This may prove to be the $ of the preceding, but the 

 tarsi are entirely pale, and both my specimens are much 

 discoloured ; they are very closely allied to floricola, but 

 the post-scutellum is slightly raised and the mesopleurse 

 are not carinated under the yellow spot as in that species.
