(J . Labium light oehreous. Labruin, face aud frons anteriorly 

 very light greenish yellow ; a very narrow aud incomplete black line 

 at base of labruni. On dorsal surface of frons a black basal band, 

 narrowly descending along the eyes ; fused to that band an almost 

 circular black spot ; rather widely separated from this spot a narrow 

 black line on anterior frontal ridge; the black l)asal spot surrounded 

 by a narrow light yellow line, which is limited anteriorly by the 

 black line on frontal ridge, laterally by greyish blue shades, which do 

 not fully reach the basal black baud. Vertex yellow above, black in 

 front. Occipital triangle yellow. Occiput ferruginous with black 

 margin. Thorax dull olivaceous brown, with light yellow markings ; 

 narrow ante-humeral bauds to about mid-height, slightly nearer to 

 median than to humeral suture ; transverse spot in angle between 

 alar sinus aud dorsal end of humeral suture ; humeral suture narrowly 

 lined with oehreous; two almost equally broad (1 mm.) lateral bauds, 

 passing from light yellow to more greenish shades dorsally, distinctly 

 lined with dark brown in ventral half ; first band in middle of 

 mesepimeron, bent at mid-height to more nearly vertical direction ; 

 second band on middle of metepimeron, slightly widened dorsally and 

 slightly concave anteriorly ; a triangular metejsisternal spot behind 

 dorsal half of mesepimeral band. Metasterna dark brown with two 

 small yellow spots. Legs roljust ; femora ferruginous, black at the 

 joints ; internal side of first pair light yellow ; tibiae and tarsi black. 



Abdominal segments 1-2 moderately inflated, 3 considerably con- 

 tracted, end of 3 to 10 robust with parallel sides. Colour of living 

 insect probably green (or blue) aud dark brown in about equal parts, 

 in dead and discoloured specimen dull olivaceous aud dull brownisli 

 ferruginous. Light (green ?) colour distributed as follows : sides of 

 segment 1 ; complete basal ring on 2, to transverse carina, laterally 

 to the earlets ; 3 large mid-dorsal anterior spot to transverse cariua, 

 two siuall triangular spots behind carina, large terminal, lateral, 

 semicircular spots, touching at mid-dorsal line ; 4-7 complete basal 

 ring to carina, behind carina each side two median spots, the larger 

 one lateral, the smaller one dorsal, and a semicircular terminal spot; 

 8 small lateral anterior aud large semicircular terminal spot ; 9 the 

 semicircular termiual spots alone ; 10 ferruginous on anterior, light 

 green on posterior half, the two colours separated by a narrow black 

 line, which is continued posteriorly on the mid-dorsal carina. Ventral 

 surface blackish, .second segment dull brown, and also basal lateral small 

 spots on segments 4-8. On first ventral plate a transverse, anteriorly 

 convex field covered with numerous small black spiuules. Earlets of 

 second segment small with three dorsally directed spines. Margin of
