This and the two preceding species are all very closely 
allied. They are fulvo-testaceous insects about 17 mm. 
in total length with very long slender antennz and with 
the tegmina projecting considerably beyond the end of the 
body; the venation of the tegmina is the same in all 
species, there being twenty to twenty-one costal veins, 
eight discoidal longitudinal sectors and the radial vein is 
bifurcated. 
The following may be considered the differential 
characters of the three species : 
Pronotum with disc fusco-castaneous, a W-shaped 
mark and central line testaceous, margins testaceous. 
Coxe not spotted. Supra-anal lamina narrow, 
produced, triangular ; sub-genital lamina irregular, 
deeply cleft ; titillator nearly straight. . . . . P. elegans 
Pronotum with disc rufo-castaneous, a dumb-bell- 
shaped mark and margins testaceous. Coxe not 
spotted. Supra-anal lamina incised at apex. . . P. picticollis. 
Pronotum fulvous with irregular paler marking 
on disc. Coxe spotted with castaneous. Supra-anal 
lamina broad, produced, triangular; sub-genital 
lamina narrow, not cleft ; titillator strongly curved P. quttifera.

This is closely allied to P. hieroglyphica, Br. but the 
head and pronotum are much more heavily marked with 
castaneous and the femora have their posterior margins 
marked with fuscous,

Blatta obtusifrons, Walker, |. c. p. 226 (1868). 
2. SARAWAK (Wallace). 
Fulvo-testaceous. Head castaneous, antennze twice as long as the 
body. Pronotum trapezoidal, barely covering vertex of head, 
posterior margin very slightly angled, sides only slightly deflexed,
