very troublesome to the housewife, by getting into 

 the chimneys, and laying its eggs in the bacon while 

 it is drying: these eggs produce maggots called 

 jumpers, which, harbouring in the gammons and best 

 parts of the hogs, eat down to the bone, and make 

 great waste. This fly I suspect to be a variety of the 

 Miisca putris of Linnaeus : it is to be seen in the sum- 

 mer in farm-kitchens, on the bacon-racks and about 

 the mantelpieces, and on the ceilings. 



The insect that infests turnips and many crops in 

 the garden (destroying often whole fields while in 

 their seedling leaves) is an animal that wants to be 

 better known. The country people here call it the 

 turnip-fly and black dolphin ; but I know it to be one 

 of the coleoptera ; the ^' Chrysoniela oleracea saltato- 

 ria, femoribus posticis crassissimis" — "the vaulting 

 chrysoniela, with the back part of the thighs very 

 thick." In very hot summers they abound to an 

 amazing degree, and, as you walk in a field or in a 

 garden, make a pattering like rain, by jumping on 

 the leaves of the turnips or cabbages. 



There is an oestrus, known in these parts to every 

 ploughboy, which, because it is omitted by Linnseus,* 

 is also passed over by late writers, and that is the 

 ciirvicauda of old Moufet, mentioned by Derham in 

 his '' Physico-Theology," p. 250: an insect worthy of 



* This is a mistake on White's part : the Horse Bot-fly, Gasterophilus 

 equi. Leach, is described by Linngeus under the name of CEstrus bovis.
