Lyterius, Schon., is omitted as a doubtful member of this group. 

 Lyterius, Lac, is probably not identical with Schonherr's genus 

 (see Gen. vii. p. 250). Emjiycterus (from Asia Minor), unknown 

 to me, is placed by Schonherr in Cossoninse. It is possible that 

 Tithene {mite, p. 25) may have affinity with this "groupe."

There are a number of intermediate (and undescribed) species 

 allied to SpTienocorynus and Megaproctus, which it is almost im- 

 possible to distribute into well-limited genera, but which cannot 

 be united without also merging the two above mentioned into one 

 genus with them. Por those in my collection belonging to 

 Lacordaire's " groupe Sphenocorynides," which has the pygidium 

 horizontal (or a little deflexed), including the species in question,
