* This species (which is remarkable for its close resemblance to 0. macule 

 pennis, Smith) is ticketed 0. bifasciatus, Westw., which appears to be the name 

 which Prof. Westwood originally intended for it, as it has been allowed to 

 stand in Thes. Ent. Oxon. p. 119 under the description of 0. batesianus.
