slightly longer (fig. 26) ; yet it may be shorter and even 

 slightly bifid (fig. 25). S t y 1 i long, sharp. 



M a n d i 1) 1 e s long, reaching when wholly retracted the 

 posterior shield. ( * h e 1 a e (fig. 27) rather slender for a male ! 

 Tibial sense organ lanceolate, a considerable distance before 

 the joint of the lower jaw. Tarsal sense-organ also far for- 

 ward. Upper jaw with a kind of turned-np-nose a little before 

 the tarsal sense-organ, the usual end-incisor, and a small 

 knobby canine-tooth. Lower jaw with the usual end-incisor, 

 and with a saw of 7 small sharp backwardly directed canine- 

 teeth ; no molars, but the convex sharp upper-edge may serve 

 as scissors with the concave sharp lower edge of the upper 

 jaw. The lower jaw moreover shows a long split, apparently 

 originated by the fusion of the lower jaw itself (above the 

 split) with a copulation organ (below the split). Pu 1 vili u m 

 siugular : proximally an oval bladder in which is planted a 

 long transparent rod, which ends in a pencil of about 5 hairs. 



Maxillae (fig. 28). Underside of capitulum with the 

 usual 4 })airs of long bristles. Bristles I, II and III stand on 

 a brown strongly chitinized more or less rodlike base of the 

 horn. Hair I close to the horn. Hairs II and III far backward, 

 close together. Between these horn-bases or horn-peduncles 

 and the inner malae a deej) cleft. Inner malae fused together 

 to form a triangular transparent underlip, distally rounded 

 and laterally fringed, so that this lip shows two tufts (fig, 

 29, 30, 31). Horns bifid, one of the teeth blunt. Palps 

 slender ; dorsally (fig. 22) the femur with the usual middle 

 hair, which here is stiti* and directed obliquely forward and 

 inward and distally downw^ard ; and with the distal transparent 

 pin, which here is not quite on the inner angle but more 

 dorsal. V e n t r a 1 1 y the trochanter (fig. 31) with two knobs, 

 one inner one and the other more ventral one, on which is 

 planted the distal bristle ; moreover the usual distal and inner 

 sharp transparent pin. The femur with the usual outer and
