are frequently straight. The exact thickness (i.e., section) of the 

 tibia varies somewhat, in one male from Blocton, Alabama (reported 

 by Scudder and determined by him as gracilipes, the locality, 

 however, being erroneously given as "Blocton, Florida"), being 

 greater than in any other individual seen. The depth of the general 

 body coloration varies appreciably, but there is generally an approxi- 

 mate uniformity in material from the same locality. As a rule, 

 northern adult material shows a more transverse disposition of the 

 color pattern and southern material a more longitudinal one. The 

 two tendencies are to be seen in many forms of this genus, sometimes 

 both the longitudinal and transverse being developed in the same 

 individual, in others one at the expense of the other and again a 

 general suffusion tones all to a deeper uniformity. The scalariform 

 pattern of the caudal femora is weaker in northern than in southern 

 specimens, as is also generally the case with the infuscation of the 

 distal femoral portions and the presence of the pale pregenicular 

 annulus on the caudal femora. These two latter features are rarely 

 indicated in northern adults, but distinct in all the southern specimens. 

 Immature specimens from all localities, however, have a decidedly 

 contrasted color pattern, made up of longitudinal and transverse 

 elements, much as in the southern States adults, with darkened 

 femoral apices and distinct pale pregenicular annuli on the caudal 

 femora.

We have also a pair of specimens labelled "North Carolina, 

 (Morrison)," determined and recorded as this species by Scudder. 

 At the present time it is not possible to determine the correctness 

 of Scudder's assignment of Burmeister's name to this species, the 

 description of which is quite inadequate to place positively the 

 name, but it seems quite probable that his action was correct. In 

 addition to this North Carolina material, we have before us quite a 

 few specimens from the northeastern States. Through the kindness 

 of Dr. E. M. Walker, we have been able to examine four male and 

 three female paratypes of that author's C. pallidipes, described from 

 five localities in Ontario. 124 This is the northern extreme of the
