This species has not previously been recorded from Cali- 
fornia. California specimens are larger than more eastern 
specimens, with longer antennae. Oklahoma specimens have 
the third abdominal tergite 1.5 times the length of the 
pterothorax, while in the California males this ratio was 1.7 
and 1.9. The difference in color is striking, the Southern 
California specimens being much darker. Material from 
Riverside shows a gradation in size down to that of typical 
texanus, and a $ from Olanche, California (MCZ), is inter- 
mediate in its coloration between the paler texanus and the 
darker southern specimens. Some means of measurements 
of the California specimens follow (in mm.) :
