there is one conspicuous seta on the lower surface of each joint as 

 described in oaiesii. 



fc'MROSTE.EPTrrs TiTTATUs Pocock. (Plate XXX. figs. 27, 28.) 



The colour of this specimen differs from that described by 

 Poco -k, especially in the legs, but the resemblances are so great 

 that I think it must be regarded as a variety only, and not as a 

 new species. I shall, however, give a fairly full description, as 

 the points of difference may seem more considerable to others than 

 they do to me. 



Length 220 mm. by 12| mm. Somites 85. 



Colour. Head castaneo-piceous. 1st tergite castaneo-piceous ; 

 antenna) same. Other somites castaueo-piceous behind, paler, 

 almost oehraceous in front. Anal somite and valves the same 

 ochraceous colour, with the anal spike darker. Legs dark 

 castaneous, but lighter than the head. 



Head. Nearly smooth, slightly wrinkled below. Labial pores 

 six, somewhat irregularly placed. Frontal furrow terminating at 

 level of eyes. Eyes less than 60 but over 50, arranged in seven 

 transverse series. Space between ej^es a little less than a 

 diameter. Antennas reaching to end of 1st tergite ; second joint 

 the longest, the two end-joints slightly shorter than the third and 

 foui'th. Elevated striated ridge just below the edge of the 1st 

 tergite; where the frontal furrow joins this ridge, the ridge 

 p ojects a little to meet it and is cut a\Aay on each side of the 

 projection so that the margin of the ridge is sinuous in the middle 

 of the head. 



1st teryite. Large and sn'footh, narrowed laterally, both borders 

 be'ng distinctly emargiuate. The marginal sulcus extends to the 

 ey3 ; the anterior and posterior angles are rounded. It seems to 

 mo that the posterior angle is a little more rounded than in 

 PoLOck's figure. On the posterior edge there are three clear 

 striae and two more indistinct. Other somites with the transverse 

 furrow very distinct, the portion of the somite behind it being 

 ve.-y shghtiy higher than in front. Pore just behind the sulcns, 

 the latter being sinuate at this point. The longitudinal striae 

 extend nearly bnt not quite up to the poi"e. Concentric markings 

 on the front part of the somite. Ventral grooves small and short. 

 Anal somite moderate in size, the projection coming to the level 

 of the valves but not surpassing them. It is marked oil from the 

 rest of the tergite by a distinct constriction. 



Legs long ; one seta above and one below the claw ; a few hairs 

 on the lower surface of the joints. 



There are five immature specimens of Sprroholus from Gunong 

 Inas, Perak. It is not possible to determine the species without 

 a greater knowledge than I possess. 



JULUS BIBMAXUS PoCOck. 



Two specimens. I do not think either of them is full-grown.
