Lake Nyassa {Mr. Cotterill) . 



A small narrow species resembling an Argutor. The thorax is 

 broader than long, with rounded sides, sinuated only just before the 

 slightly projecting hind angles. The lateral rim of the thorax is not 

 at all thickened, and its accompanying groove is of equal width 

 throughout, and delimited from the disc by a fine fold. The posterior 

 episterna are decidedly longer than broad.

ENTOMOLOGICAL LOCALITIES NEAE LIVERPOOL. 

 BT JOHN W. ELLIS, L.E.C.P., F.E.S. 



Some of the readers of the Ent. Mo. Mag. will, doubtless for 

 the first time, be visiting Liverpool dui'ing the ensuing two months, 

 attracted thither by the Liverpool Exhibition, and in the interest of 

 such strangers to the neighbourhood the following notes have been 

 penned as a " guide " to those localites within a moderate distance of the 

 city which are of interest to the practical entomologist. 



The geological formation upon which the city of Liverpool and 

 its immediate neighbourhood, both in Lancashire and Cheshire, rests, is 

 that of the trias or new red sandstone, the characters of which are 

 well shown in the cuttings leading to the Lime Street and central 

 railway stations, but above this rock there exists throughout the greater 

 portion of the district a layer, variable in depth, of cold, tenacious, 

 boulder clay, containing glacier-grooved stones and many species of 

 sea-shells almost, if not quite, identical with those at present living in 

 the Irish sea. As may be expected from a geological formation so 

 unproductive of peculiar forms of plants, the insects of the district 

 are not of a very striking character, except where the surface of the 

 country has undergone some departure from the ordinary condition, 

 such as has occurred in three distinct forms, viz : the tract of sand- 

 hills which stretches from the E-ibble to the Mersey (Lancashire), 

 and, again, from the Mersey to the Dee (Cheshire) ; the elevated 

 ground in that portion of Cheshire which lies between the rivers 

 Mersey and Dee, where the sandstone appears at the surface, without 

 any clay covering, and where the prevailing plants are the heaths and 

 gorse, such localities as Bidston and Prenton Hills ; and, thirdly, the 

 tracts of moss-land, fast alas ! disappearing through cultivation, parts 

 of the original Chat moss over which the railway is carried between 

 Manchester and Liverpool. These localities may now be treated 

 seriatim, only those insects being noticed which are of special interest.
