IOWA ACADEMY OF SCIENCES. 
Specimens are at hand from South Carolina, Georgia, 
Florida, Alabama, Mississippi, Louisiana, Texas, California, 
and Mexico, and it was described from Cuba. 
Signoret’s description is very good, and fits our species 
in every particular except that he gives the length as 
3 mm.; this would be too small, but the length line on the 
plate is fully 4 mm., which would fit the males of this 
species, and they also more often possess the “three white 
points at the apex,’ 7 which he describes.
