■chitinous papilla, which is probably the peoiis. The larger distal 

 end of this papilla is supported on each side by a chitinous 

 margin — these latter parts, lower down, running into one another 

 and foi'ming a narrow neck. 



The egg is shown in outline in text-fig. 7. The egg is large 

 and fastened to the hair by a very strong thick cement along a 

 straight inner surface, equal almost to two-thirds its total length. 

 The shell and the lid are quite smooth. The micropyle appara,tus 

 on the lid consists of a number of very minute canals, which do 

 not, as in many Anoplura, project as papillfe on the lid. Length 

 1"5 mm. ; greatest width '72 mm. 



Larva, Stage I. (text-fig. 8). — Head is veiy rounded. Abdomen 

 without sclerites, ovate, smooth mai'gin all the way round. 

 Thorax with straight hind margin. Almost bald, except for 

 two mesonotal hairs and two long hairs on each side of the last 

 segment of abdomen. Other minute hairs as shown in the text- 

 figure. Described from a single specimen. 



Measurements {^millitnetre scale). 



Length of antenna '33 mm. 



MALLOPHAGA. 

 Genus Boopia Piaget. 

 BoopiA TARSATA Piaget (2, p. 599). (Text-fig. 9.) 



Twenty-two specimens from Phascolomys mitchelli Owen. 

 Piaget's specimens were taken on a P.fossor. 



In all the males the copulatory apparatus was unfortunately 

 retracted. It is practically impossible to di'aw out these jjarts in 

 a dead specimen, and in our present state of knowledge very 

 unsafe to describe such a complex structure as they present so 

 long as they are withdrawn within the abdomen. 



Mouth-parts. — A brief reference to the oesophageal sclerite in 

 Boopia is made in my paper in the P. Z. S. for 1913, p. 138. The 

 following description confirms the statement there made and 

 ■extends it, all parts of the mouth being passed in review.
