About thirty specimens, all males, were taken in an open glade 

 in the forest, by sprinkling the foliage with a citronella oil 

 mixture; until the oil was used, no specimens were seen. One 

 female specimen was taken with a sweeping net, on the edge of 

 the forest; it differs from the male in having darker-coloured 

 legs, and in the whole of the abdomen, witli the exception of th& 

 basal reddish band, being black.
