of the Hymenopterous genera Cleptes, ^-c. 471 



Guerin's species ; it is entirely green aBove and beneath, 

 with tints of blue on the thorax ; the antennre beyond the 

 three basal joints being black, the middle division of the 

 mesothorax is blue black, inclining to purple : the apical 

 segment of the abdomen is golden-green. The thorax is 

 entirely covered with strong confluent punctures, as are 

 also the tegulre ; the wings smoky, with black nervures. 

 Abdomen : the first and second segments rather more 

 closely and strongly punctured than in Stilhum ame~ 

 thystina, the third segment entirely covered with fine 

 confluent punctures. The lateral angles of the basal 

 segment rounded, in S. amethystina they are acute. 



Neither Guerin nor Brulle mention the difierent struc- 

 ture of the basal segment of the abdomen ; this is probably 

 an oversight, if not, the insect I describe will prove to be 

 a new species. 



Note. — The types of the species distinguished by a * are iu the British 

 Museum.
