The throe species of the i/tis type which we know from Mount Goliath are 

 especially interesting. One of them (see below, No. 3) comes near a species from 

 the Arfak Mountains {bakcri); another represents iltis from the Owen Stanley 

 range (see below, No. 1); and the third (see below, No. 2) has a very distant 

 ally in botkwelli from the Arfak Monntains. 



Mr. A. S. Meek is much to be congratulated on having at last successfully 

 accomplished a task on which we had mutually agreed nearly ten years ago. 



We hope to figure the new species in next year's volume of Novitafets 

 Zooloyicae. 



a. A red discal line on the underside of the hindwing (Nos. 1 — G). 



1. Delias callista spec. nov. 



(??. Alis posticis area centrali paginae inferioris aurantiaca {<S) vel Inteo-

The sexes are remarkably different. 



[?. Upperside white. The black costal border of the forewing does not enter 

 the cell ; the discocellnlars are black, but this bar is a mere line, being very much 

 thinner than in D. iltis ; the black outer border does not quite extend down to the 

 subcostal fork and is a little wider below the centre of the wing than in D. iltis. 

 There are two small white subapical dots. The black border of the hindwing is very 

 thin, being restricted to the fringe and the extreme edge of the wing and slightly 

 widened at the veins. 



The underside of the forewing is white. The discocellular bar is broad and 

 triangular, but less broad than in D. iltis. Before the apex there is a curved row 

 of three orange spots, the row being continued along the distal margin by some 



minute dots. The hindwing has the black markings almost exactly as in D. iltis, 



bnt the central area and the submarginal spots are of a beautiful orange colour. The 

 central area has a somewhat diffuse white border, between which and the black 

 stripe there is a red border proximally in the cell and below it ; the portion of the 

 central area which lies in front of the cell is costally pointed and externally incurved, 

 being much smaller than in I), iltis on account of the greater development of the 

 black, the black lines being broadly united at the costal margin ; a small ovate 

 discocellular spot is white. The black discal line is produced outward at the veins, 

 the red line following it being Innate. This red line is outwardly bordered by white 

 Innules, upon which follow the orange submarginal spots, which are larger than 

 the corresponding (white") spots of IK iltis; as a rnle these spots are more or less 

 reddish at the white lunules. The black border of the wing is thinner than in 

 D. iltis. 



? . There are two colour-varieties of this sex ; in the one the ground-colour of 

 both wings above and of the forewing beneath is white, while the forewing is yellow 

 in the other above and beneath, the upperside of the hindwing being anteriorly also 

 more or less yellow. The two forms are otherwise alike. 



Uppei-side : the black border of the forewing enters the apex of the cell, the 

 black (liscocelliilar b ir bein;; completely united with it, some specimens bearing a 

 small white spot below the costal marg'n as an indication of the interspace existing 

 in the J l)etween the bar and the band ; the marginal band is 6 mm. wide at the
