1914 -] 245 



C. mutabilis, Fin. : A rather small and dark $ on July 25th, near 

 Savernake Forest. 



Ischyrosyrphus laternarius, Miiller : This was quite common during July on 

 TJmbelliferaz in the same locality in which Stratiomys potamida, Mg. occurred. 



Platychirus fulviventris, Meig. : Not at all uncommon in June and July in 

 the marsh at Chilton Foliat, but exceedingly local. 



Syrphus lunulatus, Meig. : 1 ?, 26.5.14, Henswood ; 1 $, 10.6.14, Savernake. 

 This species is not generally common in the south of England, though more 

 frequent in the north. 



S. nigricornis, VeiT. : 1 <$ , 1.6.14, West "Woods; the specimen was hovering 

 over Ranunculus. 



S. diaphanus, Zett. : 1 $ on the 9th of July, in Stype Wood ; another $? on 

 the 20th of July, near Marlborough. Both were on Umbelliferw ; the latter 

 specimen along with hundreds of S. ribesii and S. vitripennis, among which more 

 examples of this interesting Syrphid may very probably have escaped my notice. 



S. labiatarum, Verr. : the females were not very uncommon on Umbelliferse, 

 but I only took one male. 



S. umbellatarum, Fab. : 3 ? , 4 — 15.7.14. These- three specimens, which 

 came from the same locality near Marlborough, though having a brightly 

 shining thorax, differ fx'om the ordinary $ S. umbellatarum, by having those 

 parts of the frons which are as a rule purplish or blue, shining black. 



Volucella bombylans Jj.: 2 beautiful $ $ of Zetterstedt's var. hsemorrhoidalis, 

 var. b, on June 19th and July 6th. 



Merodon equestris, F., var. narcissi, F. : 1 $ of this form at Manningford, 

 13.6.14. There is a small bulb-farm not far distant. 



Helophilus frutetorum, Fab. .- 1 $ , 1 2 , on the blossoms of Bhamnus cath- 

 aHicus, 2 and 14.6.14, Marlborough. It occurred together with the somewhat 

 commoner H. versicolor. 



Criorrhina floccosa, Meig. : 1 $ , 12.6.14, West Woods, where I have also 

 taken C. oxyacanthx and C. asilica ; all three species on the blossoms of Eubus. 



Exorista vetula, Meig. : 2.5.14, West Woods. 



Hyetodesia variegata, Meig. : 9.5.14, near Marlborough. 



Rhacochlsena toxoneura, Lw. : 1.6.14, West Woods ; 1 $ , on Salix. 



The capture of 2 $ ? of Chrysotoxum odomacidatum, Curtis, at 

 Chippenham Fen, Cambridgeshire, on July 28th, may also be worth 

 recording, as this is, I believe, quite a new locality for this species. 



The Deanery, Ely : 



September, 1914.
