Shilling black, with a blood-red triangular patch upon each side 

 of the prouotum (of which the base extends along nearly the 

 w hole lateral margin, the t\\o apices approximating a little before 

 the basal margin) and a large bright yellow patch nearly half the 

 length of the elytra placed before the middle of each and reaching 

 the outer but not the inner margin, the inner angles of each patch 

 being excised. The last segment of the abdomen is deep red 

 above and below. 



The dypeus is quadrate and straight in front, with the angles 

 broadly rounded, the surface is indistinctly punctured and the 

 central part gently raised. The iJronotum is smooth, with very 

 line, scattered punctures, its sides gently sinuated and bordered 

 with a lateral line upon the anterior half only. The scutellum is 

 broad and smooth and the elytra are very faintly seriately punc- 

 tured, with the apices slightly rugose. The pygid'mm is finely 

 transvei'sely strigose, the metasternum has very large deep punc- 

 tures at the sides, and each ventral segment has a row of punctures 

 at the middle. 



Length 16-3 8 mm.; breadth 8-9 mra. 



Travancoee : Trivandrura (June) ; Ceylon. 



Type in the Copenhagen Museum ; that of confusa in the 

 Oxford Museum, that of bimaculata in coll. K. Oberthlir. 



The upper surface is less strongly punctured than that of 

 D. cuvera, Newin., the yellow patches upon the elytra are much 

 smaller and the lateral striae of the pronotum are obsolete behind. 



Westwood was unable to recognise this species as that previously 

 described by Wiedemann, but thei'e is no apparent reason for 

 his doubt.
