2210 Insects. 



investigation of other orders, then I doubt not many unexpected novel- 

 ties will be met with, and probably all the species which I have 

 placed in this Appendix may — without doubt of their being indige- 

 nous — be arranged amongst our British bees. 



Halictus sexcinctus, Lair. Gener. Crust, et Ins., Walckenaer, 



St. Fargeau. 

 Andrena rufipes, Spinola. Hylaus sexcinctus, Fab., male. Hylceus 

 arbustorum, Panz., male. Not Melitta quadricincta, Kirby, male, 

 (Walckenaer). 



Female. — (Length 6 — 8 lines). Black ; the face clothed with pale 

 fulvous pubescence ; the clypeus naked and roughly punctured ; the 

 antenna? nigro-piceous beneath. Thorax thinly clothed above with 

 pale fulvous pubescence, most sparing on the disk ; the tegulae testa- 

 ceous ; the wings slightly fuscous, and slightly clouded at their apical 

 margins ; the legs have a fulvous pubescence ; the calcaria and apical 

 joints of the tarsi testaceous. Abdomen, the first segment has a little 

 pale fulvous pubescence at the base ; all the segments have a conti- 

 nuous pale fulvous marginal fascia, between which the abdomen has 

 a short brown-black pubescence. 



Male. — (Length 4| — 6 lines). Black ; the face clothed with short 

 pale fulvous pubescence ; the apical margin of the clypeus luteous ; 

 the apex of the mandibles ferruginous; the antennae luteous beneath ; 

 the scape yellow beneath ; the terminal joints are recurved or convo- 

 lute. Thorax clothed as in the female ; the tegulae luteous ; the wings 

 hyaline, slightly clouded at their apical margins ; the legs pale luteous ; 

 the coxae and trochanters brown-black. Abdomen cylindrical, elon- 

 gate, not wider than the thorax ; the segments have each a continuous 

 pale fulvous marginal fascia ; beneath, the margins of the segments 

 are testaceous. 



Specimens of this species are placed in the national collection of 

 British insects, probably by Dr. Leach ; but as the locality from 

 whence they came cannot be found, I think there is reason to doubt 

 their being indigenous, and to suppose that they were placed in the 

 cabinet by some mistake. I shall be glad to be convinced to the con- 

 trary by the capture of so fine a species. There is a specimen of the 

 male in the collection of Mr. Desvignes.
