affecting the Clover-crops and Pasture-lands. 49 



I must not omit to state that it has been recorded that Altica 

 nemorum (the turnip beetle or fly) not only inhabits clover-fields, 

 but feeds upon the leaves. 



We will now take a view of the moths which resort to clover- 

 fields in order to deposit their eggs, so that the caterpillars may 

 be nourished on the leaves when the eggs hatch. 



These insects belong to the order LepidopteeA, and there is 

 also a beautiful butterfly, which is not abundant every year, but 

 is occasionally not very rare about clover-fields, over which it 

 flies, and deposits its eargs on a trefoil named Antliyllis vulnera- 

 ria (the Kidney-vetch). As this plant does not form an important 

 crop with the English agriculturist, I shall merely observe that 

 the insect alluded to is named 



5. PapiliO ( Colias) Hyale, Linn. : the pale-clouded Yellow 



Butterfly. 



As figures and descriptions of this handsome butterfly are 

 given in the 'British Entomology'* and other works, it is un- 

 necessary to describe it here. It flies in August and September. 



There is a large hairy caterpillar which lives on the clover, and 

 produces a fine moth belonging to the FAMILY BOMBYCID/E, and 

 to the GENUS LasioCAMPA ; it is named 



6. BoMBYX {Lasiocampa) Tpjfolii, Liiin. : the Grass or 

 Clover Eggar Moth. 



Head short ; eyes small ; horns inserted towards the hind part 

 of the heat], forming nearly a straight bristle : in the males they 

 are like two beautiful feathers, with a double row of rays ; in the 

 females the bristles are merely serrated. It has no tongue or pro- 

 boscis, as moths generally have, but in front of the head are two 

 small, short, hairy lobes, being the palpi, or feelers, which, when 

 denuded of the hair, appear to be triarticulate. The males are 

 always smaller than the females ; the trunk is large, not crested. 

 The body of the male is attenuated and cleft at the apex ; in the 

 female it is stout and somewhat oval, being generally filled with 

 eggs. The wings are rounded and entire, and when closed are 

 deflected, forming a ridge down the back. 



This moth varies greatly in colour, from a rusty grey to a brown 

 tint, and the females are always paler ; the superior wings are 

 darkest at the base, with a waved flesh-coloured line towards the 

 hinder margin, and near the centre is a white or cream-coloured 

 spot : the under wings are of a uniform colour ; legs hairy, stout ; 

 the feet composed of five joints, terminated by distinct claws and
