Sphinx convolvuli. — At p. 110 ante, Dr. Jordan, after remarking on the abund- 

 ance of these moths this year, asks, "Are they immigrants or home-bred ?" 



In connection with this question, and the fact that the prevailing winds last 

 August and September were easterly, the following extract from Mr. Cordeaux's 

 paper on " The Spurn," in the " Naturalist " for August, 1884, may be of interest : — 



" Spurn has also long been famous for the capture of rare insects, many of 

 these, such as the Lepidoptera, unquestionably coming from beyond the sea. The 

 observations taken at Heligoland by Mr. G-atke, and recorded from time to time in 

 the migration reports, show that not only birds, but immense numbers of butterflies 

 and moths pass that island, travelling from east to west. Some years since many 

 Convolvulus Hawk-moths were washed up by the waves on the coast between Spurn 

 and Kilnsea, having doubtless perished in crossing ; and quite recently we received 

 three Death's-head moths taken on vessels far from land in the North Sea." — H.

Gelechia tetragonella in Norfolk. — In July last, whilst collecting Micros on a 

 salt-marsh near King's Lynn, I came across several specimens of what I considered 

 to be a strange Gelechia. Upon arrival home, I thought they would prove to be 

 only a form of Gelechia senectella ; but chancing to read Mr. Stainton's note upon 

 the new salt-marsh species, G. tetragonella, in the October number of this Journal, 

 p. 99, the idea occurred to me that my specimens bore a remarkable resemblance to 

 the insect there described. Not long since, Mr. Sang kindly sent me two of his 

 specimens, which appeared to be identical with some of my own. When writing to 

 him I mentioned this fact, and, acting upon his suggestion, I sent him some speci- 

 mens for examination, and he has in due course informed me that my insects are 

 undoubtedly G. tetragonella. 



Contrary to Mr. Sang's experience, I took nearly all my specimens on the wing, 

 between 7 and 8 o'clock in the evening. I noticed, however, that the insect after 

 getting up from the grass, quickly re- settled, and was not easily put up again. 

 Mr. Sang's observations on the appearance of this species when at rest I can 

 corroborate, but as yet I can give no clue as to the probable food-plant of its larvee, 

 suffice it to say that Artemisia maritima was absent from the locality. — Edwaed

 Fogonus littoralis, Birchington, abundantly; Bembidium b-striatum (2), Broad- 

 stairs ; B. ephippium, Birchington, abundantly ; Cnemidottis impressus, Noterus 

 clavicornis, Laccophilus variegatus, Birchington, sparingly ; Ggrinus distinctus, 

 Birchington, common, but confined to one ditch ; Enochrus bicolor, Pegwell and
