2. Chrysis obscura. C. viridis, purpureo variegata; capite thora- 

 ceque confertissime punctulatis, segmentis abdominis dehcatule punc- 

 tatis, apice sex-dentato ; alis subhyalinis. 



Length 5 hues. Green, with shades of blue and blue-black ; beneath 

 entirely of a brilliant green ; the vertex with a large blue-black ma- 

 cula, which encloses the ocelli. The prothorax with a transverse black

 blue-black with the apical margins of the segments bright green, the 

 apex ai-med with six equal acute teeth ; the postscutellum rounded. 



Hab. Makassar. 



This species is apparently most closely allied to the C. Schibdtei of 

 Dahlbom, but it is much less briUiant in colour and has no vestige of 

 a golden macula on the second segment of the abdomen ; the teeth at 

 the apex are very different, being of equal size and at equal distance 

 fi'om each other. 



3. Chrysis fumipennis. C. Isete purpurea ; capite thoraceque fortiter, 

 abdomine delicatule punctatis ; alis fusco-hyalinis. 



Length 4| hnes. Opake purple-blue ; the legs and two basal joints of 

 the antennae bright green; the abdomen green beneath, the vertex

 into a triangular acute tooth. Abdomen: the segments darkest at 

 their base ; the apical margin of the terminal segment rounded, and 

 armed with four minute acute teeth, 



Hab. Makassar. 



This species is distinguished by a much broader and more depressed form 

 than is usual in the genus.

 angles of the metathorax acute. Abdomen : the segments blue-green, 

 with the apical portion of each bright green, the margin of the apical 

 one tridentate. 



Hab. Makassar. 



This species is closely allied to the C. Bohemanni of Dahlbom ; but it is 

 larger, more robust, and the apical segment of the abdomen is not
