 male, 11 nun., female 11.5 mm. 



One male, 4 females. Venis Mecas, San Luis Potosi, Alexico, June <I. 

 E. Palmer; Mt. Alvarez, San Luis Potosi, Mexico, K. Palmer; Sierra 

 Xola, Tamaulipas, Mexico, December 3-0, E. Palmer. 



It is possible that the nmle, which comes from Venis Mecas, may be
