184 iscrnopsoPHA ritsemae. 



A single female specimen was sent to the Leyden Museum 

 by Mr. Hoedt from the island Soela Besi (Soela-Arcliipe- 

 lago between Celebes and Halmaheira) ; this is the most 

 westward locality Ischiopsopha-ST^ecies are recorded from , 

 with the exception however of the Cambodian 1. Camhodiensis 

 Wall., but I cannot help having much doubt for the exact- 

 ness of that aberrant locality. 



I am very glad having an opportunity to name this fine 

 insect in honour of my friend Mr. C. Ritsema Cz., the well- 

 known entomologist of the Leyden Museum.

 and with more distant punctures on the vertex. 



The prothorax subconvex , with the sides broadly rounded , 

 the posterior angles obtuse, the median lobe triangularly 

 emargiuated at the top; in the middle very finely and spa-
