aud obtuse-truncate in the females; the fifth segment in the latter sex 
has on its disk above, a subtriangular depressed space, somewhat ru¬ 
gose, and clothed with short decumbent hairs which sometimes have 
a silvery reflection in certain lights. Only four species of this genus 
are at present known to me; three of these are very abundant in 
August, on flowers in the neighborhood of Philadelphia. They are 
easily captured, being very sluggish in their habits.
