Åppendix. 



On some type-species of the genus Seolia and Belenogaster 

 in the Roy. Mus. at Stockholm. 



When studying the hymenoptera in the previous paper I 

 have einbraced an opportunity of exaniining some old type- 

 specimens belonging to the R. Mus. at Stockholm. First of 

 all 1 may mention two species of the genus Seolia, which 

 have hitherto been regarded as very dubious ones. They are 

 described by J. W. Dalman in Analecta entomologica, Sthlm 

 1823 p. 90 No 103 and 104. The names of the species are 

 Seolia leonina and erythrogaster. 



Of these species I have with certainty only recognised 

 Se. erythr o gast er. Any species with the name Se. leonina 

 seems not to exist in the Museum, but there is a species, 

 that Dalman has called S. regalis, which is minutely agree- 

 ing with the description published by Dalman. 



This name was only an occasional one and it seems to 

 me to be very probable that Dalman when publishing his 

 work has changed the name to Se. leonina, but has forgotten 

 to change the name on the label in the collection. 



Both species are regarded by Saussure & Sichel as dubious 

 ones. As the descriptions of Dalman are too insufficient I 

 give here a little more detailed ones. The species belong to 

 the subgenus Dielis. Se. erythr o gast er is nearly related to 

 E. Grandidieri Sauss. or rufa Lep. and Se. leonina (Se. re- 

 galis) to Se. signat a Sm.
