Cho^ada callicrossa. 



Boarmia callicrossa Meyr., Tr. E. S. 1889. p. 498. 



Meyrick described this species from a pair, very dissimilar, from Port Moresby, 

 New Guinea. In the series from Key Island there are five ? ? and fourteen cJc?, and 

 it is evident at once that the species is a very variable one. All five ? ? are white, 

 witli greyisli ochreous tints ; eight c?(? agree with this form, but are rather more 

 strongly and darkly marked. This, at least in Key Island, is the common form. 

 Of the remaining six 6 S, two have the irmer half of forewings and costal half or 

 third of hindwings suffused with rufons grey ; two others have the fawn-coloured 

 fasciae largely developed; while the fifth and sixth answer to the original description 

 of Meyrick, inasmuch as one has the central fascia closely filled with black and grey 

 scales, as in Meyrick's <?, while the other is wholly sufl'used with rufons, lilce 

 his ? ; but the deep black borders to the subterminal line, which in his c? occur in 

 the unsuffnsed form, are in this instance united with the suffused form, rendering it 

 stOl more unlike any of the others. Taking Meyrick's irroratcd <S form, as we must 

 do, as the type, his ? form, which is evidently not merely sexual, may be distinguished 

 as ab. sufPasa ; that with the partial suffusion, us particolor ; that with the broad 

 fawn-coloured submarginal band, as colorata; while the more ordinary white form 

 may be known as ab. simplex. The intensification of the black edges to the 

 submarginal line may possibly occur at times in each of the other forms. There is 

 one peculiarity by which the cf c? may be at once recognised. The fovea at base of 

 forewings appears as a very minute eye, the circular base of the fovea being ringed 

 with black scales, while in the centre of the summit is a smaller black ring of scales, 

 with a minute central pale poiut. 



Xylinophylla gen. uov. 



Fareivings : triangular ; costa straight, but strongly convex before ape.x ; apex 

 bluntly rounded, subfalcate ; hindmargin irregular ; a blunt elbow in middle, 

 with two sinuses above, oblique and subcrenulate below ; inner margin sinuous, 

 the anal angle lobed ; no fovea. 



Hindidngs : with costa slightly shouldered at base, truncate at aj)ex ; a 

 blunt tooth at vein 7, and a stronger one at vein 4 ; thence straight and sub- 

 crenulate to anal angle. 



Antennae of c? quite simple ; palpi upcnrved in front of face, short and stout, 

 terminal joint small, button-shaped ; tongue and frenulum present ; hindtibiae 

 thickened, with a pencil of hairs in groove and four spurs. 



Neuration: forewings, cell barely half as long as wing ; discocellnlar vertical, 

 slightly curved ; first median nervule at three-fourths, second close before end of 

 cell; radials normal: 7, 8, '.», stalked from close before end of cell; 10 free; 11 out of 

 12. Hindwings with first subcostal and second median from just before angle of cell. 



Type : Xylinophylla ochrea sp. uov. 



Nearest to Gonodontis Hiib., from which it is distiugnished by the sinii)le 

 antennae of the i and by the different neuration. 



Xylinophylla ochrea ^\ nov. 



Forewings: whitish ochreous, with sparse and coarse brown-black dusting; 

 base of costa brownish: first line fine, at one-third of costa, where it is marked by a
