98. Botys credulalis, nov. spec. 



A male of 26 mm. expanse. 



Palpi reciirved, brownish, nearly miicolorous, as only the begin- 

 ning of the base is whitish. Antennae two-thirds of fore wings, 

 setaceous, brownish grey. Upper side clear brownish grey, some- 

 what glossy, nearly unicolorous ; only the costa of fore wings after 

 the first line is paler sordid luteous, which colour vanishes towards 

 the apex. The markings, a comma-form discal spot of fore wings, 

 a punctiform on hind wings, and the lines are black ; the first line 

 is broken on costa of discoidal cell, thence perpendicular ; second 

 line beginning at three-fourths of costa, perpendicular till a curve 

 on vein 3, thence nearly straight and obliquely directed to two- 

 thirds of the inner margin of hind wings ; it is a little diffused and 

 widened on hind wings ; marginal line pale yellow, slender, distinct, 

 basally shaded with blackish grey. Fringes blackish grey. Under 

 side of wings much paler and purer grey, the costa unicolorous, the 

 markings as above, less distinct. Body and legs also pale grey,

 ground colour. Palpi recui'ved, luteous, only the base indistinctly 

 white. Antennae setaceous, with short ciliations. Head and upper 

 side of body and wings luteous, the wings a little iridescent, paler
