 proached, one 2 observed (on May lOth) sunning herself on a rock and 

 assembling the males. Larvae and pupae apparently belonging to the 

 same species found in abundance on the submerged stones." The male 

 taken by Mr. Andrewes is labelled as having been found " settled on 

 clothes " in January. Dr. Imms informs me that Pseplienoides differs

 unpaired group of retractile anal gills" and the latter "tufts of 

 abdominal gills " (=branchial filaments of Leconte and Horn). 



The 2 of P. yaliaai is taken as the type.
