seems quite certain. In his original description of popeana Scudder 

 states that some specimens, at least in the female and on one side, has 

 one or two spines on the inner carina of the anterior tibia above. This 

 statement was made by reason of an erroneous observation on the 

 part of the describer— that of mistaking- the middle leg- of the right 

 side of one of the specimens for the anterior one. These two legs 

 were twisted across each other at the base in such a manner as to re- 

 quire especial care to notice the displacement. 



The males of scudderl \Qvy mucli resemble those of IdJoHtatus 

 sinuata. The types were taken in an outhouse at Mesilla Park, New 

 Mexico, and, as stated by Cockerell, are prol)ably nocturnal. One 

 specimen was found killed by a centipede, S<-()!;)j><)i<[i'a herois.
