 lateral margin excepted), brown in $ , greenish-blackish in the

 broadly rounded behind, with a minute not retracted sutural spine. 

 Punctuation of the elytra fine, little visible (margin excepted) ; 

 pattern broad, as described above. Under side coppery, abdomen 

 bluish-cyaneous with the whole of the lateral parts of the pectoral 

 region of the metasternum and of the first 4-5 abdominal sternites 

 densely clothed with white bristles. First four segments of antennae 

 coppery; legs, cf , more greenish above, more coppery below, 9 as 

 well as almost all tibise and tarsi 9 cf more or less testaceous ; palpi 

 testaceous, only tips of last joint darkish.

The most remarkable feature is that even the greatest part 

 of the labrum becomes blackish (at least the base of both of the 

 lateral margins). A small patch near the base of the mandibles 

 seems always to be testaceous. The hind hips have onl}^ a 5^ellow tip.

The contrast between the obscure black (almost always with- 

 out any metallic lustre) coloration of the elytra and the enlarged 

 straw-like yellow humeral patch is very striking. The last is almost 

 as broad as long. Therates spinipennis versicolor, Bat., is des- 

 cribed as being larger than the typical form and metallic on the 

 disc of the elytra, which are not punctured and show a small humeral 

 spot.
