0Ï Heterodoxus-Wkç. appearance; head completely rounded 

 at the sides, with the chitinous cleft on the sides of the 

 forehead in front of the eyes much deeper, with two dagger- 

 like chitinous spines beneath the head rising from the base 

 of palpi but much smaller than in Heterodoxus; mesothorax 

 very much reduced in size, appearing from above as a little 

 chitinous plate connecting pro- and metathorax, with four 

 strong chitinous spines between the coxœ, metathorax trian- 

 gular in shape, sides strongly tapering to the front margin, 

 posterior angles producted to an obtuse process, carrying a 

 very long chitinous hair; abdomen with a regular transversal 

 row of 30 — 40 fine, flattened chitinous set» and six longi- 

 tudinal rows of much longer hairs; last segment in $ ending 

 in two forceps-like sharply pointed movable processes (the

Phacogalia n. g. 



Typus: Heterodoxus brevispinoszis Harris. & Johnst. 



Harrison and Johnston have described this form 

 (»Mallophaga from marsupials L). — Parasitology Vol. VIII 

 N:o 3, 1916) on a single female found on Phascologale fla- 

 vipes. My material is very large, comprizing a large 

 number of specimens of both sexes, enabling me to analyse
