. 158 ENTOMOLOGIST'S RECORD, VOL. 103 21.v.1991 Apion modestum (formerly known as A. sicardi), was added to the British hst by M.G. Morris (1975, Entomologist's mon. Mag. Ill: 165-171), and according to Morris (1990, Handbk. Ident. Br. Insects, 5(16): 57), A. modestum has now been recorded from Dorset, S. Hants, W. Kent, Shropshire and South Wales. The weevil has not previously been recorded from West Cumbria and this is a new record for the county and the first for v.c.70, Cumberland. On 18th October 1990 I returned again to the Crossfield site and collected some seed pods ofLotus uliginosus. From one pod I obtained one more adult of A. modestum, which on dissection proved to be a male. Several other seed pods contained weevil pupae, all of which had been heavily parasitised; and one other pod contained four black, parasitic wasp — pupae. R.W.J.

Wooldridge brought me a geometrid moth which he had failed to identify, which he had taken at his actinic light trap at Niton on 12th October 1990. I confirmed this to be a specimen of Thera cupressata Geyer which was new to the Isle of Wight. This species is now established in the Channel Islands and from one locahty in Dorset and will probably extend its range along the south coast. On 18th October 1990 I took two specimens of Trigonophoraflammea Esp. at my mercury vapour light trap at Freshwater. This species has not been recorded from the Isle of Wight before and I took a third example on 20th October. It was also the largest influx of this migrant along the south coast in recent times. The 18th October was a night ofconsiderable migrant activity and I also took Heliothis armigera Hb., two Mythimna unipuncta Haw., three Mythimna albipuncta D. & S., one Agrotis ipsilon Hufn., two Autographa gamma Linn., two Peridromasaucia Hb., seven Palpita unionalisHb., one — Nomophiia noctuella D. & S., and two Udeaferrugalis Hb. S.A. Knill- JONES, Roundstone, 2 School Green Road, Freshwater, Isle ofWight. More on Cisfestivus Panz. and C. vestitus Mell. (Col.: Cisidae) I was interested to read the paper by my friend Mr A.A. Allen {Ent. Rec. 102: 177) dealing with this species pair for I have long had difficulty trying to separate these two species. After reading the note, I went through my relevant specimens again and, using the characteristics recommended in the paper, separated out four which appeared to befestivus. I was glad to have these determinations kindly confirmed by Mr Allen. I might add that two ofthese were in my collection as ''vestitus'' The field incidence of the two species in my experience is more or less as reported by my friend. Certainly, I have found/estivus much the rarer of the two, having come across only these four examples in the past 20 years.
