This species I found associated with M. tibialis Coq. in the 

 U. S. National Mtuettm collection. It is very similar to that 

 species, but the characters on the legs are at once distinctive. 

 The tibial spur simulates that of armaia, but is not as long and 

 the tarsal notch is more extensive. The second joint of the 

 hind tarsi is noticeably much longer than the preceding one 

 and the fore tibiae also unusually long and slender with the 

 characteristic blade swelling at its middle. I am not aware 

 whether these diaracters exist in tibiaiis Coq. or not.

A specimen before mc from the Yosemitc Valley, Califor- 

 nia, lacks the antennae, but it is evidently this species. 



The spur of the hind tibia, which is no doubt ftmctional in 

 connection with the tarsal notch, is very characteristic of this 

 species. It is not present in any other species known to me, 

 at least as strongly developed as here. Usually such spurs are 

 minute and scarcely noticeable.
