Mar., .909] Wheeler: Ants from Victoria, Australia. 25 



The description of this species has been sent to the "Canadian 

 Entomologist." The only specimen I have is a male without a head. 

 It may be briefly characterized as follows : Black, opaque ; tegul^e, 

 extreme angles of pronotum, legs orange-color or almost that dark. 

 Venation normal, pale brown ; stigma a little paler at base, obliquely 

 truncate at apex with the lower margin rounded. Procidentia narrow, 

 truncate at apex ; hypopygium obtuse at apex. 



Habitat. — Delta and Ft. Collins, Colo. Type in the collection 

 of the Colorado Agricultural College. 



A very distinct species easily separated by the foregoing table.

 unknown sexual forms, was made in a new locality, and is accompanied 

 by some interesting notes, it is well worth recording.
