much finer, the posterior one with the exception of the small dis- 

 coidal impression is wanting, the base is much less narrowed before 

 the posterior angles, and the sculpture is more finely granulate ; the 

 elytra are broader, more ovate, much planer, and with the shoulders 

 less distinct, the apical spines are longer, the margin is not inflexed 

 and declivous, the anterior half, except towards the suture, has a 

 moderately few punctures, while the posterior one, including the 

 sutural part, has very few punctures broadly scattered, the patches 

 are flavous, the humeral spot small, the median marginal macule is 

 oblong and larger, the apical one a little smaller. Colour above dark 

 aeneous, the margin of the elytra slightly greenish violaceous, the 

 under part of it violaceous ; pectus and abdomen denuded, labrum 

 flavous, antennae, coxae, legs, and palpi testaceous brown. Male.

"Allied to C. sexmaculata, Chaud., but it is very much larger; 

 the head and prothorax are a little more roughly sculptured ; the 

 labrum is hardly shorter, the sculpture of the elytra is much rougher 

 and deeper, the sutural spine of the female is very much shorter, 

 and there is one small, marginal, flavous spot before the apex ; the 

 whole body is a beautifully cyaneous blue opaque above, shining 

 beneath and on the legs, and the last abdominal segments are a little 

 viridescent. The male differs from the female in being of a more 

 slender shape, the elytra are less dilated in the middle, more roughly 

 sculptured beyond the median part, the sutural spine is extremely 

 long, the labrum shorter, and the marginal flavous macule much 

 larger. Length 16|— 17ij mm.

Similar to M. bennigseni, Horn, but differs by the totally filiform 

 shape of the antennae (in M. bennigseni they are nearly filiform in 

 the male, and hardly foliate in the female), the vertex of the head is 

 more deeply rugose transversely ; the prothorax which is hardly
