 Genus. Vespa, Linn. SjC. 



Vespa Orientalis. Ferruginea, abdomine fascia flava ante apicem utrinque bipunctata. (Long. Corp.

 Vespa turcica, Drury, Ajjp. vol. 3. 



Habitat : Smj'rna (Drury). " In Oriente" (Linn.). 



Front of the head yellow. Eyes brown. Antennae the length of the thorax. Ocelli distinct. Jaws 

 black. Tongue not to be discovered. Thorax and abdomen brown chesnut ; the third and fourth rings 

 of the latter yellow. Wings thin, but not transparent. Legs brown ; the anterior with a single and the 

 four posterior with two tibial spurs. 



Drury observes of this and the next insect, that " they make nests like the mason- 

 fly described in Vol. I. PI. 44. Fig. G." The correctness of this statement may however 

 be questioned as regards both of the insects in question, which, from their evident relation- 

 ship to the common English hornet (Vespa Crabro Linn.) must surely possess similar 

 habits to those of that insect.
