68 REPORT ON THE CENTIPEDES AND MILLIPEDES OBTAINED BY 



(a) Tubercles of anterior row smallei than those of the posterior ; pores about 



one diameter from the lateral border and two from the posterior border of 

 keels ; caudal process more quadrate, with posterior border lightly convex ; 

 terminal portion of copulatory apparatus curved inwards, ending in three 

 prongs Zodesmus. 



(b) Tubercles of anterior row as large as of posterior row ; pores in middle and 



at anterior end of body about two diameters from the lateral margin ; caudal 

 process longitudinally oval, terminal portion of copulatory organ bent upwards 

 and backwards, ending in five prongs Parazodesmus. 



(14) Parazodesmus verrucosus, sp. n. 



Colour black or deep chocolate brown, keels flavous, cylindrical part of the segments 

 pale above with a median dark spot ; caudal process entirely dark ; legs dark with 

 flavous coxa and trochanter ; sternal area dark, ventral portion of cylindrical half pale, 

 antennae dark brown. 



Antennae about equalling the width of the 1st tergite in length. 



First tergite with its antero-lateral border evenly convex. Second tergite with its 

 keels projecting below those of the 3rd, their lateral margins convex and five-tubercular. 

 Anterior border of keels of the middle segments of the body transverse, anterior angle 

 square, posterior angle acute, posterior border concave and directed slightly forward, 

 posterior border of only the last four keels projecting backwards. 



Hairs on legs clavate. 



Male smaller than female ; antennae longer than width of first tergite. The first 

 two processes of the copulatory organ given off close together on the outer side of 

 the terminal portion of the organ, the first (proximal) straight, directed backwards 

 parallel to the axis of the foot, the second semicircularly curved inwards, upwards and 

 backwards, the remaining three rising from a common base, the terminal pair long, 

 subequal and subsimilar curved, the fifth one arising as a short backwardly directed 

 process from the outer side of the base of the outer. 



$ length 36 mm., width 6 mm. 



Loc. Narowol, Solomon Islands. 



Specifically this species may be distinguished from Zodesmus tuberosus as follows : — 



(a) Moderately convex ; antennae, legs and sternal areas flavous, cylindrical half of 



segments a uniform chocolate brown tuberosus, Poc. 



(b) More strongly convex ; antennae and legs with the exception of the two basal 



segments, fuscous ; sterna also fuscous, cylindrical half of segments pale above, 

 with median brown spot verrucosus, sp. n.
