Colour: Head and 1st tergite reddish-brown, remainder dark olive- 

 brown ; legs yellowish on proximal half to green distally, distal portion of 

 anal legs light blue, the blue and green fading out in spirit. 



Head smooth, sparsely punctured, with 2 median longitudinal anteriorly 

 diverging sulci extending from the posterior border nearly to the middle 

 of the head. Post-cephalic plates moderately large and quite distinct. 

 Posterior border of the head angular, the tip engaged under the 1st tergite. 

 Antennae 17 joints, the proximal 5 smooth, the remainder pubescent. 

 Presternum of prehensors smooth, sparsely punctured, with irregular 

 transverse sulcus in anterior third. Dental plates very slightly narrowing 

 cephalad, teeth 4 -)- 4, the outer one slightly apart. 



Tergites : the 1st smooth and sparsely punctured, 2nd to 20th distinctly 

 bisulcate. Margining beginning faintly on the 5th (6th), distinctly on the 

 7th. From 4th or 5th the posterior border is slightly wrinkled and some- 

 what darker. Last tergite without median sulcus and produced roundly 

 backwards. Sternites bisulcate from 2nd to 20th, the 21st with a weak 

 median sulcus or depression, and stronply narrowed posteriorly. Spiracles 

 very narrowly triangular, slit-like. 



Coxopleurae (figs. 16 and 17) with narrow 2-spined conical process, 

 generally without small lateral spine,* pore-area extending partly along 

 process, the pores very fine and close-set. Anal legs : femur (tig. 17) outer 

 ventral with a single row of 3 spines, inner ventral with an oblique row of 

 3 spines leading to 2-spined angular spxxr, inner dorsal 2 spines. Terminal 

 claw with basal spur (fig. 18). 



Length, to 110 mm.

Colour uniform light brown, legs slightly lighter. 



Head smooth, sparsely punctured, 2 median longitudinal anteriorly 

 diverging sulci in posterior 3rd. Post-cephalic plates proportionally 

 smaller than in C. rubriceps. Antennae 17 joints, the proximal 6 smooth, 

 the remainder pubescent. Presternum smooth, sparsely punctured, no 

 irregular transverse sulcus in anterior 3rd. Dental plates and teeth as in 

 C. rubriceps. 



Tergites : 1st smooth and lightly punctured, 2nd to 20th distinctly 

 bisulcate ; margining beginning faintly on 7th and distinctly on 9th. No 

 wrinkles on posterior border of tergites. Last tergite without median 



* Kraepelin (1903) writes " zuweilen mit winzigem Seitendorn " ; but I have not 

 seen this small spine in the specimens I have examined.
