Nephroeerus ftavicorni.t, Zett., Sfc, at Cambridge. — On July 2fitb, about 

 6.30 p.m., I went to my brother-in-law's bouse at Newnbam. The entrance faces 

 the Newnham mill pool, beyond which is the rough grassy pasture called Sheep's 

 Green, enclosed by the two branches of the river and intersected by old water- 

 courses, dry in summer. The east wind blew from the pasture straight to the door 

 of the house. There is a window on each side of the door. On these windows 

 were three flies : Pachygader ater, P. leachii, and Xephrocerus flavicornis. This 

 last was a fine female. T at once carried it off to show to my friend Dr. Sharp, 

 who beheld it with surprise and delight. It sat in the pill-box very much like the 

 male I took in the New Forest in June, 1903 (Ent. Mo Mag., vol. xxxix, p. 227). 

 Tiie head was close to the surface on which the insect rested, the body was curved 

 (the back concave) and sloped up at something like an angle of 45°. On July 16th, 

 at 3 p.m., the sun being hot, I found Mallota cimliciformis asleep in my green- 

 house, where Xylomyia maryinala and Steyana coleoptrata again occurred. On 

 September Rth my garden was visited by Cynomyia movtuorum. On the 27th of 

 the same month I moved to my present address.— Id. 



Xylomyia marginata, Mg., at Cambridge. — J)r. Sharp asks me to mention that 

 about July 24th he began to find Xylomyia marginata, Mg. (females), commonly 

 at Newnham among Lombardy poplars and felled walnut trees. He has obtained 

 larvffi from the latter, which have since been cleared away. — Id. 



[With reference to Mr. Jenkinson's note I may add that all the specimens of 

 Xylomyia marginata captured by me — about 50 — were of the female sex. More- 

 over, those found subsequently by Mr. Verrall in the same way were also all 

 females. This is of some importance as regards the habits of the species of the 

 genus ; for X. macidata, the allied form, is not very rare in the larval state in 

 the New Forest, and yet, so far as I know, but one specimen of the imago (and that 

 one a female) has been captured there. These facts seem to indicate that the 

 imago has some peculiar habit, perhaps that of ascending the trees immediately 

 after emergence, so that only females, which descend for the purpose of oviposition, 

 are met with by the Entomologist. — D. Sharp.] 



Plezostethus flavipes. Rent., at Carmarthen. — While on a visit to the town of 

 Carmarthen last August I had the opportunity of looking over a corn mill and 

 warehouse, and amongst some of the usual granary Coleoptera I found a living 

 brachypterous specimen of the Ilemipteron, Piezostethus flavipes, Rent., a species 

 not hitherto recorded from this country. I learn from the proprietors of the ware- 

 house that they receive grain from abroad, and amongst other places from the Black 

 Sea Ports. The insect is therefore probably an importation from those regions. 

 This is not however its first occurrence in England, as I find that Mr. Edward 

 Saunders has a specimen quite similar to mine, which is labelled " in Persian wheat 

 from Bussorah, found living in a warehouse in England." Nothing more definite 

 is known as to the locality of this specimen. 



It would of course be premature to claim this as an addition to our British 

 fauna, as there can be no doubt that it is an introduced species, and the evidence is 

 not yet sufficient as to its naturalization. But I am publishing this note in the hope
