Genus Archibla.tta, Voll. 

 ? Archiblatta parva, sp. n. 



? . Rufo-testaceous, all the segments margined and 

 speckled with castaneous. Head castaneous, the vertex 

 paler, finely punctate, nitid ; antennas and mouth-parts rufo- 

 castaneous, antennoe slender, setaceous [mutilated]. Eyes 

 further apart than antennal sockets. Upper surface of body 

 scabrous, nitid. Pronotum trapezoidal, anteriorly truncate, 

 posterior margin slightly obtusely angled ; posterior angles of 

 all the thoracic tergites slightly produced. Posterior angles 

 of abdominal tergites not produced ; supra-anal lamina sub- 

 quadrate, posteriorly emarginate, angles rounded, dark casta- 

 neous in colour, margined with testaceous. Body beneath 

 and legs uniform castaneous, abdominal sternites laterally 

 scabrous ; antepenultimate sternite with a large deep puncture 

 on each side, bordering the subgenital valves. Cerci shorter 

 than the supra-anal lamina. Front femora with a complete 

 row of spines on anterior margin beneath, one on the poste- 

 rior margin ; raid femora with 4-5 spines on anterior, 2-3 on 

 posterior margin ; hind femora with 4 spines on anterior, 1 

 on posterior margin ; all these spines very smalh Tibial 

 spines in three rows, but the middle row very incomplete. 

 Posterior metatarsus equal to remaining joints ; pulvilli large, 

 occupying nearly the entire length of every joint. 



Total length 23 mm. ; pronotum 6 x 8'5 mm. 



Towranna plains, W. Australia (E. Clement) . Type in 

 Oxford Museum. 



I place this very curious insect provisionally in xirchi- 

 hlatta, but in many of its characters it does not conform to 

 that genus, and eventually it may be necessary to erect a 

 new genus for its reception.
