one spine; of the anal ^■-''-f-- 1-/", the claw unarmed; last two coxse armed 

 laterally with a stout spine. 



Coxal pores 6, 7, 7, 6-6, 7, 8, 8, transversely elongate. 



Gonopods of female with the claw tripartite, the lateral lobes much 

 reduced, almost minute; basal spines 2-2, stout, clavately thickened 

 distally. 



Genital appendages of male short and wart-like, pilose. 



Length of body 20 mm.; width of 10th plate 2.6 mm.; length of 

 antennae 8.1 mm.; of anal legs 8.2 mm. 



Remarks. — The description is based upon two adult specimens, a 

 male and a female. This species seems to be nearest L. howei Boll., 

 from which, however, it may easily be separated l^y the characters 

 assigned in the diagnosis. 

 Lithobius Beulae sp. nov. 



Diagnosis. — Angles of none of the dorsal plates produced; head but 

 little wider than long (10.5: 10); articles of antennte 21; ocelli 9-11, in 

 two series; prosternal teeth 2-2; spines of first legs beneath 0. 2, 1, of 

 penult 1, 3, 3, 1, the claw armed with a single spine; posterior coxse 

 unarmed beneath or laterally; coxal pores 2, 3, 3, 3, round; length 

 8 mm. 



Description. — Body, head and antenna? brown, legs paler; polished; 

 dorsum uniformly sparsely pilose with short hairs, hairs of venter 

 more scattered; head subglabrous; legs, ]3rosternum and prehensorial 

 feet sparsely pilose; antennse proximally Avith but few hairs or sub- 

 glabrous, distally rather densely pilose; genital and anal segments 

 clothed l^elow with long hairs. 



Head cordiform, posterior border truncate; a little wider than long 

 (10.5: 10); posterior lateral borders depressed; impressed on posterior 

 portion with two longitudinal diverging sulci, each with a tendency to 

 split into two lines anteriorly. 



Ocelli in a linear patch, 9-11 in number, arranged in two series 

 (1+3,5-1+4,6). 



Antenna^ short, articles 21, mostly short, the ultimate long and cylin- 

 drical. 



Prosternal teeth 2-2, pale, acute. 



Principal dorsal plates all margined laterally and caudally ; the lateral 

 and posterior borders, especially in the anterior plates, depressed, the 

 dorsum within border strongly arched, bisulcate; posterior borders of 

 lesser plates all straight, of principal ones gently sinuate, none pro- 

 duced,
