22 CAMPONISCUS LU1HDIVENTRIS. 



of the recurrent nervnres. Thomson treats Oamponiscus 

 as a subgenus of Hemichroa. As it is so easily known 

 from all the Nemati by the neuration, and as the 

 form of the larva is quite peculiar, I have preferred to 

 keep it distinct. It is, so far as is known, confined to 

 Europe (especially the north), and at present is repre- 

 sented by six species.
