'^^''•'l Shaw, Anstralian Blattidce. loi; 



9 compressed in the middle, not emarginate. Cerci broad, 

 flattened, acuminate, of a rich peacock-green above and on 

 the outer margins ; below brownish ; extreme apices tipped 

 with ochreous, considerably longer than the lamina in S-, hut 

 of the same length in ?. Sub-genital lamina — ;^, sub-quadrate 

 posterior margin rounded, styles lateral, long, and incurved ; 

 $, sub-genital valves concolorous. Tibial spines rufous tipped 

 with castaneous, bi-seriately arranged. Tibiae on the inner 

 aspect furnished with a thick fringe of rufo-testaceous hairs. 



Length. — c^, 22.5 mm. ; $, 23 mm. 



Types. — (5 and ?, National Museum, Melbourne. 



Habitat. — Mount Erica, Baw Baw, Victoria, Austraha (Mr. 

 E. O. Armytage). 



Platyzosteria pullata, sp. nov. 



Allied to P. analis, Sauss., but differing in the abdomen being 

 convex, not depressed, and being narrower in proportion to 

 the thorax than in that species. In P. analis, Sauss., the fourth 

 abdominal tergite is the broadest portion of the insect, and is 

 broader than the metanotum, whilst in this species this 

 relation is reversed. The yellow margins of the coxae are 

 narrower than in P. analis, Sauss. The sub-genital lamina 

 is much more deeply emarginate. 



Length. — (J, 27 mm.

Habitat. — Mount Baw Baw, Victoria, Australia. 



Platyzosteria brigit.e, sp. nov. 



Piceous, nitid. Thoracic tergites with some impressed dots, 

 somewhat scabrous laterally, most marked at the posterior 

 angles of the metanotum. Rudiments of the elytra separated 

 from the mesonotum for rather more than one-third of their 

 length on the inner side, sub-acuminate. Antennae brown, 

 except the basal joints, which are piceous. Abdominal tergites 

 I to 5 scabrous laterally ; 6 and 7 with the posterior two-thirds 

 scabrous. Lateral margins of the 7th abdominal tergite serrate. 

 Supra-anal lamina, o and ?, emarginate and denticulate. 

 Cerci longer than the lamina in o, of about the same length in$ ; 

 tipped with rufo-fuscous. Legs piceous, extreme margins of 

 the posterior coxae edged with rufo-fuscous. Tarsi with the 

 distal joint and ungues rufo-fuscous. 



Length. — <S, 16 mm. ; ?, 19 mm. 



Types. — S and 9 in my collection. 



Habitat. — Victoria, Australia. 



This species I found very abundant in the Healesville 

 district. It varies considerably in size, many adult examples 

 being smaller than the types, and a few larger. It is near to 

 P. biglmnis, Sauss., but is consistently piceous, without yellow
