A NEW SPECIES OF HAEMAPHYSALIS FROM EAST AFRICA. 
By C. W. Howard, Entomologist for the Province of Mogambique. 
Haemaphysalis africana, n. sp. 
Male : Of very small size, 2 mm. long by 1.5 mm. wide, the widest 
point being at the middle of the length of the shield. Colour light yellowish 
brown, a little darker in the lateral and posterior portions of the dorsal 
shield, through which the ramifications of the intestines show as darker 
lines ; the ventral surface is bluish in colour. Dorsal shield convex, 
covers all of the dorsal surface of the body ; narrow in front, widely 
rounded behind ; surface finely roughened over its entire extent, 
numerous, large, unequal, shallow punctuations scattered over its surface, 
most numerous in the posterior portions; two large shallow depressions 
one on each side of the median line near the posterior margin ; cervical 
emargination not very deep ; coxae I projecting slightly beyond the sharp 
cervical angles of the shield ; cervical grooves wide, shallow, and short, 
converging toward the median line ; lateral grooves well marked, hut 
not deep, beginning at the anterior edge of coxae III and extending to 
the division between the ultimate and penultimate festoons ; posterior 
festoons sharply marked, eleven in number, longer than wide, hearing 
a few large, shallow punctuations and a few small hairs on the posterior 
margin ; no eyes ; dorsal porose areas below the middle of the length of 
the shield. Rostrum with base rectangular, twice as long as wide ; on 
dorsal surface, with posterior angles long and sharp ; ventral surface of 
base as long as wide ; palpi with article I very small and hidden, article 
IT with lateral edges protracted in the posterior half into a long, sharp 
spine somewhat longer than the length of the article itself, this lateral 
spine is slightly protracted posteriorly on the; dorsal surface ; article III 
as wide as long on the dorsal surface, conical in outline ; median edge of 
articles II and III protracted on dorsal surface over the mandibular 
sheath ; ventral surface of article III bears article IV in a large con- 
cavity ; article IY papilliform bearing on its tip a bunch of about fifteen 
short, stout spines and several tubercular spines near its base ; article II 
bears nine large pinnate spines on the medio-ventral edge, article III 
bears four similar spines on the posterior portion of its medio-ventral 
edge ; hypostome of usual type, numerous small denticles at tip followed 
on each half by a transverse row of three blunt teeth, these succeeded by 
eight transverse rows of four teeth each, with a final row of two teeth, 
the teeth extending farthest posteriorly on the lateral edges, all teeth 
except those at the tip are very sharp and of medium size ; mandibles 
with outer apophyses bearing three teeth, the posterior tooth largest and 
widely separated from the two anterior teeth, inner apophysis slender, 
bearing below its tip a large tridentate transverse process. Ventral sur- 
face with numerous large, shallow punctuations unevenly distributed ; 
genital pore opposite the anterior edge of coxae II, with an elongate semi- 
circular thickened portion forming the posterior margin ; genital grooves 
deep, almost parallel until just anterior of the anus, when they curve 
slightly outward and pass beyond the anus, Teaching nearly to the 
posterior margin opposite the festoon third from the middle ; anus at the 
posterior third of the length of the body, with six large spines on each 
valve near the circumference ; anal groove passes behind and close to 
the anus, not quite joining the genital grooves on each side in front ; 
ano-marginal groove almost reaching the posterior festoons-; no ventral
