VOLUME I. 



Page 8. CiciNDELA hybrida. — Ci. maritima. De Jean. — It appears that this 

 insect is not the C. hybrida of the Linnean Collection; it certainly is not of 

 the Banksian, as mentioned in p. 175 of this volume : De Jean's name there- 

 fore must be retained for this species, as given in the second edition of my 

 Nomenclature. 



Page 18. CiciNDELA apria. — This insect is presumed to be the true Ci. 

 hybrida of Linnseus, from the fact of a specimen existing by that name in 

 the pre^fwf Linnean collection : it is, as above-mentioned, p. 175, the Ci. 

 hybrida of Fabr, according to the Banksian collection. The specimen 

 which I figured {pi. \.f. 1,) and described in p. 8 as Ci. riparia, is probably 

 one of the extreme varieties of this Protean species, as suggested in p. 19 ; 

 it is certainly not the type, as stated by Mr. Curtis in the second edition of 

 his 1st number. If it be the Linnaean species, of course his name must be 

 reinstated; but by whatever name the insect is called, it unquestionably had 

 not been distinguished as indigenous before I detected it, all the known 

 examples being confounded with C. maritima under the name of C. hy- 

 brida. 



Page 13. Dkypta emarginata. — Curtis, x.pl. 454. This rare insect was taken 

 by F. Walker, Esq. " in Sept. last, under a stone on the lias, near Lyme 

 llegis, Dorsetshire." — Ent. Mag. ii. p. 117. 



Page 44. Odacantha melanura — I found this insect on the banks of the Cam, 

 near Upware, on the 29th of June last. 



Page 176. Demetrias imperialis. — This species, which Gyllenhall considers 

 (I think erroneously) a mere variety of De. atricapillus, as he does also De. 

 monostigma, is now taken abundantly, in the spring, in the sedge-boats 

 employed in conveying " sedge" from the fens to Cambridge : it has also 

 been taken in situ near Cambridge itself.

Thorax, elytra and legs testaceous-brown, much darker than in De. atrica- 

 pillus, than which it is rather broader ; it differs also in wanting entirely 

 the black sutural margins of the elytra so uniformly present in that species. 

 Its size is that of De. imperialis, but it is much more robust and convex 

 than any described British species.
