Part 1. 

 [Concluded from vol. VI, page 256). 



11. Ctenophora annulosa, n. sp. 



Atra velutina; abdomine annulo basali aurantiaco; anten- 

 nis, polpis , pedibus halteribusque nigris; alls fuscis , macu- 

 lis sublimpides in cellularum medio. — Q. Long. 20,5 mm. 



Closely related to the two foregoing species ; the thorax, 

 however, is entirely black; on the contrary the posterior 

 half of the first abdominal segment and the anterior half 

 of the second one are orange. The wings are not so 

 broad and less dark; all the cells, except the costal ones, 

 have clear centres; neuration agreeing with that of in- 

 cunctans and velutina. 



A 9 from Java (Blume). 



Prionota , n. g. 

 (•n-piovQTog , serrulated). 



G. Ctenophorae ajfinis ^ sed antennae in utroque sexu 

 forte nodulosae vel serratae, in mare non ramulosae.
