132 THE ENTOMOLOGIST. 



P. ferrugana, Tr. — Common as this little species is in many places, 

 it certainly cannot be called so in South Essex ; indeed, I was 

 collecting several seasons before I met with it at all ! I have since 

 found the larva sparingly on birch at Loughton, Warley, and Ingate- 

 stone. I have bred from them vars. tripunctata, riifana, Hb., and 

 gnomana, Haw. 



P. aspersana, Hb. — Decidedly local, but found in several places, 

 of which I may mention Loughton, Upminster, and Woodford Bridge. 

 In addition to its two usual food-plants, Spircea filipendula and 

 Poterium satigaisoiba, I have found the larvae on Potentilla anserina 

 and P. tormentilla. 



Phhacodia candana, Hb. — Well distributed, but never very common, 

 perhaps more common in the Brentwood district ; I have beaten the 

 pretty variety ochracea, St., from poplar at Warley, and the type 

 generally from sallow and alder. 



Teras contaminana, Hb. — Often in hundreds, and in every variety 

 in hedgerows and whitethorn bushes ; some of the forms are very 

 bright and pretty. I have bred it from larvae feeding on flowers as 

 well as leaves of whitethorn. 



Bictyopteryx Iceflingiana, L. — Very common together with the vars. 

 plumbana, Hb., and ectypana on oak trunks, and may be beaten freely 

 from the boughs of the same wherever I have collected in the county. 

 D. holmiana, L. — Not very common ; may be beaten early in 

 August from hedges, especially those which contain a good quantity 

 of brambles, on which the larva feeds. 



D. bergmanniana, L. — Very common everywhere amongst wild 

 and, to a lesser extent, cultivated roses ; the larva in folded leaves of 

 the same. 



D. forskaleana, L. — Common everywhere amongst sycamore and 

 maple, on which the larva feeds. May often be beaten out in large 

 numbers from these two trees. 



Argyrotoxa comvayana, St. — Generally common, together with the 

 var. mhaurantiana, amongst privet, on which the larva is said to feed, 

 but I have never bred it. 



A. audouinana, Dup. — Local and rare. I have beaten out from 

 oak (usually) a very few specimens at Loughton about the third week 

 in June. Not met with elsewhere. 



Ptycholoma leacheana, L. — In great abundance among oak, flying 

 swiftly round the branches in the early evening. The pupa very com- 

 mon in the crevices of the oak bark, spun up in a white web. 



Ditula hartmanniana, L. — Local, and by no means abundant where 

 it does occur. By the Eiver Lea in one or two places, at rest on 

 young willow trunks. Much more abundant formerly, before so many 

 of the willows on the banks of the river were destroyed. 



D. semifasciana, Haw. — Another local species. I have found the 

 larvae on sallow bushes near Warley, and beaten the imago from the 

 same. Not met with elsewhere. 



Pentliiiia corticana, Hb. — Rather local, but not uncommon amongst 

 its food-plant, birch. May be often found at rest on the trunks, but 

 requires rather a sharp eye to detect it, owing to its colours matching 

 the colour of the trunk. Brentwood, Warley, Ingatestone, Ongar, 

 Wanstead Park, &c.
