at the sides) in some specimens, but this may be due to im- 

 maturity. I do not believe that this is more than an aberra- 

 tion of the next species (dorsalis). It agrees with it exactly 

 in all structural characters, details of " saws,*' etc. Nor 

 can it be considered as a "subspecies " (— local race) since 

 both forms occur in the same locality, affinis, W. F. Kirby. 



Victoria. Type in B.M. 



■ — Mesopleura at least partly, and abdomen entirely in all specimens 

 seen by me, chalybeous or aeneous (concolorous with the 

 mesonotum, head, etc.) 8. 



8. Large form (about 24 mm. long). The general ground-colour 



in all specimens seen by me is rather green than blue. The 

 details of the "saw" (PI. XIV, Fig. 1) differ from those in 

 all other spp. except affinis. This was the first species of 

 Perga to be described, and is the Type of the genus. 



dorsalis, Leach (? = eucalypti, Scott). 



N. 8. Wales and Victoria. Type (a $) in B.M. 



— Very like dorsalis but smaller (about 20 mm. long) and with a 

 very different saw (PI. XIV, Fig. 7). One specimen in B.M. 

 is coloured like dorsalis, but the others are all rather blue 

 than green intricans, n. n. 



There are three examples of this form in B.M., two from 

 Queensland and one from Adelaide, all £?• At Oxford 

 there is only one, also a $, from Adelaide, which Westwood 

 — wrongly, I believe (v. infra) — considered to be the $ 

 of his schiodtei <$, though it is quite unlike the latter in 

 coloration. It appears therefore necessary to give it a 

 new name. 



Queensland and Adelaide. Type in B.M. 



9. Mesonotum with its side-lobes chalybeous. The middle lobe, 



head, and part of the abdomen testaceous. 



schiodtei, Westw. 



This I believe to be the true $ of schiodtei, Westw. It 

 strongly resembles the <$ in coloration and other char- 

 acters. In B.M. there are, besides the unique $ specimen 

 (S. W. Australia, Swan River), three $$ exactly like 

 Westwood's Type, and all, like the $, from S. W. Australia 

 (one from Swan River). There is no similar $ at Oxford, 

 and Westwood probably was unacquainted with it.
