Sent in large numbers from Chontales. By some en- 

 tomologists it has been considered the Cer. virens of 

 Linnasus ; but this is impossible, as Linneeus in Mus. Lud. 

 Ulr., distinctly says the hind femora are toothed, and his 

 insect is therefore a West African Callichroriia. 



Callichroma cosmicum, White, Cat. Long. Col. Brit. 

 Mus. p. 158. — Also common in collections from Chontales. 

 This species is found also in New- Granada. 



Callichroma cyanomelas , White, Cat. Long. Col. Brit. 

 Mus. p. 164. — Apparently common in Chontales. Also 

 Guatemala. It is liable to be confounded with the Mexi- 

 can C. melancholicum* 



Callichroma columhinum, Guer. Revue Zoologique, 1 838, 

 p. 282. — Found also in Cuba. 



Coremia Mrtipes, Oliv. Entom. IV. QS, p. 14, pi. 1, f. 

 8. — This common South American species is met with of 

 large size in Chontales. 



Cyllene guttatus, Chevrolat, Ann. Soc. Ent. Fr. 1860, 

 p. 459. — Apparently common in Chontales ; also Mexico. 



Cyllene Cayennensis, Laporte and Gory, Monogr. Clytr. 

 p. 10, pi. 3, f. 9. — The Chontales form has precisely the 

 same markings as the Cayenne species. 



Neoclytus Ion, Chevrolat, Ann. S. E. F., 1860, p. 496, 

 pi. 9, f. 9. — Differs from the Mexican form by the pre- 

 sence of a short yellow streak on the shoulders of the 

 elytra. Having only one example before me, it cannot 

 be decided whether the character is constant, and of 

 specific importance. 



Neoclytus Lehasii, Chevrolat, Ann. S. E. F., 1861, 

 p. 381. — One example. Although agreeing pretty well 



* This species has never been described : — Callichroma melanchoUcum 

 (Chevr., MSS.). — Stntura C. cyanomelanos sed toto nigro-velutino, opaco ; 

 tuberibus antenniferis obtiisissimis, subtiliter crebre punctulatis ; tibiis 

 posticis a basi compresso-dilatatjs flexuosis ; femoribus aterrimis, nitidie. 



Long. 15 lin.
