Numerous specimens of this insect were taken in various parts 

 of the island. This species varies in the size and form of the 

 black dot on the front of vertex and in the number of yellow marks 

 on the same. Occasionally the upper border of the front is also 

 slenderly yellow.

More than thii-ty specimens of this bright gi-een species are in 

 the collection from St. Vincent. This species is equally common 

 in the islands of Cuba and Trinidad ; but we have not yet seen 

 specimens of it from the mainland of South America.
