the different form and position of the lines ; and also by the pure white 

 of the wings beneath; only marked by the discal dot, and ochreous 

 costal margin. 



Acidalia cacuminaria (sp. nov.). 



Expanse 22 mm. Length of body 9 mm. 



Palpi and front black ; antennas and vertex dirty white ; collar 

 black. Body above and beneath uniform dirty white. Anterior 

 legs in front black ; behind whitish. The remaining legs white, with 

 a black spot at the junction of the tarsi with the tibise. Abdo- 

 men with a row of dorsal black spots, one to each segment. Wings 

 above shining, dirty white, with a very slight tinge of ochreous; ir- 

 regularly sprinkled with black atoms. Anterior wings elongated, 

 pointed at the apex. The extra-basal line represented by a faint 

 black spot on the inner margin, and another, black, distinct, on the 

 median nervure; the two are connected by a faint reddish brown line. 

 This line is not continued to the costal margin, but stops at the me- 

 dian nervure. The discal dot black, distinct. The median shade is 

 represented by an oblique, reddish brown line, commencing on the 

 middle of the inner margin, and crossing the wing beyond the discal 

 dot. This line is thickened on the inner margin, where it is most 

 distinct, gradually becoming fainter as it proceeds, and ceasing 

 shortly before the costal margin. It is much more oblique than is 

 usual in this genus, and if continued would reach the costa a short 

 distance before the apex. Beyond this line another, black, oblique, 

 broadly undulating, extending to the apex. From the inner margin 

 to the fourth median nervule it is continuous, from that point to the 

 apex it is represented by small black dots on the nervules. Beyond 

 this line a broad band, composed of black, irregular, poorly defined 

 blotches; very conspicuous on the inner margin, and covering the 

 inner angle, becoming gradually extinct before the first median 

 nervule. There is a slight tinge of reddish brown between the larger 

 of these blotches. A series of black, very distinct, marginal dots be- 

 tween the nervules, that between the submedian nervure and fourth 

 median nervule being double. Posterior wings elongated; costal 

 angle rounded. A very acute angle at the termination of the second 

 median nervule. Between this angle and the costal angle the wing 

 is deeply concave; from the marginal angle to the anal angle the 

 margin is straight. Anal angle but little rounded. Abdominal mar- 

 gin nearly straight. Wings crossed by four undulating lines, inter- 

 rupted by the nervules; all of which are more conspicuous on the
