Oulton Broad {Donisthorpe). and Devon {Keys, who also found the 

 larva), and I took it in Cornwall myself this year. 



Medon castaneus, Gr. — Mr. Walker first took this species in 

 moles' nests in a sandy place near Oxford, and it is probahle that it 

 will be found in other sandy districts. Mr. Chitty bred one out of a 

 nest from Mickleham, and Mr. Champion has taken it in some 

 numbers at "Woking. 



Hister marginattjs, Er.— In January, 1907, I captured a single 

 specimen of this species in a leaf-nest near Bradfield, and subse- 

 quently found it rather commonly both here and at Bournemouth, 

 and took two specimens in Boss-shire. It has also been taken at 

 Woking {Champion), Oxford {Walker), Huntingfield, Kent, and 

 Cobham, Surrey {Chitty), Oulton Broad {Donisthorpe), and Devon 

 {Keys). 



I have little to add to my notes on the species in group B. : — 

 Bythinus securiger, Beich., does not appear to have been found by 

 other collectors, but probably only because sedge-nests have not been 

 very carefully sifted. Neuraphes rubicundus, Schaum, I have taken 

 on several occasions. Several species of ChoJeva occur commonly in 

 the nests and no doubt breed there, as I have found immature speci- 

 mens of various species : C. morio, F., I still think is the most 

 characteristic, the others being C. angustata, F., C. cisteloides, Frohl., 

 C. agilis, III., and C. nigrita, Er. I find that the Ptenidiitm, so com- 

 monly found, especially in sedge-nests, is P. atomaroides, Mots., not 

 P. evanescens, Marsh., as recorded by me. Oxytelus fairinairei, Pand., 

 is the most interesting addition to this group, and has occurred at 

 Oxford and Bradfield. Ilomalota ravilla, Er., and Aleochara succicola, 

 Th., should certainly be included here,£but it is probable that Ontho- 

 philus qlobulosus, 01., recorded by Mr. Bedwell, was only attracted by 

 the abnormal foulness of the nest, moles' nests being always quite 

 " sweet." 0. globulosus is undoubtedly a subterranean species. 



I have collected at various times a few other insects, wood- 

 lice, &c, from moles' nests, and Mr. Donisthorpe has very kindly had 

 several of these named for me by specialists, but nothing of great 

 interest has turned up. I prefer to leave these to be dealt with more 

 fully than I could expect to do by these specialists at some later date. 

 I have, however, carefully collected the fleas that are found so com- 

 monly in the nests, and Mr. N. C. Rothschild has identified 

 the following six species for me: — Ceratophyllus gallince, Schrk.
