COtiEOPTERA. 105 



and increase in RJn/iicoj)hora and Pln/tophw/a, in the south, are very 

 obvious. In many genera, too, where members are perhaps equally 

 common in both localities, one species predominant in the north seems 

 to be replaced by another equally predominant in the south. Reverting, 

 however, to species actually encountered : — The valley of the Brent 

 between Hendon and Hanwell seems to be a locality not specially well 

 worked by coleopterists, and here a few species have occurred which 

 may be worth notice. By the margin of the stream itself, among 

 shingle and on the exposed mud, were taken Ijcinhidiiiui (ibUi/innii, I), 

 articidatuiii , Tachi/iim flaritar>iis, and by the edge of the Hendon Lake 

 B. relax and Tachi/um conculur. In tufts of grass and reeds in a small 

 marsh near the brook occurred StoiolopIiKs ref:jicrtinus, M>/llai)ta iutrr- 

 inediay Lestcva punctata, Stenufi melanupuK, JJri/a.vi.i iiniircam, Ti/c/iiis 

 nUier, Mantura ohtmata, &c., and, in pools of the same marsh, Coptiatiin 

 ai/iliii was most abundant in May. Here also were taken Hydaticus 

 .se))iini(/er, Rhantns f/rajni, Hj/droporus au;ii(ntatus, and H. lituratus, 

 Hi/drochus cloiKjatux and H. angiistatiis, while sweeping in this marsh 

 and vicinity resulted in Axinotarsiis nificollis (abundant in long grass, 

 July), AntJiucditi lis fasciatiix, Conjmhitcs tcaacllatKs, I'seudoftti/p/iliis piliini- 

 nxx (off Matricaria), Ceutltorrliijncliun iiiekotostictiiK, C. alliariac (iiiorna- 

 fiis), I'/ii/Uiitnta ncliripcs, &c. From under bark and in fungus I was 

 fortunate in taking hhitlua pUcata with commoner species such as 

 Atoiiiaria jiiiiitaria, Litan/us hifasciatus, J\Ji/cet>)ji(iri(s atuiiiariiis, Jl/iiza- 

 phai/us cribratits, Xjiliqdiilns popuhwun and Ui/jxiphlociis hicolur (under 

 elm bark only), and in flood refuse, Ocyjms fiiscatas. Oi Richmond 

 Park and Wimbledon Common I had from various notes and published 

 lists of localities formed high expectations. The former, however, 

 seemed at first sight to my inexperience a difficult and even unpromis- 

 ing tract, while the latter far exceeded in apparent promise my anticipa- 

 tions. From Wimbledon, however, I have been able to extract but 

 little worth record, although the yield of species was large. The only 

 beetle new to my experience being Ili/droporiis i/rajn/laris, which was 

 abundant in shallow pools in August. In Richmond Park, on the 

 contrary, I was able to take several species I had never previously 

 met. Under bark occurred Lacnidjddoeas biuiacidatas (one), I'arauialiis 

 ^ttariciirnis, Cciijlon histcmidcs, Haiiialota titspidata, I'ldin'opara corticalix, 

 Lcjitiisa fiintida, -cinil fsc/uioijldssa nifajticca. In park refuse 7 '/(/7n/(?A//.s 

 (jiiisijiiiliaritis var. diiiiidiatiis was not uncommon, with one specimen of 

 I'hilontlnis umbratilis, and, in dead leaves, Xdtinjdiiliis rutipcs. Farnham 

 Royal Bucks, near Burnham Beeches, a region of woods of beech, oak, 

 and hazel, appears to me a most excellent entomological district, and 

 one from which few records have been published. Here I was pleased 

 to take fli/drajiuriis iti'i/lcrtiix (swept from reeds) with Hclop/iunis )u(bilii!< 

 and, in powdery fungus on a beech stump, Sphi)idiis didnns. By sweep- 

 ing and beating I took L'l[/tiis iiij/sticas, ('oripuhiti's liohmericens (in 

 whitethorn flowers), Cassida ittata, Sj/binia jiotoitillac, S. vtiniita, 

 (ji/iiinctnDt )i(i<tis, Miarus canipanulac (in harebells), Illiiiiinichns castor, 

 Loclnnara cratariii, llhipicldtcs oicorirois and 11. ajdit/iahiiiciis, with 

 many other species. A visit paid to the classical locality of Hcadley 

 Lane, Mickleham, in .Time last, was rewarded by the capture of a fine 

 specimen of the scarce Mi/niicda)iia haimrtlii, and among other more 

 abundant, but to the northern collector quite as unfamiliar, species, I 

 took 'r/ianasiiiuis fdiuiicariiis, JShiiijctlws jiahiiutus and sulidus,
