Chilopods of the (re^iMS Mecistoceplialiis. 331 



(PI. X. fig. 9). Anterior areolated baud o£ clypeal region 

 longer than the i)Hirc(] posterior areas. Su!)lateral teeth 

 large, aeute (PI. XI. Hg. 1). 



Median piece of la!)nim not or scarcely overlapped 

 laterally by the lateral pieces, moderately narrowed caiidaci, 

 the caudal end triangular. Lateral pieces with caudomesal 

 corners characteristically broadly rounded. Anterior edges 

 of lateral pieces when produced forming a pronounced 

 "obtuse angle. Margins wholly smooth (PL XI. fig. 2). 



Posterior corners of coxosternum of second maxilla acutely 

 produced; entire region caudad of pores and abroad median 

 band areolate. Pores narrowly elliptic. Ectal angles of 

 coxae of first maxillae elevated and broadly rounded (PI. XI. 

 fig. 3). 



iM audible with six iamellee, of which the first has six 

 teeth. jNIesal corner beloAV first lamella acutely produced, 

 the margin entire (PI. XI. fig. 4). Teeth of median lamellae 

 all long, not reduced at proximal end, typically near fifteen 

 in number. 



Antennae moderately attenuated. Last article clearly 

 longer than the penult, but shorter than the penult and 

 antejjenult together. Sixth article longer than wide at 

 distal end, in about ratio 5 : 4. 



Exposed area of prosteruum wider than long, in ratio 9 : 7. 

 Anterior margin with the two teeth normally developed. 

 Femuroid with two teeth, these rather broad, low and 

 rounded, the distal one the larger. Next two joints also 

 bearing teeth, of which the second is decidedly the larger. 

 Claw with angulation at base, but without distinct tooth 

 above this (PI. X. fig. 10). 



First leg about three-fifths as long as the second. 



Sternal impressions of anterior segments furcate, but the 

 branches very short; angle obtuse; branches disappearing 

 caudad as usual (PI. X. tig. 11). 



Sternite of pregenital segment broad anteriorly, strongly 

 narrowed caudad, almost triangular, the caudal end lather 

 narrowly rounded. Coxopleura3 with a moderate number 

 of small pores, the total number on each side being twenty 

 of which about twelve are visible in strictly ventral view 

 Anal pores distinct. Last legs about twice as long as tlie 

 penult.
