THE YOUNG NATURALIST. 



C. campestris. — Head, thorax, and elytra 

 green, the latter with four or five cream- 

 coloured spots. Common in sandy lanes. 

 The var. funeh'is, Stu., is described as 

 having the upper side entirely black. 



C. hylrida. — Head, thorax, and elytra 

 bronze, the latter with a cream-coloured 

 crescent at the shoulders, another at the 

 apex, and a transverse band of the same 

 colour in the middle, which runs slightly 

 backwards towards the suture and is a little 

 narrower in the middle. In the var. mari- 

 tima this band appears like two spots, one 

 at the middle of the side and one nearer the 

 apex on the disk of the elytra, the two spots 

 being connected by a very slender streak of 

 the same colour. The type form is very 

 abundant on sandhills on the coasts of 

 Lancashire, Cheshire, and North Wales ; 

 the variety (if variety it be) occurs plenti- 

 fully on the east coast, also in the south. 



C. sylvatica. — Head, thorax, and elytra 

 bronze, the latter with markings somewhat 

 like hydrida, but easily distinguished from 

 all the other British Cicindelae by its UacTt 

 Idbniin. Sandy heaths in the south of 

 England. 



G. germanica. — Dark green or blackish, 

 elytra with a white spot at the shoulder and 

 a white crescent at the apex. Occurs locally 

 in the Isle of Wight, &c. 



CARABID^. 

 Carahides. 



The British species belonging to this 

 group, which, as mentioned on page 13, are 

 easily distinguished from all other Carabidae 

 by the absence of the notch on the inner 

 side of the anterior tibiae, are now generally 

 arranged in the nine following genera, viz : 

 Notiojpldhis, Elcqjhrus, Bletldm^ Cychrus, 

 Carabus, Calosoma, JVehi'ia, lelojjMla, and 

 Zeistus, and these genera may be easily 

 separated from one another by the following 

 characters. It must be distinctly under- 

 stood that because we have endeavoured to 

 find the simplest (though perhaps the most 



artificial) means of separating genera and 

 species, we have done so with the idea of 

 assisting beginners to name their specimens, 

 and to create a taste for the study of the ■ I' 

 order by smoothing over difficulties as far ^ 

 as possible, and not with the idea of sup- 

 planting any reference to, or dissection of, ^ 

 the minute anatomy of the insect, on which ' 

 alone, generally, is based a true natural 

 classification. 



Notiophilus —This genus is distinguished 

 from all the other British Carabides by its ^ 

 small size (never measuring ^ inch) and by ' 

 the h^ad heing as wide as the elytra. The 

 species are of a shining bronze colour, with 

 prominent eyes, on the forehead between 

 which is a series of longitudinal furrows. 



Elaphrus — The species of this genus are 

 all a little over I inch in length ; bronze or 

 bronze-green in colour ; the head narrower 

 than the elytra ; the latter without rows of 

 punctures in striae, but with four rows of 

 circular degressions .eye spots or ocelli) ; 

 the eyes are prominent; the thorav as 

 long as broad. 



Blethisa. — Nearly half-an-inch in length ; 

 colour bronze-black ; eyes not very promi- 

 nent ; the elytra punctate-striate, with two 

 rows of dc])ressions ; the thorax broader than 

 long. 



Pelophila. — Nearly half-an-inch in length ; 

 colour bronze ; elytra very finely punctate- 

 striate, nvith one row of dejjressions ; thorax 

 twice as broad as long. 



Cychrus. — Length about f inch ; colour 

 black ; head very long ; thorax narrowed 

 behind, much narrower than the elytra, which 

 are ovate; anterior tarsi of males not dilated. 



Cardbus — Length from f to 1 4 inches ; 

 colours various ; thorax almost squa/re, sides 

 nearly straight ; elytra oblong-ovate : males 

 with anterior tarsi dilated. 



Calosoma. — Length from | to one inch ; 

 colours bronze or green ; thorax much 

 broader than long, sides much rounded; 

 elytra nearly square.
