The LiPAHiDiE furnish three genera and eight species, viz., 

 Leucoma, three; Ocneria, one (obtained from chrysalides at 

 Ardrossan) ; Porthesia, four. 



The Cossim: supply the largest moths in the Province, one 

 species of Cossus, Fabr., exceeds seven inches in span, and two 

 or three others approach it in size. The larva? of these inhabit 

 the trunks and main branches of divers Eucalypts, drilling 

 circular holes about three-quarters of an inch in diameter 

 through the sound timber. Eight species are in the collection. 



Of the allied Zeuzera, Latr., one specimen was taken at 

 Ardrossan. 



The family of the Cocliopod^, of which the caterpillar 

 forms hard, egg-shaped cases for the chrysalis, the latter de- 

 veloping its limbs in distinct and separated casings, the genus 

 Limatodes, Latr., exhibits one, and Promecoderis three species. 

 The HEPiALma; furnish four species in one genus. Psychid^i 

 are numerous ; the genus Psyche, Schr., containing five, and 

 Oreopsyclie, Sp., seven species. The caterpillars of this family 

 form for themselves a dwelling, consisting of a silky bag over- 

 laid with little sticks, &c, in which also the chyrsalis state is 

 passed. Woods mentions the largest of these bag-bearers 

 under the generic name Oiketicus, I believe. The SATrpxin^ 

 seem scarce, only three species having been found, representing 

 as many genera,' viz., Endromis, Ochs. ; Satumia, Schr. ; and 

 Attacus. The latter exceeds three inches in span. Its cater- 

 pillar is of a green colour, and feeds on the leaves of Eucalyptus 

 riminalis, forming an oval cocoon of dark-grey silk one inch in 

 length. 



Gastropaclia is represented by seven species, two of which 

 form the bright green silky cocoons found suspended among 

 the leafy tops of Eucalypts. Eriogaster, Grerm., contains three. 

 Of the JsoTODOXTiDiE f our species occur, seemingly of the genus 

 Cnetocampa, Steph., the caterpillars of which live and feed in 

 great societies, marching out in procession. They pass the 

 chrysalis state either under loose bark or in large nest-like 

 structures among the smaller branches — (a social spider mimics 

 them) — of the trees on which they feed. Great damage is 

 sometimes done by them. 



Ctmatophora, Tr., furnishes four species, and forms the con- 

 necting link between the foregoing and the Noctuadce proper. 

 The latter are rich in species, but often scarcely separable. 

 Among them the following appear, viz. — Pcmihea, Hiibn, 

 (Bombix, Latr.), with four ; Bryopliila, with one species ; 

 Leiicania contains seven, mostly numerous ; Tryphaena, Hiibn, 

 three (all rare) ; Agrotis, Ochs., fifteen ; Episema, Ochs., ten 

 species ; all of the last genus are very active moths, flying in 

 the glaring daylight of spring and summer.
