118 THE ENTOMOLOGIST. 



Norfolk example of Heliothis scutosa was bought for 22/-, and a hybrid 

 A. prodromuria-hetulana for the same sum. 



A pair of Nyssla lapponaria went for 16/-, and a pair of Cleora 

 angularia [viduaria) made £2. Among a few varieties of Abraxas 

 (jiossulariata was one of var. varleyata, which realized 32/6. A speci- 

 men of Sterrha sacrana, taken at Dulwich (G. G. B.), produced 16/-. 

 Three specimens of Lyijris [Cidana) reticulata, put up together, brought 

 in 30/-. Fine examples of Phibalapteryx polyyrammata sold for 22/- ; 

 and two lots of Eupithecia consignata, ten specimens in each, yielded 

 12/- and 20/- per lot. 



CAPTURES AND FIELD REPORTS. 



Vanessa antiopa in Cambridgeshire. — A specimen (recorded in the 

 * Field,' April 7th) was seen at Little Shelford, on April 3rd, by Mr. 

 G. F. 0. Bagnall, which settled by the roadside, but it evaded his 

 attempt to capture it. — F. W. F. 



Orobena straminalis in Surrey. — In turning over the 'Entomo- 

 logist' for 1904, I came across Mr. South's note on Surrey localities 

 for this insect. I took six or eight specimens last summer near Bletch- 

 worth.— H. V. Plum ; Epsom College, March 9th, 1906. 



EuGONiA (Vanessa) polychloros. — I should very much like to 

 know what has been other people's recent experience of E. polychloros 

 in this country. When I was a child, and for many years afterwards, 

 it was common hereabouts ; then it disappeared entirely for several 

 years, and I shall never forget my pleasure at once more seeing 

 hybernated specimens in Harington Hall Wood after its long absence. 

 Soon afterwards it gradually became common again, and was to be met 

 with in all directions until 1901. In that year it was so excessively 

 abundant in North Essex and on the Suffolk side of the River Stour 

 that I could have taken hundreds of broods had I required them. 

 They were so abundant on elm trees in Colchester as to cause people 

 to take steps to destroy them, under the delusion that they were likely 

 to prove exceedingly injurious, and I saw one very tall elm hedge 

 in the outskirts of the town which, for a considerable distance, was 

 entirely defoliated by them. But, strange to say, I only saw two or 

 three of the perfect insects later in the year, and from that time 

 to this not a smgle specimen has appeared, either in the spring or late 

 summer. How is this to be accounted for? My own theory is that 

 all the specimens which emerged in 1901 at once emigrated, that the 

 species is practically extinct here now, and that it is quite uncertain 

 wnen a fresh lot of immigrants will appear and repopulate the 

 district, though this may happen any season. I have noticed that 

 certain of the " agricultural entomologists " have continued to offer 

 the larvae at quite nominal prices, but whether they have been able to 

 supply them 1 do not know. It would be singular if the exodus of the 

 species from this part of England was due to conditions which have 

 not operated in a similar manner elsewhere. — W. H. Harwood; 

 Colchester, April 17th, 1906.
