76 MONQGRAPHIA ^GERIARUM ANGLIiE. 



different from that of any other species with which I am 

 acquainted ; yet M. Hubner has not thought proper to separate 

 it from his genus Bembecia, which combined this species with 

 those in the two following genera. 



Sp. 1. Pyrop. Chrysidiforme. Palpi baseos nigri, aptce 

 ochracei nudi : abdomen nigrum cinguUs duabus albidis: 

 alcB squamoscE crocecs, macula lineari hyal'ma.

Palpi baseos hirsuti nigri, apice nudi pallide fulvi : antennae fusco- 

 nigrae, subtus dilutiores basi albae : thorax niger, pectus nigrum 

 immaculatum : abdomen nigrum, cingulis duabus albidis : barba 

 nigra, media parte lutea : femora nigra : tibiae croceae : tarsi 

 flavescentes : alae anticae supra squamosae croceae, linea longi- 

 tudinali medio hyalina, marginibus et macula nigris. 

 Habitat in Mauritania et Italia frequens : in Gallia australi raris- 

 sime. 



I have described this insect, more because I wished to give 

 an example of the genus, than from any conviction of its 

 being a native of this island. It appears to have obtained a 

 place in a cabinet as British ; but it seems scarcely probable 

 that an African insect, although naturalized on the warm shores 

 of the Mediterranean, should have found its way into our colder 

 climate. It was a common and very culpable practice of col- 

 lectors formerly, to fill the spaces left in their cabinets for rare 

 British insects, with some foreign species nearly allied to the 

 British ones that were wanting; a circumstance which sub- 

 tracts greatly from the value of all old specimens, the history 

 of which has not been authentically recorded at the time of 

 capture. This species is closely allied in habit to the fore- 

 going ; it is a heavy dull insect : Laspeyres describes it as 

 " pigrum et sensu fere expers." It also very nearly ap- 

 proaches the genus which follows ; and to the genus Paran- 

 threne several characters pronounce its relationship. 



Genus VI. Bembecia, Hubner. 



Palpi elongati, articulis omnibus squamatis : antennae thorace vix 

 lomjiores, maris ciliatae : abdomen medio crassius, vix barbatum.
