522 MR. F. O. SINCLAIR ON THE [Dec. 3, 



of the keels, including the second, are divided into five clearly 



marked lobes, and after the 4th have a high raised tubercle, 

 resembling a median keel. This keel is divided into three lobes 

 when viewed from the side, and when looked at from Ihe front 

 is bifid. These lobes differentiate the species very clearly from 

 armatus. The last tergite, too, does not project over the tail as 

 it does in the latter species. The openings of the trachea) are on 

 small tuberculiform elevations just behind the bases of the legs. 

 I have not been able to distinguish the pores, but have no doubt, 

 that they are as iu armatus. The amount of material was too 

 small to make so full an examination as I should have liked. 



Sub-Order J u l o i d b A Pocock. 

 Cambala calva Pocock, var. nov. (Plate XXXII. fig. 84.) 



From Gua Gambar near Biserat, Jala District. 



These specimens differ from the CambaJa calva of Pocock in the 

 absence of " the one complete and two very short crests above " 

 the margin of the first tergite. The material being abundant, I 

 was able to take off the first tergite and examine under a high 

 power, but could not see any crest. The size of the largest 

 specimen was about 35 mm. by 31. The specimens were too 

 much curled to allow of the longitudinal measurements being 

 very exact. 



Number of somites 58. The 2nd and 3rd tergites fully crested, 

 as described by Pocock. Pive crests on dorsal surface between 

 the two that bear the pores; 10 below them. In all about 

 23, but the most ventral are hard to make out as they are very 

 feebly marked. The antennae are situated on a slight elevation 

 shown iu the figure. 



Trachy.tulus ceylanicus Humbert, var. nov. 



Prom about 5000 ft., Guuong Inas, Perak State. 



The colour differs somewhat from Humbert's description, as 

 there is no dark line visible ; also the pore-bearing tubercles are 

 not black but dark brown. The tubercles forming the ridges 

 are not so sharp as in his figure, and the ridges on the first 

 tergite are not quite so strongly marked.
