Cornwall that I considered to be this sjjecies ; but when it was submitted to 

 Mr. Newbery he pronounced it to be a variety of P. atra, and Mr. Britten who 

 saw this example last autmnn also considered that it was not diademata. 



On the 1st Jiine last. Commander Walker, my daixghter and myself foimd a 

 colony of a considerable niunbor of black Phyllotrcta on two or three very 

 large plants of the somewhat local Crucifer Senebiera didyma Pers., at Milford- 

 on-Sea, and I secured a score or two for study. I found there were three 

 species among them, two being atra and cruciferae, and the third doubtful. A 

 series of dissections has been made, and these show that the third species is 

 diademata, and that it is distinct from the other two. Dissection of the 

 Cornwall example proves that it is also diademata as I supposed. 



The sculpture of the head is not to be relied on, but the sexual characters 

 make the species easy of determination, the form of the terminal segments of 

 the abdomen rendering this sex recognisable at a glance, owing to the large 

 depression at the tip of the abdomen and the groove leading to it. The female 

 is also easily distinguishable by the shape of the sperniatheca, which is shorter 

 and more dilated at one end than it is in P. atra. This sex also is usually 

 larger than in atra, less shining, more convex, and with more rounded less 

 parallel-sided outline, as well as a denser and more confused punctuation. 



Since I captiu-ed the specimens at Milford I have also met with the species 

 near Brockenhurst, in a very different spot ; I have also found two other 

 individuals, given me many years ago as P. atra by the late E. C. Rye. These 

 two examples were no doubt found in the London district, and I infer from my 

 experience that P. diademata is probably fairly common in England, at any 

 rate in the south of the country. — D. Sharp, Brockenhurst: June 2oth, 1915. 



Creophilus maxillosus, v. ciliaris, at Chiswick. — I have a nice female of this 

 variety, brought to me alive by Miss G. M. Shepherd. The specimen was found 

 in her garden at Chiswick on June 9tli. — Edward A. Watbrhouse, 6, Avenue 

 Gardens, Acton : Juiie 23rd, 1915. 



Ochthebius potveri Bye, etc., at Exmoxdh. — During a recent visit to Exmouth 

 and Budleigh Salterton, I spent some time examining the fresh water trickles on 

 the red sandstone cliffs, and, as might be expected, the species met with were 

 mainly the saiiie as those captured by the late P. de la Garde and myself at 

 Shaldon, to the west of Teignmouth. The following may be noted : Bembidium 

 saxatile, B. stephensi ; Laccobius purpurascens, not rare, with one or two other 

 species of the genus ; Ochthebius poxveri, a single example (the other Devonshire 

 records are, one from Seaton and one from Bovisand, the latter taken by 

 Mr. Keys in 1911) ; Hydraena nigrita; Tachyusa atra; Lesteva fontinalis, not 

 rare, L. pubescens ; Dianous caerulescens ; Stenus guttula, S. nitidiusculus ; 

 Actobius signaticornis ; Ancyrophorus aureus; Lathrobium angustatum ; Homa- 

 lota gemina ; Myllaena brevicornis ; Uelodes inarginata ; Barypeithes sulcifrons ; 

 Hypera pollux and its var. alternans. Bruchus rufipes {luteirornis), one male, 

 swept at Budleigh. — G. C. Champion, Horsell, Woking : July 7th, 1915.
