CEMIOSTOMA AGAIN—In my note ante, p. 489, I have stated that 
in the “ Transactions of the London Entomological Society” Ser. 
2, vol. 5, pp. 21 and 27, and in Ser. 3, vol. 2, p. 101, certainly two, 
and if my memory serves me aright three, species of Cemiostoma 
have been described from India. These references were evidently 
made from memory. It seems from Mr. Mann’s note ante, p. 606, 
that but two species are mentioned on the pages referred to and 
those two are from England, not from India. Nevertheless, I am 
still convinced that my memory is not utterly at fault, and that 
species of Cemiostoma have been discovered in India, and when 
the opportunity again offers I will look them up. Many months 
had elapsed after I saw the ‘* Trans. Lond. Ent. Soc.” before my 
note on p. 489 was written, and probably I have confounded in 
my mind the above references with some other. Eastern natural- 
ists surrounded by fine collections, libraries and every facility for 
study can scarcely appreciate the difficulties with which their less 
favored western brethren have to contend ; and Mr. Mann no doubt 
learned whilst in Brazil that want of the means of reference to 
what others have done is a very different thing from ‘negli- 
nce.” 
Cemiostoma, Phyllocnistis, many species of Lithocolletis and a 
few other genera of Tineina have a spot in the apical part of the wing 
which I have therefore called ‘the apical spot.” In Phyilocnistis 
and in Lithocolletis this spot is always at the apex: but in Cemio- 
stoma it is always at the inner angle. So characteristic of each 
of these genera is the position of the spot in it, that when the 
name of the genus is given and its spot is mentioned, the student 
who is familiar with the genus knows at once where the spot is- 
located ; just as Mr. Mann knew at once from my description the 
location of the spot in C. albella, although he had never seen the 
species and although I called it, for brevity, and not through 
negligence, “the apical spot” instead of ‘‘ the spot located at the eo 
inner angle.” But if the phrase “ apical spot” might have been — 
misleading had it stood alone, it could not have been so in the : 
description of C. albella, because it is esse ie with eos EE
