Miss E. M. Sharpe on 
affording help to others in their studies than in pursuing my 
own work. For example, on returning home now from my 
holiday I find a large box full of letters and parcels from natu- 
ralists of Great Britain and many countries of Europe, and to 
answer all these letters and determine the specimens on which 
my opinion is wanted seems impossible. Collections mean- 
while made by me ten and fifteen years ago as well as in 
more recent years remain almost untouched, and hence also 
MS. names and greatest neglect with respect to public collec- 
tions referred to me for determination.

ance. 
Secondly , to be assured that if any letter addressed to me 
remains unanswered, it is not from discourtesy, but from sheer 
inability to find time to reply to it.

yellow on the hind wing. There is a row of unequal yellow 
spots on the hind marginal border extending to the submedian 
nervure. The base of the hind wing is deep brown. 
The fore wing has a moderately large yellowish spot in 
the middle of the discoidal cell, with a second larger oval 
spot between the first and second median nervules. 
Between the radial or discoidal nervules there are two 
medium-sized yellowish spots near the apical portion. At 
the apex of the fore wing there is a row of small white spots 
extending to the hind margin, with four smaller white spots 
outside the first row of spots, placed about the middle of the
