have not been able to satisfy myself that this specimen is certainly 

 the true didyma, but as I had no sufficient time to examine it fully

 green. Rest of head and upper surface of eyes black, except the 

 anteclypeus and genae which are silvery blue, and a small yellow 

 transverse post-ocular mark. 



Prothorax entirely black. 



Thorax black with a pair of oval-oblong, silvery blue spots 

 on either side of the mid-dorsal carina, extending from below for

 ally divided into two by a black line along the second lateral 

 suture.

 darker than lower parts.

 their border coalesce with the antehumeral band. Sides and under 

 surface of thorax pale yellow, with vestige of black stripe along the 

 second lateral suture.

 ro whitish-yellow, 



$ Adult. — ^Coloured much as the j^oung male, but with the

 and the posterior half of 9 and the whole of 10 is of a whitish- 

 yellow.
