A short wide insect with the prothorax very small in comparison 

 of the elytra. Less darkly coloured than the preceding, and also 

 smaller, with the prothorax not so strongly transverse and 

 differently shaped in the hinder part. In latus the base on either 

 side runs from the hind angle obliquely (and a little sinuately) 

 hindward and inward, the oblique lines thus formed meeting the 

 median piece of the base almost subangularly ; thus the hind angles 

 of the prothorax not only are a good deal rounded off, but are 

 formed by lines inclined to each other at a very obtuse angle ; in 

 lindensis the base on either side runs from the hind angle directly 

 inward and not (or scarcely) at all hindward until it is slightly 

 deflected hindward to form a very feeble median lobe ; the hind 

 angles thus being formed by lines inclined to each other at a much 

 less obtuse angle. In both sjjecies the actual junction of the base 

 and sides is a good deal rounded off.

The decidedly bright blue iridescence of the elytra seems to be 

 a good character for this insect. R. cyathodera, Chaud., is said to 

 be " subiridescent " only, and besides it is a considerably larger
