MYRIOl'ODA FROM liURMA 801 



of the body tlie keels do not project straight backwards as den- 

 tiform processes but are more bluntly rounded. The c/ differs 

 correspondingly from what has been identified as the cT of 

 pingnis; and does not appear to differ from it in sexual features 



Length of 9 42 mm.; width mm. 



Length of a^ 43; width 6. 



Loc. Meteleo, in the Carin Mountains 900-1200 m. (Fea coll.). 



It may be added that the colour of obosus is browner than 

 that of pinguis and the legs are a richer yellow ; but none of 

 the specimens of these two species appear to me to show the 

 colouring of the mature animal, which will probably be found 

 to be black or deep brown, with yellow keels, tail, antennae 

 and legs. 



The following key may help in the determination of the 

 preceding species : 



9 a. Keels larger, as long as the area of the tergum that sup- 

 ports them, their posterior borders not directed obliquely 

 forwards. 



a^ Legs and antennae fuscous; keels with thicker mar- 

 gins and postei'ior angles less produced: keel on 19"' 



almost obsolete anthracinm 



6' Legs and antennae fulvous, keels with margins 

 thinner and more produced posterior angle ; that on 



the 19*1» dentiform str Mains. 



h. Keels smaller, narrowed distally, the posterior borders 



(except quite at the hinder end) directed obliquely forwards. 



a* Keels smaller, those at the posterior end of the body 



(segm. 17-19) sharp and dentiform phu/uis. 



b- Keels larger, those at the posterior end of the bodj^ 



with blunt apices obesas 



Genus Strongylosoma, Brandt. 

 11. Strong-ylosonaa ocellatum, sp. u. 



(Fig. 8). 



Colour piceous, paler beneath ; a large median testaceous spot 

 in tlie middle of the upper surface of the keel-bearing half
