Length up to about 28 mm. 



Locality Bhamo (Sig, L. Fea). Also a single specimen that 

 appears to belong to this species from Malewoon. This species 

 differs from Sp. feae, gestri, spiculifer etc. in having tlie transverse 

 groove on the tergites very deep , and the area behind appa- 

 rently raised. 



17. Spirolbolus nxaculiirer', sp. n. 



Colour (in alcohol) blackish or brownish with a double band 

 of yellow spots extending along the dorsal side from about the 

 7.*^' segment to the end of the body; legs, antennae, valves 

 and tip of caudal process ochraceous. Head smooth, with 3 or 

 4 setiferous pores on each side of the labrum. Antennae much 

 shorter than the head. Eyes, consisting of 6 transverse rows of 

 ocelli, separated by a space that is about equal to twice a dia- 

 meter. Collum smooth or nearly so, extending laterali} nearly 

 as low as the inferior edge of the 2."*^, the posterior border 

 lightly emarginate above the posterior angle ; a groove defining 

 the inferior margin and the anterior margin as high as the 

 eye, the anterior angle obtuse. The rest of the somites with the 

 posterior part smooth above and distinctly elevated ; the trans- 

 verse sulcus deep and ornamented with circular or crescentic 

 impressions, similar impressions adorning the posterior part of 

 the dorsal area ; lateral surface striate nearly up to the pore, 

 the striae crossing the transverse sulcus and extending obliquely 

 upwards and backwards. Pore behind the sulcus. The scobina 

 present, appearing as two long transverse grooves quite on the 

 anterior margin of the somites, with a transversely striate patch 

 behind each ; the posterior border of the tergites di'stinctly bi- 

 sinuate as in undidatus of Karsch. Anal tergite furnished with 

 a short caudal process which projects bej'^ond the valves; valves 

 with simple margins, neither thickened nor compressed; sternite 

 evenly rounded. Legs moderately long and slender, with a single 

 seta on the lower surface of each. Z'. The second segment of 

 the legs inferiorly longitudinally sulcate, the coxae of the first
