very slender, and consisting of four joints, which is 

 likewise the case with the lahial pair ; spines of the 

 hinder legs pectinated on the inner side. 



To exemplify this genus we have represented a 

 new and splendid species from the collection of the 

 Rev. F. W. Hope, which, on account of its large 

 size and vivid colours, Mr. Westwood has named C. 

 nobilis. It is of an intense black, clothed with very 

 short velvet-like plush; the three terminal segments 

 of the abdomen brick-red, and the wings black, with 

 an exceedingly brilliant purple gloss ; the length is 

 about thirteen lines; expanse of the wings nearly 

 two inches ; the second submarginal cell receives the 

 first recurrent nerve, and the second recurrent nerve 

 is confluent with the nerve which closes the third 

 submarginal cell ; the hind legs are extremely hirsute, 

 with two long and acute tibial calcaria, both denti- 

 culated, but one more strongly than the other ; the 

 upper lip is triangular; the mandibles with four 

 teeth, the two inferior ones strongest and obtuse; 

 the maxillary palpi short, very slender, and four- 

 jointed. 



Locality doubtful; but in all probability South 

 America.
