4 SJOSTEDTS KILIMAXDJARO-MERU EXPEDITION 11:1. 



Modified segments. -- <j\ The eighth sternite is large, triangular, the apex being 

 rounded off. It bears a number of small hairs, which are more numerous near the 

 ventral edge. The dorsal manubrium (M 1 ) of the ninth tergite (PL 1. fig. 3) has the 

 tip curved down-wards, while the lower manubrium (M 2 ) is practically straight. The 

 upper process (F 1 ) of the clasper is long, slender in side-view, and hairy, while the 

 lower process (F 3 ) is very short. In dorsal aspect the process F l is lanceolate (PL 1. 

 fig. 4). The ninth sternite (ix. st) is elongate-triangular with the tip curved upwards 

 to form a hook. - - ?. The eighth tergite (PL 1. fig. 5) does not bear any bristles on 

 the dorsal half, while there is a row of short stout bristles along the apical edge and 

 one or two bristles on the side on the lower half of the sclerite. The rim of the 

 sensory organ projects dorsally over the organ itself. The apex of the anal tergite 

 bears some stout spines; the anal sternite is small (PL 1. fig. 5). The stylet is coni- 

 cal, being about three times as long as it is broad at the base. 



Length (of specimens in alcohol): d" IVa mm., ? 2 1 /s mm. 



A series of both sexes from the Massai-steppe, off Pkacochoeriis africamts, and 

 also from the Kibonoto-steppe of the same host, October 9. 



Ceratophyllus hifestus spec. nov. 



PL 1. fig. 6. 7. - - A near ally of C. fasciatus Bosc. (1801), but larger, diffe- 

 ring especially in the hairs of the abdomen and in the structure of the modified 

 segments. 



Abdomen. - - The short spines placed at the apical edges of the proximal seg- 

 ments are situated in a deep sinus. The sternites are much more hairy than in C. 

 fasciatus. The first sternite bears in the J 1 about 5 hairs on the side, while there are 

 15 or more in the ?. The next four sternites have a row of 3 or 4 (c?) or 4 to 5 

 (?) bristles and in front of this row a number of shorter ones, which are more nu- 

 merous in the ? than in the d", there being in the ? as many as 16 bristles al- 

 together on each side of the sternite of the third segment. Legs. -- The tarsi are 

 stouter than in C. fasciatiift, the fifth segment especially being broader. Modified 

 segments. J 1 . The eighth tergite (PL 1. fig. 6, VIII t) is large and bears at the edge 

 numerous long and short bristles, there being also some on the side. The lower distal 

 angle of this sclerite is produced into a short finger-like process. The manubrium (M) 

 of the clasper is much broader than in C. fasciatus. The dorsal portion of the ninth 

 tergite (ix. t) projects frontad. The ventral edge of the clasper (Cl) is strongly 

 convex. The finger (F) somewhat resembles that of C. fasciatus, bearing at the distal 

 edge three bristles and a short hair. The ninth sternite (ix. st) is also of the same 

 type as in C. fasciatus, the horizontal arm being divided by a ventral sinus into a 

 proximal and a distal portion. - - ?. The seventh sternite (PL 1. fig. 7, viii. st) is sinuate, 

 the sinus being very narrow. The bristles on the eighth tergite are more numerous 

 than in C. fasciatus.
