 ded at costa into dark grey spot. Upper surface of hind wing buff (holotype) or greyish buff, 

 speckled with dark grey ; area between transverse fasciae grey ; sub-basal fascia and ante- 

 medial fascia edged proximally and distally respectively with greyish white ; posterior cell-spot 

 dark brown. Under surface of fore wing buff (holotype) or greyish buff, heavily speckled proxi- 

 mally with dark grey ; well marked grey postmedial fascia. Ground-colour of under surface of 

 hind wing as fore wing ; well marked, dark brown, discocellular spot and posterior cell-spot ;

6* genitalia (Text-figs. 2oi— 203) : valve with two arcuate medial processes, vesica with single 

 hooked cornutus ; eighth abdominal sternum as in figure. 



$. Not known. 



Measurements. A.P.R. : $. 10. Wing : $. i8-o, 16-5-19-0 mm. (3). 



Discussion. Although externally unlike boboa in many respects, comparison of 

 the genitalia indicates that canescens may have close affinities with boboa.

Crocinis imaitsoana sp. n. 



(Text-figs. 204-206 ; PL 11, fig. 314) 



Description. <$. Palp and front of head orange-brown (holotype) or reddish brown ; 

 vertex of head and proximal half of upper surface of antennal shaft slightly paler than palp ; 

 distal half of antennal shaft buff. 



Dorsal surface of thorax dull orange (holotype) or brown, scales tipped with light grey on 

 anterior part of thorax ; pale pinkish buff ventrally, but reddish brown anteriorly. Front 

 surface of all legs proximal to tarsus pinkish brown, remaining surfaces pale buff ; all tibiae pale 

 buff except for last segment which is pinkish brown distally ; fore legs more intensely coloured 

 than mid or hind legs. Outer margin of fore wing moderately convex (Plate 11, fig. 314). 

 Upper surface of fore wing lustrous distal to antemedial fascia ; ground-colour yellowish brown 

 or orange (holotype) lightly speckled with dark brown, orange-brown between medial fasciae in 

 holotype ; antemedial fascia dark brown edged proximally with white ; hyaline patch bordered 

 by non-lustrous reddish brown scales ; postmedial fascia black (holotype) or dark brown, edged 

 distally with white, especially noticeable at apex, fascia bent inwards near apex of wing ; colour 

 of fringe doubtful. Outer margin of hind wing concave posteriorly ; upper surface yellowish 

 brown or orange-brown (holotype), with broad, slightly paler, yellowish brown or orange (holo- 

 type) marginal band and pale buff basal area, lightly speckled with dark brown ; area between 

 transverse fasciae of holotype darker than rest of wing ; trace of dark sub-basal fascia edged 

 proximally with white ; well-marked brown or black (holotype) antemedial fascia edged distally 

 with white ; colour of fringe doubtful. Under surface of both wings dull pinkish buff, speckled 

 with grey ; weakly marked postmedial fascia on both wings.
