Platypedia putnami var. occidentalis new variety. 



Type male and allotype female, Carrville, Trinity Co., California, June 

 21, 1913 (Dr. E. C. Van Dyke). Collection California Academy of Sciences. 



This variety has the head and thorax blue-black, marked with brilliant 

 orange as in typical putnaiiii, but it is generally larger and has lighter colored 

 legs. The front femora are not shining black with extremities pale as is the 

 case with Nebraska, Colorado, Montana and New Mexico specimens of 

 putnami, but with the exception of being slightly darkened beneath, the femora 

 are entirely light chestnut colored or reddish orange. The fore wings have 

 slightly yellowish reflections; costal margin is brilliant orange to the end of 

 the radial cell, the remaining veins are black or nearly so, and the membranes 

 at base are brilliant orange.

 Davis collection. 



This variety is blue-black but not so much so as in typical putnami, and has 

 the lighter markings orange-yellow instead of the brilliant orange or blood-red 

 of typical putnami. The fore femora are entirely black except the extremities, 

 as in putnami. In Colorado and western Nebraska the colors of putnami are 

 remarkable for their brilliancy, the membranes at the base of the fore wings 

 are often of a blood-red, while further west true putnami is replaced in cer- 

 tain areas as in Utah by the present variety with orange-yellow markings, 

 which contrast strongly with the somewhat dull blue-black of the greater part 

 of the body.
