A NEW LOUSE (H^EMATOPINUS OVILLUS, 

 NEUM.) FROM THE SHEEP. 



By WILLIAM EVANS, F.R.S.E. 



IN the spring of last year (1906), when collecting material 

 for a list of the parasitic Hemiptera of this district, I 

 obtained, through the kindness of Mr. W. F. Little, a 

 number of small brownish Anoplura taken from the face of 

 a sheep of the " Black-faced " breed at Crosswood, Pentland 

 Hills, Midlothian. The date on which they were taken was 

 the 3<Dth of April, and I was informed that this louse is 

 common in spring on the faces especi- 

 ally about the cheeks of sheep in that 

 part of the Pentlands. 



That these lice belonged to the 

 well-known genus Hcematopinus was 

 evident at a glance, but I could not 

 make them fit with any of the de- 

 scribed species, though it was clear 

 they were closely related to H. sten- 

 opsis, Burm., the louse of the goat. 

 Not being able to identify them, I sent 

 several examples to Professor L.-G. 

 Neumann of the Veterinary College, 

 Toulouse, for his opinion. He replied 

 that they undoubtedly belonged to a 

 new species, and that by an interesting 

 coincidence he had only a few weeks 

 before received from New Zealand a 

 specimen of the same parasite found there on the face of a 

 sheep belonging to the " Border- Leicester " breed, and had 

 written for further specimens to study before describing the
