1896.] BROI.EMANN. — Lithobius variegatus, Leach, 15 



near the posterior angles, posterior margin somewhat concave. 

 The above-mentioned sculpture or roughness having often 

 been noticed on immature specimens of L. forficatus, cannot 

 be considered as characteristic of L. variegatus. 



The posterior angles of the 7th dorsal plate, though not 

 much developed, project somewhat on the line of the posterior 

 margin, and the posterior angles of the 9th, nth, and r3th 

 dorsal plates are acutely produced. 



The two last pairs of legs are thin and long. The following 

 details are to be observed as well on female as on male 

 specimens, but are more marked on the 15th than on the 14th 

 pair of legs. The superior inside edge of the third joint is 

 hollowed longitudinally, the furrow being wider at the back 

 end ; also the superior outside edge is sulcate, the furrow 

 being only noticeable on the posterior two-thirds of the joint ; 

 the superior surface is thus reduced to a rounded ridge. These 

 two furrows are continued on the following joint, the fourth, 

 being narrow and deep : on the fifth joint, only the inside 

 furrow is to be found, being much attenuated. On the inferior 

 surface of the third joint a rounded ridge runs longitudinally 

 between two furrows, the outer of which is often shortened. 



The spines of the ist, 14th, and 15th pairs of legs are 

 disposed as follows : — 



, . 0.0.2.1 0.1 O. , VI 1 



ist pair, , double claw. 



0.0.0. 2. I. 



14th pair, '^' ' ' , double claw. 

 0.1.3.3.2. 



15th pair, , single claw. 



0.1.3.3. 1. 



The spine of the fifth joint, below, occupies the medial 

 position. 



Female genitalia armed with 2-1-2 strong spines, the outer 

 pair of which .is the larger ; claw strong but narrow, with a 

 blunt tooth on the inside edge. 



Coxal pores large, circular, disposed on one line, numbering 



6-5-5-5-, 5444- 



This species much resembles L. leptopus, I^atzel, from which 



it is easily distinguished by the arrangement and number of 



coxal pores.
