Say, belonging to the family Lymexylida^, of which no repre- 

 sentative had previously been recorded within our district. 



On referring to Henshaw's check-list of N. A. Coleoptera 

 it appears that there are still thirteen families of which no 

 examples have yet been captured here. Several of these fami- 

 lies are, however, represented by single species, and altogether 

 furnish only about thirty forms. Many of these are southern or 

 western, but a few may be found to occur here if collecting is 

 carefully continued. Unfortunately at present the collectors are 

 few in number, and unable throughout the season to devote to 

 collecting the time necessary to assure the capture of species 

 which may occur only for brief periods, or in very small num- 

 bers. Mr. Simpson last summer collected assiduously at King's 

 Mere, and was rewarded by many fine species, such as the 

 beautiful longicorns Purpitricenus hurneralis Fab. and Antho- 

 philax malachiticus Hald. He obtained also additional speci- 

 mens of the interesting and somewhat rare staphylinid, LoinecJuisa 

 cava Lee, a dweller in ants' nests, and many other members of 

 the same family, of which some have been determined by Mr. 

 Wickham, and several additions thereby made to our lists. 

 Many undetermined species in nearly all families are still in our 

 collections, and there still remains plenty of work for local 

 Coleopterists. 



Among the eminent entomologists who for many years 

 rendered invaluable assistance, none did so more willingly or 

 more painstakingly than Dr. John Hamilton, of Allegheny, Pa., 

 who recently died in Florida. He was one of the foremost of 

 American Coleopterists and the author of numerous valuable 

 contributions to the leading entomological publications. Many 

 of these dealt with Canadian insects, and special attention was 

 given by him to the geographical distribution of northern 

 species. He was also a very careful and industrious collector 

 as is well evidenced by almost his latest production, a Catalogue
