and not so gaily coloured or metallic, though equally 

 diurnal and attached to plants. 



Our largest species is Adimonia tanaceti, a dull black, 

 sluggish, thickly and coarsely punctured insect, found 

 on the wild tansy, especially in chalky places on the 

 south coast. It exhibits in a marked degree the pecu- 

 liarity of the family of being widest behind; and its 

 female has somewhat the distended appearance of Gas- 

 trophysa above mentioned, possessing, also, though in a 

 minor degree, Lina's evil habit of distilling and smelling. 

 Of the others in this genus, A. caprecB is exceedingly 

 common on osiers, and less so on heath, a very wide 

 range of food-plant, and, when feeding on the latter, 

 becomes of a much darker colour; and A. sanguined, 

 found in May-blossom, is of a bright red tint. 



The Gallerucae are mostly narrow in shape, dull-yellow 

 or brown in colour, roughly granulated, covered with a 

 close powdery grey pubescence, and gregarious; being 

 found in numbers on willows and water-plants. Their 

 larvae, which are sluggish, rather elongate, wrinkled, 

 and with lateral tubercles and an anal projection, serving 

 as an extra leg, live in company, and commit great 

 ravages, often stripping every leaf off the trees, etc., on 

 which they feed. 



Agelastica halensis, very common in the south, 

 abounding in grassy places towards the autumn, is our 

 brightest species ; it is upwards of a quarter of an inch 

 long, with its broad elytra and the top of its head bright 

 green, more or less running into dark blue, its mouth, 

 thorax, body and legs yellow, and tarsi, antennae, and 

 tips of tibiae black. 



Auchenia, adorned with four spots, and the narrow 

 delicate Calomicrus circumfusus (Plate XIV, Fig. 6) are
