Nothing is known about the biology of this species, for while it has 

 a wide range it appears to be very uncommon. During the coiu-se of 

 his work Wallis (1Q28, p. 173) saw only 10 specimens and I have seen 

 only 19, many of them the same specimens seen by Wallis. 



The species is apparently a summer form, having been collected 

 from JXme to August, Because of the rarity of the species, complete 

 data on the labels and the location of collections housing the specimens 

 are given below.
