the wliite of the inner area, rerluoing the black of outer area to four wedge- 

 shaped black 2)atches ; the three white marginal spots above vein 5 run in 

 only half across the black area, forming three white streaks. 



On the hindwng all the seven white marginal spots run into and join the 

 white discal area, reducing the black outer area to seven black wedge-shaped 

 patches. Abdomen yellow. 



Habitat. Tenasserim to Perak. 



Our next species is hornochroa Griinb. 



Melanothrix hornochroa Griinb. 



Melanothrix hornochroa Griiiiberg, Entom. Rdsch. 31 p. 21 (1914) (Kina Balu). 



Dr. Griinberg in Seitz figures the $ of this insect as the 9 of nicevillei., while 

 he refers to it under his original description of his llehnothrix nicevillei ab. radiata, 

 as being intermediate between typical ? nicevillei and his ab. radiata (his typical 

 nicevillei being the $ of lencotrigona) . 



$ differs from the ?? of nicevillei and lencotrigona in being as a rule larger, 

 in the black outer area being wider, and in the black on the inner area of the 

 forewings being much extended. It differs also from both in the white on both 

 wings being much purer, and is intermediate between these two species in that 

 the white marginal spots do not join the inner white areas of both wings. ))ut 

 are not nearly so widely separated from them as in lencotrigona . 



Habitat. Kina Bahi, Borneo, 1 (?, 5 ??. 



We now come to radiata Griinb. 



Melanothrix radiata Griinb. 



Melanothrix nicevillei var. radiata Griinberg, Entom. Rdsch. 31. p. 21 (1914) (Kina Balu). 



This insect differs at a glance from $ of nicevillei in having the white replaced 

 by huffish cream-colour, and in the black of the outer area being much wider, 

 on the forewing at least one-third wider, and on the hindwing it takes up fully 

 the outer half of the wing. The black is also more bro\\iiish. All the marginal 

 spots join the inner cream area of both wings so that the black of the outer areas 

 is in the form of seven large wedge-shaped patches on each wing. 



Habitat. Kina Balu, Borneo, 3 ??. 



The (J of this and the following are unknown. 



Melanothrix lativitta Griinb. 



Melanothrix lativittata Giiinherg, Entom. Rdsch. .31. p. 21 (1914) (Kina Balu). 



This species calls for no special remark. 

 Habitat. Kina Bahi, 1 ?. 



V\'e now come to Semper's Melanothrix pulchricolor from Mindanao. This 

 is evidently a cj^uite distinct species and I describe it below. 



Melanothrix semperi sp. nov. 



?. Wings similar to nytnphaliaria, but less black. Abdomen yel]o\\ with 

 black transverse bands. 



Habitat. East Mindanao, Philippine Islands. 

 Our next species is alternans Pagenst.
