MYRIOPODA FROM BURMA 815 



lateral surface entirely brownish black; anterior third of the 

 keels brownish black. 



Keels rising about the middle of the side, very small, without 

 anterior border, lateral border lightly convex, but little thickened, 

 posterior angle acute and produced, but so short that it only 

 noticeably surpasses the posterior border of the tergite in about 

 the last 8 or 9 keel-bearing segments. 



Legs with femora longer than tarsi and more than twice the 

 length of trochanter or tibia. 



Length 36; width 4.5 mm. 



Loc. Minhla (Comotto). A single 9 specimen. 



Differs from the preceding species in the Slrongylosoma-like 

 form of body ; smaller and less produced keels. 



25. Orth.om.oi'plia i>ard[alis5 sp. n. 



Colour of upper surface black , the first tergite with yellow^ 

 keels and an elongate median yellow spot, the rest of the ter- 

 gites marked with four yellow spots one on each keel and one 

 on each side of the middle line in front of the transverse sulcus; 

 head black, antennae black with a flavous spot at the base; 

 lateral surface fuscous above, paler below, ventral surface flavous, 

 legs flavous , with browner markings ; caudal process flavous

 slightly incrassate, segments 2-6 subequal. 



P^ lergite lightly rugulose, with a distinct though small keel 

 on each side; the 2"^* with a distinct horizontal keel, projecting 

 below the level of the keel of the 1^* and of the 3^^; the 3'-'^ 

 and 4"" keels with rounded anterior borders and acute posterior 

 angles. The keels of the rest of the somites rising near the middle 

 of the lateral surfaoe, all of them small and without a distinct 

 anterior border, the posterior angle in the anterior half of the 

 body being only a little produced backwards, but more strongly
