The literature furnishes us with but slight information regard- 
ing this interesting little species, which as far as known occurs only 
in northeastern Brazil, the most eastern (Natal) and most west- 
ern (Para) records being given above. The form of the trochanter 
and the position of the dactyls, combined with the rather pro- 
nounced coloration, are distinctive features of the species. The 
present series of adults are equal to or very slightly larger than 
the original measurements, and in the same the wings are invari- 
ably caudate, appreciably surpassing the apex of the abdomen.

The occurrence of this species in northeastern Brazil is, to say 
the least, rather surprising, but comparisons of the present ma- 
terial with the original description, and material of both sexes 
from Argentina (Jujuy, Chacras de Coria and Mendoza), show 
the Brazilian specimens to be inseparalile from the more austral 
individuals. No previous records from localities to the northeast 
of the Alisiones, Argentina and the Rio Apa, Paraguay, were 
known. 
This species is closely related to S. mexicanus (Burmeister) and 
acletus Rehn and Hebard, while tenuis is, in general, more nearly
