St. variabills Sm. (22 e) is on a bluish-grey ground densely strewn with greyish-brown, in the discal variabilis. 
area except the costal and proximal margins dusted with brownish-grey, and with black-striped veins; the 
single transverse lines are on the averted sides bordered with grey; the grey, darker strewn maculae approach 
each other with their lower ends; the grey undulate line is proximally bordered with black. The whitish hind¬ 
wing is tinted reddish and strewn with brown. Colorado. 
36. Genus: Morrlsonia Grt. 
Very closely allied to the preceding genus from which it chiefly differs by the collar being only feebly 
keeled and a parted tuft on the thorax. American, but some species from New Zealand were included therein, 
which we have enumerated among the Maoria in Vol. XI, p. 77 seq. 
M. mucens Hbn. (= multifaria Wkr., spoliata Wkr.) (22 e) has whitish forewings more or less dusted mucens. 
with red-brown, with a black basal ray and dentate transverse lines being double at the costal margin, both 
connected by a prolongation of the coniform macula; the two upper maculae are surrounded with dark brown. 
Hindwing light brown, at the margin darker. From the Central to the Southern United States. 
M. sectilis Gn. (= rileyana Sm.) (22 e). Forewing ochreous-yellowish, dusted with reddish-brown, sedilis. 
with a dark red-brown and black longitudinal shade in the submedian space, a black basal ray and dentate, 
at the costal margin double transverse lines, the distal line being distally whitish towards the proximal margin; 
the maculae are pupilled reddish, the ring-macula is large, obliquely elliptical, above open; instead of the undu¬ 
late line small dark triangular spots in the centre of the margin. Hindwing yellowish greyish-brown, at the 
margin somewhat darker. Missouri, Texas. 
M. albidior B. & McD. (= sectilana Strd.) is very similar to sectilis, smaller and of a much purer albidior. 
white ground-colour, but slightly tinted reddish. From Arizona. Compare what has been said in E. diplogramma 
Schs. (p. 135). 
M. bisulca Grt. (22 e) has grey forewings dusted with reddish and dark brown, with black-striped veins bisvlca. 
and a long black basal ray; the transverse lines are quite indistinct, whitish, the posterior line is dentate; between 
the small white maculae encircled with black there is a black stripe connecting them; the marginal area behind 
the undulate line is darker with black internerval streaks. Hindwing brown, towards the base grey. Arizona. 
M. evieta Grt. (22 f). Forewing red-brown, dusted with white, particularly near the base of the costal cvicta. 
margin, the cell filled up with yellowish; a basal ray and the veins are black; the transverse lines are indistinct 
and interrupted, the posterior line with white dots on the veins, the yellowish maculae are in whitish rings 
and above and below encircled with black, the ring-macula is prolonged towards the base and with a black 
streak below it, below confluent with the reniform macula; marginal area darkened with black internerval 
streaks which grow shorter towards the costal margin. Hindwing light brown, at the margin darker. Canada, 
New York. — vomerina Grt. exhibits the more extensive white costal-marginal area in bright contrast with vomerina. 
the blackish proximal-marginal part. — infidelis Grt. (22 f) is more purple brown, at the costal margin grey, infidelis. 
the maculae not being confluent. Michigan. 
M. confusa Hbn. (= infructuosa Wkr.) (22 f) has grey forewings dusted with red-brown and strewn confusa. 
with black, with black-striped veins and basal ray; the transverse stripes are very strongly dentate, the posterior 
stripe distally bordered with ochreous, the maculae in ochreous rings: the light undulate line shows a distinct 
W, behind it the marginal area is darker with black internerval streaks; fringes speckled ochreous-yellow. 
Hindwing light brown, margin and veins darker. Canada to California. — The claret-coloured larva with fine 
white longitudinal stripes lives on willows etc. 
37. Genus: Xylomygrs Gn. 
Like Morrlsonia, but with but one tuft on the 1st abdominal ring and loose tufts on the prothorax 
and metathorax. Only North American species. 
X. behrensiana Grt. (22 f). Forewing brownish-grey, as far as the whitish undulate line dusted with behrensia- 
brown and densely strewn and striated with blackish-brown, with a light costal margin, the transverse lines 
bordered with whitish, the posterior double line being filled up with whitish; the maculae are encircled with 
whitish and confluent, the veins of the marginal area strewn Avitli white. Hindwing light reddish, at the margin 
strewn with dark. California. 
X. erythrolita Grt. (22 f) is a smaller, uncommonly variable, in the typical form dark purple grey erythrolita. 
species strewn with brown; the indistinct transverse lines are only marked by dark costal-marginal spots, the 
posterior line by dots on the veins; the small dark maculae are encircled with ochreous-grey, the whitish inter¬ 
rupted undulate line is proximally spotted brown. Hindwing greyish-brown, at the margin darker. — apicata apicaia. 
Sm .. (= ab. 1 Hm/ps., erythrolitoides Strd.) (22 f) is of a redder ground-colour and on the whole somewhat
