It is impossible to say whether the specimen which I have placed 

 under this name, or the one described below (C. dubia), is the true 

 insularis. as both seem to answer to the descriptions given by Gruerin. 

 The specimen which I here consider as insularis, differs from tbe fol- 

 lowing species by the mesothorax being more bluish, and the punc- 

 tures of the abdomen not so dense, while in dubia they become very 

 fine and dense towards the apical margins of the segments, and the 

 spaces between the punctures are distinctly punctured, thereby giv- 

 ing the abdomen a much rougher appearance than in insularis, 

 although the interstices between the punctures of the latter are also 

 punctured, but not so distinctly. The third segment of dubia is almost 

 entirely green, while in insularis the apical margin only is green, and 

 the six teeth on the apical margin in the latter species, are rather 

 longer and more acute ; otherwise there is scarcely any difference be- 

 tween the two species. 



Chrysis dubia. n. sp. 



Robust, green, dorsal surface of the second and third abdominal segments 

 deep azure-blue; the face, pectus and pleura, golden-green; wings subh valine. 



Female. — Head broad, pubescent, green, faintly tinged with blue on 

 the vertex across which, below the ocelli, there is a twice angular ca- 

 rina throwing upon each side towards the ocelli a short carina; the 

 excavation behind the antennae finely rugulose and brilliant golden- 

 green, the punctures of the vertex and occiput are dense and coarse ; 

 mandibles piceous, green at base ; cheeks carinate ; antennae blackish.
