260 [April , 
P. Phleas I never saw alive, but was shewn a single specimen which had been 
taken in 1869. In conclusion, I may mention that I have duplicates, in good con- 
dition, of many of the species mentioned in the foregoing list, and shall be happy to 
exchange them for good specimens of other European species.—R. P. Murray, Mt. 
Murray, Isle of Man, December 9th, 1870. 
Description of the larva of Miana arcuosa.—Thanks to the persistent efforts of 
Mr. James Batty, of Sheffield, I am able to offer a description of the larva of this 
species, as I believe for the first time. 
On the 23rd of May, 1870, Mr. Batty found several larvee and subsequently 
more, and also some pupz by searching the crown of the roots of Aira cespitosa ; 
and he kindly sent me three of the larvae on the 24th, which were then apparently 
full grown. To the two most advanced I gave some cut lengths of the lower part 
of the grass stems placed on a bedding of portions of the roots earefully picked to 
pieces, so as to ensure the absence of any other creature. The third larva after 
being figured and described, was placed in a pot with a small growing plant of the 
grass, which had also been carefully examined ; it soon crept into the middle of the 
small plant, and I did not see it again, for I was unwilling to interfere with it. 
The other two I looked at each time of feeding, up to the 2nd of June, when 
I found that one of them had partly spun together two pieces of the dried grass 
sheath; after that, being satisfied with this hopeful event, I did not disturb them 
further. 
The first moth, a male, appeared in the cylinder that confined the growing 
plant, on June 30th; only one of the other two emerged, on July 2nd, a female: 
and about the same time Mr. Batty reported his having bred a series of both sexes. 
The full-grown larva varies from five-eighths to three-quarters of an inch in 
ength, is moderately slender, the last three segments tapering a little towards the 
hinder extremity, the back just a very little arched in front, the head smaller than 
the second segment, and flattened above towards the mouth ; with these exceptions 
the figure is tolerably cylindrical, and its texture of considerable toughness. The 
ground is either a delicate cream, or pale flesh colour, with three transverse bars of 
pale brownish or deeper flesh colour on the back of each segment; these bars are 
all interrupted down the middle of the back by a distinct dorsal stripe of flesh 
colour still paler than the ground ; the sub-dorsal stripe is less pale and less distinct ; 
the spiracles are black and the region round them rather puffed ; the ventral surface 
and pro-legs of the pale ground colour: the head is glossy brown, darkest round 
the mouth; a paler brown equally glossy plate is on the second segment, divided 
by a slender line of flesh colour; and a still paler brown shining plate is on the 
anal tip ; the anterior legs are of the same pale brown colour. 
I must not omit to mention that the Rev. E. Hallett Todd most kindly sent me 
two larvze identical with the above, which he found in the roots of Aira cspitosa 
in May, 1867: but they died in the pupa state, and remained as an enigma un- 
solved till this season.— Wa. BuckieR, Emsworth, November 7th, 1870. 
Comparative descriptions of the larve of Chesias spartiata and obliquaria.—It 
is a great pleasure to me to acknowledge my numerous obligations to Mr. W. H.
