 confused with 0. sohria, Walker=f/. erythrocnemis, Stal.

 Both sexes were taken on Reevesby Island by burning the low scrub.

 transverse in front, sides retreating; the posterior lobe produced; three longi- 

 tudinal well-developed carinae on pronotum above, the outer ones diverging

Hah. — South Australia: Greenly Island (F. Wood Jones). Type female, 

 I. 14429. 



Three specimens were taken; one was bleached with spirit and a second 

 specimen rather shrivelled. The species is allied to P. palliata, Sjostedt, but 

 differs from that species in its smaller size, broader fastigium, short, thick-set 

 antennae, angular pronotum, and brownish posterior tibiae. 



Peakesia palliata, Sjostedt. (PI. xxxii., fig. 3.) There is before me a 

 single specimen of this species from Ooldea (A. M. Lea) which agrees well with 

 Sjostedt's description and figure. It has the posterior femora pale brown and 

 the tibiae dull green (in the type they were missing). A figure is given for 

 comparison with P. rugosa. 



Phanlacridiimt gemini, Sjostedt. Three females were taken on Pearson and 

 Greenly Islands. They were all of the semi-apterous form and differ somewhat 

 from mainland specimens. 



Family LABIDURIDAE. 



Labidura truncata, Kirby. A male and female of the fully winged form of 

 this species were taken on Pearson Island. 



Anisolabis australis, n. sp. 

 $ . Head smooth, convex, almost circular in outline, but anterior portion 

 produced ; eyes small, projecting a little, viewed from above nearly triangular 

 and longer than wide; antennae short, 14-jointed, the basal joints ovate, becoming 

 more elongated towards apex; the basal joint long, the second small, the third 

 large, nearly as long as fourth and fifth combined. Pronotum almost a square ; 

 slightly wider posteriorly, smooth, with a median and latero-marginal sutures ; 

 mesonotum rectangular, wider than long, with median suture well developed ;
