Ress. a. cliff. — This species is rendered very distinct by its less 

 depressed form, and its quite sessile abdomen, which gives it the 

 appearance of a Vespa. The first segment is so short, that the 

 superior face is almost wanting ; its anterior face presents as in 

 Vespa a sort of obsolete notch at its summit, which is an impres 

 sion of the post-scutel. The anterior face has not the triangular 

 form, its superior margin being arcuate as in the Vespa.
