LEPIDOPTERA NOTES FOR 1952. T w o new species were added to the Suffolk list. These were Orthosia advena, Schiff. (opima, Hbn.) and Semiothisa alternata, Schiff. Both these species were taken in a period of five minutes on May 3rd in our Mercury vapour trap situated in our garden at Needham Market. This trap is very badly sited, since the garden is almost surrounded by tall buildings with granaries 30 to 50 ft. high towards the east, while there are four massive beech trees in the western quarter, houses towards the south-east with the garden backed by further tall buildings. In the northern direction there is the only real gap over the railway embankment at the foot of the adjacent garden, but owing to the buildings the gap is 70 yards away from the trap. T h e attraction of the light trap would, therefore, seem to be upwards and by light reflected from the building. T h e number and variety of species has been amazing considering the restriction imposed by the site. These results, we suggest, are due to the following causes :— (1) T h e light being used on most nights, thus attracting those species which only fly for a few nights. (2) T h e increased light spectrum and upward field of light attracting those species which are moving at higher levels than usually covered by traps. (3) Certain species away from their usual habitat and breeding on built-up areas would be less subject to attacks from the customary parasites, thus resulting in local increase in numbers. (4) T h e railway may be responsible for the introduction of species new to the locality. T h e following are among the more notable species taken at this trap during 1952 :— Phragmatobia fuliginosa, Linn. ; Cycnia mendica, Clerck., one on April 26th ; Arctia villica, Linn. ; Roeselia confusalis, H.-S., one on May 19th ; Earias clorana, Linn., June 30th ; Pseudoips bicolorana, Fuesll., two on June 30th ; Bena prasinana, Linn., Apatele leporitia, Linn., June 25th and 30th ; A. aceris, Linn, two on July 22nd and 24th ; Cratiiophora ligustri, Schiff., June 3 0 t h ; Nonagria geminipuncta, Hatch., August 13th; Cosmia pyralina, Schiff., July 2 0 t h ; C. diffinis, Linn., August 12th; Hydraecia petasitis, Doubleday, August 15th ; Caradrina ambigua, Schiff., one on May 26th ; Eremobia ochroleuca, Schiff., common, Heliothis dipsacea, Linn., July 2nd and August 12th ; Agrotis clavis, Huf.
