"Taken by M. Moffat, Esq., Livingstone's Mission, and given 

 to me " (iJ. "C). 



New to the general Museum series ; unfortunately it has lost 

 its abdomen. 



Among the Pierince, Mr. Crawsliay'a collection contains several 

 rare and interesting species.

" Chrome-yellow underwing White " (R. 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 veiulet ; a diffused black 

 streak in the cell above the median vein, tlie outer border acutely 

 quinque-deutate ; 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 ifc 

 more nearly resembles the typical female than the typical male 

 does, while Miss 81iarpo's M.jacksnni more nearly corresponds 

 witii typical male M. narcissus. Unless we have here three very 

 closely allied species, it nnist bo assmnod that Jif. narcissus is 

 dimorphic ; a better series will doubtless solve the problem. 



71. Mylothris obawshayi, sp. n. (Plate VI. fig. 4.) 



A very perfect copy, in both sexes, of Phrissura lasti, and there- 

 fore intermediate in character between Af. narcissus and M. tnmeni : 

 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 witli 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.
