riie siujjle speeimi'ii from (Iraiid Junction is of an exceptionally 

 small size, a fcnuile only 17 mm. lonjr. 



This is the larjicst species of the jienus and is not nnconiinoii at the 

 caslcin base of the IJocrky Mountains in Coloratlo. 1 l»a\ e considered 

 it probable that this is the species described ]»y Dodjje under the name 

 C((loj)t€)iux rcf/dUs, but the description does not very well apply to it. 

 I am jiuidetl partly by a sketch of the niarkinj^s of the te<,nnina sent 

 iiic many years ajjfo by Mr. l)odj»e. and partly by the impossibility of 

 ajtplyinyf the des<*ription to any other known species.

 zona, wantinji" on the pro/ona. the latter with a pair (»f api)roximate, 

 anteriorly conver^iny', dull olivaceo fuscous, rather obscure, narrow

 and an oblique ridge on each side, as in .4^. rf//<///.s-, but much less 

 lirominent; furcula indicated merely by a pair of thickenings of the 

 inner angles of the mesially parted terminal dorsal segment; cerci as 

 in Ac. reffidiSy but with the apn-al jxtrtion less slender and straighter; 

 infracercal plate just shorter than the sui)raanal. concealed by the 

 recumbent cerci; subapical tubercle of subgenital plate feebly promi- 

 nent, very blunt and rouuded.
