PTEROMALIDAE OF N.W. EUROPE 143 



Cyrtogaster tenuis Walker. One $, designated LECTOTYPE (but possibly 

 holotype), bearing a Waterhouse label ; it is a small specimen of vulgaris. Placed 

 in synonymy with vulgaris by Askew (1965 : 180). 



Cyrtogaster cingulipes Walker. One $, LECTOTYPE (possibly holotype), bearing 

 a Waterhouse label. 



Cyrtogaster poesos Walker. Type not located. 



Lamprotatus acarnas Walker. One $, LECTOTYPE, bearing a Waterhouse label. 



The types of Dicormus aquisgranensis Forster and Cyrtogaster biglobus Forster 

 have not been examined by me. These species were placed in synonymy with 

 vulgaris by Delucchi (1955a : 174-5) and I accepted his opinion. 



Sphegigaster degener Walker. One ?, LECTOTYPE, labelled " Madeira Is. 

 Northern Dezerta Wollaston " and (in Walker's handwriting) " Sphegigaster degener". 

 It is the form with red legs. 



Cyrtogaster scotica Walker (1833 : 382, $) was placed in synonymy with vulgaris 

 by Askew (1965 : 180-181). I doubt whether this synonymy is correct. Walker's 

 description (1833 : 382-3) includes the statement " pedes fusci, tibiis apice tarsisque 

 nigris " and I have not seen any female Cyrtogaster in which the tibiae are darker at 

 their apices than elsewhere. There is no specimen in Walker's collection under the 

 name Cyrtogaster scotica ; but I have found elsewhere a female which may be the 

 type (see below under Seladerma tar sale). 



Widely distributed and very common in Europe. Females may be found in every 

 month of the year ; they pass the winter concealed amongst the foliage of coniferous 

 trees, Buxus, in debris lodged between sprouts on the boles of oak-trees, in haystacks 

 and similar situations. 



Biology. Several Agromyzidae are recorded as hosts ; see Askew (1965 : 185- 

 186). I have also examined specimens reared from Phytomyza atricornis Mg. on 

 Aster sp., from Phytomyza crassiseta Zett. on Veronica officinalis L., and from 

 Phytobia sonderupi Her. on Carex sp. (material reared in England (G. C. D. Griffiths) 

 and now in BM(NH)). Flies belonging to Chloropidae and Lonchopteridae have 

 also been cited as hosts ; these records need confirmation.

 paratypes in the Manchester Museum and in my own collection.

 and March (probably hibernating specimens).
