This species so closely resembles Ampulex compressus that perhaps it 

 will be regarded by some persons as only a local variety ; I have 

 sepai'ated it for the following reasons : in the first place, the head is 

 rounded behind, whereas in A. compressus it is transverse with the 

 angles obtuse, and the eyes are more closely approximate than in that 

 species ; the second lateral carina on the metathorax is simple, while 

 in A, compressus it becomes double towards the apex : all the speci- 

 mens from Makassar are brilliant purple in both sexes.
