this has caused some entomologists to doubt whether P. concinnus is truly 

 distinct therefrom. The cupreous form I have seen only in Mr. Champion's 

 collection (Christchurch). 



P. COCHLEARIiE. 

 In this species the humeial callus is indistinct ; the first and second joints 

 of the antenna; are obscurely marked with red beneath, and the club is 

 comparatively slender ; the tips of the tibise are usually red beneath ; and 

 there is only a very slight red pigmentation of the liind margin of the last 

 ventral plate. This common insect is more varialjle than the allied forms. It 

 is generally of a bright bluish-green colour, but dark violet specimens occur. 

 P. cochlcarise is usually smaller, narrower, and more convex than P. armoracise, 

 but broad and less convex examples occur, which at first sight greatly resemble 

 the latter, but these may be certainly distinguished by the comparatively 

 indistinct hvuneral callvis. 



The tliree species also show differences in the form of the sedeagus. 

 In P. concinnus the apical portion is longer than in the other species, 

 more curved, but parallel- sided. In P. armoracim this part is narrowed 

 towards the tip, while in P. cochlearix the apical part is only about 

 half as long as it is in P. concinnus.

NOTES ON SOME COLEOPTERA FOUND AT BAETON-ON-SEA, 

 HAMPSHIEE. 



BY C. F. SELOUS, M.B., M.R.C.S., L.R.C.P. 



As this locality is not very M-ell Icnown, it may be as well to 

 explain that Barton is situated on the Hampshire Coast, almost 

 immediately opposite the Needles of the Isle of Wight. In collecting 

 in tJiis district my attention has been principally directed to the under- 

 cliff, and, though some interesting captures have been made, yet, 

 considering the extent and varied character of the ground, the insect- 

 fauna on the whole is disappointing. Of insects, however, large 

 numbers must be destroyed annually, particularly during the winter 

 months, owing to the continual subsidences which are taking place. 

 Thus I have been frecj[uently disappointed by the destruction of some 

 choice himting-ground, and the spot which one year teemed with some 

 species of beetles may be almost barren next year owing to the complete 

 alteration in the character of the ground, a marshy spot becoming 

 quite dry or vice verso. 



Acupalpus flavicollis, Stiu-m. — This is one of the commonest beetles on the 

 undercliff. By grubbing at any spot where tlie groixnd is moderately damp at
