11. Odontocera fasciata. 



Necydalis fasciata, Oliv. Ent. No. 74, p. 10, pi. i. f. 0. 



Odontocera chrysozone, White, Cat. Longic. Brit. Mus. 

 p. 192, pi. V. f. 5. 



White gives the reference to Olivier's figure with a 

 mark of doubt; but on comparing the description as 

 well as the figure, there can be no uncertainty about 

 his species being the same. 



It is generally distributed throughout the Amazons, 

 and not uncommon in the dry season, at sweet-smelling 

 flowers. Like all the other species of' these beautifully 

 varied and interesting little creatures, it flies nimbly from 

 flower to flower, deceiving the eye of the beholder by 

 its strong resemblance to a wasp.
