CONTRIBUTIONS TO A KNOWLEDGE OF THE HYMENOPTERA OF BRA- 

 ZIL, NO. 6.-A COLLECTION FROM RIO GRANDE 

 DO SUL AND SAO PAULO. 



BY WILLIAM J. FOX. 



The small collection on which the present paper is based was 

 received for identification from the Museu Paulista of Sao Paulo, 

 Brazil, and is of interest through the large number of species which 

 are not represented in the Herbert Smith collection, on which the 

 previous papers of this series are based, which would seemingly 

 indicate that the fauna of the southeastern region of Brazil differs 

 considerably from that of the more inland northern States, Matto 

 Grosso and Para, where the Smith collection was largely made. 



Unless otherwise stated, the specimens were collected in Rio 

 Grande do Sul. The types of new species are the property of the 

 Museu Paulista.

 Elis Servillii Lep. 

 Elis Gerstaeckeri Sauss.

The specimen before me agrees with Saussure's description except 

 that it is much larger than any of his specimens; it measures 45 

 mm. in length.

 the third to seventh or eighth fuscous, the remaining joints fulvous;

 by a distance almost equalling its width, and its outer margin is just 

 about in the centre of anterior Aving; in the hind wing this band is 

 somewhat broader; pubescence throughout dark 



Clypeus emarginate, but not deeply; frontal impression strong.
