One example, in Mr. Belt's collection. 



Amphionycha hifasciata, Bates, Trans. Ent. Soc. 1869, 

 p. 386. — This is very closely allied to the celebrated Am- 

 phionycha Knownothing f of Thomson, which name its 

 author subsequently (1868) changed to -4. Bruryi, stating, 

 at the same time, that its habitat is Mexico. A. hifas- 

 ciata seems to differ constantly in the gray colour of its 

 elytra, and the narrow black margins to the yellow fasciae. 

 Mr. Belt has taken a large nnmber of examples.
