NEW THYBIDIDAE IN THE TRING MUSEUM. 



By W. WARREN, M.A., F.E.S. 



1. Addaea castaneata spec. nov. 



Forewing : with basal area, a broad mediau fascia, aud the whole marginal 

 area deep chestnut-brown, with slightl}' darker transverse striae especially 

 along costa ; a violet purplish tinge along snbmedian interspace; the meJiau 

 fascia is slightly oblique, narrow at costa, swollen a little above the mediau vein 

 and bulged below it ; on each side of it is a whitish obliipie band, the inner one 

 narrow and the outer wide, with some grey strigae in their centre ; fringe brown, 

 blackish at apex and anal angle. 



Hindwimi : similar; in the marginal brown area there appears a narrow 

 submarginal band, wliich is slightly visible on forewing as well ; iViugo blackish 

 towards apex only. 



Underside similar, the contrast greater between the pale and dark areas. 



Head, thorax, and abdomen all brown. 



Ex])anse of wings : 2U mm. 



2 6S from Milne Bay, British New Guinea, January and February 1890 

 (Meek). 



Allied to both polyphoralis Wlk. and piisilla Butler, but entirely distinct from 

 either. 



2. Banisia angustifascia Warr. 

 In yoc. Zool. vi. p. 315 (IS'j'jj I suggested that my B. angustifascia ? from 

 Amboina was the same species as B. maltifenestrata 6 Warr. from Humboldt 

 Bay, New Guinea. This identification was prcmatnre. For though angustifascia 

 occurs commonly in New Guinea, also in the Kei Islands and the Louisiades, yet 

 a good series of both sexes shows that its real c? is much more like the ¥ than 

 nudtifenestrata. The sexes agree in having the apical area of forewing filled np 

 with dai'k fuscous, a-i in Pagenstecher's nitida; but in place of the numeraus 

 whitish hyaline spaces which a[)pear in midlife nestrata, the S of anqasti fascia has 

 normally f)ur square white sjjats iu forewing aud two in the hindwiug ; the two 

 most prominent are placed, in the forewing, one above the other on each side of 

 vein 2 between the two branches of the postmedian fascia, the other two being on 

 the iunerside of the inner branch, but the upper one of the latter pair is very 

 small and often obsolete ; in the hindwiug the two spots are always above vein 2, 

 one on each side of the inner branch of fascia. In multifenestrata <S the apex of 

 forewing is of the ground colour, and there are some irregular black spots before 

 outer margin above the middle ; at present no ? of this form has appeared, though 

 an additional S from the Kumusi River has been sent, exactly like the original 

 2 (?(? from Humboldt Bay. 



3. Banisia funesta spec nov. 

 Forewing : glossy Idackish fuscous with a slight olive tinge ; the bands, 

 which are slightly darker than the rest of wing, are placed almost exactly as in 

 B. angustifascia Warr.
