Cardiopboriis ; Cartliopborus fonnosus of Cmtis is pi-obably a variety 

 of C. 6-punctatus of llliger ; and finally, Aplotarsiis ? colburnatus of 

 Curtis is tbe Ampedus subcarinatus of Germar. Allbough no one 

 will attempt to deny tbe utility of pointing out errors sucb as appear 

 to exist in Mr. Curtis's contribution to our 'Transactions,' yet we 

 cannot but lament tbat Mr. Janson does not employ tbe great know- 

 ledge he appears to possess of our Elateridge in redescribing tbe spe- 

 cies and reforming tbe nomenclature of tbe entire group, ratber tban 

 in selecting, from wbat is probably amass of error, certainly to mode- 

 rate capacities a mass of confusion, a few examples of error or con- 

 fusion, tbe exposition of wbicb may possibly appear somewbat 

 invidious. 



The title of the very useful paper by Messrs. Waterbouse and 

 Janson is sufficiently explanatory — " On tbe British Species of tbe 

 Genus Stenus; with Notes on tbe Species of Stenus described by 

 Kirby, and in tbe Illustrations of British Entomology by Mr, Ste- 

 phens ^ together with Observations on tbe Specimens in Mr. Stephens' 

 collection." It is impossible to peruse this careful and laborious, but 

 most unpresuming contribution to Science, without experiencing 

 feelings of gratitude to the authors for the able manner in which their 

 task is performed, and also of the deepest regret tbat Mr. Kirby's 

 descriptions, written in the early part of tbe present century, were 

 never published : not only would they have proved a proud monument 

 to tbe author's genius and industry, and a rich boon to the student, 

 but, being long antecedent to the recent writers on the Staphylinina, 

 they would, as a matter of course, have saved us from that all but 

 inextricable confusion which entomologists are now so laboriously 

 attempting to unravel. This paper adds no less than twelve species 

 to our British Steni, all of them previously captured, but now for tbe 

 first time made known: these are as under: — Stenus aspbaltinus, 

 Erichson, found by Mr. Waterbouse in a chalk pit at Greenbithe, and 

 by Mr. Janson in a chalk pit at Charlton, in May. S. ater, Mdrnier- 

 heimy found at Greenbithe by Mr. Waterbouse, in June. S. morio, 

 Erichson ? a single specimen taken by Mr. Janson running on tbe 

 muddy bottom of a water-course in a wood near Highgate, on the 

 28th of August, 1854. S. incrassatus, Erichson, found by Mr. Water- 

 house on Wandsworth Common, in June ; and shaken from moss on 

 Wimbledon Common, in the winter. S. opacus, Erichson ; two spe- 

 cimens are in the cabinet of Mr. Waterbouse, which be believes were 

 taken in Northumberland. S. exiguus, Erichson, found by Mr. Wol- 

 laston at Spridlington, in Lincolnshire, and at Rosnalee, in the county
