having subapical yellowish fascire, constricted in the middle anteriorly, 

 that on the fourth segment slightly interrupted in the middle, and by

 metathorax, but obsolete at base; otherwise as in picta. Length T-i

One 9 specimen. A beautiful species, with the markings very bright 

 and distinct.
