538 TERTIARY INSECTS OF NORTH AMERICA. 



I Iiave examined ; the punctures of the striae are about as far apart as two- 

 thirds the width of the interspaces ; the latter are 0.25"™ wide and are barely 

 convex, slightly rugulose, and so far as I can determine not at all punctulate ; 

 the length of the fragment of one elytron is 10.5°"", the width of the same 

 elytron, 4.25'""'.
