Mr. Kirby has given the term Syrichtus as a 

 generic name, to inckide those insects allied to this 

 very remarkable form. The genus Heteronychus, 

 De Jean, (of which I possess a species named Het. 

 Licas, from Professor Klug of Berlin) in its general 

 appearance seems evidently distinct. 



To this genus the following species may be added, 

 viz. G. Aries, Fab. as well as a new undescribed 

 species from the island of Mauritius, which may, 

 therefore, be named from that locality Mauritianus. 



Genus. Pentodon, Kirby. 

 Type of the Genus. Geotrupes punctatus, P\ib. 



Caput trigonum tuberculatum. 

 Mandibulce valida^ o-lobatae, lobis latis obtuso- 

 rotundatis, externe hirsutse, interne lanuginoste.
