On Some Hymenoptera From the 

 Raffles Museum, Singapore. 



By F. Cameron. 



Dr. Hanitsch having sent me to be named some undeter- 

 mined Hymenoptera from Singapore, I give a list of them as 

 a small contribution towards the knowledge of the Hymenop- 

 terous Fauna of the Island. 



Evania appendig aster Lin. A cosmopolitan parasite in the 

 egg-cases of Cockroaches. 



Stilbum splendidum, Fab. 



Macromeris violocea, Lep. 



Discolia decorata, Burm. 



This species (which = D. Jlavopicta Lm.) is in the collec- 

 tion of the Raffles Museum from the Dindings. 



I think it very probable that D. ergenna, Com. (Journ. St. 

 Br. Royal Asiat. Soc, 1902, p. 82) is its male. 



This species is recorded by Magretti (Ann. ch. Museo 

 Civico di Storia Nat. di Genova (2) xii, 243) from Schwegoo, 

 Burma ; but it is not included by Bingham in the Fauna of 

 British India, Hymen. It has been reported from Java and 

 Sumatra. 



Salins flavus, Fab. 



Sceliphron violaceum, Fab. 



Irypoxylon petiolatnm, Sm. Found in the Museum Work- 

 shop. 



Piagetia ruficollis. sp. nov. 



Black the scape of the antenre, the greater part of the 

 clypeus, the prothorax, the mesonotum in front of the tegula?, 

 the tegulre, the abdominal petiole, except at the base, and the 



R ; A, Soc, No. 41, 1904.
