74 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," which he describes.
