114 Mr. J. Curtis on some nondescript or imperfectly 
to and the size of O. cespitana, Hiib.,”’ an opinion which has re- 
cently been confirmed by Mr. Doubleday. 
19. 9. O. cespitana, Curt. ib. Mr. Doubleday being satisfied 
that this is not Htibner’s insect, but one described in the ‘ Isis’ 
by Mad. Lienig as 7. palustrana, my name must be transferred to 
the preceding species. I regret to see it separated from Ortho- 
tenia and made one of a new genus called Mizxodia by Guené, 
for surely it cannot be necessary to form a genus to receive a 
species so closely allied to O. cespitana, that one may be mistaken 
for the other : sections are infinitely better, and to these we must 
come at last, when we have been overwhelmed with the burden 
of generic nomenclature. This extravagant rage for making 
genera has however had its use, having led to a refinement of 
discrimination which has been most beneficial in correcting the 
slovenly habits of investigation that attached even to the mag- 
nates of the last century and somewhat later. 
20. “Genus 963, 6. Cochylis marmoratana, Curt. Brit. Ent. 
fol. 491. The species since described under the name of /uteo- 
lana by Stephens, and figured by Wood, pl. 37. f. 1140, appears 
to be a variety of my marmoratana. 
21. Genus 967. Peronea, Curt. Brit, Ent. fol. & pl. 16. Since 
this genus was published in 1824, prodigious strides have been 
made in entomology, and large quantities of these Tortricide have 
been bred by Mr. Doubleday, who considers a vast number of 
the species merely varieties of two types, viz. 7. cristana, W. V., 
and T. hastiana, Linn. If Lepidoptera vary to such an extent, 
it may be well asked, ‘ What is a species ?’

22. Genus 991”. Anerastia, Zell. ; Abraxes, Guide. 
2. Farrella, Curt. Cab. Expanse 11 lines ; and similar in form 
to A. Marisci or T. lotella, Hib. pl. 48. f. 334. It is whitish, 
the horns are very slender and flesh-coloured, as well as the back 
of the thorax: superier wings narrower than in Joftella, gray 
freckled with brown ; the costa brown, with a white streak from 
the base to near the tip, and a suffused space of ochreous flesh- 
colour along the centre ; before the middle, on the inner margin, 
is a black dot, and three more beyond the middle in a curve, one 
being on the costa, another on the inner edge of the white streak, 
and a third below it: inferior wings pale silky smoky lilac. 
Yor a specimen of this pretty and distinct species I am in- 
debted to Mr. H. F. Farr: two or three were taken at the North 
Lighthouse, Lowestoft, the beginning of June 1840.
