black lines are always continuous and strongly marked; in olivacearia 

 they are represented by black spots on the nervules, and although in 

 several cases one of the lines is continuous, the others on the same 

 specimen are disconnected and rudimentary. There are several other 

 distinctions between the two, which are, however, not always constant. 

 In strigataria, three lines on the posteriors above are nearly always 

 present; in olivacearia there is very rarely more than one, and that is 

 often absent. In strigataria the lines are partially reproduced be- 

 neath; in olivacearia, they are absent. In olivacearia the two sub- 

 marginal bands of the anterior s form a constant and conspicuous 

 feature; in strigataria there is seldom more than one present, and 

 that is frequently vague and little marked. As I am not sure of the 

 identity of my female strigataria, I cannot draw a comparison between 

 the females of the two species. 



Fifteen males, twenty-five females of olivacearia, and five males, 

 one female of strigataria were examined. 



Genus Cidaria. 



Cidaria albo-punctata (sp. nov.). 



Expanse, 32 mm. Length of body, 12 mm. 



Palpi dark brown. Front, vertex and collar, light yellowish 

 brown. Antennas dark brown, becoming lighter at the tip; in the 

 female simple, in the male the first two-thirds are pectinated, the last 

 third simple. Body yellowish brown, sparsely sprinkled with fine 

 black atoms. Ground color of the wings white, tinged on the costa, 

 apex and submarginal region, with light yellowish brown. Anterior 

 wings with the base covered with brown spots and striae. A black 

 diffused spot in the centre of the base, immediately adjoining the 

 white sub-basal band. This spot is sometimes only represented by 

 an accumulation of the brown striaa. Interior line black, very dis- 

 tinct, reflexed on the costal margin, then proceeding in a regular 

 undulating curve, to the centre of the interspace, between the sub- 

 median nervure and fourth median nervule. At this point (in about 

 one-half the specimens I have examined) a narrow white arm pro- 

 jects outwardly, about one-half of the distance to the exterior line ; 

 from this arm the interior line first curves inwardly, and then drops 

 almost perpendicularly to the inner margin. The interior line is 

 broadly bordered internally with white. In one specimen there 

 is another narrow arm, situated in the discal space and extend-
