Bythinus burrelli, Den., in the Derwent Valley, etc. — In Octo- 

 ber, 1906, I found a female example of Bythinus burrelli amongst hay- 

 stack refuse in Axwell Park. Though not recorded by Bold, a single 

 male has been taken by Hardy in the Wooler district, and another 

 male by Blatch, near Hartlepool. I am now able to record B. 

 puncticollis, Den., B. validus, Aub., B. bulbifer, Reich., B. curtisi, Den., 

 B. securiger, Reich., and B. burrelli, Den., from the Derwent Valley. — 

 I would also mention the occurrence of B. validus, Aub., with B. 

 puncticollis, Den., and B. bulbifer, Reich., from a bag of moss which 

 my friend, Mr. Gillanders, kindly sent me from Alnwick (January, 

 1907). B. validus previously rested in our Counties' list on a single 

 example taken by myself at Gibside early last year. — R. S. Bagnall,

Agabus affinis, Payk. and Agabus unguicularis, Thoms., as War- 

 wickshire insects. — In my " List of Warwickshire Coleoptera " (Vict. 

 Hist Warwickshire, i., p. 87), I recorded Agabus affinis, Payk., and A. 

 unguicularis, Thoms., on the authority of the late W. G. Blatch. All 

 these specimens on which these records were made turn out to be A. 

 affinis, so that A. unguicularis must for the present be struck out of the 

 Warwickshire list. The two species are very closely allied, but the 

 difficulty of determination can be overcome by reference to Mr. 

 Balfour-Browne's lucid notes (Ent. Rec, xviii., p. 273), and I am 

 indebted to him for his kind assistance in this matter. From the 

 known distribution of the two species in Britain, it appears that where 

 one is common, or moderately so, the other is either very rare or absent, 

 and this fact led to a closer examination of the specimens. It is interest- 

 ing to have A. affinis as a Warwickshire insect to the exclusion of A. 

 unguicularis, as, of the two, the latter would have been the more likely 

 to have occurred with us. As suggested by Professor Hudson Beare 

 in his " Retrospect of a Coleopterist for 1906 " (Ent. Rec, xix., p. 29) 

 it would be well for collectors to carefully examine their specimens of 

 the two species with the assistance of Mr. Balfour-Brown's paper, and 

 correct any inaccurate records that may have been made. — H. 

 Willoughby Ellis, F.E.S., Knowle, Warwickshire. February 28th,

Leptidea brevipennis, Muls., and Gracilia minuta, F., at 

 Lulworth. — During July, 1905, I spent a few days at Lulworth, the 

 weather was very hot and general collecting most unsatisfactory ; 

 everything was dried up. The last morning of my visit, I saw in the 

 bright sunshine several specimens of Leptidea alight on a whitewashed 

 wall, and I captured half-a-dozen, and traced their origin to the red 

 osiers, called " red witheys " by the fishermen, who cultivate and use 

 them for lobster-pot making. I also found Gracilia minuta, F., 

 breeding in them. The osiers had recently been cut and stored away 

 in a shed, and I found dead imagines in them. There is no doubt that 

 the insects pass their preliminary stages in the growing " witheys." 

 The fishermen told me that they did considerable damage by their 

 borings, and during the operation of bending to make the lobster-pots, 

 the osiers break where the beetles have perforated them. I saw the 

 spot where the osiers were grown, and I was assured that no foreign 

 ones were ever imported. Amongst other captures during my visit were
