10 PROCEEDINGS OF THE NATIONAL MUSEUM vol. i04 



Type: In ZMB, from Pennsylvania. 



Other localities: United States: From Massachusetts to Texas. 

 Honduras: La Ceiba (one specimen). 



Remarks: Only one specimen is known from south of the border, 

 but it is quite conceivable that the species, which is known to occur 

 in Texas and which feeds on Polygonum, may extend all through 

 Central America. It is one of the group with costate elytra, more 

 apparent in the female, and is related to the Central American species 

 D. recticollis Jacoby, but is smaller and darker with pronotal spotting.
