From the careful description of c.xcisa Brauer (synony- 

 mous with luteifcnnis according to Hagen), these three 

 males differ as follows : labium bluish instead of yel- 

 lowish; suture between the eyes much more than double 

 as long as the occiput, being nearly as long as the com- 

 bined length of frons and vertex, measured along the 

 mid-dorsal longitudinal line; first femora blue inferiorly: 

 mid-dorsal, longitudinal, abdominal stripe blue instead of 

 yellow; 9 with a mid-dorsal, apical, triangular, blue spot, 

 a similar smaller one on 10 in the males from Mesa Verde 

 and Miraflores; superior appendages a little longer than 

 9+10; costa with a yellowish line to the nodus.
