1922] Forbes: Wing-Venation of Coleoptera 343 



The Cleridas are possibly related to the Ostomidae. 



The Lymexylonidae are not especially generalized, and suggest 

 the point of origin of the Heteromera. 



The Heteromera show no sign of double origin where now 

 divided; the Meloid£e on the other hand, contrast strongly with 

 the families associated with them, apparently resembling the 

 Rhipiphoridae and Stylopidae. 



The Clavicornia are a heterogeneous group, on which light 

 will certainly be thrown by the venation and folding.
