tlic male prove to be concomitant with the deutate calcar of 

 the female, these will prove most useful characters. I was 

 unable to examine the females of the Britisih JNIuseum species, 

 from lack of time. 



I have taken stylopized specimens of P. eboracina,ixn\ have 

 P. turncriuna thus atfectcd. 



Palteorhiza muiri, sp. n. 



Very closely allied (c?) to P. perviridis cassice, Cock., but 

 very different in superficial appearance, of a much duller or 

 darker green, changing to purple in different aspects. The 

 wings are rather darker. Tlie cly[)eal marking consists of a 

 large triangular cream-coloured spot, not prolonged back- 

 wards behind the middle, two minute dots above tlie antenna? 

 being sometimes also present ; lateral pale markings narrower 

 and only prolonged a little above the antennae ; no prothoraeic 

 spots. Puneturation of thorax and abdomen decidedly closer 

 and slightly finer. Agrees with perviridis in the angulation 

 of the margin of the second ventral segment, the lateral earinte 

 of the third and fourth ventral segments, the general vestiture 

 of the segments beneath (but the hairs are black), and for the 

 most part in the genitalia and hidden seventh and eighth 

 ventral segments. As in so many of the Australian Prosopidae, 

 the position of the recurrent uervures varies in individuals.

Hab. Amboina (Muir). 



Palceorhiza varicolor var. eboracina, Cockerell. 



I found this form, described on a single specimen, very 

 commonly on various flowers during July at Cairns and also 

 at Kurauda. As 1 have not received it from Dodd, nor was 

 it collected in the Cairns district by Turner, I suppose it is 

 in season during the cold months of the year, when collecting 

 is considered poor in the district. Both sexes are extremely 

 constant in the facial markings, and superficially quite unlike 

 any varicolor that I possess. I have, further, seen no 

 P. varicolor resembling the original type, and those that 

 I myself took in the Cairns district are very constant, none 

 resembling the original type, and still less are they like 

 eboracina. 



Prosopis, Fabr. 



Australia is extremely rich in described species of Prosopis, 

 and doubtless but a fraction of the existing species have been
