Observations in the field clearly point to the fact that L. 

 circumcincta. Tapper, is the § of £. circumducta, Wlk. Mr. 

 Tepper certainly describes c? and $ of L. circtimcincta, the 

 former of which only, he says, has lobiform elytra, the latter 

 being wholly wingless ; but I am informed by the South Aus- 

 tralian Museum that the $ type of L. circumcincta, Tepp., has 

 the elytra torn off, a fragment being left on one side. Probably 

 Mr. Tepper overlooked this. My field observations are : — 

 From 22nd to 27th March, 1914, I took a cockroach in great 

 abundance near Healesville, under the bark of Eucalyptus 

 viminalis ; S and $ closely associated, and no other cockroach 

 in their company. I also took some o on the wing at night. 

 All the ,S were E. circumducta, Wlk., all the $ L. circumcincta, 

 Tepp., and no ? was taken with the ootheca attached. On nth 

 April following, Mr. Reginald Kelly and I, collecting from the 

 same trees, found but one 3, whilst the 9 were very abundant, 

 many of them carrying oothecas partly extruded. 



POLYZOSTERIA MAGNA, Sp. nOV. 



Above dull piceous, smooth, with a faint shagreening towards 

 the margins. Stigmata well marked ; below rufo-stramineous ; 

 ocelliform spots present. Antenna; ochreous. Thoracic 

 tergites above with margins not reflected ; beneath rufo- 

 stramineous, deepening in colour towards the margins, and 

 furnished with numerous small fuscous macula. Legs rufo- 

 fuscous. Spines of the tibiae bi-seriately arranged. Supra- 

 anal lamina — (^ quadrate, slightly emarginate, posterior third 

 brownish ; ? compressed, deeply emarginate. Cerci short, 

 flattened, blunt at the apex, ochreous with brownish margins. 

 Su]:)genital lamina — ,S sub-quadrate, styles lateral, incurved, 

 brownish, tipped with ochreous ; ? valves rufo-stramineous. 

 In both sexes the supra-anal lamina is considerably shorter 

 than the sub-genital. 



Length. — S, 46 mm. : ?, 46 mm. 



Types. — ^ and ?, National Museum, Melbourne. 



Habitat. — Ouyen, Mallee district, Victoria, Australia. 



It seems best to leave this fine species temporarily in the 

 genus Polyzosteria, although it presents several marked 

 differences from it, and it may be necessary to erect a new 

 genus for its reception. 



EUZOSTERIA METALLICA, Sp. noV. 



Purplish-bronze above, shot with green. Greenish-bronze 

 below. Head greenish-bronze. AntenucTe greenish-piceous. 

 Margins of thoracic and abdominal tergites incrassated, the 

 former scarcely reflexed. Coxae not margined with ochreous. 

 Extreme tips of the femora above and below ochreous. 

 Stigmata very distinct. Supra-anal lamina — J quadrate ;
