Tab.\xus xeogermaxic'us Kicardo.

The determination of the above synonymy is based on the comparison by one 

 of us (G.F.H.) of specimens identified by jMiss Kicardo as T. neogermatiicus 

 Kic. with Taylor's types. Taylor has placed his species in two different groujis, 

 fiifjilivtis in Group ix. and liilli in Group x., but the distinction between these two 

 gi'oups is often a matter of aljrasion and the groups are not natural ones, in any 

 case, from the description, liilli would appear to be wrongly placed in Group x., 

 as the segmentations are described as greyish. A comparison of the two descrip- 

 tions reveals no difference apart from differences in what might be described as 

 shades of colour. The determination in regard to fitgitivus was checked by the 

 examination liy both of us of a paratype whicli is absolutely identical with the 

 specimens determined l)y Miss Ricardo.

This species li;is been misidentitted in Australian collections. Specimens of 

 T. australis sent to London (G.F.H.) have been detei-mined by Dr. G. A. K. 

 Marshall and Mr. E. E. Austen as T. brevior Walker. Examination of a short 

 series of specimens of T. australis and T. criipsert/thrus, including specimens 

 identified by Taylor, showed that the species were identical. Tlie types of Tay- 

 lor's two species have also been compared (G.F.H.).

The name of this s]:)ecies l)eing' preoccupied by an Indian species — T. palpuUs 

 Eicardo (Records Indian Museum, iv.. No. vi., 1911, p. 212) — we propcse the 

 ahove to replace it. The name T. milsoni Taylor, is also preoccupied by 7'. mil- 

 soiiix Ricardo, but in this instance we understand that the name has already liecn 

 altered by Jlr. Taylor.

Comparisons of s]iecimens of T. daplweiiKs Taylor with the descriptions of T. 

 nigrimanuK Walk., and T. hatlhts Summers, leaves no doubt in our minds that 

 Taylor's species is the same as Walker's. We have thought it lietter. however, to
