My single specimen o£ this species is not very perfect ; and 

 I cannot say any thing very positive about it. It is believed 

 to have been obtained at Oyapok, Cayenne, by M. Jelski,

I am at present uncertain whether this species is really sepa- 

 rable from the preceding. My single specimen is darker on the 

 back and rather longer in the leg than that of G. macularia, 

 and has but few indications of the black markings on the 

 breast. In general size there is little difference.
