Tegmina rufo-testaceous, infuscated at base, fifteen costal veins, dis-

and apical tarsal joints rufous. Sub-genital lamina small, narrow, 
quadrate, with two styles.

Blatta bipunctata, Walker, 1. c. p. 141 (1869). 
. MACASSAR, CELEBES (Wallace). 
The species is rather convex, the marginal field of the 
tegmina is broad, the veins of the discoidal field are very 
indistinct, a triangular apical area is present in the wings, 
the supra-anal lamina is short and transverse and the 
femora are sparsely armed, which characters taken in 
conjunction may be considered as diagnostic of the genus 
Pseudectobia.

2. SINGAPORE (Wallace). 
In Singapore examples the disc of the abdomen beneath 
is testaceous, whereas in examples from Borneo (= Jati- 
caput, Br.) this is rufous, otherwise the two forms are 
identical.
