 The three speeies have a eonsiderable resemblance in 

 form and colour. D. plumbeo-niger may be known by its 

 coneolorous antennae and legs. The males of D. oculatiis 

 are distinguished by the large globose eyes, the space 

 between w4iieh is much narrower than in D. plumbeus : the 

 females are more difficult, but in D. oculatus the base of the 

 antennae and the anterior coxae are testaceous, while in D. 

 plumbeus only the second joint of the antennae is testaceous, 

 and the eyes are less developed in the latter species. I have 

 received from M. Eichoff specimens of D. aerosus, Kies., 

 which agree perfectly with the common English speeies, 

 aeratus, *S'^6'), which, however, will take Goeze's name, plumbeo- 

 niger ; Kiesenwetter appears formerly to have confounded it 

 with D. plumbeus. The range of the three species in England 

 requires further observation ; my specimens of D. oculatus 

 are all from Mr. WoUaston, who found them in Lincolnshire, 

 while my D. plumbeus are from the neighbourhood of 

 London. It seems very probable that more species of the 

 genus Dasytes will occur in England ; D. obscurus, Gyll., 

 can hardly be wanting, and the true D. subaeneus may be 

 confidently expected, and may at once be known by its 

 tarsi, which exceed the tibiae in length." 



New British Beetle.— Mr. G. R. Crotch sent for exhibition 

 Trachyphloeus laticollis {Schonherr, vii. 118), a beetle new 

 to the British list ; five specimens had been captured some 

 years ago at Weston-super-Mare. He considered the T. 

 anoplus of Forster, and the T. rectus and spinimanus of 

 Thomson, to be synonymous with T. laticollis, which ought 

 to be placed with T. alternans, spinimanus and scabriuseulus, 

 being nearest the former by the weak armature of the tibiae : 

 the comparatively dense setae separate it from T. alternans 

 and also from T. spinimanus.

Economy of Argiolus. — I want to know something more 

 kbout the holly blue (Lycaena Argiolus) : it is quite abundant 

 this year all over the place ; we always get it, but I have
