scales on the vertex and the gray white labial palpi will separate 

 snellenella from basilica and liguritrix, respectively. 



In Madera Canyon snellenella appears to be a spring species inas- 

 much as no specimens were taken during the 1959 season from June 

 29-November 11. On the other hand the specimen from the Huachuca 

 Mts. (less than 50 miles distant) was collected in September; thus, 

 the species may emerge sporadically during the year.
