1943. Pterilia signata, sp. u. 



Closely reseuabling P. ceylonensis, but differing in the following 

 characters ; — The margin of the costal membrane is considerably 

 less angularly excavate ; the central carination to face almost 

 obsolete behind middle; tegmina (excluding costal membrane) 

 coucolorous, with some small but prominent black spots, of which 

 the principal are three pairs arranged on each side of the median 

 suture, and three more spots placed wide apart but in longitudinal 

 series on the disk of each tegmeu ; legs annulated with piceous, 

 the posterior femora nearly wholly piceous. 



Length iucl. tegm. 10 millim.

1944. Pterilia piceata, sp. n. 



Head \\it\\ the vertex olivaceous, the anterior margin narrowly 

 and the lateral areas broadly piceous ; face much sprinkled and 

 mottled with piceous, the carinations piceous, the central carination 

 percurrent but less developed behind middle ; clypeus piceous, its 

 latex'al margins ochraceous ; pronotum and mesonotum piceous ; 

 legs piceous, slightly mottled at parts with ochraceous ; tegmina 

 piceous, an obscure costal spot before middle and a large elongate 

 costal spot behind middle, which almost reaches apex, ochraceous, 

 costal membrane hyaline with the transverse veins piceous, the 

 venation of the tegmina is wholly piceous except on the posterior 

 ochraceous costal spot, where it is virescent ; the lateral elevations 

 of the vertex of head are very prominent and subacute.

BistribiUion. Ceylon. 



" Ver}^ like PleriUa, but distinguished from that genus by the 

 front of the head, which is drawn out at an acute angle, before its 

 apex there is an angularly broken or interrupted transverse ridge, 

 a similar ridge at back of neck with the corners directed forward ; 

 the front angles of face are not produced into a point as in 

 Pterilia ; at base of mesonotum there is a transverse keel con- 

 necting the short lateral keels together ; tegmina as in Pterilia, 

 but the callosities in clavus absent ; posterior tibite with two 

 spines.*' {Melichar.)
