Poljjf/onia et/ea, Ci". Cramer figures a specimen with a dark band 

 and a white space beyond it, across the underside. Stichel devotes 

 a paragraph to this figure, concluding it is due to imperfect painting. 

 I must observe that in Italy specimens coming very near it do exist, 

 though they are rare. Esper's name van-albnin should, 1 think, be 

 used for the usual individual form with a more even pattern on that 

 surface.

Notes on Cemiostoma wailesella and other Lepidoptera in Sussex 



in 1919. 



By ALFEED SICH, F.E.S.- 



That vast collection of houses, known as Brighton, does not 

 provide for the wants of many species of Lepidoptera, but several of 

 those that may be classed as urban species do occur. The prevalent 

 plant is EuonyiiiHH japunica, which supports Abraxas (imsfiulariata in 

 abundance, and also Hyponomeuta cognateUns this year in less numbers. 

 Bryophila peiia is not rare in some of the side streets and m certain 

 suitable places along the front. Gypsonovia aceriana may also be seen 

 in the neighbourhood of poplars. Three specimens of 2'inea 2]allescen- 

 tella, quite a house-loving species, have been noted. Facing the sea at 

 Kemp Town is a bank of evergreens where Tortiix pronnbana has a 

 settlement, while Eucosma striana haunts the tennis courts above. In 

 June the town was invaded by a small army of Tortrix viridana, which 

 were, however, mostly white by the time they got here. They were to 

 be seen in the busy thoroughfares and one was found still alive at the 

 very end of the West Pier. In St. Ann's Well Gardens, Hove, a few 

 Gelechia rhoiiibella were observed partly hidden under flakes of bark on 

 apple stems, and later, on elm trunks after a wet and Avindy night, 

 several nice forms of Hypsilophtts vittella were taken, some ab. 

 ■carbonellvs and some approaching ab. fissella, while one or two were 

 very light grey. The cliffs between Black Eock and Eottingdean are 

 still fairly good, but a calm day is required for working there as they 

 are quite exposed to the wind. Thyme, Trefoil; and Centaurea are 

 perhaps the most attractive plants. In the middle of July Homoeosoma 

 sinuella was on the wing, flying up from the herbage whei;i disturbed 

 but soon settlmg again, and later Gracilaria tringipennella was common, 

 looking like a grey Coleophorid when in flight. One warm afternoon, 

 feeding on the patches of thyme, were many Coleophora lixella and C. 

 discordella, but examination of several of these failed to reveal two 

 other species which might have been among them. On another 

 occasion Cydia citrana was in good condition and easily walked up. 

 Some cocoons of a Bncculatrix were noticed on yarrow at the very 

 edge of the cliff, and remembering that a rare species was once bred 

 from this plant near the sea, I gathered them but they only yielded B. 

 cristatella. In August Laspeyresia ru/iUana was taken among wild 

 ■carrot, and an Elac/dsta atricomella was found. 



Earlier in the year Ciipido ininimiis was abundant in the sheltered 

 hollows on the cliffs between Rottingdean and Newhaven. On the 

 whole Rhopalocerahave not been much in evidence this year. On July 

 11th I went to Shoreham-by-Sea in the hopes of seing Lita instabilella 

 .alive. When I got out on the flats among the Atriplex I found I
