It gives me pleasure to dedicate this elegant species to Dr. Thomas 

 B. Wilson, to whom this Society is indebted for placing in its posses- 

 sion one of the finest collections of Cuban Hymenoptera extant.

 I have not seen any specimens of this insect, but Prof. Poey informs 

 me that he collected, about twenty years since, both £ and 9 , and sent 

 them to Mr. Guerin, who has described and figured them. Prof. Poey 

 says: "I have seen the 9 come out of a hole pierced in an earthy wall; 

 the % has taken the 9 upon the margin of the hole ; I have seen the 

 coitus from the commencement to the end."

 The three specimens before me answer exactly to Mr. Smith's de- 

 scription of M. nitida (from Jamaica), except that the abdomen is 

 beautifully iridescent, and the length is 7 5- — 8 lines, instead of 5 — 5']
