A HISTORY OF SURREY 



Of the Rhyacophilidae, Rhyacopbila dorsalis, Curt., is recorded from 

 Haslemere, and is common at swift parts of a brook near Surbiton ; 

 Agapetus comatus, Pict., from Ripley commonly ; A. fuscipes, Curt., from 

 Ripley, Send and the White Falls Leatherhead. 



The Hydroptilid<z are only represented by Hydroptila sparsa, Curt., 

 from the river Mole near Box Hill ; by Ithytrichia lamellaris, Eaton, from 

 Weybridge ; and by Orthotricbia angustella, McLach., from Kingston-on- 

 Thames. 



HYMENOPTERA ACULEATA 



Bees, Wasps, Ants, etc. 



This section of the Hymenoptera is exceedingly well represented in 

 Surrey, 312 species being recorded out of the 384 which have hitherto 

 occurred in Britain ; of these, three species have up to the present been 

 recorded from this county only : Psen concolor, Dhlb. ; Crabro scutellatus, 

 Schev. ; Crabro clypeatus, Linn. ; but in all probability they are not 

 peculiar to Surrey, and will occur elsewhere, as other counties are more 

 thoroughly worked. Surrey has perhaps had more attention paid to it 

 entomologically than most counties, as many of its best localities are 

 within easy reach of London, and have been the favourite hunting-grounds 

 of entomologists for many years. The Bagshot Sands districts have been 

 especially well worked, and curiously enough all the three species so far 

 peculiar to the county are from localities on this formation. Four or 

 five years ago several other species had Surrey records only, but they 

 have been discovered elsewhere. Pompilus minutulus, for instance, which 

 one might quite have expected to be peculiar at least to sandy localities, 

 has been found in the chalky district of St. Margaret's Bay in Kent. 

 In fact, in the present state of our knowledge, it is very dangerous to 

 attempt to limit the distribution of the species of this order, and there 

 is no doubt that it is much more general than in such orders as Coleoptera 

 and Hemiptera, as may be inferred from the larger proportion of this order 

 found in Surrey, though the collectors of Coleoptera and Hemiptera are 

 more numerous than those of the Hymenoptera. 



The Ghrysididez are added to this section as a supplement by the 

 Rev. F. D. Morice, as although they are not generally included in the 

 Aculeata they are more closely allied to them than to any other group.
