difference of form in the scales of the 
wings and of the hooks. 
3. “ The English Lepidoptera, or the 
Aurelian’s Pocket Companion, containing 
a Catalogue of upwards of 400 Moths 
and Butterflies, &c. London : Robson, 
1775;” 8vo; plate of dissections, pp. 
66. I have seen several copies of 
this work. 
An edition at Exeter in 1786, which I 
have found recorded, I have not met 
with. It is perhaps an error. 
4. “ An Exposition of English In- 
sects.” 
This work probably appeared in num- 
bers; I know three different title-pages 
of 1776, 1781 and 1782, which are 
enumerated as so many editions. But it 
seems doubtful whether they can be truly 
considered as editions ; the text is 
throughout precisely the same, but of 
the plates at least thirteen have been re- 
engraved once or even twice. The titles 
are — 
“ An Exposition of English Insects, 
with curious observations and remarks, 
wherein each Insect is particularly de- 
scribed, &c. London: Author, 1776, 
and sold by Messrs. Robson, &c.” Pp. 
8 and 166 and 4 index; 4to ; 50 plates, 
with frontispiece and plate of dissections. 
The text is in two columns, English and 
French ; there is also a French title- 
page. Sometimes (Brit. Mus.) there is 
also another plate of the scheme of 
colours. 
The next edition has precisely the 
same title in English and French but 
“ London : printed for the Author and 
J. Millan, &c., 1781 ” (number of pages 
and plates as above). 
The third edition has on the engraved 
title page “ An Exposition of English 
Insects ; including the general classes of 
Neuroptera, Hymenoptera and Diptera, 
&c. London : White and Robson, 
n 
I 
1782 ” (number of pages and plates pre- 
cisely as before) . 
In the British Museum I found all 
three editions, and I took the trouble to 
compare closely all the plates. The 
plates 8, 13, 14, 16, 18, 19, 27, 33, 34, 
39 and the Plate of details are reversed. 
Plates 4, 6 and 15 are reversed, but the 
individual figures remain in their places. 
Besides this the edition of 1776 has 
plate 23 marked with 1779 and plate 26 
with 1780, and in the British Museum it 
has also the title page of 1782. Hence 
I suspect that the work came out in 
numbers, and that on the sale increasing 
some of the plates were re-engraved, but 
the whole only appear to me to form one 
edition. 
I may however remark here that the 
copy of 1781 in the British Museum, from 
the Banksian Library, is far better coloured 
than any other I have seen, and in deter- 
mining the smaller species I would re- 
commend that reference should be made 
to this copy. — Da. Hagen, August 31. 
[We should be very glad to hear from 
any of our readers who possess copies of 
Harris’s works, as when the books are so 
scarce and the editions so different each 
copy possesses a considerable bibliogra- 
phical interest.]
