extending all round the ventral side of the segment, the basal and apical edges of 

 each segment produced ventrad as shown in figure, this projection widened laterad 

 near end, appearing spatulate in a ventral view. Tibiae with very fi'/c spines at 

 the end ; anterior tibia ending in a long naked t/wrn ; spurs of mid- and hindtibia 

 very short, oi/r pair to liiudtihia ; pulvillus and paronychium present. (!ell of 

 hindwing broad, lower angle not acute, about 1)0", R^ from centre of cell, stalk 

 of SC- and R' rather short. Distal margin of forewing dentate. Scales of 

 abdominal tergites long, no broad underscalcs, apical spines weak. 



S. Tenth tergite (PI. XXV. f. 1. 24) broad, flat, sinuate, the two lobes poiuted, 

 their tips curved downward ; tenth sternite very broad and short, transverse, the 

 edge incrassate, rounded. (Jlasper without friction-scales, apical half narrower than 

 liasal half, also less chitinised ; harpe nearly concealed in the deep cavity of the 

 clasper (PI. XL. f. 0) ; it ends in two strong, long, conical processes which point 

 upwards. Penis-sheath (PI. XXX. f. 30) armed with a small, subapical, denticulate, 

 transverse ridge which is higher at the left side : penis-fnnnel (p-f) on each .side 

 with a curved, pointed, flattened process.

(S ? . Anal angle of forewing produced backwards as a broad lobe. Tlie 

 hindwing has three straight oblique lines on the underside ; they are equidistant, 

 the first being subbasal. The presence of this subbasal line is very remarkable, 

 inasmuch as there is no such line in any other Ambulicine species, the most 

 pro.\imal line of the other Amhiilirimie standing always distally of the base of 

 M-. The red colour of the basal half of the underside of the forewing, and of the 

 npperside of the hindwing, illustrates conspicuously tlie peculiar ])heuomenon so 

 widely occurring among Lejiidoptera that the iippersiih- of the hindwing resembles 

 in colour the iiinlersii/p of the forewing as regards the hasal areas of botli wings.

The sjiecies is rare. We receive<l from Mons. t'harles Oherfhiir a 6 labelled 

 Narjiliug, foret, 13. iv. 1882 (A. Desgodius). The insect is apparently an early one, 

 and that may )iartly account for its scarcity in collections. It is possible that one 

 nniy succeed in attracting specimens by a lamp after midnight, many AiiiljitUcinae 

 occurring oidy very late in the night.
