It is highly improbable that the fragmentary remains on which Professor Pictet 
founded this species belong to the genus Dercetis. Ihave stated that they much 
resemble those of Leptotrachelus, and have given the reasons for doing so on a 
previous page. It is unfortunate that I have not had an opportunity of examining 
the specimens themselves, and until this has been done it may be advisable to 
retain the name given by Professor Pictet.
