Blattidae. 137 



The species can be distinguished from P. scabriuscuki TEPP. by the 

 absence of scabrous points, by the non-emarginate c5 supra-anal lamina, 

 and by the form of the subgenital lamina: from P. obscura (TEPP.) it 

 can be distinguished by the last two characters mentioned and by the 

 castaneous legs, whilst P. morosa n. sp. differs in having a spinous rf 

 supra-anal lamina.

Plate XIII, Fig. 14. 



$. Piceous with disc of the thoracic and first 4 abdominal tergites 

 rufo-castaneous ; nitid. impunctate. Lateral margins of thoracic tergites 

 and of abdominal tergites 2 5 testaceous. Head testaceous, vertex and 

 a band above the clypeus castaneous. Antennae considerably exceeding 

 the body in length, basal joints testaceous, remainder castaneous. Tegminal 

 rudiments absent. Supra-anal lamina triangular, lateral margins entire, 

 apex truncate and deeply emarginate, a minute spine at each posterior angle. 

 Cerci exceeding the lamina. Subgenital lamina subquadrate, apex widely 

 emarginate, styles moderate. Posterior margin of 7 th abdominal tergite 

 markedly sinuate, lateral margins not serrate. Legs testaceous, posterior 

 tibiae and tarsi castaneous; posterior tibiae slightly flattened and expanded. 

 Length 24 mm. ; prouotuni 7 mm. X 9.5 nim. 



The form of the supra-anal lamina distinguishes this species from its 

 nearest allies P. albomarginata BR. and P. Irunnea TEPP.
