Problems. The specimens of S. flavidus are variable in structure. 
They sometimes have an elevated eye region or humps on the anterior 
of the abdomen (Levi, 1955). Reexamining larger collections re- 
established my previous observation that the genitalia of Spintharus 
are variable. Evidence is presented in Figures 1 and 2. Of interest 
is the much shorter embolus in the palpus of a North Carolina speci- 
men (F) and in one series from Panama (R). A second series from 
the same Panamanian locality contained three individuals with emboli 
of variable length (Q). The ducts of the female epigynum also seem 
variable in length, but since their study means damaging specimens, 
this was not done. This might be advisable when more specimens 
are on hand.
