(stretching from these lobes to the l>ase of the scutellum), 

 which are yellow bella, var. ? * 



N. S. Wales. Type in B.M. 



Femora tibiae and tarsi concolorous, testaceous. Middle lobe 

 of mesonotum not .spotted in the middle with yellow, but 

 testaceous at its sides. Ground-colour of thorax and abdo- 

 men black, with a violaceous tinge in certain lights. Pale 

 markings of head and abdomen as in typical bella. 



rubripes, Rohwer. 

 Tasmania. Type in B.M. 



o2 (22) Dorsum of abdomen for the most part yellow or tes- 

 taceous 33. 



- Dorsum of abdomen ehalybeous; at most its sides and ventral 



surface are pale or red . 36. 



33. Antennae blackish. Body except the base of the abdomen 

 almost entirely yellow. Size appears to vary greatly — from 

 15 to 20 mm. long. Details of saw PL XV, Fig. 12. 



aurvlenta, n. sp.f 



* This specimen in the B.M. collection is labelled "bella, var. 

 nigra, Rohw." But I believe that this name is unpublished. It 

 is exceedingly like rubripes, and I doubt if it really differs from the 

 latter specifically. In fact, since all these forms agree absolutely 

 in practically everything but colour, and especially in the highly 

 characteristic structure of their saws, I am tempted to think that 

 Kirby, Westwood, etc., were right in including them all as forms 

 of betid. 



The ,j of bella is probably, as suggested by Konow, foersteri, 

 Westw. But if so, of course Newman's much older name {bella) 

 should be adopted for the species. Konow also sinks the name 

 christii, Westw.. as a synonym of "'foersteri,"' i. e. bella. But this 

 is certainly a mistake, for christii (see above, 19) belongs to the 

 section of Perga in which the 3rd cubital nerve is bent (PL XV. 

 Fig. 14), while in "foersteri." and bella (v) this nerve is straight 

 (PL XV, Fig. 15). 



t Perga (Xyloperga) aurulenta, n. sp. ?. 

 Pallide flava paene tota, sed partibus bis denigratis antennis; 

 suturis abbreviates inter antennas ocellosque posticos, suturis occipi- 

 talibus ct macula prope occipitale foramen sita ; fascia bilobata ante 

 pronoti marginem basalem, vitta lata triangulari in mesonoti lobo 

 medio, aliaque macula (multo minore) ante scutellum ; fascia basali in 

 dorso abdominis; pedum posticorum femoribus, tibiarum apicibus, 

 ct parte tarsorum. Clypei dimidium basale elevatum, ct a dimidio 

 apicali concaviusculo truncatura fere rectilineari transversa separa- 

 tum. Scutellum apicem versus angustatum, lobis eiusdem apica- 

 libus satis longis. Alae flavescentes, venis el stigmate aurantiacis. 

 J ignotus.
