Head is yellowish brown ; scutellum has the anterior half 

 blackish, except at margin which is yellowish, as is the posterior 

 area ; segmental area of prothorax is yellow ; mesothorax thinly 

 bright red doi'sally and subdorsally, yellow below ; postthorax 

 and 1 to 9 abdominal segments are divided transversely, anterior 

 red, posterior yellow, sections, above the spiracles the band is 

 dull red, at and below the spiracles and ventrally it is bright 

 red ; the posterior dorsal humps are brighter red than are the 

 anterior humps ; the anal segment is wholly yellowish brown. 



Shape : Viewed dorsally, is uniform, robust ; viewed late- 

 rally, the meso and post-thoracic segments are " weaker " than 

 others. Head: Finely striate. Prothorax: Scutellum finely 

 striate anteiior, and finely spiculate on posterior area, four larger 

 spicules are arranged in a trapezoidal position, i.e., two in front 

 approximate (with some minute spicules between them) and two 

 posterior remote. On either 'lide of the median line of scutellum 

 are one anterior, two posterior dorsal setae on the unspiculate 

 area of scutellum ; two anterior and one central setae are on a 

 lateral subdivision of the scutellum ; a prespiracular tubercle 

 bears two long setae with a small inner seta near the spiracle. 

 Spiracle is very large, above the legs a tubercle bears two setae. 

 Meso and post thorax : the dorsal and subdorsal setae are dupli- 

 cate pairs ; lower a more central lateral tubercle bears a single 

 seta, and an anterior tubercle bears also a single seta, between 

 these tubercles a rudimentary spiracle or scar may be detected ; 

 a lower anterior tubercle bears a single seta, and tubercle above 

 legs bears one seta. 



Abdominal segments : the dorsal humps are divided trans- 

 versely, not longitudinally, and are covered with minute spicules, 

 the anterior hump is largest. The trapezoidal tubercles are 

 normal with a single seta each, placed on the segmental area, 

 not on the humps. The siipraspiracular tubercle has a single 

 long seta above the large oval spiracle, and there is a remote 

 anterior supra spiracular tubercle with a minute seta. The sub- 

 spiracular tubercles each have a single seta, the anterior highest 

 in position ; above the legs a tubercle bears one central seta ; 

 the basal setae are three in number, one being abjve the others, 

 not in line with them. Segment 9 has the anterior trapezoidals 

 remote, posterior trapezoidals inner ; 10 has two small blunt 

 protuberances of red colour representing what in other species 

 are a pair of anal horns, the setae are one anterior, one level 

 with horn, one posterior, one more lateral, three lateral setae
