 Hackney, November 4, 1881. 



Sphinx gonvolvuli at Norwich. — On September 22nd I 

 captured a specimen of Sphinx convolvuli at rest on the rails 

 of the Wellington statue in the market-place, evidently attracted 

 by the electric light. On the same afternoon Mr. P. E. Dyball 

 took one from the electric lamp. On September 24th another 

 was picked up on the ground under the electric light, and given 

 to Mr. Dyball. On September 30th a friend of Mr. Dyball's, 

 named Dodd, captured one on the back river. — H. J. Thouless ; 

 Lower Close, Norwich, October 5, 1881. 



Ennomos autumnaria. — After the announcement from M. 

 Wailly of his having sent out a great number of foreign eggs of 

 Ennomos autiimnaria, all interested in pure British Entomology 

 should endeavour to carefully examine, and, if possible, guard 

 against introducing any doubtful specimens into their cabinets ; 

 and as my name is connected with the Deal examples, I should 

 like to place on record faithfully all I know about them. From 

 1877 I have each year spent a month or five weeks entomologising 

 at Deal. In the autumn of 1878, after having several times met 

 Mr. R. Harbour collecting on the sand-hills, I went to look at his 

 collection. In it I found he had several NQvy good species that he 

 had mixed up with other species, for although an ardent worker 

 he was not well up in obscure forms. Amongst his " thorns," 

 under Ennomos angularia, was a female E. autumnaria, worn, 

 tips of wing broken, but still unmistakably autumnaria. He had 

 also two or three male specimens, more or less imperfect, that 

 struck me as different to our London type of angularia ; still I 

 was not convinced that ihey were anything else than strongly- 

 marked angularia. The female I then and there placed for 

 him under its proper name, and advised him to keep a sharp look 

 out on the gas4amps for more ; this was in 1878. Two 3^ears 

 after, in July, 1880, Mr. Harbour showed me his breeding-cage, 

 in which at the time were one or two imagines of E. tiliaria just 

 out of pupa, some spun-up pupa, and also two, or possibly more, 

 long Ennomos larvae. Not knowing them, I asked what they 

 were. He told me they were E. angularia. As I had never bred 

 that species I was desirous of doing so, to get varieties of this 

 variable species ; so asked him if he bred these and got eggs to
