As regards the Micros, a good number of fresh species may be expected, all the groups exhibiting a marked increase in the total number on the wing with the exception of the _Tineae_. Sugaring is likely to pay well this month, and many moths may be attracted by light. Tree trunks and fences should be well examined. Pupae may certainly be taken, but unless the collector is particularly desirous of obtaining the pupae of insects known to be now passing through that stage, he will probably do better by looking after imagines. Larvae, however, may well receive a little attention, providing the setting of butterflies and moths leave a little leisure for other employments. Beating by day, and searching by both day and night, even if carried on only occasionally, will probably supply you with as many species as you can accommodate in your glasses and cages. The butterflies of the month are: Swallow Tail (_Machaon_) Black-veined White (_Crataegi_) Large White (_Brassicae_) Small White (_Rapae_) Green-veined White (_Napi_) Wood White (_Sinapis_) Brimstone (_Rhamni_) Dark Green Fritillary (_Aglaia_) High Brown Fritillary (_Adippe_) Silver-washed Fritillary (_Paphia_) Heath Fritillary (_Athalia_) Comma (_C-Album_) Large Tortoiseshell (_Polychloros_) Small Tortoiseshell (_Urticae_) Peacock (_Io_) Painted Lady (_Cardui_) White Admiral (_Sibylla_) Purple Emperor (_Iris_) Marbled White (_Galatea_) Northern Brown (_AEthiops_) Speckled Wood (_Egeria_) Grayling (_Semele_) Meadow Brown (_Ianira_) Large Heath (_Tithonus_) Ringlet (_Hyperanthes_) Marsh Ringlet (_Typhon_) Small Heath (_Pamphilus_) Brown Hairstreak (_Betulae_) White-letter Hairstreak (_W-Album_) Dark Hairstreak (_Pruni_) Purple Hairstreak (_Quercus_) Green Hairstreak (_Rubi_) Small Copper (_Phl[oe]as_) Silver-studded Blue (_AEgon_) Common Blue (_Icarus_) Chalk-hill Blue (_Corydon_) Holly Blue (_Argiolus_) Mazarine Blue (_Semiargus_) Small Blue (_Minima_) Large Blue (_Arion_) Small Skipper (_Thaumas_) New Small Skipper (_Lineola_) The moths of July include the following species: =Sphinges.= Privet Hawk (_Ligustri_) Bedstraw Hawk (_Galii_) Eyed Hawk (_Ocellatus_) Poplar Hawk (_Populi_) Humming Bird Hawk (_Stellatarum_) Hornet Clearwing of Poplar (_Apiformis_) Hornet Clearwing of Osier (_Crabroniformis_) Welsh Clearwing (_Scoliiformis_) Red-belted Clearwing (_Myopiformis_) Red-tipped Clearwing (_Formiciformis_) Six-belted Clearwing (_Ichneumoniformis_) Genus _Ino_ Burnets (_Trifolii_, _Lonicerae_ and _Filipendulae_)
