SILIS SIMPLEX. 109 



and it is more ou account of other characters that I as- 

 sign it to that genus. It is moreover very close in its size 

 and coloration to several species of veritable Silis , e. g. 

 S. ruficolUs F. from which it differs however (apart from 

 structure) in having the scutellum red, and the abdomen 

 black. 



Five specimens, three male two female, from Sidjoen- 

 djoeug, the district of Rawas and Koetoer (Sum. Exp.). 



26. Silis simplex ^ sp. u. 



Totus testaceus; ocuhs nigris, alis fuscis , an tennis fili- 

 formibus. — Long. 7 — 8 millim. (f Q. 



Mas , oculis subglobosis , magis prominulis , prothoracis 

 lateribus in medio obliquiter incisis, segmento ventrali 

 apicali fisso. 



This is a sufficiently typical Silis , and in its wholly 

 pale colour is unlike any other known to me. It has the 

 facies of the Europaean Tel. bicolor. 



Specimens from Moeara Laboe, Peak of Indrapoera, the 

 district of Rawas and Koetoer (Sum. Exp.). '
