Several of the genera in this family hardly belong to it, but 

 they are represented by very few species, and may be considered as 

 abnormal genera and not as the types of new families. Foerster 

 considers Caratomus to belong to this family and not to the Peri- 

 lampidae, with which it has been previously placed. He remarks the 

 resemblance of Dipara to some of the Myrmaridge, and suggests the 

 identity of his genus Hypsicamara with Euneura. The name 

 Cyrtogaster is changed by him to Dicormus, Psilocera to Dichelysis, 

 and Prosodes to Cryptoprymna, and he mentions the affinity of 

 Panstenon to the Cleonymidas. Asaphes (changed by him to 

 Isocratus) is one of the abnornal genera of the family. Curyna he 

 alters to Pachycrepis.
