fasciatus Group; 

 that is, it should be placed in the general vicinity of fasciatus, for 

 while the genitalia are different in some respects, a number of other 

 features are very similar. 



The extremes in size in the present series are as follows:

The Currahee Mountain and Sharp Mountain series show con- 

 siderable individual variation in size, the minimum of the female 

 sex from Currahee Mountain being hardly larger than the minimum 

 measured above, while the Sharp Mountain lot shows even greater 

 variation in the male than is found in the same sex in the Currahee 

 Mountain representation. There is very little variation in color, 

 the most apparent being the degree of infuscation of the anal area of 

 the tegmina, the presence or absence of the pale spot proximo-dorsad 

 on the external pagina of the caudal femora and the absence or 

 presence, depth and extent of a dark pregenicular annulus on the 

 caudal tibiae. 



All of the specimens taken by us were secured in the normal 

 sylvan habitat of the species; on Currahee Mountain on the 

 upper slopes of the mountain, among the heavy undergrowth of 

 vines, oak sprouts and grasses in a forest composed chiefly of black- 

 jack oak, being only occasional on the slopes and fairly abundant 

 on the summit; on Sharp Mountain under similar conditions in 

 a forest of coniferous and deciduous trees and all seen were taken, 

 while at Dalton one was secured on a steep slope under deciduous 

 trees.
