COLEOPTERA OCCURRINa IN THE NESTS OF MAMMALS 

 AND BIRDS. 



BY NORMAN H. JOY, M.E C.S., F.E.S.

Bythinus securtger, Reich. -This is the first species of my 

 Class B. It occurs rarely by sweeping and in moss, dead leaves, &c., 

 but I have taken it on several occasions here (about 60 specimens 

 altogether) in moles' nests made of sedge, and there were several 

 specimens in some nests kindly sent to me by a friend from Wells, 

 Norfolk. The S^ ^'^^ich is always looked upon as a great rarity, has 

 turned up twice. The enlarged last joint of the maxillary palpi 

 varies much in shape and length, and I thought at one time that the 

 extreme forms were two allied species, but I have now all the inter- 

 mediate forms. 



Choleva morio, F., is not uncommon in sedgy and marshy places 

 generally, but I have found it in moles' nests on dry hill-sides, and it 

 is by far the commonest species of the genus that occurs in the nests. 

 Ptenidium evanescens. Marsh, is often found in large numbers 

 in the nests, many specimens being quite immature, but of course it 

 is a common species generally. 



Epur^a iESTiYA, L , and E. melina, Er , I have taken in three 

 or four nests, and in two the larvse of the latter was present in num- 

 bers. These species also often occur in humble-bees' nests. 



EuPLECTUs siGNATUS, Rcich., and Ephistemus globosus, Waltl, 

 are 1 think more than accidental visitors, as I have found them not
