light buff distad along the mediastine vein. Dorsal surface of abdomen raw 

 umber, with lateral margins rather broadly warm buff. Head with face shining 

 blackish with a chestnut tinge, becoming slightly paler on occiput, eyes prout's 

 brown, ocelli light buff, antennae uniform cinnamon brown, genae, mouthparts 

 and limbs brussels brown. Ventral surface of abdomen shining black, shading 

 to brussels brown meso-proximad, rather broadly margined with warm buff, 

 this continued as a narrow marginal line on the subgenital plate. 



9 . Allotype. — Pronotum with mesal jiortion shining black shading to deep 

 carob brown meso-caudad, lateral margins of this marking not showing the 

 angulate production before the mesal point as strongly as in the male and 

 feebly convex divergent caudad; lateral wings antimony yellow, punctae and 

 cingulate margin bay. Tegmina with anal field carob brown, marginal field 

 antimony yellow, punctae and larger distal flecks bay, intervening portion be- 

 tween these areas blackish tinged with carob brown. Wings minute, vestigial, 

 irregular pads. Abdomen entirely shining black, showing a very faint carob 

 brown tinge. Head with face the same color, shading to carob brown on occi- 

 put, ocelli and mouthparts clay color. Coxae deep bay black, other portions 

 of limbs and antennae deep bay. 



In the majority of the females before us, the angulate produc- 

 tion of the dark pronotal marking is not as decided as in the male. 

 Several are not as dark as the allotype, one individual being much 

 paler, with dark portions of pronotum and tegmina bay and 

 dorsal surface of abdomen heavily tessellate with buffy. 



Speciinens Examined: 11; 1 male, 7 females and 3 immature individuals.

POROBLATTA« new genus 



The present genus is knoAvn only from the female, which agrees 

 with that sex in the genus Colapterublatta in the type of head, 

 pronotum with simple lateral wings, abdomen and limbs and their 

 armament. It differs in the more slender form, greater pronotal 

 convexity, and more slender and more strongly convex abdomen. 



Closer affinity is shown to the female sex in Acroporohlatta, 

 which has, however, a proportionately much larger head, more 

 strongly hooded pronotum with lateral, longitudinal gland-like 

 swelling and lacks tegmina. 



Genotype. — Porohlattn cylindrica new species.
