apical fringe ; pygidiura elongate, narrow, its sides raised. 

 Neuration ordinary, but varying in detail as in most 

 Australian Prosopidaj, of which I have examined long series. 

 Second recurrent ncrvure sometimes received far within the 

 second cubital, as far as the first recurrent is from tlie other 

 extremity, usually only slightly within this cell, sometimes 

 interstitial with second transverse cubitus.

Obs. Not having been able to compare it with the types 

 of the many known species, I do not feel sure that this may 

 not in some of its many varieties have been already described. 

 It is very interesting from the definite character of its 

 variations. My series was taken at random from hundreds 

 of examples that were visiting the flowers of a small forest 

 tree. There were no males present and the females were all 

 engaged in brushing the pollen inwardly towards the mouth 

 with the front legs in the usual Prosopid manner. A dozen 

 specimens could be swept off at a single stroke of the net. 

 There is no noteworthy variation, except in colour and 

 details of neuration, the latter being similarly unstable in 

 many other Australian Prosopida3, so that the exact position 

 of the recurrent nervures &e. is hardly worth referring to, 

 unless one has examined a large series of examples. As 

 to the colour-variation, I find similar cases in Australian 

 Prosopis, those Avith a ferruginous abdomen having black- 

 bodied forms also, in some of the species I have taken in 

 numbers. Further, the abdomen may become conspicuously 

 metallic (blue) in the dark varieties. For this reason these 

 colour-ditl'erences are not to be taken into account for 

 purposes of specific distinction, unless they are known to be 

 constant. 



L'. variabilis must be very close to E. myrtacearum, if the 

 latter is not identical with one of its colour-variations. 

 However, in the former the first rccurentis generally, if not 

 always, received well within the second cubital cell.

Head mostly yellow, but the occiput and a wide transverse 

 band including the ocelli, which is produced downwards on 

 each side along the eyes for about half the distance between 

 the top of the eyes and the line of insertion of the antenme, 

 are black. The yellow line formed between the black occiput 

 and the black vertical band is narrow and irregular in outline.
