have a spot-like brown shading, and a similar shading is seen 

 on the conspicuously curved axillary vein. The description 

 of the wings is taken from Schiner's excellent description. 

 In Walker's type an extra brown spot is present on the vein 

 dividing the second and third posterior cells, and a faint one 

 is discernible on the apex of fifth longitudinal vein : these are 

 not present or are very faint on the other specimens. The 

 fourth posterior cell is much narrowed, but open at border, in 

 this species.

Type ( <$ ) and another male from Australia ( Children Coll.), 

 and a female from S.E. Tasmania (E. D. Atkinson). 



This species is nearly allied to Peleeorhy nchus maculipennis, 

 Macq., but distinguished by the white tomentose bands on the 

 second, third, and fourth segments of abdomen being interrupted 

 in the middle and by the presence on the thorax of two striking 

 elongated white spots, each situated on a black stripe which 

 reaches the whole length of the greyish-brown thorax. In 

 the male the hairs on the face are black and thick. Beard 

 yellowish. In male and female the hairs at sides of thorax 

 are black, reddish at base of wings. Markings of wings very 

 similar to those of P. maadipennis, but the median band of 

 brown spots is narrower, and the two spots on the second and 

 third veins are widely separated, that on the second vein 

 being nearer base of vein, below the half length of vein ; the 

 apex of wing is brownish, so that the apical spots are not 

 distinct. 



Length of type and other specimens varies from 15-20 mm.

Type ( S ) from New South Wales ; type (?) from Dar- 

 denong Ranges, Victoria {French Coll.) ; ? from Tasmania 

 (M. AUport) ; a £ in Mr. French's collection from Victoria. 



These specimens, which I at first took to be Macquarl's 

 species before seeing the type, have not been describe I 

 before. 



They are nearly related to P. maadipennis, but are distin- 

 guished from it by the deep blackish-brown markings on 

 wings, which are also larger. The base of wings is more 

 widely dark, extending to the posterior border and joined by
