This insect resembles a parcel of straws united together, being entirely wingless, and is indeed, but incorrectly, stated by Drury to be the larva of an insect like that at Fig. 1. Its general colour, as he was informed, is green; but having received it in spirits, it had become of a dusky brown colour. Head small and long, reaching almost to the fore legs. Eyes round and black. Antennæ like hairs; being as long as the insect itself. Body, which extends from where the hinder legs are placed, consisting of nine segments, almost as long as the remaining part of the insect; those legs being fixed nearly in the middle, at a small distance from whence are placed the middle legs. This insect belongs to a singular and numerous family, known to collectors by the names of Spectres, or Walking-stick insects; and others, Walking-leaves, from the strong resemblance which they exhibit to pieces of dried sticks and detached leaves. The insect here figured appears to be in an immature state, and would probably in its final state have acquired wings. Our author appears to have been aware of this, but he incorrectly describes it as the caterpillar of an insect like that at Fig. 1. END OF VOL. I. G. NORMAN, PRINTER, MAIDEN LANE, COVENT GARDEN. NOTES. [1] The original title of this work, Vol. I., was "Illustrations of Natural History, wherein are exhibited upwards of two hundred and forty figures of EXOTIC INSECTS, according to their different genera, very few of which have hitherto been figured by any author, being engraved and coloured from nature, with the greatest accuracy, and under the author's own inspection; on fifty copper-plates; with a particular description of each Insect, interspersed with remarks and reflections on the nature and properties of many of them, by D. Drury, 1770." The second volume containing upwards of two hundred and twenty figures, on fifty copper-plates, appeared in 1773; and the third containing upwards of two hundred figures, also on fifty plates, was not published until 1782. The majority of the plates were drawn and engraved by the celebrated Moses Harris, but some of the plates in the last volume were by a different hand. [2] A similar compilation bringing down the science to the present time would be invaluable, even with all the inaccuracies charged to Gmelin. [3] This is evident from Gmelin's occasionally copying some of Fabricius' erroneous references, e.g. Bombyx ornatrix, Gmel. p. 2444. with a reference to Drury, v. I. t. 74. as in Fabr. Syst. Ent. p. 586. instead of tab. 24. [4] Subsequently purchased by the Linnæan Society. [5] This contemplated edition of the Syst. Nat. never appears to have been published. [6] I find no notice of this contemplated fourth volume amongst Drury's manuscripts. [7] See Goedartius, translated by Dr. Lister.
