A single specimen of this remarkable insect was taken at Cape Gregory, 
Straits of Magellan, which I have the pleasure of dedicating to Captain 
P. P. King. EU | 
As this insect partakes of the characters of both Pompilus and Planiceps, I 
have not ventured to refer it to either. It seems more nearly allied to the 
former, from which the raptorious fore legs would be scarcely sufficient to 
distinguish it without the peculiar head. "The trophi are unluckily lost; but 
there are great variations of them within the limits of the genus Pompilus as at 
present constituted. 
*43. SCOLIA QUADRIMACULATA. Fabr. 
The male, which seems to have been unknown to Fabricius, has a yellow 
spot on the basal joint of the abdomen, which has a chalybeous tint ; and the 
2nd, 3rd, and sometimes the 4th segment are margined with yellow, uniting 
the lateral spots, which are smaller and paler than those of the female.
