[Bead 12th May, 1921] 



The following paper contains the descriptions of a few species 

 that have been discovered within recent years. Most of the new 

 species belong to the genus Scleroriniis ; the members of this 

 genus are often exceedingly difficult of identification, as many, 

 particularly those belonging to Section 1., run extremely close 

 to each other, and a knowledge of both sexes is absolutely 

 essential in many cases for identification. For this reason 

 several species represented in my collection by the female sex 

 only are left undescribed. 



Within the last two years the veteran entomologist, Dr. David 

 Sharp, has turned his attention to the Amycterides, and is now 

 working on the subdivision of the larger groups, such as 

 Phalidura, Talanrinns and Scleroriniis, into smaller genera, 

 according to the structure of the male genitalia. One paper 

 has already been published (Entomologists' Monthly Magazine, 

 third series, vol. vi., Jan., 1920, pp. 1-7) dealing with the 

 genera constituting what Dr. Sharp characterises as the tribe 

 Phalad urines. This tribe contains the old genus, Phalidura 

 (Psalidiira), subdivided by Dr. Sharp into Phalidura and 

 Aphalidura, a new genus — Prophalidura — of which Talaurinus 

 riverinae is the type, and Eustatius, formed for a new species 

 E. fergusoni. A table is given of the relation to each other of 

 these four genera. As the change of names affects many Vic- 

 torian species a few comments may not be out of place. 



Phalidura. Genotype — P. reticulata, Boisd. {= P. mirabilis 

 (Macleay) Fischer, nee Kirby). In the name of this genus 

 Dr. Sharp has revived the original and certainly correct spell- 

 ing in preference to the emendation Psalidura made by Erickson 

 (Agassiz Nomencl. Zool. Col., p. 136), and not by Gemminger 

 and Harold, as stated by Dr. Sharp. In this revival of the 

 name PJialidura I am absolutely in accord with Dr. Sharp. 

 Under the genus as defined by Dr. Sharp are included groups
