u. p. 309, t. 30. figs. 5, 5 a-c (¢). 
The type of this species (¢) was taken on the Amazons, and, 
short of first-hand evidence, I do not doubt that the male and 
female, taken by myself amongst the foliage on the margin of a 
small “‘ furo” in the Parana Buyassu, near Breves, Lower Amazons, 
must be referred to this species. 
The male identified as belonging to this species from Guate- 
mala may possibly be not identical, but it is impossible to be 
certain with but one example from each locality. 
The female has not been before described, but a figure of the 
vulva is given on the Plate. For figures of the male see Biol. 
Centr.-Amer. loc. cit. above.
