regard to nesting sites. At Messingham Water-mill, when the 

 fish were coming up the beck in the spring, a pair that had their 

 nest in a few Scotch Pines close by, took dace regularly from 

 the ' backwater ' and ' slack ' when the mill was not running. 

 The water at times was perfectly congested with fish unable 

 to ascend higher on account of the dams. I have watched them 

 taking the fish in the gloaming, and found the bones of dace, 

 gudgeon, and ' pickerel ' or small jack in their castings.

COLEOPTERA NEW TO YORKSHIRE.

 Hull. 



Pogonus chalceus Marsh. — On May 27th and June iith 

 I found this beetle occurring in some numbers at Saltend 

 Common, on the Humber shore, about three miles east of Hull. 

 The specimens were obtained by loosening the cracks in the 

 low clay cliffs (from two to three feet in height) which are 

 situated just above ordinary high- water mark on the banks 

 of the tidal creek which forms the eastern boundary of the 

 common. The time of day on each occasion on which I ob- 

 served it was towards sunset, but it is probable that the species 

 will be found to occur plentifully during the sunny periods of 

 the day, on the edge of the mud left by the receding tide. 

 Dr. Wallace, of Grimsby, obtains the species commonly on 

 the Lincolnshire side of the Humber, and I have little doubt 

 that it will be found at other places along the estuary if the 

 right localities are searched at the right time. Many of the 

 typical saltmarsh species such as the Pogoni appear fairly 

 regular in their period of maximum abundance. In the same 

 cracks as the Pogonus were found large numbers of immature 

 Dichirotrichus puhescens, evidently just emerged from the pupal 

 state, which in a few weeks' time will be found under every 

 stone and clod on the Humber shore, in company with the 

 ubiquitous sand-hoppers. 



Donacia bra^cata Scop, [nigra, F.).— On June 12th I 

 found this fine species occurring in profusion on the Phrag- 

 mites commune growing in a brackish ditch parallel to, and on the 

 inner side of the embankment on the Humber shore, about two 

 miles east of Hull. The specimens were first obtained towards 

 sunset, by a chance sweep with a net among the Phragmites, 

 and on search being made were found concealed, usually in
