While multiseripia is geucrally regarded as distinct from scitiscripta^ I think that if Professor 
MWey had had examples of scifiscrqita^ before him he would have hesitated about describiug the 
melanotic specimens, as 1 believe them to be, under a different name. 
C, catidida only apxiears to differ from scitiscrijda in the tliorax being white and in having no 
dots on the hind wings (two $ collected in Florida by Mrs. Slosson). 
Moth, — Five S, Head wliite above; sides, below, and breast black. Thorax: collar white, 
edged with black behind, and two rows of spots more or less connected (in var, Candida^ 
according to Lintner, the thorax is entirely white). 
Fore wings without the usual broad median black band; snow-white, crossed b.v four 
scalloped, more or less perfect, lines within, and by four scalloped lines without the ring-like discal 
mark. The outer mark or submarginal line heavier on the costal and inner edge. Second and 
third lines forming a moi'e or less perfect series of ringlets and sometimes [mtiUiscripta) filled in 
with scattered fine black scales, giving the band thus formed a dusky hue. Fringe white, with 
more or less intravenular dots. 
Hind wings varying from white to uniformly dusky or smoky, with distinct heavy black dots 
(one from Florida is without any dots, this being var. Candida Lintner). Underside snow-white, 
with heavy black costal spots, the outer one forming a submarginal line extending to the median 
vein, both wings dark smoky with the darker diffuse lines on each wing, and a diffuse discal mark. 
Expanse of wings, ^ 28-35 mm.: length of body, ^ 13-19 mm, I add Riley’s description of 
his G, multiscripta. 
‘‘ Color white, with browu-black and black markings. Primaries white, slightly silvery, crossed 
with eight irregularly undulate and augulate narrow black lines, as follows: 1, basal, obsolete on 
costal and inner borders and preceded by' a black spot close to thorax; 2, reaching to both borders, 
but broken; 3, 4, and 5, proximate, and irregularly undulating almost straight across the basal 
fourth of wing, 3 and 4 thickened and confluent toward costa and generally forming a circular 
spot between subcostal and cubital veins; G, 7, and 8, obliciuing more toward apex, luuulate and 
more widely separated between veins 2, 3, and 4, more approximate and retreating toward base 
between veins 1 and 2 and 4 and 6, and generally so close along vein 2 as to coalesce; broader, 
more intense, irregular marks occupy the spaces toward apex and anal angle, left by’’ the retreating 
of line 8, thus leaving a regularly defined terminal space. Veins mure or less dusted with black 
and conspicuously marked in terminal space. A distinct row of terminal spots between the veins. 
The median space between lines 5 and 6 is about as wide as the terminal, and has a small discal
