412 Mr. Kirby's Century of Insects. 



COLEOPTERA iieteromera. 

 (Tenebrionidce.) 

 PsAMMODES Kirby. 

 Lahrum emarginatum. 

 Labium bifidum : lobis divaricatis. 

 Mandibulce apice conniventes, bidentatae. 

 Maxilla: basi apertse. 

 Palpi filiformes, maxillares elongatse. 

 Mentum trapeziforme. 



Antemia graciles, subclavatae : clava triarticulata. 

 Corpus oblongo-ovatum. 



This genus is intermediate between Pimelia and Tentyria: from 

 the former it is distinguished by its bifid labium, by its quadran- 

 gular mentum, narrowest below so as not to cover the base of the 

 maxillae, and by its long, slender, clavate antennae ; and from the 

 latter, besides these characters, by its emarginate labrum. It is 

 to be observed, that in this latter organ Pimelia muricata and his- 

 vida differ from each other, as well as in their antennae, and the 

 form of their bodies ; hence the genus might be divided into two 

 families, * Corpore subgloboso, ** Corpore oblongo.
