cell. Secondaries dark orange-yellow, bordered from the apex to the 
anal angle and thence along the inner margin to the base with 
bright pink; a large central round fawn-coloured ocellus broadly 
edged with black. The underside uniform pale pinkish brown. 
Head and thorax orange-yellow ; collar and underside of the thorax

This species is allied to B. pygmea, Maassen, from which it is 
at once distinguished by not having the black band across the pri- 
maries and the absence of the white dot at the end of the cell, 
and difference in the colour of the antenne. 
LASIOCAMPIDE. 
STIBOLEPIS SYLVIA, sp. nN. 
Primaries silvery white, brownish black along the costal margin, 
the apex, and outer margin; the veins from the cell to the onter 
margin dusky. Secondaries silvery white, with the apex and outer 
margin narrowly edged with brownish black ; the veins a short way 
up from the margin dusky. . Underside as above, excepting that the 
primaries have less black at the apex. Head and thorax yellowish 
white. Abdomen dark yellow; antenne black; legs yellow.

CHRYSOPOLOMA CITRINA, Sp.n. (Plate XXXVIII. fig. 4.) 
Primaries pale yellow, crossed about the middle, from the costal 
to the inner margin, by a band of very small brown spots, beyond 
which is a second band, extending from the apex to the inner margin ; 
the second band is very much wider, and near the inner margin 
it has several whitish spots; a submarginal row of minute dots 
extending from the apex to the anal angle. Secondaries pale yellow,
