The Genus Ixodes 
Note : The 9 o and larva were described in Ticks, n. 198-200, 
Figs. 191-193 and the d in Parasitology iv. 175-179, Fig. 1. The accom¬ 
panying Fig. 21 illustrates the 9 specimen from Bosnia; a comparison 
of this and my earlier figure shows a slight degree of individual variation 
in the shape of the basis capituli, scutum and spiracle which it is well 
to take into account. The dentition of the hypostome is more accurately 
shown in the present figure. 
Ixodes canisuga Johnston 1849. Previously recorded from Scotland, England, 
Ireland, Germany, France. Add: Scotland: (N. 2380) os from red
