582 Longicornia Malay ana. 



genus, the males — now unknown — will probably be found 

 to have dilated antennge. The third joint of those organs 

 terminating in a slender obtuse process, and the shortness 

 of the joint itself compared to the fourth, are also charac- 

 ters which, although probably only of generic value, are 

 nevertheless foreign to the Prothemince.

 above ; head without pubescence ; prothorax with a slight 

 longitudinal carina, a little rounded at the sides, the base 

 closely covered with a band of white hairs; scutellum

 abdominal segments with a whitish pile ; legs black ;

 first two joints reddish-brown, the third and fourth glossy 

 black, the fifth and sixth dark, the remainder white.

CaLLI CHROMING. 



The species of this subfamily in the collection are com- 

 prised in two genera out of the twenty-nine enumerated 

 by M. Lacordaire. Of these two genera I have described 

 here twenty-two species, leaving a few not so well-marked 

 for future consideration. There is a strong resemblance 

 between many of the species, and their discrimination, 

 in many cases, is very difficult. They are nearly all very 

 handsome, mostly bright metallic-green, and emit an 

 agreeable odour, due to certain glands situate behind 

 the posterior angles of the metasternum, and communi- 

 cating by pores with the surface. Two species are found 

 in Europe, a few only in America, the remainder are 

 African and Asiatic ; none in Australia. * 



* Mr. White has described a " Callichroma Cinderella" from "Aus- 

 tralia (N. E. Coast) (Coll. Driug)," but this locality requires corroboration.
