Although the identity of this species cannot be satisfactorily 
settled without reference to the type-specimen, if it still exists, 
T 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 “ ¢opotypes” —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 7’rechalea possess 3 teeth) which would enable us to 
recognize his identification of 7’. 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. Li. Koch).

brown, with a black central foliated band: a more exact description 
is impossible from dried and wrinkled examples. Sternum and
