This handsome species, though agreeing closely with R. hasalis 

 (Haan) in pronotal form, is clearly a member of a distinct species 

 group, distinguished by the greater definition of the lateral wings 

 of the pronotum from the primitive portion, the distinct and greater 

 serrulation of the pronotal margins, the serrulate costal margin 

 of the tegmina and clear hyaline wings, not tinged with pink as in 

 basalis and its closer allies. 



The present specimens, in addition, have the stigma buffy without 

 adjacent suffusions of any kind, but this feature would appear to 

 be variable, as Giglio-Tos records specimens from Timor with stigma 

 showing blackish brown suffusions cephalad and caudad, as is char- 

 acteristic for hasalis. 



From the data given in the literature, the size variation would 

 appeaT to be considerable. The measurements of the specimens here 

 recorded are: length of body, cT 71.5, 9 70-75.5; length of pro- 

 notum, cf 24.1, 9 25.2-26.2; greatest width of pronotum, cf 15.6, 

 9 17.2-18.3; length of tegmen, cf 64.1, 9 49.7-50.2; width of 

 tegminal marginal field, cf 4.9, 9 5.9-6.3 mm.
