M. E. Penis, in his admirable Essay on the insects which

 the metamorphoses both of this species* and of H. flexuosus,

 differences which exist, especially in the larvae of the two 

 species, in the number and disposition of the ocelli, the 

 structure of the maxillae, mentum and mandibles, and the 

 conformation of the terminal abdominal segment; discre- 

 pancies, he remarks, to which we are unaccustomed in larvae 

 of the same genus, and which give rise to grave doubts as to 

 the propriety of so intimate an association of the two species.
