40 HYMENOPTERA. 



district ; the late Mr. W. Wing captured it on the ninth 

 of December. 



Myr.rn.ica nitidula, Nylander. This species was added 

 to the British List by Mr. G. R. Waterhouse, who found it 

 in the nests of Formica rufa ; it is readily distinguished 

 by being entirely smooth, shining, and destitute of pube- 

 scence. Nylander finds it in the nest of F. rufa and F. 

 congerens; it is singular that this species, and also Myr- 

 mica muscorum, an insect not yet found in this country, 

 appear always to establish their colonies in- the nests of 

 species of Formica ; we have little doubt, if our Cole- 

 opterists look carefully for minute ants when searching in 

 the nests of the wood ant, they will find the Myrmica 

 muscorum ; it is distinguished from M. nitidula by being 

 very pubescent. 



Fossores. 



Pompilus pectinipes. This species is not rare at Deal ; 

 we captured both sexes on the west side of the sand-hills, 

 opposite the first battery. 



Ammopkila lutaria. This species we took at the same 

 time and place as the former insect. 



Miscophus spurius ? Dahlb. Having discovered this 

 species last season to be an inhabitant of Great Britain, we 

 were anxious to obtain more specimens, in this we were not 

 disappointed ; both sexes occurred on the west side of the 

 sand-hills, about half-way between Sandown Castle and the 

 battery. 



Trypoxylon attenuatum. This species has been cap- 

 tured by Mr. Parfitt in Devon, and by myself at Reigate 

 Common. 



Astata hoops. This species was captured in June on 

 Reigate Common, a new locality for this very local insect. 



Crabro Lindenius, C. capitosus and C. hyalinus. Mr.
