Cephalocoema calamus Burmeister?

We refer the present specimen to this poorly understood species 

 with a query. The fastigium is faintly tapering with the apex little 

 blunted, which feature is not in accord with the original description, 

 but this seems of minor importance, as there is some individual 

 variation in this respect in the group. The size is appreciably less 

 than that originally given for the sex (3f inches), but in this our 

 specimen is very close to the male from Brazil measured by Brunner 

 ^nd tentatively referred by him to calamus}^ 



The original localities for this species were Villa Occidental, Gran 

 Chaco and the Rio Apa.
