C. ornata, that, without connecting links, it appears to be speci- 

 fically distinct; several examples from Devonshire ai-e in the 

 Museum, all agreeing in having the legs entirely yellow, dashed 

 with ferruginous, a large ovate macula on the sides of the meta- 

 thorax, and four yellow emarginate bands on the abdomen; 

 they agree with C. ornata in having a semicircular carina at the 

 base of the second segment beneath.
