Simon, Ann. Soc. Ent. Belg. xlii. 1898, p. 20. Type $ , in coll. Mus. Imper. Berlin. Ilab. Colombia. Although the identity of this species cannot be satisfactorily settled without reference to the type-specimen, if it still exists, J give a description and figures of the characters of a form with annulated legs which was taken in Colombia. If the type no longer exists, and no more exact locality than " Colombia " can be ascertained for the type-specimen, then the examples here described stand as " topotypes "-examples from the same locality in which the type was taken-and will serve as a standard of comparison for the species in the place of the original type. Had Simon given more definite characters (for the majority of the species of Trechalea possess 3 teeth) which would enable us to recognize his identification of T. longitarsis with any certainty, and if these (for he makes no mention of the locality) were taken in Colombia, then his examples would be the recognized " topo-types " to which we should have to refer for an identification of T. longitarsis (C. L. Koch). Present identification of T. longitarsis (sec. F. P.-Cambr.). Total length, <$ 20, $ 25 mm.- $ • Leg i. 61 ; ii. 68 ; iii. 55 ; iv. 75 mm. Tib. i. 15 ; iv. 16*5 mm. Prot. iv. 21 mm.

Carapace rich brown-black, with a pale orange A-shaped spot behind the eyes, having a central dusky line, and one on each side ; a pale rufous-white, narrow, submarginal band, and a narrow black velvety marginal band. Abdomen brown, with a black central foliated band: a more exact description is impossible from dried and wrinkled examples. Sternum and ventral area dull yellow-brown. Legs brown, very distinctly annulated with rufous-white hairs, protarsi less distinctly, tarsi |
