angles rounded, posterior almost right angles ; on the upper 

 surface the central area inclosed between the semilunar patches is 

 almost iinpunctate or very finely punctate, the lateral areas are 

 more coarsely and thickly punctate. Scutellum triangular, smooth 

 and impunctate. Elytra at the base about twice as broad as 

 the width of the prothorax ; disposition of the blue-black patches 

 on each elytron as follows : on the bas;i! area two patches, the 

 first covering the humerus and a little area round it and the 

 second (the largest patch on the elytron) placed near the suture 

 obliquely behind the first; on the middle area, lying in a similar 

 oblique line, there are three patches almost of equal size ; finally, 

 on the apical area there are two more, situated in a third oblique 

 line, one on the lateral margin and the other near the suture, the 

 former overflowing the margin and staining a little portion of the 

 epipleuron ; below the humerus there is a patch which stains partly 

 the epipleuron and partly the elytral margin, and sometimes this 

 patch is confluent with adjoining patch of the second oblique line. 

 The sculpturing is as follows: on each elytron (1) a short 

 scutellar row of punctures, (2) one row along the suture, (3) 

 another row parallel to the sutural row, (4) along the lateral 

 margin two rows running parallel the whole length, the interstice 

 between them being slightly convexly raised ; rest of the surface 

 confusedly punctate, except on the basal area where an arrange- 

 ment in rows is observable. Underside more shining than the 

 upper, generally impunctate; the disposition of the blue-black 

 spots and patches has been touched on m the short colour 

 diagnosis given above.

The location of the type is unknown to me. 



Variation : in some specimens the underside is without any 

 markings. In the two specimens from Assam in the collection of 

 the British Museum most of the spots and patches on the upper- 

 sid« have disappeared except the humeral, subhumeral and one 

 apical, on the other hand the patch on the head is much enlarged 

 and the underside also is almost suffused with blue-black. Some- 

 times the upper surface of the head is entirely blue-black, and 

 the patches on the pronotum have all fused, covering a large 

 area .
