Petiole two-thirds the length of the nodose portion of the first abdo- 

 minal segment; the nodose portion above and anterior part of second 

 tergdte ' ' spatter-punctured ' ' much less strongly so on the latter. 



Taken in King's Canon, Ormshy county, Nevada. Also related to alhi- 

 pes and nubeculus. From the latter it differs in lacking the ventral tufts 

 and in other characters. From the former it differs in not having the 

 ' ' first and second transverse cubital veins uniting above ' ', a character 

 used by Fox in his synopsis. The various descriptions of albipes which 

 have been given are wholly insufficient as diagnoses in this genus. Ho- 

 wever, regardless of what the nan^e albipes may possibly apply to, the 

 form described above will be easy to recognize by the characters I have 

 mentioned.
