APPENDIX. 573 
“ Barham, Noy. 30, 1805. 
“ Sir,— When your obliging letter and box of insects arrived here I was in 
London, and did not return till towards the middle of October, when Mr. George 
Rodwell had left Suffolk, or I would, if possible, have returned your box and 
an answer by him. Since that time I have been so busily engaged, principally 
in preparing my paper upon the genus Apion for the press, that I have not had 
time to consider the contents of the little box you were so good as to send. 
Having now despatched that business, and’ besides having an opportunity by a 
private conveyance of getting this as far as Pocklington in Yorkshire, I shall at 
length endeavour to answer your queries as well as Tam able. Your letters to 
my friend Marsham, of which he had indulged me with a sight, excited in my 
mind a strong inclination to correspond with a naturalist who, from his very 
outset, seemed to enter so deeply into the subject, —who, so far from falling 
into the errors usual with beginners, determined his species with the judgment 
and precision of the most experienced naturalist. But I leave prefacing, as I 
have but little time allowed me to prepare my letter. 
“1, Your Curculio No. 1. I have long been acquainted with, and have al- 
ways taken it for the Cure. Quercus, Linn. The description in ‘ Faun. Suec.’ 
mentions the triangle observable in certain lights at the base of the elytra, A 
correspondent of mine in Sweden, to whom I sent it, writes me word that it is 
certainly C. Viminalis of Fabr. and Paykull. I have not Panzer’s ‘Ent. Germ.,’ 
only his ‘ Faun. Ins. Germ. Init.’ ; therefore I cannot say whether the insect in 
question appears to me his C, Betuleti. 
“2. The specimen sent me is Curc. Avellane, Marsh,: it has black antenne. 
That taken upon the willow, which I once found here, is Cure. Saliceti of Fa- 
bricius. It is distinguished by a white scutellum, rufous stalk to the antenne, 
and rufous tibix. In both these species the antenne are broken, though the 
first joint is not so long as is often the case ; but the insects being very minute, 
it is not easy to unfold the antenns, and they usually are so closely folded as to 
look as if they were inserted at the base of the rostrum, and were unbroken ; 
but I have specimens of both, with the antenna unfolded. 
“3. Cure. variabilis of Fabr., doubtless ; but I think Paykull right in giving 
it as a variety of C. nigrirostris. What hairs are left upon the elytra are green, 
and the colour of the substance of the elytra in nigrirostris is rufous. C. va- 
riabilis is probably a late-disclosed specimen. Ihave it from Sweden of all 
shades, 
“4. It comes very near Dytiseus lineatus of Marsham, but may be distinct, 
unless, as is probable, it is a sexual variety. My specimen of D. lineatus is a 
female, and No. 4. is a male. Neither of these is D. lineatus of Fabr. and Payk., 
which I have from Major Gyllenhal, my Swedish correspondent. I have only 
a single specimen of J. lineatus; one more I took and gave Mr. Marsham. 
No. 4. I never saw before; for the specimen you sent Mr. M., as this variety, 
was a black abdomened one. ‘ 
“5, D. flecuosus, Ei. B,; D. pictus, Faby. Payk.; arcuatus, Panz. xxvi. 1.? 
“6. Carabus, I think, with you, that this is only a variety of C. litioralis, 
I had not seen it before. Observe, that most of these little Carabi, which we 
find in moist places, are of a different habit from the others. ‘They come near 
to Elaphrus of Fabr., and are reckoned as such by some authors, but I think 
they would form a distinct genus. I had named it Ocys (Gr. dibs, celer), but 
Latreille has called it Bembidion (‘ Hist. des Crustac. et Ins.’ vol. iii, p. 8., and 
Vii. p. 232.). The exterior palpi are exactly those of Cicindela flavipes (Ela- 
phrus), and so are their habits. ‘The last joint but one of the former is in- 
Crassate, and the last very minute and setiform. To this genus belong 51, 62, 
53, 54. 56, 57, 73. 75. 77 ? 80, 81., of ‘Ent, Brit,” 
“7. Carabus truncatellus, * Ent, Brit,’
