This is a genus of about forty described species, widely distributed in the warmer 
parts of the eastern hemisphere, but nearly or quite wanting in South America, although 
North America and the Antilles possess several peculiar species. Six species are here 
recorded from Mexico and Central America, three of which appear to be peculiar to the 
region, while the other three are intrusions from the North-American and West-Indian 
regions.
