Obs. Stephens (Tab. Ichneumonide, vol. vii. p. 126.) indicates a genus next 
to Ophion, which he names Enicospilus, differing from Ophion in having 
the first submarginal cell spotted. His pl. 40. fig. 4. is evidently intended 
for aspecies of this genius, of which the species are not yet indicated.
