.called by this name. I find the foreign species to 

 be extremely numerous, some of them are the most 

 splendid insects in the class. My observation, in 

 my paper upon this genus (c/), that colour seems 

 constant, I find upon a view of the exotic speci- 

 mens, is not founded in fact, although a consider- 

 able proportion are distinguished by the same co- 

 lours. The antennae of all are revolute, a circum- 

 stance not noticed in that paper. 



TIPHIA. This genus, T.femoratu, at least, and 

 its affinities, is nearly related both to Scolia and 

 Mutilla. Its eyes are oval and remarkably small ; 

 its antennae are anterior, and spiral with a fusiform 

 apex ; its truncus is retuse at both ends, and nearly 

 cubical, and its colium is larger than the thorax. 

 Some of the "Piphice in Sir Joseph Banks's collec- 

 tion, which, if my recollection does not mislead me, 

 were labelled by Fabricius, belong to a separate ge- 

 nus, intermediate between Vespa and Bembex. 

 Their tongue, and wings seem to come near the 

 form^er genus, and their large oval eyes, and conic 

 abdomen, to the latter, but thev have not the conic 

 inflected labium, which is its most striking distinct 

 tion. Christius has figured one of these under the 

 name of Fespa hicJypeata{e). T. coUaris of Fa- 

 bricius has reniform eyes, and is a true Scolia. T. 

 pedestris of the same author, if I do not mistake 

 his insect/ seems rather to belong to Mutilla ; it is
