Piez._ 411. 66. _Latreille Hist. Nat. Fourm._ 127. _Oliv. Enc. Méth. Ins._ 6. 499. HABITAT: Island of Johanna, near Madagascar. Antennæ longer than the thorax, the first joint almost equal to the remainder. Eyes small, and placed very backward. Head black and small, armed with very strong and sharp jaws. Thorax brown, having on the fore part two spines, one on each side bending outwardly; on the top are likewise two more, bending towards the abdomen.

ORDER: Hymenoptera. SECTION: Diploptera. FAMILY: Vespidæ, _Leach_. GENUS. VESPA, _Linn. &c._ VESPA ORIENTALIS. Ferruginea, abdomine fasciâ flavâ ante apicem utrinque bipunctatâ. (Long. Corp. 1 unc. 3 lin.) SYN. Vespa orientalis, _Linn. Mant._ 540. _Fabr. Syst. Piez._ 254. 4. Vespa turcica, _Drury, App. vol._ 3. HABITAT: Smyrna (_Drury_). "In Oriente" (_Linn._). Front of the head yellow. Eyes brown. Antennæ 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. Pl. 44. Fig. 6." The correctness of this statement may however be questioned as regards both of the insects in question, which, from their evident relationship to the common English hornet (Vespa Crabro Linn.) must surely possess similar habits to those of that insect. {83}SCOLIA 4-MACULATA.
