T haumasia velox Simon. (Plate X IV . fig. 1.) Loc. cit. Type S , in coll. E. Simon. Total length 8 mm. Thaumasia velox F. P.-Cambr. Biol. Centr.-Amer., Arach. Aran, ii. p. 309, t. 30. figs. 5, 5 a-c (<5). The type of this species ( ) was taken on the Amazons, and, short of first-hand evidence, 1 do not doubt that the male and female, taken by myself amongst the foliage on the margin of a small " furo" in the Parana Buy ass u, near Breves, Lower Amazons, must be referred to this species. The male identified as belonging to this species from Guatemala 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. Hob. L ower A mazons : Santarem; Breves, Parana Buyassu (E. P.-C., 1895-96); Rio Tocantins, S. Paulo de Oliven^a (de Mathan); Guatemala (Sarg). 7. T haumasia annulipes, sp. nov., $ .
