Noctuidyc in the Joiceij Colleclion. 11 



M'ing the cell-spot is partly joined to the blank terminal 

 area. Pendino^ fuller knowledge, I propose to call this form 

 R. ohliqua philippinensis (PI. I. fig. 7). 



7. Risoba oivyarra, sp. n. (PI. T. figs. 8 J" , 9 ? •) 



— liisoba cebea, Hampson, Cat. Lep. Phal. xi. p. 435 (191 y) (part;.),

This species differs in the S fi'om kebea, B.-Bakei*, with 

 which it has hitherto been confused, in the longer palpus 

 (l^ diameter of ej'^e in kebea, twice diameter of eye in 

 owgarrd) ; in the rather smaller size (36 ram. in oivgarra, 

 40 mm. in kebea) ; in the broad white subcostal area along 

 SC-SC^ nearly to apex (in kebea the antemedial green and 

 brown shading extends broadly to middle of wing from costa 

 to hind margin! ; in the absence of the white tooth between 

 tlie apical dark patcli and the dark mark behind S(/' (which 

 in owgarra is merely a diffused purple-grey shade) ; in the 

 reduced and more oblique basal white shade, which in 

 owgarra starts from the base of SC (with narrow white line 

 before it from base of costa) and is crenulate to about two- 

 fifths hind margin, while in kebea it starts from costa and is 

 almost straight to two-fifths hind margin ; the wliite baud 

 proximally to postmedial line is less straight and regular in 

 owgarrai\^^n in /ce/;^fir, the postmedial line rather more ciirved 

 and less dentate ; the white marginal lunule behind M^ is 

 much smaller in oivgarra than in kebea. Hind wing with 

 the dark bordering reduced and almost without the black 

 postmedial spots on veins. 



In the ? there is a similar difference in size (36-38 mm. 

 in oivgarra, 44mm. in kebea); the white basal patch is 

 reduced and has the edge crenulate, as in the ^ , the type 

 ? of kebea being without any dark shading on the white 

 patch, whilst all ? ? of owgarra yet studied have all but a 

 narrow line at distal edge shaded with green marked with 

 brown ; the pale postmedial costal patch extends to a point 

 on M^ in oivgarra (in kebea it is intercepted by a violet shade 

 on R^) ; the difference in the apical patch is as in the J , but 

 the dark mark behind SC' is enlarged and very black iu 

 the ? o^ kebea ; in kebea ? the postmedial line is inw'ardly 

 oblique from R' to hind margin about 2^ mm. from ante- 

 medial line, in owgarra the two lines are about 5 mm. apart 

 on hind margin. 



The description of cebea (in Cat. Lep. Phal. xi.) seems to 

 embrace some of the salient points of each species, the ? in
