HYMENOPTERA AND VESPID/E. 53 



apex of the pronotiim is rounded gradually, not obliquely 

 sloped, there is no tubercle on the top of the basal slope of 

 the 1^^ abdominal segment ; it is a smaller species, the tem- 

 ples are more gradually broadly rounded. Apparently also 

 there is a dijfference in the alar neuration ; in procera the \^^ 

 transverse cubital nervure is straight and oblique in front 

 and behind ; in patricialis it is much more rounded in front 

 and behind, there being no clear line of distinction between 

 the two slopes ; in procera the 2"'^ transverse cubital has a 

 small, rounded projection below the middle, while in patridalis 

 the lower half roundly projects outwardly. 



Triscolia speciosa Sm. 



Riouw Lingo. (Teysraan). 

 One specimen. 



Triscolia opalina Sm. 



A specimen from Palembang is probably T. velutina Sauss. 

 I am, however, unable to separate it satisfactorily from 

 T. opalina Sm. from Borneo. No doubt T. intrudens Sm. from 

 Ceram is another form. 



Triscolia rnhigiiiosa Fab. 



Tengger-iiionntains. Java. (Descher leg.). Several Java 

 examples (Dr. Ploem leg.). 



Triscolia capitata Guér. 



Ardjuno, Java. (Scheepmaker leg.). 

 One example.
