Several specimens were collected on the Mount Gay estate, 

 August 26, at the roots of grass on muddy soil adjacent to pools 

 of water, and September 6, at an altitude of 50 feet, on grass and 

 weeds growing out of a pool of water ; also on the Telescope 

 estate, and at Balthazar, March 5, on the open sandy shore of a 

 stream, under decaying leaves.

Several specimens of different sizes and more than one pattern 

 of marking were found at Balthazar, Windsor, and on the Mount 

 Gay estate. They were found mostly in March and April, at 

 which time they were also in the larval stage, on wet mud and 

 sand near the river. Numerous specimens were observed, and 

 they were found to fly quickly when disturbed. A very small 

 specimen, with the broad yellow mark on the margin of pronotum, 

 was found, August 26, on the Mount Gay estate, at the roots of 

 gi-ass, on mud, near pools of water.
