obliquely at the top ; the dorsal ridge sinuous, with a distinct swelling in the middle 
followed by a somewhat blunt apex, which reaches to the tip of the abdomen ; the 
surface much punctured, with the outer edges fringed with a white tomentose pile; 
these white stripes are united near the insertions of the tegmina, so as to form a mark 
like a W, whence the specific name. 
The tegmina are concolorous with the pronotum ; each has a white dot in the disc 
followed by a white striga near the apex ; wings semi-transparent, smoky, with 
black neuration ; the abdomen dark grey ; the legs with dark femora and tarsi ; the 
tibiae paler grey. 
Size, with expanded wings, 1G x 8 mm. 
Habitat. —Ecuador, 10,000 feet. 
Bosenberg Collection. 
The few species as above described form only a part of this genus, which has 
numerous representatives but often very partially diagnosed. Mr. W. F. Kirby has 
assisted in cataloguing as many as 52 species, without including others of doubtful 
synonymy. 
Canon Fowler figures 14 species. The limits of this monograph prevent more 
than the names of such as do not appear in it, as figured. The works of Fairmaire, 
Walker, Butler, Stal, and Fowler may be consulted for further details.
