 northern California, from the old Uhler collection, 

 and a female from Oregon, no locality given. These 

 Fig. 94.— steiroxys are kScudder's types. In the collection of the Museum 

 of Comparative Zoology at Cambridge, Massachusetts, 

 are a number of female specimens from Oregon in 

 which the ovipositors are almost straight. The National Museum 

 contains several specimens, all females, which are referred here. 

 They are from Pullman, Washington, July and August; Jackson's 

 Hole, Wyoming, August; Fort McLeod, British America, August 

 and one without label. These specimens are referred here by locality 

 rather than by any noticeable differences separating them from dark 

 forms of trillneata.
