and found their necks full of troublesome tumours ; whilst he himself suffered 

 for several days from having handled them. In these respects, they are very 

 similar to the celebrated Pityocampa of the ancients, and which is the cater- 

 pillar of another species of this genus, which feeds upon the fir. *Poecilo- 

 campa populi, *Hypogymna dispar (the gipsy moth), *PsiIura monacha 

 (the black aixhes), *Dasychira fascelina (the dark tussock), *Psyche fusca, 

 and -j-Limacodes Zbstudo. Amongst the Litliosiidcc, *Callim6rpha miniata, 

 *Lith6sia complana (the common footman), *L. quadra (the four-spotted 

 footman), *Gn6phria rubricollis. 



Amongst the ^octiddce, * Semiophora gothica, t Orthosis instabilis, *0. 

 gracilis, *0. munda, *0. criida, *0. stabilis, *Glae'a satellitia, fAmphipyra 

 pyramidea, fXylina rhizolitha, *X. petrificata, *Miselia aprilina (the beau-

 Orion, *D. ludifica (British ?) fCeropacha diluta, f C. ridens, f Cymatophora 

 O^o, *C6smia trapezina, -)-Xanthia croceago, and fX. rufina, fCatephia 

 leucomelas, *Catocala fraxini (the great blue under-wing moth, similar to 

 C. elocata, p. 1484. fig. 1293., but 4 in. in expanse, and having the ground 

 of the under wings blue instead of red), f Catocala pacta, -f- C. sponsa, 

 and f C. promissa, three very beautiful, but small, species of this genus, with 

 the ground colour of the under wings scarlet), and *Brepha notha. 



Amongst the Geomctridce are, f Anisopteryx leucophearia, *Hybernia capreo- 

 laria and *H. defoliaria (which are occasionally very destructive in oak copses), 

 ♦Phigalia pilosaria, *BIst07j prodromarius (the great oak beauty), * B. betu- 

 larius (the peppered moth), * Himera pennaria, * Crocalis elinguaria, several 

 species of thorn moths (sevej-al of which are figured in all their states, and 

 in a most admirable manner, by M. Lyonnet, in his Posthumous MemoirSy 

 recently published), including t Georaetra quercinaria, \ G. quercaria, f G. 

 anguliiria, *G. illunaria, * G. illustraria, &c. ; f Cleorrt bajularia, Cle6r« cinc- 

 taria. (See Mag. Nat. Hist., v. p. 265.) * A'lcis roboraria, A'Ici* consonaria, 

 and A. consortaria {Lyonnet Minn. Posth., pi. 29. f. 20 — 27.}, f E'phyra 

 punctiiria, * Eurymene dolabraria. Amongst the Platyptermdce, VyrdlidcE, 

 TortricidcE, Tincklce, and other remaining lepidopterous families, composed 

 of insects of small size, a vast number of species are oak feeders, including 

 •Drepana falcataria, f D. hamula, *Pechipdgon barbalis, *Hyl6phila prasiniina 

 {Reaumur Mem., tom. ii. pi. 39. f. 13, 14.), * H. quercana, f Lozots^nia robo- 

 rana, f Pseudotomia atroniargiina, *Roxan« arcuana, f Phibalocera quercana, 

 f Phycitaroborella, Adela Geevet/a {Lyonnet Mem. Posth., pi. 1 9. f. 17 — 25.; 

 Tinea sequcUa {Id., pi. 19. f. 26.), the cocoon of which is an exceedingly 

 interesting geometrical construction, described in detail by Lyonnet. 



Amongst the Leaf-feeding SjJeeies, the majority are external feeders, neither 

 concealing themselves in cases, nor rolling themselves up in leaves ; but some, 

 especially amongst the smaller species, do not agree with these in their habits, 

 and adopt various methods of defence, which render an examination of the 

 different inhabitants of this tree an object of the greatest interest. Of these 

 some roll up several leaves into a ball of considerable size {Rcaum. Mem., tom. i. 

 pi. 15. f 3., and pi. 32. f 4, 5.), which latter represents the habitations of 

 the scarlet under-wing moths above mentioned ; others, again, construct their 

 boat-shaped cocoons of strips of oak leaves {Ibid., pi. 38. fig. 7.) ; others, 

 again, roll up the leaves in various directions (as J'ortrix viridana, above men- 

 tioned, p. 1818.; lieaum., tom. ii. pi. 13, 14, 15, 16.); others feed upon the 

 parenchyma of the leaf, raising, as it were, large circular blisters, the upper 

 and under surfaces of the leaf remaining unconsumed. {licaum., tom. iii. pi. 3.) 

 Some form tortuous labyrinths within the leaf, similar to those of the rose- 

 leaf miners ; and some live in little cases of leaves, or silk, which they carry- 

 about with them. {Reaiim., tom. iii. pi. 7.) 



Amongst the Coleopterous Inseets, the common cockchafer (^carabas'us 

 il/elolontha Lin.,Me\o\6ntha vulgaris Fab., fig. 1648. «), is the most obnoxious 

 of the leaf-eating species. The egg of this terrible devastator is white, and is 

 depo&ited in the groimd, where it soon changes into a soft whitish grab with
