OF NORTH AMERICA. 159 



This genus was described by Clemens under the name of Pcecilop- 

 iera, for which Grote substituted (E/a, the former being preoccupied. 

 It contains but one American species in which the prevailing colors 

 are black and yellow. The genus though referred above to the Zygce- 

 ntncE, has many points of resemblance to the Lithosiidcc, and lies in 

 the debateable ground between the two groups.
