This insect occurs in New Mexico in two varieties, which 

 may possibly prove to be distinct si)ecies. Unfortunately 

 the species is rare, and only a few specimens have been 

 collected. As the New Mexico varieties do not precisely 

 agree with the typical form from Texas, they are herewith 

 described : — 



\i\x. fallugiiv. 



Pubescent markings bright orange-fulvous (pale ochraceous 

 or tawny in the type) ; mcsothorax extremely densely punc- 

 tured, so as to be dull ; the most distal point of third sub- 

 marginal cell not much above its middle.

Var. rociadensis. 



Pubescent markings pale ochraceous, those on abdomen 

 white shaded with ochraceous; disk of mesothorax with the 

 punctures well separated, showing the shining surface 

 between ; the most distal point of third submarginal cell con- 

 spicuously above its middle. Looks like a large .1/. mirandiij 

 but easily distinguished by the dark wings and teguhc and 

 the shape of the abdominal markings.
