duced backwards, anteriorly truncate ; disc with a large castaneous 

 cordifoi'in macula, all the margins tcstaceo -hyaline. Tegmina 

 castaneous with the mediastinal area and numerous minute maculae 

 testaceous; 15 costals , anterior ulnar vein with 4 longitudinal 

 rami , posterior ulnar simple. Wings infuscated, 10 costals, the 

 distal 4 bifurcate, ulnar vein 4-ramose, a distinct apical triangle. 

 Abdomen above and beneath piceous. Supra-anal lamina trigonal. 

 Cerci moderate , highly acuminate at apex. Legs piceous , tarsi 

 testaceous at base. 



Total length 11,2 mm; length of tegmina 8 mm; pronotum 

 2,9 X 3,9 mm. 



Peru, Callanga. 



Probably the nearest ally of this species is P. obscura Sauss. 

 but the backward production of the pronotum and the apical 

 triangle of the wing are unusual features in this genus. 



Sub-fam. Blattinae.

 cf. Head and antennae piceous, ocelli and a band between 

 the eyes ochreous, mouth-parts rufo-castaneous. Pronotum trape- 

 zoidal , anteriorly not covering vertex of head , bright ochreous 

 with a large sub-cordiform piceous macula occupying the centre 

 of the disc. Tegmina semi-corneous barely exceeding apex of 

 abdomen, castaneous, densely reticulate-punctate. Wings as long 

 as tegmina, anterior part semi-corneous with rounded apex, pos- 

 terior part somewhat reduced. Metanotum with a quadrangular 

 membranous flap attached to the middle of the posterior margin. 

 Abdomen piceous , supra-anal lamina quadrangular faintly eniar- 

 ginate, exceeded by the sub-genital lamina which is quadrangular, 

 posterior angles acute, styles stout , lateral. Cerci rather short 

 and blunt. Coxae and femora rufous , tibiae and tarsi piceous. 

 Femoral spines short and rather weak , tibial spines long and 

 stronger, the innermost apical calcar on the outer aspect of the 

 . posterior tibiae almost as long as the metatarsus. Posterior meta- 

 tarsus shorter than remaining joints, bi-seriately spined beneath, 

 pul villi very large. 



$. Similar , but discoidal macula of the pronotum much 

 larger. Tegmina very short , concavely and obliquely truncate, 

 not extending beyond the 1^' abdominal tergite. Wings rudimen- 

 tary. The first 3 abdominal tergites banded with ochreous, some 

 small maculae of the same colour on the 4'*' tergite. Dorsum 

 of abdomen rugose, posterior angles of b^^ — 7"' tergites spinously 

 produced, supra-anal lamina triangular, apex notched, exceeding
