In this paper I have described and enumerated all the Hymenoptera collected by 
Mr. Gardiner in the Seychelles, except the Ants. Up till now our information 
regarding the species inhabiting this group we owe to two papers by MM. Emery & 
Pérez, published in the Annales de la Soc. Ent. de France in 1894, based on the 
collections made by Mr. Ch. Alluaud. Mr. Gardiner has added considerably to our 
knowledge of the Hymenoptera of the islands alike in the Aculeate and the Terebrant 
sections of the Order. Of the known species Apis wnicolor is a Madagascar form; 
Aylocopa caffra and Sceliphron hemipterum are African; while Wegachile disjuncta, 
I. mystacea, Polistes hebreus, Sphex uwmbrosus, Sceliphron bengalense, Ampulex 
compressa, and Ophion rufus are common Oriental species but found also in Africa; Hvania 
appendigaster is cosmopolitan. The Ichneumon genus Hehthromorpha is noteworthy 
for its wide distribution in oceanic islands. Braunsia and Campocentrus are genera 
not uncommon in Africa. 
As regards the habits of the species found in the Islands it is suggestive that so many 
of them belong to genera of which many, if not most, of the species prey on Orthoptera. 
Thus Hvania appendigaster lives in the egg-cases of the Cockroach. Réaumur long 
ago stated that Ampulex collected Blattz for its nests as food for the larve; a fact 
confirmed by later observers. Sphexr umbrosus has been observed to prey on Crickets, 
which are also used by the Larridz (Notogonia &c.) as food for their young. 
My. Gardiner, it may be added, collected from October to December in the Seychelles.

One example has the basal two segments of the abdomen rufo-testaceous. The drone 
has the abdomen rufo-testaceous, with the segments more or less black at the base; the 
sentellum and metanotum are dark testaceous. The hair on the head and thorax is 
- rufo-testaceous.
