Exhibitions. 



^ Mr. S. Stevens exhibited Molums Bartolemi, Ceratonhina Derbyana, Teffliis 

 Delagoigii, and other Coleoptera collected, by Mr. R. W. Plant, to the north of Natal, 

 towards Delagorge Bay, a locality previously unexplored by him ; also a living speci- 

 men of Trichius variabilis, which he had lately bred after remaining three years in 

 the larva state, subsisting on the living wood of the oat. 



Mr. Douglas exhibited specimens of Stenolophus elegans taken near Southend, 

 and observed that Dr. Power and himself had, on one of the recent hot days, obtained 

 upwards of sixty specimens of this hitherto rare species by searching in the wet mud ; 

 he also exhibited Trinodes hirtus lately bred from a rotten tree in Richmond Park. 



Mr. Janson exhibited several species of Coleoptera taken near the metropolis 

 during the past month, and made the following remarks respecting them : — 



" 1. LcemophlcBus Clematidis, Eric, found near Gravesend, Kent, in dead stems of 

 the traveller's joy {Clematis Vitalba). This species is now for the first lime intro- 

 duced into the British list. Mr. Wollastou, however, informs me that he some years 

 since detected an individual among sundry insects purchased by him at the sale of the 

 late Mr. Spry's collection, but, as that gentleman had incorporated many continental 

 specimens with his British insects, he considered it inexpedient to announce the 

 indigenousness of the species upon the bare evidence of the individual in question. 

 It is probable that this insect should be sought for in the month of May, or perhaps 

 even earlier, as three out of the five specimens now exhibited were dead, dry, and con- 

 siderably mutilated when found. The species was first taken by Mr. J. S. Baly, and 

 subsequently by myself. 



" 2. Lathrohium rujipenne, Gyll., Eric. Apparently of rare occurrence in Britain. 

 Mr. Stephens's descriptions (Illustr. Mand. v. 268, 6 ; Manual, 405, 3229) refer indu- 

 bitably to this species, being copied, the diagnosis verbatim, from Gyllenhal, but in 

 his cabinet a male individual of the common L. elongalum has served to represent it. 

 Mr. Waterhouse captured a single example, in the immediate vicinity of London, in 

 the summer of 1854, and I found two among various Brachelytra kindly presented to 

 me by Mr. S. Barton, of Bristol, by whom they were taken near that town. The spe- 

 cimens now before the Meeting I found at the roots of rushes, amongst moss, at the 

 side of a marsh near Gravesend. 



" 3. Plinthus caliginosus, F. Taken beneath a heap of decaying potato-haulm on 

 a hedge-bank at Darenth, Kent. This insect is probably more widely distributed over 

 the southern portion of our island than we had hitherto supposed. The present is not 

 the first instance of its occurrence in the vicinity of London: Mr. S. Stevens has 

 secured a specimen near Wickham, Surrey. 



" 4. Pseudopsis sulcatus, Newm. A single individual, taken by Mr. Francis 

 Walker in the Isle of Wight, about the year 1833, and from which Mr. Newman 

 drew up his generic and specific characters (Ent. Mag. ii. 313), was, I believe, the sole 

 English representative of this curious species until the autumn of last year, when Mr, 

 Waterhouse captured a specimen flying at dusk near a manure heap. In the interim, 

 however, Mr. Haliday met with it, in Ireland, by brushing herbage in the vicinity of 

 hay-stacks, and to that gentleman's liberality our principal collections have been long 

 indebted for specimens. The three individuals now exhibited I found near Dorking, 

 Surrey, in a boletus on the decaying stump of a felled tree.
