Tiivropvgus weberi Pocock, var. now 



From Kuala Aring, Kelantan State. 



The principal differences are in size and colour. 



Somites 86. Length 115 mm. by 6 mm. 



Colour piceous above, shading into clear yellow on the edge of 

 the upper lip. Antennae dark yellowish brown, with yellow rings 

 at the joints. Somites piceous behind, the anterior part being 

 dark greyish yellow. Legs fuscous. Valves black. Labrum 

 indented, with six pores above the indentation. Eyes separated 

 by a diameter and a halt'. Antenna? extending to the hind 

 border of the second tergite. Frontal furrow extending to the 

 level of the points of the eyes. Collum wide laterally, posterior 

 angle slightly produced, inferior and anterior border with sulcus. 

 Two short but deep sulci on the posterior border. Anal ring 

 produced into a straight, short, blunt point. 



Spirostreptus sanguineus C. Koch. 



From Patani District; Bekit Besar, Jala District: Tapelung, 

 Patalung State ; and Bukit Jala, Jala District. 



Spirostreptus aterrimus Pocock. 



From Kuala Aring, Kelantan State. 



A larger specimen than Pocock's. Length 319 mm. by 15 mm. 

 68 somites. 



Spirostreptus rubripes, sp. nov. (Plate XXX. tigs. 2!), 30.) 



From Kuala Aring, Kelantan State. 



Colour black with red legs. 



Head. Frontal furrow to level of eyes. Distance between angle 

 of eyes less than a diameter. Antenna? short, the second joint 

 longest. Eyes about 55. Superior crenulate ridge at back of head. 



1st tergite comes to level of 2nd. Three stria? on posterior 

 lateral margin. Anterior margin with ridge and furrow from 

 level of eyes. Anterior angle obtuse, posterior slightly acute, 

 posterior edge slightly emarginate. Three pores on upper lip. 



In the other somites the stria? come close to the pore. The 

 pore is situated close to the raised (posterior) part of the segment, 

 which just in front of the pore juts out forwards and is lightly 

 elevated. The anal tergite is produced into a short blunt point 

 which does not project beyond the valves and curves downwards, 

 following the curve of the valves. 



This species seems to resemble Thyropygus inferomm of Silvestri, 

 hut far surpasses it in size and in the number of its somites.

 describe the smallest firsl .
