HETERONEMINAE 



We here find a series of American genera, part assigned to the 

 Bacunculinae, part to the Phibalosominae by Brunner and Red- 

 tenbacher, based on characters which as used are wholly or in 

 part unsatisfactory. The proportionate length of the median seg- 

 ment is by far the most important of these; being decidedly shorter 

 than one-third of the metanotum {Dyme, Calynda), distinctly 

 shorter than the metanotum (Bostra) or longer than the metano- 

 tum (Bacteria, Otocrania). Separation of Calynda from Dyme is 

 made on the greatly produced operculum in females of that genus; 

 but in females which are assigned to Bostra, similar contrasts in 

 this organ are found. Separation of Otocrania from Bacteria is 

 made bj^ the two very large horns on the head, but again there 

 are species which show this feature in every way similar, but 

 from the proportions of the median segment are referred to 

 Bostra. It is probable that the majority pr all of these genera are 

 valid and that additional valid genera are represented among the 

 already described species concerned; but we are convinced that 

 the generic assignment of the species is and will be in many cases 

 inaccurate, until the genera involved are carefully studied and 

 other or additional characters determined for their separation. 

 At present far too little material is at hand to attempt this study 

 and we are obliged to follow Brunner and "Redtenbacher. 



It is indeed deplorable that, with so many species before them, 

 those authors have made virtually no effort to study and discuss 

 these problems in a scholarly and scientific manner. They have 

 treated the forms recorded or described throughout the" Insekten- 

 familie der Phasmiden" practi(!ally without regard for any recent 

 scientific literature, and in a brief , stereotyped and careless manner 

 that would have brought little credit to an author publishing one 

 hundred years earlier. In their work palpably careless inaccuracies 

 in geographic records are frequent, and localities given for many
