FLATAJIIA. 413 



costal, apical, and posterior inargius (broken near middle of eosta), 



a carved longitudinal discal fascia, and an apical submargiual 



curved fascia black ; wings creamy-white. 



Length excl. tegm. 10 to 16 ; exp. tegm. 39 to 57 millim. 

 Hah. Malabar {Brit. Mas.). Burma; Momeit (Dohei-t >/).-- 



iSumatra, Java. Borneo. 



The Malayan forms are a little darker in hue, with the black 



fasciae to the tegmina broader and less dislocated on costal 



marfrin. 



Division FLATARIA. 



I propose this division for a series of genera which have the 

 apical margins of the tegmina trimcate and not rounded; the 

 posterior angles of the apical margins are also always more or less 

 subacutely produced. 



The Flataria are principally represented in the Ethiopian and 

 Oriental Regions. 



iSi/aoi>sis of Genera. 



A. Head with the vertex more or less sub- 



acutely produced. 



a. Tegmina about, or nearly, twice as broad 



as long. 



a. Radial vein not emitting a longitudinal 



vein. 

 a'. Costal membrane about as broad as 



radial area, the hxtter reticulately 



veined I'hyllypha.nta, p. 414. 



b'. Costal membrane narrower than 



radial area, the latter obliquely 



reticulately veined Pulastya, p. 417. 



b. Radial vein emitting a longitudinal 



vein at a short distance from base . . Saluenis, p. 418.
