gitudinal striae are only developed quite on the lower surface of the 

 lateral portion. The pores are considerably above the middle of the 

 side. The anal somite is shorter, the superior angle being less deve- 

 loped and more obtuse and rounded, more coarsely sculptured, with 

 a transverse constriction at its base; the valves more convex, the 

 marginal constriction being shallower; the anal sternite much wider 

 in proportion to its length, being in fact about twice as wide as 

 long , whereas in R. semicinctus the length is nearly equal to the width. 

 Number of segments 47. 



Length 51 mm. ; width 5,5. 



91. Rhinocricus eumelanus sp. n. PI. XXII, fig. 26. 

 Celebes: Bira. 



Closely allied to the preceding. 



Colour black or very deep greenish black throughout, legs with a 

 very faint ferruginous tinge. 



First tergite with its lateral angle widely rounded and marked with 

 a weak marginal sulcus. The rest of the somites entirely smooth, 

 shining, striate only just above the base of the legs and on the sterna ; 

 the transverse sulcus absent as in brachyproctus. Pores above the middle 

 of the side, the area margined. Anal somite small, tergite with its 

 angle not constricted at the base; valves convex with margins com- 

 pressed; sternite wide, strongly angular. 



Scobina small, crescentic at the anterior end of the body, smaller 

 and puncture like posteriorly, found on the somites between the 10 th 

 and about the 35 th . Copulatory feet with the median process of the 

 anterior piece, and the processes of the lateral pieces much more elon- 

 gate than in the preceding species. 



Number of somites 51. Length about 55 mm. 



I add the description of the following new species from Celebes. 

 Rhinocricus hickoni sp. n. 



Colour deep greenish black, the segments adorned with a marginal 

 yellow band which extends from the legs up to the pore; antennae 

 and legs rather paler in colour than the body. 



Head smooth, frontal sulcus deep below, the external labral punc- 

 ture obsolete.
