 the Rocky Mountains, southward only at higher elevations, becoming subalpine in 

 New Mexico. 



Not contained in any of the Mexican collections. 



This insect is common on low, wet meadows over a much more extended region 

 than is generally supposed. Possibly the other recognized American species inhabit 

 similar localities.]

The known representatives of this genus are, for the most part, confined to the 

 Oriental regions, particularly northward, and in the mountain districts of Middle and 

 Southern Europe. In America there are three or four recognized species which are 

 still referred to it. Two of these have been taken in places not very remote from the 

 northern boundary of Mexico. The collections before me contain a single specimen 

 of an undescribed species coming from Cuernavaca, in the State of Morelos, Mexico. 

 Undoubtedly, the mountain-regions bordering the plateaux of the intervening country 

 will disclose others when carefully investigated. This new form, together with the 

 two known North-American species already referred to, may be distinguished by 

 the subjoined analytical Table : —

A. Fastigium of the vertex decidedly angulate and provided with profound 



lateral foveolae. Posterior femora slender. 



b\ Antennae, even of the ? (those of the J always relatively much 



longer), equal in length to the head and thorax combined. 



Fastigium of the vertex in the <? somewhat acute. [Plains.] 



c\ Larger (length 17-19 millim.). The anterior tibiae of $ not

expanding apically, and somewhat sulcate externally .... [2. clavatus, Thorn.]
