On this exhibition Lord Walsingham read the following 
notes : 
“The genus Cryptophasa (which has been very properly 
corrected to Cryptophaga by Mr. Meyrick), as well as the 
species published in Lewin’s ‘ Natural History of the Lepi- 
dopterous Insects of New South Wales’ (London, 1805), have 
been accredited to Lewin, but it would appear that they 
should be attributed to M’Leay on the authority of a letter 
from A. M’Leay to the Rev. W. Kirby, dated 20th February, 
1805, and published in Freeman’s ‘ Life of the Rey. William 
Kirby,’ pp. 226—27 (1852). In this letter M’Leay says ‘I 
have been describing eighteen Botany Bay Lepidopterous 
insects, which are about to be published by Lewin, with all 
their changes and natural history. Amongst them, there is 
a most distinct new genus (in my opinion), which I propose to 
name WVycterobius from NvuxtepoBios, noctu victum querens. 
The caterpillars form for themselves holes in the trunks of 
trees, where they hide themselves in the day-time: at night 
they come out and gnaw off leaves, which they drag to their 
holes ; and when they have provided a sufticiency for the next 
day’s consumption, they retire and feed leisurely, with their 
heads toward the mouth of the hole, which is covered by a 
curious contrivance.’ 
“This note can only relate to Cryptophasa, and this name 
was probably adopted as being more descriptive, if read in 
the sense of Mr. Meyrick’s correction of the word to Crypto- 
phaga, which was obviously intended. 
“The following notes have been compiled from a series of 
very interesting letters received from Mr. Dodd of Queens- 
land, to whose exertions I am indebted for the rich series of 
bred examples of many species, from which the few specimens 
exhibited have been chosen. 
“The larger species of Cryptophaga are very rarely met with 
in the perfect state, even by experienced collectors who spend 
the greater part of their time collecting in the bush ; indeed, 
it is not unusual for a whole season to pass by without a single
