Marurii (April) ; Santarem. Two specimens. 



This species belongs, no doubt, close to G. violaceus Hdl., described 

 from a single defective specimen from Brazil, which, with other 

 parts, lacked the abdomen. The present species is clearly more 

 allied to the bipunetatus group than to chilensis, and it is probable 

 that it and violaceus form a group. In coloration this new species 

 seems quite distinct from its allies ; it would be interesting to know 

 whether the abdomen of violaceus is similarly colored.
