Trochilium crabroniforme in Scotland. — In July, 1898, I suc- 

 ceeded in getting seven imagines of this species at Luffness and Aber- 

 lady, in East Lothian. In April, 1899, I obtained a number of larv* 

 in Salix caprea, near Midcalder, in Midlothian, some of those produced 

 the moths in the followmg July. In July 1900 I found the pupa? 

 common in willows at Newpark, also in Midlothian. I have seen the 

 borings of the larvie elsewhere, so it is not uncommon in this neigh- 

 bourhood. The Luffness examples were from poplar. — William 

 Evans, 38, Morningside Park, Edinburgh. Thcember SOth, 1902. 



Aquatic rhynchota about Bolton. — The following is the result of 

 a very interrupted year's collecting in ponds, all within four miles of 

 the town hall, and to the north and west of Bolton. I commenced on 

 January 1st, which was a splendid day as regards weather, and turned 

 up two specimens of ( 'uri.va fitriata ; I only took one more specimen 

 during the whole season, probably because I did not fish the same 

 pond again; the various species of (\irixa seem very locally distri- 

 buted ; as far as last season's experience goes ('. moesta and jyraeitsta 

 are both confined to a single pond; XoUmectaylatua and Cori.ca yeofi'royi. 

 I did no collecting whatever in Pel)ruary, as the ponds were all frozen, 

 April, July to October, and December were also blank months. 

 Velia currens, saw the first specimen on March 19th, very common ; 

 Gerris costae, three specimens in June ; Gej-ris odontoyaster, swarmed 

 in places, first taken in May ; Nepa cinerea, only took one specimen, 

 in 1901 took several ; Notnnecta ylauca, very common, usually along 

 with var. funata, but in one pond I took nine specimens of the type but 

 not one of the variety ; N. ylauca \a,r. funata, nearly as common as the 

 type ; Cori.ta yeaffruyi, common, has a habit of lying perfectly still at the
