160 THE ENTOlVtOLOGIST. 



contains one rather conspicuous dot on each side of the 

 medio-dorsal pair ; the second lateral pair is sinuous, inter- 

 rupted, indistinct ; the 2nd, 3rd and 4th segments have a 

 decided dark lateral, or perhaps rather subdorsal, stripe, 

 common to all three ; the 9th segment has a very decided 

 whitish space occupying each posterior angle ; the 10th seg- 

 ment has a double black dot on each side. The ventral is 

 rather more variegated than the dorsal area, but its markings 

 are less constant ; there is a raedio-ventral stripe, extending 

 from the 4th to the 10th segment, almost white, but this 

 is interrupted at the interstices of the segments by a darker 

 transverse band ; and each of these darkeV bands resolves 

 itself into dull brown ground colour, and several longitudinal 

 series of intensely black dots ; none of these series contain 

 more than five of the black dots, and some have only three ; 

 these dots form portions of sinuous, but interrupted, stripes, 

 very similar to those described on the dorsal area ; the feet 

 and claspers are much the same colour as the body.] The 

 moth appears on the wing in June and July, flying at dusk. 

 The male expands from three-fourths of an inch to one inch ; 

 the female [? mancuniata] is smaller. Head and face dark ; 

 anteunai setaceous and light-coloured ; the collar ochreous ; 

 the thorax and wings rich creamy white, sometimes smoky; 

 fore wings somewhat rounded on the costa, which is slightly 

 ochreous along its outer edge; tips of wings produced, 

 rather pointed (in the female less so, rather rounded) ; the 

 lore wings have five suffused, but definite, strigge ; the first, 

 placed on the first third of the wing, is oblique from the base 

 to near the costal nerve, where it turns quickly inwards; the 

 second runs through the centre of the wing, and this and the 

 three outer striga? are about equidistant and slightly waved : 

 hind wings rounded, with only four strigse in the majority of 

 specimens, though in a few I have observed a fifth as well 

 defined as the other four ; all the wings are irrorated with 

 yellowish or darkish atoms, and have a series of well-defined 

 small cilia-spots at the base of the cilia, nine on each wing : 

 the abdomen is of the same colour as the wings ; the legs 

 are dark yellowish ashy. Under side : chest ashy ; the fore 

 wings suffused with smoky, darkest on the basal costa, with 

 two or more strigaj, one of them well-defined, and having a 

 central spot on eacii wing, which spot is sometimes percep-
