These ticks possess a type of scutum, broad posteriorly, which

observable in I. australiensis, I. ornithorhynchi and I. tasmani, and the 
scutum of the nymph of I. vestitus is of this shape, though, in the adult 
female, it tends to become more circular.. I. tenuirostris alone of extra- 
Australian species conforms to this type. The species here described 
most clearly resembles I. vestitus in general characteristics.

Male livid yellow-brown, very long and narrow, T9 x - 9 mm. Scutum 
glossy, with very uneven surface due to more or less confluent 
punctations and ridges; cervical grooves long and nearly straight, 
slightly diverging posteriorly; lateral grooves long and very near the 
border, enclosing one festoon ; festoons moderately long, the intervals 
curved. Capitulum '3 mm. long, base rather long, with long sharp 
cornua proceeding rather from the dorsal surface. Hypostome with very

times as long as article 3 ; its sharp external angle being much posterior 
to its insertion ; no dorsal spur; a very small sharp spur under article 3. 
Venter : genital aperture between coxae II, covered by an elongate 
shield. Spiracles large, broader posteriorly, but without definite dorsal 
process. Legs : coxae very elongate and progressively increasing in size, 
all more or less pointed at the internal angle, the spur on coxa IV dark
