the distal patches are confluent on the fourth; in three they are conflu- 

 ent on the third; and in two, on the third and fifth primary. The 

 same irregularity is shown in all specimens representing other races, 

 with the exception of cauca, fully 96 per cent, having the distal patches 

 joined on at least one primary and the majority on two or more. In 

 cauc&, however, none of the specimens examined have any of these 

 markings confluent, but in view of the variability of the character in 

 other forms it would seem probable that in ca-ucae also in a larger series 

 it would be found to be inconstant.
