PLATYZOSTERIA SUBARMATA sp. nov. 



Nigro-ca.staneous, nitid, a few scattered impressed dots on the thoracic 

 tergites, lateral and posterior margins of all the tergites ciliate, not scabrous. Head 

 nigro-castaneous ocelliform spots yellow, antenna; rufo-castaneous, with about the 

 proximal J of their length darker. Thoracic tergites somewhat rufous- laterally, 

 darker on the disc. No vestiges of tegmina or wings. Abdominal tergites with a 

 darker band occupying the posterior half ; margins more rufous, especially towards 

 the ape.x of the abdomen, where the posterior lateral angles of the tergites and the 

 distal portions of the appendages are rufo-castaneoiis. Angles of abdominal tergites 

 5, 6, and 7 backwardly produced ; lateral margins of tergites (i and 7 not denticulate. 

 Supra anal lamina of ,j (Text-fig. 4) tiiangular, ]iro(luced into two long spines, with 

 or without a spine on the lateral margin, extending beyond the cerci which" are 

 very long. Subgenital lamina of i^ (Text-fig. 5) quadrate, emarginate, styles long, 

 acuminate, slightly incuived, inserted laterally, and without a s])ine at the base. 

 C'oxa3 margined with yellow, legs castaneous, anterior and middle femora paler than 

 posterior femoia. Distal tarsal joints paler than the metatarsus, which is rather 

 long, not spined beneath, and with its })ulvillus occupying almost the whole of its 

 length. Arolia large.
