MYRIOPODA FROM BURMA 827 



a' The stripes on the dorsal surface much 

 more parallel sided, not so conspicuously 

 constricted on a level with the anterior 



suture hivittata. 



b' The dorsal stripes irregular owing to the 



constriction of the spots where they pass 



over the above mentioned gi'ooves. 



a* Sides of the body black immediately 



beneath the keel, clear yellow in its 



lower two-thirds miranda. 



6" Sides of the body fuscous almost down 



to the legs melanopleurls and bistrlala 



b* Upper surfiice of the segments not ornamented with a 

 pair of conspicuous longitudinal bands (only very faint 

 ones in minlana)\ the segments either fuscous with yellow 

 keels or fuscous in front and yellow behind, presenting 

 a transversely banded aspect. 



a^ Side margins of the keels very little thickened, di- 

 stinctly bisinuate, a minute denticle marking the an- 

 terior sinuation, the anterior border convex ly pro- 

 duced and rounded , the posterior angle acutely 

 produced and spiniform. 

 a"* Pores visible from above; a faint median pale 



dorsal spot on the terga silvestris 



6'° Pores invisible from above; without a pale median 



dorsal spot doriae. 



b" Side borders of the keels much more noticeably 

 thickened, less noticeably bisinuate and without a 

 distinct denticle. 



a" Middle of the dorsal surface occupied by a wide 

 uninterrupted longitudinal black band; the keel 

 and adjacent area of the tergal portion flavous, 

 with faint traces of the pale bands that are 

 l»resented in miranda and its allies; legs pale, 



antennae black minlana. 



è" Middle of the dorsal surface not occupied by a 

 continuous and wide black band, at least the po- 

 sterior part of the keel- bearing portion trans- 

 versely flavous. 



a'* The first tergite entirely flavous, the rest of 

 the keel-bearing portions almost entirely fla- 

 vous above, at most a very thin stripe spread-
