328 MR. STANLEY HIEST ON AEACHNIDA AND 



$ . Scutum cordiform and wider than long. Punctures large and numerous ; 

 anteriorly they are fewer in number on the sides and shoulders. Cervical grooves 

 deep, but rather ill defined posteriorly, owing to the proximity of some of the coarse 

 punctures ; in one specimen they are continued posteriorly by short divergent grooves. 

 Eyes obsolete. Stigmal plate large and very wide. Capittiluru long ; its base has 

 small but distinct cornua, and the porose areas are circular and widely separated 

 from one another ; hypostonie with four longitudinal files of denticles on each side, 

 those of the innermost file being very small. Armature of basal segments of the legs 

 practically the same as in the male sex. (Nearly all the legs are missing, hence 

 further details of their structure cannot be given.) Colour of scutum dark brown, 

 a narrow transverse strip of whitish enamel-like coloration is present on the 

 shoulders. 



Measurements. Length of body 7 mm. ; of scutum (along median line) 1-7 ; 

 greatest width of scutum 2'2. 



Localities. Mimika Tliver ; a male example (the type) and two nymphs. Canoe 

 Camp, Utakwa River (Nov. 1912) ; two females. Name of host not given. 



Test-figuro 15. 



Amhhjomma 2>a2ni(ma, sp. n., (J . Basal segments of legs from below. 



Bemarlcs. Owing to its small size and the shape of its body, the male of this 

 new species of Amhhjomma presents a strong resemblance to the species of Ajjonomma, 

 but eyes are present, although obsolete and very inconspicuous, and therefore it 

 cannot be referred to that subgenus. Personally, however, I consider that the 

 subgenus Aponomma should be abandoned and its species regarded merely as aberrant 

 forms of Amhlyomma. 



Genus HxEMAPHTSALIS C. L. Koch.

6 . Body long oval, and narrowed anteriorly. Sciitmn furnished with numerous
