Note on the larva of Lavemn suh-bistrigella. — I observe there is a trifling dis- 

 crepancy between Dr. Rossler's notice of the habit of the larva (p. 105), and my 

 own (p. 106). Dr. Rossler states that it feeds down from the tip of the pod. I do 

 not think that it is at all the general rule, often indeed I have found the larva at 

 the lowor end, the upper part being full of seed. The position of the larva is 

 generally indicated by the thickness and curve of the pod. By holding it up to the 

 light, the small hole in the side through which the larva entered is often visible, 

 vrhen it cannot be seen otherwise. 



I strongly suspect that when young the larva feeds only on one of the four rows 

 of seeds contamod in the pod, though when larger it certainly clears all before it, 

 and I think it probable that after feeding along one row it turns round and feeds 

 back on the next, since it empties the pod before leaving it. — 0. G. Barkett, Hasle-

Bedellia sommdcntclla - -Last mouth the larva of this species, which is so 

 notoriously uncertain as to the time of its appearance, occurred abundantly in the 

 immediate neighbourhood of the Norwood Junction Railway Station. 



It is now some seven or eight years since I last saw any of these larvaa ; they 

 were then plentiful both at (Jreenhithe and Addington Road, Norwood, close to the 

 locality of their re-appearance. I have searched each season for them, but without 

 success until the present. — Ohas. Healy, 74, Napier Street, Hoxton, Oct. 3rtl, 1865. 



[The abundance of this species this year has been marked, not only in this 

 country, but on the continent. At Frankfort-on-the-Main, to my surprise, I found 

 it abundant on the garden convolvulus, Ipomcea purpu/rea ; since my return home 

 I have noticed it on the same plant here. — H. T. S., Lewisham, October 9th, 1865.] 



A nevj British Pterophorus. — At Frankfort last month, I noticed in the col- 

 lection of my friend, Herr Miihhg, a new plume, closely allied to ochrodactylus, 

 bearing the name dichrndactylus. The following day I visited Dr. Rossler, at 

 Wiesbaden, and again I saw the same insect, only with him it bore the name ochro- 

 dactylus, and for the other species a new name was proposed of Bertrami. Which 

 is the veritable ochrodactylus will probably be a very nice question. Herrich 

 Schaffer has no doubt figured dichrodactylus under that name, but the very faults 

 which he finds with Hiibner's figure would imply that Hiibner had represented the 

 other species. 



I am also disposed to think that the ochrodactylus of Zeller is also dichrodacty- 

 lus : for the present, and to avoid confusion, it may be advisable to drop the name 

 altogether. We have in heu thereof the two species dichrodactylus, Miihlig, and 

 Bertrami, Rossler. 



Dichrodactylus feeds on tansy {Tanacetum vultjare) in July, and the moth ap- 

 peal's in August. Bertrami feeds on Achillea ptarmica early in June, and the perfect 

 insect appears towards the end of that month. 



To describe the insects one requires a series of bred specimens of both, whereas 

 I have only a single bred specimen of dichrodactylus, this was bred from a pupa 

 on tansy at Chudleigh, in June, 1850, and which appeared in the perfect state 

 July 5th. Of Bertrami I have no bred specimens. 



Dichrodactylus has the apex of the anterior wings more prolonged, more falcate 

 than in Bcrt/rami, and the brown scales on the hind margin of the third feather of
