the right and left seta? of each pair would form an elongated 

 inverted "Y". 



Citri Risso — (Fig. 4). The cephalic pair of setae are separ- 

 ated by a space equal to half their distance apart from the 

 caudal pair of anal setae. They are from twice to nearly sub- 

 equal the size of the setae of the posterior pair. The caudal 

 pair of seta? are seiiarate from the cephalic pair liy a distance 

 equalling three-fourths of the distance of the cephalic pair from 

 the caudal pair of anal ring setae. The setae of the caudal pair 

 are considerably farther apart than the setae of the anterior 

 pair. Lines drawn longitudinally through the corresponding 

 right and left setae of each pair would form a normal inverted 

 "V". 



Cratvii Coq. — (Fig. 3). The cephalic pair of setae are separ- 

 ated from the caudal pair of anal setfe by a space equalling 

 two-thirds their distance apart. The caudal pair of setae are 

 separated from the cephalic pair of seta? by a space equalling 

 three-fourths the distance of the cephalic pair from the caudal 

 pair of anal ring setfp. The setfe of the caudal pair are slightly 

 nearer together than the setae of the anterior pair. Lines 

 drawn longitudinally through the corresponding right and left 

 setae of each ijair would be parallel. The setae of each pair 

 are robust. 



Ohscurus Essig — (Fig. '!). The cephalic pair of setae are 

 distant from the caudal pair of anal setae by a space equalling 

 two-thirds their distance apart. The set* of the cephalic pair 

 are separated from each other by a space equal to the distance 

 apart of the caudal setae of the anal ring less the width of the 

 base of one anal ring setae. The caudal pair of setae are separ- 

 ated from the cephalic pair of setae by a space equalling one- 

 half the distance of the cephalic pair from the caudal pair of 

 the anal ring setae. They are smaller than the setae of the 

 cephalic pair. Lines drawn longitudinally through the corre- 

 sponding right and left setae of each pair form a normal "Y". 



Agrifoliae Essig — (Fig. 1). The setae of the cephalic pair 

 are separated from each other by a space equal to the distance
