T. Phrissosceles rufidorsata. 



Perixera rufidorsata Warr. Nov. ZooL. III. p. 312. Kbasias. 



Perixera rii/annidaria Warr. Nov. ZooL. IV. p. 221. Apia, Upoln. 



This species must be transferred to Phrissosceles. The cell-spot of the 

 hiudwiugs is variable ; besides the large smok)' black form with paler centre and 

 the ronnd white dark-edged form, there occur large round spots filled up with 

 ochreous and smaller spots with dark edges ; the red-tinged dorsum will always, 

 however, distinguish the species. In the original description of rufidorsata an error 

 occurs with regard to the marginal spots ; the larger spots are between the vein ends, 

 the smaller at the ends. The species subsequently described from Apia as riiJ'nnnK- 

 laria cannot be looked u])on as distinct, when the variability of the cell-marks is 

 taken into consideration. Besides Apia, it occurs in Tugela, Solomon Islands ; 

 Milne Bay, New Guinea ; Laiwni, Obi ; and Woodlark Island. 



8. Pisoraca variospila sp. nov. 



I propose this name for the insect hitherto, I think, wrongly identified in the 

 British Museum Collection as monetar'ia Guen., and so called by Hampson in 

 the Fauna of British India, Moths, Vol. III. p. 450. 



Gnen^e's short description of monetaria runs : " Ailes a peine dentees, d'un 

 rouge-testae^ clair, sans atomes, points, ni dessins autres qu'nne large tache 

 cellulaire d'un blanc d'argent cerclee de gris au.x ailes inferieures. Dessous d'un 

 carn6-rose clair, avec cette tache en transparence. Front et palpes concolores, a 

 vertex blanc. C'uisses post^rieures garnies int^rieurement de poils cotonneux. 

 Borneo. 1 cj. 36 mm." 



The last sentence cannot certainly refer to Pisoraca, in which the hindlegs of 

 the c? are armed only with three spurs, but in which genus the Indian insect is 

 rightly placed by Hampson. Before I observed the discrepancy between this insect 

 and Guenee's account, I had described (Nov. Zool. IV^ p. 304, 1897) a Perixera? 

 pleniiinia from a ? from Penang. This is manifestly identical with Gueniie's species, 

 agreeing in every particular. I have seen another specimen, also a ?, from the 

 island of iSaparoea, but at present no 3 S. 



The true monetaria probably does not occur in India at all. What evidently 

 led to the misidentification is the fact that one of the forms of the Indian insect has 

 a round white dark-edged cell-spot in the hindwings, like monetaria, instead of the 

 more usual cloudy black one with pale centre. The description given of it by 

 Hampson {loc. cit.) renders re-description unnecessary. The ground colour is always 

 yellowish ochreous, with the usual markings fairly well expressed ; monetaria Guen., 

 on the other hand, is dull reddish without markings. 



9. Ptychopoda delicatula sj). nov. 



Forewings: semi-transparent bone-colour, tinged towards base with greyish 

 ochreous ; the lines greyish ochreous ; first curved, very obscure ; second, in middle, 

 sinuous, the small black cell-spot on its outer edge ; third at two-thirds, fine, 

 lunulate ; submarginal pale, preceded by an ochreous grey shade, which forms a 

 deep sinus beyond cell, and a less conspicuous one above inner margin ; fringe 

 bone-colonr, with minute dark dots at base beyond the veins. 



Hindwings : similar, without first line.
