APPENDIX. 573 



" Barham, Nov. 30. 1S05. 



" Sir, — When your obliginpj letter and box of insects arrived here I was in 

 London, and did not return till towards the middle of October, when Mr. George 

 Eodwell 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 1 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 I am able. Your letters to 

 my friend Marsham, of which he had indulged me with a sight, excited in ray 

 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. Qaercus, 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 Cure. Avellancc, Marsh.: it has black antennce. 

 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 antenna, 

 and rufous tibia;. In both these species the antenna; 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 antennise, 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. I have it from Sweden of all 

 shades, 



" 4. It comes veiy near Dyti^eus 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 Z>. lineatus of Fabr, and Payk., 

 which I have from Major Gyllenhal, my Swedish correspondent. I have only 

 a single specimen of 1>, 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.Jiexnosus, E. B. ; D. pictus, Fabr. 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 Elaphnis 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. okvs, 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 Jlavipes {Eh' 

 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, 52, 

 53, 54. 56, 57. 73. 75. 77 ? 80, 81., of ' Ent. Brit.' 



" 7. Carabus truncalellus, ' Ent. Brit.'
