collected in Chili. 407 



The following species has much perplexed me ; it has 

 the coloration of Aleiicis, with more nearly the aspect of 

 Scodioua, but in structure it agrees with Cheimatobia, to 

 which genus I therefore refer it. 



Cheimatobia, Stephens. 



101. CJieimatohia aleucidia, n. s. 



Shining grey ; the body, primaries, and fringe of 

 secondaries with bronze-brown reflections ; primaries 

 completely covered by numerous parallel undulated dark 

 grey lines, two of which in the middle of the wing are 

 more defined than the others, and commence in blackish 

 costal spots ; a blackish disco-cellular spot ; all the 

 wings with a blackish marginal line ; head, collar, and 

 shoulders dark brown ; under surface uniform leaden 

 grey. Expanse of wings, 23 mm.

Theea, Stephens. 



102. Thera coufusa, n. s. 



(? . Allied to r. variata, but all the markings of the 

 primaries somewhat obscured by black and grey mottling ; 

 the subbasal area (and not the central belt) darker than 

 the rest of the wing, blackish, wider than in T. variata, 

 so as to reduce the width of the anterior part of the belt 

 and throw it further forward ; the latter scarcely separable 

 from the disc, excepting by a slender black line of the 

 usual form ; external area greyish ; submarginal dentate- 

 sinuate white line straighter, not increased towards the 

 costa as in T. variata ; secondaries rather broader, white, 

 grey-speckled, and crossed from the basal third by three 

 grey lines, the innermost regularly arched, and the two 

 others irregularly undulated and indistinct ; thorax 

 greyish brown ; abdomen whitish ; primaries below grey ; 

 costal border whitish, speckled with dark grey ; two in- 

 distinct dusky stripes, both more or less diffused, the 

 first just beyond the basal third, indistinct ; the second, 

 which is angulated, across the disc ; a small blackish 

 disco-cellular spot ; fringe white, spotted with black ; 

 secondaries white, grey-speckled, and crossed by two 

 dark grey lines, the first at basal third curved, the 

 second across the disc irregularly arched and undulated ;
