“Taken by M. Moffat, Esq., Livingstone’s Mission, and given 
to me” (R. C.). 
New to the general Museum series ; unfortunately it has lost 
its abdomen. 
Among the Pierine, Mr. Crawshay’s collection contains several 
rare and interesting species.

* Chrome-yellow underwing White” (2. C.). 
The form now received differs from the typical male from 
Kilima-njaro in having the costal black border continuous, only 
interrupted by the upper discocellular veinlet ; a diffused black 
streak in the cell above the median vein, the outer border acutely 
quinque-dentate ; and sometimes a little oblique black streak below 
the submedian nervure and a broad apical black bar uniting the 
first two marginal spots of the secondaries: in some respects it 
more nearly resembles the typical female than the typical male 
does, while Miss Sharpe’s M. jacksoni more nearly corresponds 
with typical male MW. narcissus. Unless we have here three very 
closely allied species, it must be assumed that MZ. narcissus is 
dimorphic ; a better series will doubtless solve the problem. 
71. Mytoruris CRAWSHAYI, sp.n. (Plate VI. fig. 4.) 
A very perfect copy, in both sexes, of Phrissura lasti, and there- 
fore intermediate in character between MW. nareissus and M.triment: 
in size, form, and colouring the male resembles the latter, but the 
apical patch extends in an oblique curve from just beyond the 
cell to the third median branch, its inner edge being zigzag, the 
remaining marginal spots not included in this patch are hastate ; 
the base of the wings is slightly more heavily blackened than in 
M. trimeni and the marginal spots of the secondaries reduced to 
mere points ; on the under surface the apex of primaries and entire 
surface of secondaries are bright lemon-yellow instead of saffron- 
yellow. Expanse of wings 57-64 millim. 
The female has pearl-white primaries, the cell, costal border, and 
base of internal border densely dusted with smoky grey; an 
oblong patch of the same colour at external angle; the apical area 
and outer border to below the first median branch smoky grey,
