collecting produced one worn specimen. In 1877 not even one 
rewarded me, in spite of some amount of work, and two or 
three fixvourahle nights. Last year, on the contrary, from July 
24th to August 4th either Mr. Pletcher or myself never failed to 
take at least one per night, and twice as many as seven ; while 
on August 3rd, the only really suitable night, Mr. Fletcher 
took no loss than thirty-two specimens, seeing many other-s. I 
was unfortunately not able to bo on the ground on this occasion, 
and indeed had only seven nights there, but still maiiagod to 
take a very fair series. The habits of this insect are yet unknown ; 
it will, however, no doubt be found to feed on the subterranean 
stems of the reed.* I hope another season may see this question 
definitely settled. Tlio imago is strong on the wing, and though 
powerfully atfectod by light, requires some activity to net it. 
In some seasons it is also attracted to the honeydew on sallow 
loaves. 
Nonagria cann.k This insect is plentiful throughout Hun- 
gary, roinorauia, and Saxony, and generally common in all 
Continental marshes. In this country it is recorded once from 
Devonshire, and has been taken as an extreme rarity in Sussex ; 
but most of our specimens come from the old Yaxley Fens. Of 
its occurrence there I have (through the kindness of Mr. C. G. 
llarrett) the following notes from IMr. Bond, Avhose acquaintance 
with those fenlands was most intimate, but who has unfortunately 
not published his information. 
About thirty-five years ago Mr. Bond collected from stems of 
Tijiilia latifolia round Whittlesea Mere, a number of pupm of 
Nomgria typluv, and on taking them home was surprised and 
delighted to find emerge from among them two or three N. camue. 
Peter Bouchard, who was at Yaxley with him, and had collected 
more pupm, obtained several specimens of N. cannoi among numbers 
of N. typhcc, and some of the resident Yaxley collectors bred a 
good many more in the same way. The late !Mr. Seely also is said 
to have himself collected and bred the specimens bearing his 
name in the collection of the Cambridge Anatomical ^[useum. 
These details, kindly furnished in letters by Mr. Bond and 
* Since the above was written N, brevilinea is reported to have been 
reared from a larva feeding externally on reed.
