Female. — Fulvo-ferruginous, smooth and polished ; head broad, flat- 

 tened ; clypeus tinged with yellowish, tips of mandibles and of anten- 

 ncB, black ; cheeks with a few scattering pale hairs ; thorax subopaque, 

 finely aciculate, transversely so above, obliquely so on pleura and sides

that my consors (I. c, p. 449) would prove to be the % of regina, which suppo- 

 sition was strengthened by the capture of both the last named species in New 

 Mexico by Dr. Lewis. Dr. de Saussure may, however, be correct, and my con- 

 sors may be a distinct species. In this case the name of the latter species must 

 be changed to that of zonaria, the former name being used by Dr. de Saussure 

 in the paper above quoted. 



Scolia Ridingsii, Cress., from Colorado, seems to agree very well with Dr. de 

 Baussurc's descrii)tion of what ho decides to be a variety of nobilitata Fabr. (1. 

 c, p. IS), but which, I think, is a distinct, though closely allied, species.
