160 Mr. R. Shelford on new 
Genus ARCHIBLATTA, Voll. 
? Archiblatta parva, sp. n. 
?. Rufo-testaceous, all the segments margined and 
speckled with castaneous. Head castaneous, the vertex 
paler, finely punctate, nitid ; antenne and mouth-parts rufo- 
castaneous, antennze 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 ; mid 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 small. 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 (#4. Clement). Type in 
Oxford Museum. 
I place this very curious insect provisionally in <Archi- 
blatta, but in many of its characters it does not cenform to 
that genus, and eventually it may be necessary to erect a 
new genus for its reception.
