MacrocJicBta davicornis, Sars, one of the Pisionidae, in St 

 Andrews Bay. This species is compared with a form 

 recently described by Mr Southern, from Clare Island, off 

 the west coast of Ireland, and placed by him in a new 

 genus called Praegeria. 



The paper on the Biology of Sewage Disposal, by J. W. 

 Haigh Johnson, alluded to in our December number, is now 

 concluded.^ The remaining sections are entitled : " Ecological 

 Associations and Distribution of Organisms on Sewage 

 Filters," *' Some Noteworthy Dominant Organisms occurring 

 on Sewage Filters," " Other Dominant or Sub-dominant 

 Organisms," and " Oxidation of Sewage without the Aid of 

 Filters." A short Summary and a full Bibliography complete 

 a memoir which we can cordially recommend to the notice 

 of our readers, for many details are given of interest to 

 specialists regarding the habits and life-histories of such 

 creatures as the " Sewage "- or " Moth-fly " {Psychoda) and 

 the " Water Springtail " {Achorutes viaticns), as well as 

 information on matters of a more general import. 



In a paper by Olga G. M. Payne, entitled " Notes on 

 TelepJiortis rufus, L., and its varieties," - an account is 

 given of the rearing of a number of these well-known 

 beetles from larvae obtained in a single field near the 

 Manchester University. From these larvae, which varied 

 much in colour, adults were obtained which were referred to 

 Messrs Sharp, Gahan, Halbert, and Hardy, all well-known 

 authorities on Coleoptera. Upon the strength of the replies 

 received from these experts the authoress expresses the 

 opinion that Telephoi'us lituratus, Fall., and T. darwinianiis^ 

 Sharp, should be regarded as varieties of T. rufus, L. This 

 is the more interesting to us since T. darivinianus is one of 

 our Scottish specialities, and pilgrimages have on many 

 occasions been made to Aberlady in pursuit of specimens. 



Our valued contributor, Mr Frank Balfour-Browne, whose 

 paper on the Water-beetles of the Outer Hebrides is now 

 appearing in our pages, is also publishing important articles
