pale ochreous, as in the allied species, basally margined by a waved 

 dark grey line, which is more distinct towards the apices of the 

 wings. Behind the second line of the fore wings, the discal line of 

 the hind wings and the hind margin, the ground is clouded with 

 pale fuscous. Fringes pale grey.

234. Oligostigma saturatalis, nov. spec. 



A female of 25 mm. expanse. 



This genus comes next to simplicialis, SnelL, and latifascialis, 

 Snell. (Tyds. v. Ent., 19, pp. 189 and 201) ; it differs from the first 

 by the very broad deep ochreous central fascia of hind wings, 

 which is still broader than in latifascialis, leaving only a narrow 

 streak of the lustrous white gi'ound colour between it and the black 

 bordered yellow margin ; this margin is marked with three white 

 black-margined spots, as in simplicialis (in latifascialis with two), 

 and the trigonous central patch of fore wings is also shaped as in 

 the first species ; it is deep ochreous, with sinuous dark grey basal 

 and hind borders, extending till the costa. All other markings are 

 deep, dull, pure ochreous yellow, and consist, on fore wings, of 

 three stripes along the costa and inner margin, while the third, 

 narrower and curved, is found in cell 1 b ; these are all without 

 darker margins. Two others are parallel to the hind juargin, and 

 of these the interior has only a slender black margin at the out- 

 side ; the exterior has them on both sides, slender, distinct, and 

 waved. Fringes dark grey, with a darker spot at the apex. On 

 hind wings the central yellow fascia is diffused over the apical 

 third, and the fringes are grey, with a darker basal line. Veins
