86 BR. J. ENT. NAT. HIST., 7: 1994 



Since S. delicata was described, a second species, S. cogani, has been described 

 as new to science from Britain (Irwin, 1982). There are at least two further undescribed 

 species from Europe (J. Ismay, pers. comm.; Andersson, 1991). 



Parochthiphila coronata (Loew) (Chamaemyiidae) 



This species was swept in small numbers from short grassland at Blackburn Meadows 

 (also known as Tinsley Sewage Beds), Sheffield, South Yorks (SK4191 & SK4192) 

 on 29.vii.1991 and on 18.vii.1993. It was only previously recorded in Britain from 

 two localities on the coasts of Essex and Norfolk (McLean, 1980) and is accorded 

 Red Data Book Status 1 (Falk, 1991). The male genitalia were checked since there 

 are several further Parochthiphila species in Europe and the CIS, and because the 

 Sheffield specimens are the first inland records for this species in Britain (the species 

 occurs inland throughout the rest of the Palaearctic, however). Differences in 

 the genitalia were detected using the work by Tanasijtshuk (1986) but they are 

 very similar to the figures given by Raspi (1983). The ecology of P. coronata has 

 been described by these workers. The larvae have been recorded feeding on coccids 

 at the base of Elymus repens (L.) Desv. ex Nevski and Ammophila arenaria (L.) Link. 

 (Grasses from the exact site of the Tinsley specimens have been identified for me 

 by Mr Tim Smith and comprise Agrostis stolonifera L., Dactylis glomerata L., 

 Lolium perenne L., Holcus lanatus L. and Arrhenatherum elatius (L.) P. Beauv. ex 

 J. S. & C. Presl.) 



Pseudopomyza atrimana Frey (Pseudopomyzidae) 



A male of this species was taken by sweeping on a visit to Loch na Dal, Isle of 

 Skye (NG704160) on ll.vii.1991. This obscure fly has been given Red Data Book 

 Status 1 (Falk, 1991) and is the second (first male) British specimen. The species was 

 added to the British list by Chandler (1983) from a female taken in Kent in 1972. 

 The site is an area of open seepage with Sphagnum, Eriophorum, and Myrica 

 passing into birch and sallow woodland on a gentle slope at the head of the Loch. 

 Unfortunately it is not clear whether the fly came from the open area or from 

 the woodland. The fly was recognized as unusual when sorting out the catch in the 

 evening and it was subsequently identified as this, species by Dr John Ismay and 

 Peter Chandler. The genitalia compare well with that illustrated by Frey (1952) 

 and is illustrated in Fig. 1. 



Since Chandler (1983) published his record, the species 

 has also been recorded from Hungary (Soos & Papp, 

 1984) and a second record for Czechoslovakia has been 

 published (Frouz & Maca, 1985). 



Periscelis annulata (Fall.) (Periscelidae) 



A male was swept by my collecting partner, John 

 Mousley, from Ballinluig Shingle Island on the River Tay 

 near Pitlochry (NN9754) on 15. vi. 1992 and subsequently 

 passed to me in the evening along with other 'rubbish'. 



I — 1 This species like all periscelids is rarely recorded and it 



Fig. 1 . Pseudopomyza 1S currently regarded as notable by Falk (1991). The larvae 

 atrimana, posterior part of of the Periscelidae are associated with oozing tree sap (see, 

 male abdomen. Bar 1mm. for example, Papp, 1988).
