As regards moths, several fresh species may be expected to appear, while those named as appearing in February are still to be found. The new-comers may include: =Bombyces.= Kentish Glory (_Versicolor_) Yellow-horned (_Flavicornis_) =Noctuae.= Pine Beauty (_Piniperda_) White-marked Rustic (_Leucographa_) Red Chestnut (_Rubricosa_) All species of the genus _Taeniocampa_ Early Grey (_Areola_) Green-brindled Dot (_Oleagina_) Orange Underwing (_Parthenias_) Light Orange Underwing (_Notha_) =Geometrae.= Early Thorn (_Bilunaria_) Engrailed (_Biundularia_) Mottled Grey (_Multistrigaria_) Sugaring may be commenced towards the end of March, and sallow blossom may be searched in the evening, but it is probable that only a few species will be taken by these means. A few more species of the _Tineae_ appear in March, and four or five of the _Tortrices_ are out before the end of the month. APRIL This is really a busy month with the entomologist, and it will be necessary to put all apparatus and appliances into perfect order early. The cyanide bottle should be freshly charged, nets examined and repaired if necessary, and all setting boards, breeding cages &c. put in perfect trim for the new season's work. Larvae are now feeding freely, and a few hours spent in beating, sweeping, and searching will enable you to stock your cages liberally. Sugaring may be continued throughout the month, and the sallow blossom may be searched as long as it proves attractive. Moths may also be attracted by light at night. The following butterflies are generally out during April, in addition to the hybernated species already named: Large White (_Brassicae_) Small White (_Rapae_) Green-veined White (_Napi_) Orange Tip (_Cardamines_) Wood White (_Sinapis_) Pearl-bordered Fritillary (_Euphrosyne_) Speckled Wood (_Egeria_) Green Hairstreak (_Rubi_) Small Copper (_Phl[oe]as_) Holly Blue (_Argiolus_) Grizzled Skipper (_Malvae_) Dingy Skipper (_Tages_) The following is a list of the principal moths for April: =Bombyces.= Small Lappet (_Ilicifolia_) Kentish Glory (_Versicolor_) Yellow Horned (_Flavicornis_) Frosted Green (_Ridens_) =Noctuae.= Pine Beauty (_Piniperda_) White-marked Rustic (_Leucographa_) Red Chestnut (_Rubricosa_) All species of the genus _Taeniocampa_ Early Grey (_Areola_) Mullein Shark (_Verbasci_) Orange Underwing (_Parthenias_) Light Orange Underwing (_Notha_)
