tion ceases, and £. vagars begins : there too you find the boundary line of the 
serpentine district. In explanation I can only suggest that the plant needs a 
large amount of magnesia, of which substance serpentine is largely composed. 
The only other well known rock containing it is magnesian or mountain 
limestone. On this of course no heath can flourish, as even ordinary hard 
water, from containing lime, is fatal to all that family; hence also the entire 
absence of that order, excepting the aréutfus in gardens, from this district. * 
Of other heaths Z. cinerea, £. tetralix and C. vulgaris occur sparingly and in 
a stunted form.” 
Mr. Cumminc then gave a list of rare plants, and varieties of 
common plants, peculiar to the Lizard, as well as of those which 
he considered peculiar to the south-west corner of England, 
deducing from their occurrence in Spain and Portugal that a neck 
of land stretched across the Bay of Biscay, from Cornwall to 
those countries. These plants are, however, to be found in any 
manual ; we therefore only insert one passage referring to them :— 
‘‘But the best is yet to come :—Just two days before my departure, near 
St. Knighton’s Keve, halfway between Boscastle and Tintagel, I gathered wild 
specimens of Adtantum Capillus Veneris (Maidenhair) and 7richomanes radicans 
(Killarney Bristle Fern.) Never did miser gloat so over his treasure as I did 
when I scraped out from an obscure crevice in the rock, with my finger nail, a 
piece of 7richomanes, bearing a frond not half-an-inch high, and scarcely to be 
distinguished by the uninitiated from the lichens, amid which it was growing. 
I believe that to be the only spot in England where that fern has yet been found. 
«* And now I must conclude with a word or two about my experience in the 
Entomology of Cornwall. I had hoped to have shown you, before this, a bred 
specimen of the Striped Hawk Moth, ( Detlephila livornica, ) which indeed had 
been a treasure, had fate allowed. A  full-fed larva I found at Loo Pool, 
feeding on dock, which soon retired under earth. About a week after, I had 
to leave the Lizard, and, in spite of every precaution in packing, the jolting on 
the journey proved fatal. Besides this, the Entomology of the Lizard has 
nothing peculiarly striking, though there are many species individually good. 
Of butterflies, the Silver-studded Blue, (P. qgon,) was very plentiful on the 
heather when we first went; beyond this there was nothing else worth mentioning. 
I must now content myself with giving a list of the chief moths I captured, 
adding notes where necessary :—7 rechi/ium ichneumoniforme, flying in sunshine 
along grassy banks on sea coast; 7: Philanthiforme, similar to above: I had 
only heard of it previously from the Isle of Man; Lithosta Griseola and Complana, 
both at Lizard; Zpione Apicaria, a good series, occurring at Lizard and at 
Boscastle ; Acidalia emutata, a few at Boscastle ; Bryophila Glandifera, one at 
Lizard; Agrotis lunigera, one at Lizard; /fecatera serena, one at Lizard; /lusia 
Orichaleea: 1 had the pleasure of taking a specimen of this rare and beautiful 
insect, flying at-a lamp in the hotel, Boscastle. I have not seen a capture 
recorded before for many years. Harding, of Deal, used to take it somewhere, 
but where, he never revealed; and, suddenly, as rare things will, it vanished. 
Ennychia cingulalis, on dry banks, very common ; £xdotricha flammealis, at 
Boscastle; Stenia punctalis, not rare at Lizard ; Leptogramma literana, sparingly 
in oak wood at Boscastle ; 7éras Caudana, common at Boscastle; Déctyopteryx 
Hfolmiana, locally at Lizard and Boscastle; Pedisca profundana, abundant at 
Boscastle: Dicrorampha petionana, common at Lizard; Xanthosetia Zoegama,
