extending all ronnd tiic ventral side ul' the segment, the liasal and ai)icai 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 few .yi/nes at 

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

 very short, oz/c pair to hindtibia ; jjulvillns and paronychium present, ('ell of 

 hindwing broad, lower angle not acute, about 90", R- from centre of cell, stalk 

 of SC- and 11' rather short. Distal margin of forewing dentate. Scales of 

 abdomiiial tergites long, no broad nnderscales, a])ical spines weak. 



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

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

 edge incrassate, rounded, (y'lasper without friction-scales, apical half narrower than 

 basal half, also less chitinised ; iiarpe nearly concealed in the deep cavity of the 

 clasper (PI. XL. f. 9) ; it ends in two strong, long, conical processes whicli jioint 

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

 transverse ridge which is higher at the left side r ]ienis-fnnnel (i'-f) on each side 

 with a curved, pointed, flattened process.

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

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

 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 

 proximal line of the other Ambulicinac standing always distally of the base of 

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

 uj)perside of the hindwing, illustrates conspicuously the jieculiar plienomenon so 

 widely occurring among Lepidoptera that the tijipersidi' of the hindwing resembh's 

 in colour the iimU'r-vilc of the forewing as regards the basal areas of liotli wings.

The species is rare. We received from Mons. Charles Oberthiir a i labelled 

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

 and that may partly account for its scarcity in collections. It is possible tiiat one 

 may succeed in attracting specimens by a lamp after midnight, many Ambulicinae 

 occurring only very late in the night.
